CURRENT DESIGN AND MANUFACTURING TECHNIQUES USED IN FIXED PROSTHETIC RESTORATIONS

Especially for the fixed prosthetic restorations in the posterior region, the veneering ceramic should be supported by the framework to increase the strength of the restoration against masticatory forces. by the improved technology and novelties in the used materials, computer aided design/computer aided manufacturing systems are used in the frameworks as well as in the veneering ceramics in contemporary prosthetic restorations. while the framework techniques frequently used in the fixed prosthetic restorations are lost-wax casting, subtractive and layered addivite techniques; methods used for the suprastructures are layering, pressing and the file- splitting technique obtained by computer aided design/computer aided manufacturing system. in this review, current framework and veneering techniques used in fixed prosthetic restorations are analyzed.
