An E-max dental veneer is one of the lithium disilicate-based all-ceramic restoration options that can be used especially in front teeth where the aesthetic expectation is high. Thanks to its light transmission and reflection properties, it can help achieve an appearance close to natural tooth enamel in suitable patients.

E-max is not merely a “white tooth covering”. Depending on the structural condition of the tooth and the planned treatment, it can be prepared as a full crown, a porcelain laminate veneer, an inlay, an onlay or a partial crown. For this reason, before a patient’s request of “I want E-max”, it should be determined which type of restoration they actually need.

If only a mild colour or shape change is wanted on a largely intact front tooth, a thin E-max laminate veneer can be considered. In cases where the tooth has a large filling, is fractured or is structurally weak, an E-max crown that encircles the tooth more widely may be needed. Even if the same material is used, the amount of tooth tissue removed and the way of application are not the same in these two treatments.

Clinical studies on lithium disilicate restorations show that when correct case selection and suitable bonding protocols are used, high survival rates are reported for single-tooth crowns and porcelain laminate veneers. However, success depends not only on the material but on the preparation of the tooth, the thickness of the restoration, the amount of bonding to enamel, occlusal forces and the patient’s care habits.

In the E-max veneer assessments carried out at Dentapolitan in Istanbul, not only the colour of the teeth but the remaining healthy enamel tissue, gum health, the smile line, lip structure, facial proportions, jaw occlusion and clenching findings are evaluated together.

What is an E-max dental veneer?

E-max is a lithium disilicate-based glass-ceramic system used in dentistry. It contains no metal substructure and the entire restoration is made of tooth-coloured ceramic material.

The glass-ceramic structure of lithium disilicate gives the restoration both aesthetic properties and a certain mechanical durability. The material can be prepared by heat-pressing in the laboratory or by milling with computer-aided design and manufacturing systems.

E-max restorations can be applied in the following forms:

• Full dental crown
• Porcelain laminate veneer
• Inlay
• Onlay
• Overlay or partial crown
• Single crown on an implant under suitable conditions
• Selected short restorations

When E-max veneer is mentioned, most patients think of a full crown. However, one of the most important features of the treatment is that, in suitable cases, more conservative restorations can be prepared without covering the entire tooth.

Are an E-max crown and an E-max laminate veneer the same thing?

No. Even if the two restorations can be produced from the same material, the ways they cover the tooth are different.

E-max crown

An E-max crown is an all-ceramic restoration that encircles most of the visible part of the tooth.

It is generally considered in the following situations:

• If there is a large filling in the tooth
• If there is a significant loss of substance
• If the tooth is fractured
• If an old crown is to be replaced
• If advanced discolouration needs to be masked
• If the tooth needs circumferential support

To make a full crown, a controlled amount of tissue must be removed from the different surfaces of the tooth.

E-max laminate veneer

An E-max laminate veneer is a thin ceramic restoration usually bonded only to the front surface of the tooth.

It can be considered in the following situations:

• If the tooth is largely intact
• If a mild or moderate shape change is wanted
• If there is discolouration that cannot be removed by whitening
• If small gaps are to be closed
• If there is sufficient enamel tissue
• If the occlusal relationships are suitable

In the clinical success of porcelain laminate veneers, it is important that the restoration is bonded to the enamel surface as much as possible. Too much exposure of the dentin surface can negatively affect the success rate.

For this reason, the statement “the teeth are not reduced at all with an E-max veneer” is not correct. In laminate cases, tooth preparation may not be done at all or may be very limited; in a full crown, more space is created for the restoration.

To which teeth can E-max be applied?

E-max can be considered especially in the following regions where the aesthetic expectation is high:

• Front incisors
• Canines
• Premolars
• Single molars under suitable conditions
• Single-tooth crowns visible in the smile line
• Front-tooth porcelain laminate veneers
• Back-tooth inlays and onlays

The area of use of the material is not determined only by whether the tooth is in the front or back region. The thickness of the restoration, the remaining tooth tissue, occlusal forces, the habit of clenching and whether the restoration is a single tooth or a bridge should be evaluated together.

