Aesthetic inlay/onlay fillings can be made of composite material or dental ceramics. These are dental fillings (seals) created in a laboratory.
The Procedure - We start out, as with plain filling, by removing the caries and the inlay/onlay tooth preparation. As soon as the tooth is prepared, its print is taken and sent to the laboratory where the inlay/onlay filling is created.
On the next visit, temporary filling is removed and completed inlay/onlay is cemented with special adhesive cement into the tooth. An inspection of the contact with other teeth is carried out and fine polishing of the teeth is performed..
The advantage of inlay/onlay filling in comparison to classical aesthetic fillings is that they are longer lasting and can be aesthetically made perfect in a laboratory. Classical aesthetic fillings, performed directly in the oral cavity are contacted (squeezed) during polymerization (hardening) which leads to micro-fissures on the seal between the fillings which reduces its durability.
In the process of creating an inlay/onlay filling in the laboratory, there are no contractions. Even if it happens, theoretically, it is compensated by inlay/onlay cementing into the tooth which seals all fissures between the fillings and the teeth, same way as in applying the ceramic crown. This makes the inlay/onlay fillings much more durable than the classic fillings performed directly in the oral cavity.
