The inlays, onlays and overlays are in fact fillings prepared by the technician in his laboratory based on an imprint of the patient’s tooth. This will be bonded afterwards into the previously prepared cavity. We recommend using these especially for changing big amalgam fillings, as well as rebuilding teeth that are destroyed beyond repair with normal fillings but not yet in need of full crowns. Using overlays we protect the thinned cusps and walls of the tooth, thus protecting them from cracks and ultimately from breaking. The dental inlays made by Belle-Glass are a mix of ceramic and composite, benefiting from both components, gaining the strength of the ceramic and the elasticity of the composite. E.max ceramic inlays are also available for areas where high resistance is needed, and high colour-stability.