E-max has a broad area of use especially in single-tooth restorations. In long bridges, on the other hand, because of the mechanical limits of lithium disilicate, different materials such as zirconia or metal-ceramic may be more suitable. Systematic reviews published on lithium disilicate crowns report supportive clinical results for single crowns but show that the evidence on multi-unit fixed prostheses is more limited.

In which situations can an E-max veneer be applied?

E-max treatment can be considered in the following situations:

• Advanced discolouration in front teeth
• A disorder in tooth shape or size
• Small teeth
• Limited gaps between front teeth
• Fractured front teeth
• Teeth with large fillings
• Worn teeth
• Old and aesthetically mismatched veneers
• Enamel developmental disorders
• Mild position disorders in suitable patients
• Teeth requiring sufficient support after root canal treatment
• The need for an inlay, onlay or partial crown in back teeth

Not every aesthetic problem should be treated with an E-max veneer. For example, if there is marked crowding or a jaw-relationship disorder, orthodontic treatment may be more conservative and more biologically appropriate.

In a patient who is only bothered by tooth colour, teeth whitening should be considered first. In small fractures or shape disorders, direct composite restoration may be sufficient.

Who may E-max treatment not be suitable for?

E-max may not be the first choice in some clinical situations.

The situations that should be carefully evaluated are:

• Active gum disease
• Untreated decay
• Infection at the root tip
• Advanced bone loss and tooth mobility
• A fracture too deep to be restored
• Very little healthy tooth tissue remaining
• Insufficient restoration thickness
• Severe and uncontrolled bruxism
• Very high chewing forces
• The need for a long bridge
• Masking of a very dark metal or tooth substructure
• Very limited enamel tissue
• Insufficient oral hygiene
• Mild aesthetic problems that can be corrected with more conservative treatment

Some of these situations are not absolute contraindications. For example, in a patient with bruxism, E-max can be used with suitable thickness, occlusion adjustment and a protective night guard. However, the risks must be clearly explained to the patient.

How is planning done before E-max?

In E-max restorations, the preservation of tooth tissue and long-term bonding success are as important as the aesthetic result.

At the first examination, the following are evaluated:

• Decay, fractures and old fillings
• The amount of remaining enamel and dentin
• The vitality of the tooth
• The need for root canal treatment
• Root and periodontal bone support
• Gum health
• The amount of gum visible during the smile
• The colour and shape of the teeth
• Lip and facial proportions
• The dental midline
• The lower and upper jaw relationship
• Jaw movements
• Occlusal contacts
• Clenching and grinding
• The patient’s aesthetic expectations

When necessary, intraoral radiographs, panoramic imaging, digital intraoral scanning, photographs and occlusal records are used.

In cases where more than one front tooth will be changed, a digital smile design or a temporary mock-up can be done. In this way, the length and width of the teeth, lip support and harmony with the face can be evaluated before the permanent procedure.

Digital design does not replace the clinical decision. The designed teeth must have sufficient space, biological compatibility and functional occlusion in the mouth.

How is an E-max veneer made?

The treatment process varies according to whether the restoration is a crown, laminate veneer, inlay or onlay.

1. Preparation of tooth and gum health

Active decay, infections and gum problems are treated first.

Impressions taken while gum bleeding and swelling continue can make it difficult to record the restoration margins accurately. Therefore, a healthy gum environment should be created before the impression or digital scan.

If an old veneer is to be renewed, the restoration is removed and the real condition of the tooth beneath is evaluated.

2. Determining the type of restoration

It is decided how much of the tooth will be covered:

• A laminate veneer if only the front surface is needed
• An inlay or onlay if a part of the chewing surface is needed
• A full crown if the tooth needs circumferential support

The aim is not to remove healthy tooth tissue that is not necessary for the treatment.

3. Preparation of the tooth

The space needed for the restoration is created in a controlled way.

The amount of tooth tissue to be removed varies according to the following factors:

• The type of restoration
• The required thickness of the E-max material
• The current colour of the tooth
• The position of the tooth in the mouth
• The amount of decay and filling
• The planned tooth shape
• The occlusal distance
• The need to preserve enamel tissue

In laminate applications, the aim is to stay within the enamel borders as much as possible. In a full crown, a suitable tooth form is created that will carry the restoration circumferentially.

