METHOD FOR COMBINED DENTAL PROSTHESIS RESTORATION IN PARTIAL CERAMIC VENEER CHIPPING Russian patent published in 2014 - IPC A61C13/32 G01N3/08 

FIELD: medicine.

SUBSTANCE: material similar to the surface to be restored in colour is pre-selected. Working and auxiliary imprints are prepared. Cast models are made to be fixed in the articulator. A masticatory surface of the chipping is modelled in wax. Occlusion contacts are adjusted in an articulator. The masticatory surface modelled in wax is imprinted in transparent silicone. Chipping surfaces on the prosthesis are burred and etched. That is followed by applying silane to be polymerised. A composite is placed into a transparent mould. The mould is attached to the chipping surface and light-polymerised for complete radiographic inspection of the material through the transparent mould. That is followed by finishing the restored occlusion surface. Silane is selected taking into account its maximum bond strength to the restored ceramics.

EFFECT: by selecting the adhesion system having the optimum bond strength to the restored ceramics and adjusting the occlusion contacts in the articulator, the method enables providing the higher bond strength of the composite restoration to various ceramic types and ensuring more accurate restoration of the occlusion interactions with antagonist teeth.
