Extensive tissue loss can occur in some teeth due to decay or trauma. In cases of extensive tissue loss, commonly seen in teeth with root canal treatment, direct composite fillings applied in the mouth may not meet expectations in terms of aesthetics, function, and durability. In such situations, onlay-inlay restorations are preferred. The distinction between onlay and inlay restorations depends on the extent and boundaries of the tissue loss.
All previous restorations, decayed tissues, and other elements are removed from the planned tooth. The preparation is completed without causing additional tissue loss. The intraoral condition is transferred to the laboratory using 3D scanner systems, and a restoration is prepared with special materials to complement the existing tooth structure.
The prepared tooth surface is protected with temporary filling materials between sessions. Once the restoration is completed in the laboratory, its compatibility with the tooth surface is checked. After ensuring proper fit, the restoration is adhered to the tooth surface using special adhesives.