4. Digital scanning or impression

The prepared teeth can be recorded with a digital intraoral scanner or a conventional impression can be taken.

It is reported that lithium disilicate crowns can be produced by the press or CAD/CAM method and that both methods can provide a clinically acceptable marginal fit. In addition to the production method, tooth preparation, the accuracy of the impression and the laboratory design also affect the fit of the restoration.

5. Temporary restoration

In full crown or comprehensive laminate cases, temporary teeth can be made until the permanent restorations are prepared.

Temporary restorations:

• Protect the prepared tooth.
• Can reduce sensitivity.
• Maintain the aesthetic appearance.
• Prevent the teeth from shifting.
• Help evaluate the planned shape and occlusion.

6. Try-in

Before the E-max restoration is bonded, the following elements are evaluated:

• Seating on the tooth
• Marginal fit
• Contact with neighbouring teeth
• Occlusion
• Colour
• Light transmission
• The shape of the tooth
• Surface texture
• The smile line
• Speech
• The relationship with the lips

There can be a difference between trying the restoration in a dry environment and its appearance after being bonded in the mouth. Therefore, colour evaluation can be done with suitable try-in pastes.

7. Adhesive bonding

Because E-max has a glass-ceramic structure, it can be strongly bonded to the tooth with resin-based cements after suitable surface treatments.

The inner surface of the restoration is prepared according to the manufacturer’s protocol. Adhesive procedures suitable for the amount of enamel and dentin are also applied to the tooth surface.

In porcelain laminate veneers, the surface treatment and adhesive bonding protocol are decisive for clinical success. In lithium disilicate and other glass-ceramic laminate veneers, suitable etching and silane application are important for bonding.

How much are the teeth reduced with an E-max veneer?

There is no single amount of reduction. Because E-max can be used in both very conservative laminate veneers and full crowns, the amount of tooth tissue removed varies considerably according to the type of treatment.

In laminate application

• In some suitable teeth, no preparation may be done.
• In some teeth, only limited reduction within the enamel may be done.
• A tooth that is protruded or in a crowded position may require more preparation.
• It cannot be said that “because it is a wafer-thin porcelain, the tooth is never touched”.

In full crown application

• Space is created from the front, back, side and chewing surfaces of the tooth.
• Extra thickness may be needed to mask a dark tooth.
• Sufficient space must be provided so that the restoration does not fracture and does not look overly bulky.
• As much healthy tooth tissue as possible should be preserved.

In young and healthy teeth, whitening, orthodontics, composite or laminate options should be evaluated before a full crown is made only for a colour or small shape change.

Does an E-max veneer look natural?

One of the important features of E-max is that its light transmission and optical properties are suitable for aesthetic restorations. In suitable cases, an appearance close to natural tooth enamel can be achieved.

However, a natural appearance does not depend only on the material.

The factors affecting the result are:

• The colour of the tooth beneath
• The thickness of the restoration
• The E-max opacity used
• The colour of the adhesive cement
• The surface texture of the teeth
• Colour transitions
• Incisal edge characteristics
• Harmony with neighbouring teeth
• The gum margin
• Facial and lip proportions
• The dentist’s and laboratory’s work

E-max can be produced with different opacity and light transmission options. More translucent materials can provide a natural appearance but may not sufficiently mask a dark substructure. Very opaque materials, on the other hand, may create a more artificial appearance while covering the dark colour.

For this reason, the same E-max block or the same colour should not be selected for every patient.

Can E-max cover dark-coloured teeth?

Teeth discoloured to a certain degree can be masked with suitable opacity and restoration thickness. However, not every dark tooth is ideal for E-max.

Masking can become difficult in the following situations:

• Advanced tetracycline staining
• A metal post and core structure
• A very dark root-canal-treated tooth
• A dark root appearance at the gum level
• Very limited thickness for the restoration
• A serious colour difference with neighbouring teeth

In these cases, more opaque E-max options, a zirconia substructure, different core materials or additional dental treatments can be considered.

