CURRENT DESIGN AND MANUFACTURING TECHNIQUES USED IN FIXED PROSTHETIC RESTORATIONS

Abstract

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 filesplitting 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

SABİT PROTETİK RESTORASYONLARDA KULLANILAN GÜNCEL TASARIM VE ÜRETİM YÖNTEMLERİ

Abstract

Özellikle posterior bölgede uygulanan sabit protetik restorasyonlarda, çiğneme kuvvetleri karşısın- da restorasyonun dayanıklılığını arttırmak amacıyla üst yapı seramiği alt yapı ile desteklenmelidir. Gelişen teknoloji ve kullanılan materyallerdeki yenilikler ile, bilgisayar destekli tasarım/bilgisayar destekli üretim sistemleri günümüz protetik restorasyonlarda alt yapıların yanı sıra üst yapıların hazırlanmasında da kullanılmaktadır. Sabit protetik restorasyonlarda sıklıkla kullanılan alt yapı hazırlama yöntemleri gele- neksel kayıp mum tekniği, eksiltme ve tabakalama esaslı ekleme yöntemleri iken; üst yapı hazırlama yön- temleri tabakalama, ısı-basınç ile şekillendirme ve bilgisayar destekli tasarım/bilgisayar destekli üretim sistemi ile elde edilen ‘’dosya bölme’’ teknikleridir. Bu derlemede, sabit protetik restorasyonlarda kullanılan güncel alt yapı ve üst yapı hazırlama yöntemleri incelenmektedir.
