Aesthetic  Teeth Filling Inlay/Onlay

Inlay and onlay aesthetic teeth fillings are divided into two categories based on the materials used in their content:

Porcelain inlay onlay fillings:

Similar to aesthetic porcelain crowns, this type of fillings is also used to anatomically complete missing tooth parts with porcelain.

 Composite inlay onlay fillings:

Since the composite fillings prepared in clinics for back teeth have greatly developed, inlay-onlay composite fillings are not superior to them anymore and therefore not much preferred.

aesthetic teeth fillings: Fields of Application

 Molar teeth with extreme material loss and/or one or two fractures

 Molar teeth with problems of interface decay on both sides

 Molar teeth with excessively thin tissues and more fragility due to root canal therapy

 Back teeth in general

Aesthetic Teeth Treatment

Session One:

 The tooth is cleared off all decayed areas including dry rot areas.

 Correction of lines that may hinder reliable measurement of “concave/undercut” areas and preparation of the porcelain bit by using suitable filling materials.

 Precise measurement of the tooth to be crowned with porcelain and delivery of the data to the laboratory

 Temporary loading of the roots with a suitable filling material


Session Two:

 Rehearsal of the porcelain onlay-inlay bit that anatomically copies the missing tissue of the tooth

 The porcelain filling parts must be in complete compliance with the tooth. If no problems are observed, the porcelain bit is pasted to and integrated with the tooth by using an adhesive system during the same session.

 The treatment is complete.


Aesthetic teeth fillings: Duration

The treatment is complete in two sessions and the second session takes place 1-3 days after the first one.

If there is a problem with the measurements or preparation of the tooth and if it has become necessary to take the measurements again, a third session may be required.


Advantages of aesthetic teeth fillings

Far more durable than composite fillings and there are scarcely any edge leaks observed.

With inlay-onlay fillings, crowns that require abrasion of healthy tissues are no more necessary.

This is a restoration system that preserves its aesthetic properties and durability for long years.

Mastication interfaces and interface surfaces of porcelain fillings are perfectly polished and therefore prevent bacterial growth and spotting.

Because they are prepared in a laboratory environment, porcelain fillings can almost perfectly copy the anatomy of missing contours and contact points of a tooth. Therefore, accumulation of food residues between teeth or such other problems are out of the question.

Because the mastication surfaces of porcelain fillings are prepared in a way to shadow-copy the anatomic mastication line of the tooth, the mastication and grinding functions of porcelain fillings are far superior to composite ones.

Since porcelain fillings can establish smooth and stress-free contact with the tooth, they also prevent cracks and fractures that may occur in weaker parts of the tooth.

Disadvantages of Aesthetic Inlay Onlay Filling

The most significant disadvantage of this system is that it is more expensive than other composite aesthetic fillings. The cost of porcelain inlay onlay fillings is almost 3-4 times the cost of aesthetic composite fillings.

Whereas all other composite restorations can be completed in one single session, inlay onlay fillings require more time (although it is now possible to complete the treatment in one single session with certain cad-cam system devices used in some clinics) and often go on for at least two or three sessions depending on laboratory works.

Porcelain inlay-onlay fillings require more precision compared to aesthetic composite fillings.

If the work is not precise enough or if there is not a 100%-match, the results are often disappointing.


Inlay and onlay fillings can also be prepared in computer environment according to the 3D image of the mouth taken with special oral scanners.

For this practise, a clinic needs to have a scanning system, also called cad-cam. With certain cad-cam systems, it is also possible to finish inlay onlay fillings in one single day.


Success factors on aesthetic teeth fillings

Expectations of the patient should be learned to the slightest detail.

Measurements require technical precision and should be taken carefully at all stages.

Long-term success of treatment depends on careful mouth care and hygiene.

The patient should visit a dentist regularly, at least once every year.