Unnecessary tooth reduction should not be done to provide more masking. A balance must be struck between the aesthetic goal and the preservation of natural tooth tissue.

E-max or zirconium?

E-max and zirconia are different ceramic groups. It cannot be said that one is better than the other in every situation.

E-max

• Is a lithium disilicate-based glass-ceramic.
• Generally offers high light transmission.
• Can be bonded adhesively to the tooth.
• Can be considered in front-tooth crowns and laminate veneers.
• Can be used in conservative restorations such as inlays and onlays.
• Is not always suitable for long bridges.
• Masking can be limited in very dark substructures.

Zirconium

• Is a zirconium dioxide-based polycrystalline ceramic.
• Generally has higher mechanical durability.
• May have a broader area of use in the back region, in restorations on implants and in suitable bridges.
• Can mask dark substructures more strongly.
• Has types with different levels of translucency and durability.
• Its very opaque types can look more artificial in the front region.

There is no strict rule that E-max will always be used in front teeth and zirconium always in back teeth. Material choice should be made according to the remaining tooth tissue, the thickness of the restoration, the colour of the tooth, bruxism and the form of the restoration to be made.

E-max or porcelain laminate veneer?

This question technically compares two different concepts.

E-max is the material system from which the restoration is produced.

A porcelain laminate veneer expresses the form of the restoration on the tooth.

A porcelain laminate veneer can be produced from E-max lithium disilicate. It can also be prepared from feldspathic porcelain or different glass-ceramics.

For this reason, the correct question is often:

• A full E-max crown?
• An E-max porcelain laminate veneer?

If the tooth is largely intact and an aesthetic change is needed only on its front surface, a laminate veneer may be more conservative. If there is a large filling, fracture or need for circumferential support, a full crown may be needed.

E-max or metal-ceramic?

E-max is an all-ceramic restoration without a metal substructure. Metal-ceramic, on the other hand, is prepared by layering porcelain over a metal substructure.

Areas where E-max can stand out

• High aesthetic expectation
• Front-tooth single crowns
• Sufficient enamel and dentin support
• The need for natural light transmission
• The need for adhesive bonding
• Laminate veneer, inlay and onlay restorations

Areas where metal-ceramic can be considered

• Masking of a very dark substructure
• Multi-unit bridges
• Cases where a long clinical use history is wanted
• Certain mechanical and prosthetic requirements
• The restoration space being suitable for a metal-ceramic design

Metal-ceramic is not an outdated or unsuccessful treatment. E-max is also not more aesthetic and longer-lasting in every situation. The choice should be made according to the needs of the tooth and the prosthesis.

What are the advantages of E-max?

In suitable cases, the advantages of E-max restorations are:

• Containing no metal substructure
• Light properties close to a natural tooth
• Different opacity options
• Being able to be bonded adhesively to the tooth
• Being usable as a full crown, laminate veneer, inlay and onlay
• Suitability for partial restorations that preserve healthy tooth tissue
• The possibility of aesthetic customisation in the front region
• The absence of a metal reflection at the gum margin
• Being able to be produced by the press and CAD/CAM methods
• The presence of supportive clinical data in single-tooth restorations

Recent meta-analyses on lithium disilicate laminate veneers have reported high long-term survival rates and acceptable complication rates. However, because the case selection and follow-up methods in the studies differ, a fixed success rate should not be given for every patient.

What are the limitations and risks of E-max?

E-max restorations have some limitations:

• The risk of fracture at an unsuitable thickness
• Increased mechanical load in severe bruxism
• Limited use in long bridges
• Difficulty in masking very dark substructures
• Insufficient enamel in laminate treatment
• Adhesive bonding requiring technical sensitivity
• The need for moisture control during bonding
• Temporary or permanent sensitivity
• Involvement of the tooth nerve
• Separation of the veneer
• Decay in the margin region
• Gum recession
• Colour or shape mismatch
• Wear on the opposing tooth
• A crack or fracture in the restoration

E-max is a high-strength glass-ceramic; but it is not an “unbreakable porcelain”. In particular, leaving the restoration thin, unsuitable tooth preparation and uncontrolled chewing forces can increase the risk of fracture.

Does an E-max dental veneer break?

Yes. Like every dental ceramic, E-max can break under unsuitable conditions.

Situations that can increase the risk:

• Insufficient restoration thickness
• Sharp tooth-preparation angles
• Unsuitable bonding
• A hard impact
• Breaking ice and hard shells
• Severe clenching
• Excessive force at a single point in occlusion
• A crack or flexure in the tooth beneath
• A long or unsuitable bridge design

Small surface damage can in some cases be repaired in the mouth. In large fractures, the restoration may need to be renewed.

Does an E-max veneer change colour?

The E-max ceramic itself does not yellow biologically like a natural tooth. However, plaque and external stains can accumulate on the surface.

Situations that can affect the appearance:

• Smoking and tobacco use
• Heavy tea and coffee consumption
• Deterioration of the surface polish
• Cleaning with abrasive products
• Colour change of the adhesive cement over time
• Gum recession
• Colour change of neighbouring natural teeth
• Changes in the tooth tissue beneath

E-max veneers are not lightened by teeth-whitening products. If whitening is to be done on natural teeth, it is more appropriate to complete the procedure before the veneer colour is determined.

Does a tooth decay under an E-max veneer?

Yes. The E-max material does not decay; but the natural tooth beneath it can decay.

The risk of decay can increase in the following situations:

• Plaque accumulation at the veneer margin
• Not using dental floss
• Deterioration of the marginal fit
• Gum recession
• Frequent sugar consumption
• Dry mouth
• Separation of the veneer
• Neglecting regular check-ups

The veneer is not a shell that protects the natural tooth against decay for life. In particular, the margin where the restoration meets the tooth must be cleaned.

Does an E-max veneer cause odour?

A well-fitting and regularly cleaned E-max veneer does not cause odour on its own.

Odour can be associated with the following:

• Plaque at the veneer margin
• Gum inflammation
• Decay under the veneer
• Not using dental floss
• Food accumulation in between
• Marginal misfit
• Dry mouth
• Insufficient cleaning of the tongue and other areas of the mouth

If there is a persistent bad taste, odour or gum bleeding, a clinical evaluation should be done.

Is root canal treatment necessary when making an E-max veneer?

Root canal treatment is not applied to every tooth that will receive an E-max veneer.

Root canal treatment may be necessary only in clinical situations such as:

• Irreversible pulp inflammation
• Infection at the root tip
• Deep decay
• Trauma
• Severe pain starting beforehand
• Loss of vitality of the nerve tissue

Performing routine root canal treatment on a healthy tooth just because an E-max crown will be made is not correct.

Short-term sensitivity may develop after tooth preparation. Pain that starts spontaneously, wakes you at night or gradually increases should be evaluated by the dentist.

Does clenching affect E-max veneers?

Bruxism is not always an obstacle to making E-max; but it can increase the risk of mechanical complications.

In patients who clench their teeth:

• Ceramic crack or fracture
• Separation of the veneer
• A crack in the natural tooth
• Wear on the opposing teeth
• A change in occlusal contacts
• Complaints of the jaw muscles and jaw joint

can be seen.

Before treatment, wear, muscle tenderness, jaw movements and occlusal relationships should be evaluated. In patients who need it, a protective night guard can be planned by changing the restoration thickness, material choice and occlusal design.

The approach “because E-max is strong, a night guard is not needed” is not correct.

How long does it take to make an E-max veneer?

The treatment time is not the same for every patient.

The factors affecting the time:

• The number of teeth to be treated
• Whether a crown or laminate veneer is made
• Gum treatment
• Treatment of decay and fillings
• The need for root canal treatment
• Removal of old veneers
• Temporary restorations
• The number of try-ins
• The press or CAD/CAM production method
• Laboratory customisation
• Smile and occlusion planning

A single E-max crown can be completed in a short time. In aesthetic rehabilitations involving many front teeth, on the other hand, more time may be needed because of the evaluation of temporary teeth and colour and shape try-ins.

A fixed duration should not be given to all patients for E-max; the treatment time should be explained according to individual need.

How long do E-max veneers last?

A definite period of use valid for every patient cannot be given for E-max restorations.

The main factors affecting the period of use:

• Whether the restoration is a crown or a laminate veneer
• The remaining healthy tooth tissue
• The amount of bonding to enamel
• The form of the tooth preparation
• The thickness of the restoration
• The bonding protocol
• Occlusal forces
• Bruxism
• Gum health
• Oral hygiene
• Regular check-ups

Systematic reviews on lithium disilicate full crowns report high clinical survival under suitable conditions. High survival rates have also been reported in long-term observations for lithium disilicate laminate veneers. However, “survival” does not mean the restoration was used without any maintenance, sensitivity, colour mismatch or minor complication.

Statements such as “an E-max veneer lasts for life” or “it is definitely used for 15–20 years” are not scientifically correct.

How should care be taken after E-max?

Because E-max restorations are in the same oral environment as natural teeth, they require regular care.

In daily care:

• The teeth should be brushed at least twice a day.
• The spaces between the teeth should be cleaned with dental floss or an interdental brush.
• Plaque should not be left at the veneer margins.
• Very hard objects should not be broken with the teeth.
• Nails, pens or packaging should not be bitten.
• If there is bruxism, a night guard should be used.
• Gum bleeding should not be neglected.
• Regular dental check-ups should be continued.

In professional cleaning, suitable materials that will not damage the ceramic surface should be used.

Why do E-max veneer prices vary in Istanbul?

The E-max price is not determined solely by the number of teeth to be treated.

The elements that can affect the cost are:

• Whether a full crown or laminate veneer is made
• Planning of an inlay, onlay or partial crown
• The number of teeth to be treated
• The front or back region
• The press or CAD/CAM production method
• The type of E-max block or ingot used
• Laboratory customisation
• Removal of old restorations
• The need for a filling or root canal treatment
• Gum treatment
• Temporary restorations
• Digital smile planning
• The number of try-ins and colour customisation
• Application on an implant or on a natural tooth

For patients researching E-max dental veneers in Istanbul, making only a price-per-tooth comparison is not enough.

The following questions should also be evaluated:

• Will the procedure be a full crown or a laminate veneer?
• How much tissue will be removed from the tooth?
• Are there alternative, more conservative treatments?
• Are temporary teeth included in the price?
• What is the type of material to be used?
• Will laboratory customisation be done?
• Is additional tooth or gum treatment needed?
• How will the check-ups be carried out?

Why should the face and occlusion be evaluated together in E-max planning in Istanbul?

Front-tooth restorations can affect not only the individual teeth in the mouth but also the person’s facial expression and speech.

In planning, the following relationships should be evaluated:

• The contact of the teeth with the lips
• The amount of visibility during the smile
• The facial and dental midline
• The length-to-width proportions of the teeth
• The relationship of the incisal edges with the lip
• Speech sounds such as “F”, “V”, “S”
• Front-tooth guidance
• The contact of the lower and upper front teeth
• Jaw movements
• Bruxism and chewing muscles

Preparing only very white and identically shaped teeth does not mean an aesthetic result. In a natural smile, there are individual transitions in the size, surface, light and colour properties of the teeth.

When E-max treatment is planned at Dentapolitan, the patient’s facial features, lip structure, existing tooth tissue, periodontal health and functional occlusion are evaluated together. Dentapolitan serves in Istanbul through its clinics in Bostancı, Ümraniye and Pendik.

E-max planning that preserves natural tooth tissue

The aim of E-max treatment is not only to make the front teeth whiter. In the right case, the aim is to preserve the damaged tooth, rebuild the necessary function and improve the aesthetic appearance in harmony with the patient’s face.

One of the important advantages of E-max is that, besides a full crown, it can also be used in more conservative restorations such as laminate veneers, inlays and onlays. However, the material being aesthetic does not justify covering every healthy tooth.

In some patients, an E-max crown may be the most suitable option. In another patient, a porcelain laminate veneer, composite restoration, teeth whitening, zirconium veneer or orthodontic treatment may be more appropriate.

The treatment decision should be made by evaluating together the clinical and radiological examination, the amount of remaining enamel and dentin, gum health, tooth colour, jaw occlusion, bruxism, the smile line and the patient’s expectations.
