Abstract

CAD-CAM sistemlerinde üretilen tam seramik ve seramik benzeri malzemeler yapılan sınıflandırma sistemine göre; cam maktriks seramikler, polikristalin seramikler ve rezin matriks seramikler olarak üç gruba ayrılmaktadır. Geliştirilen yeni seramik materyallerden monolitik olarak tasarlanıp üretilen restorasyonlar, yüksek dayanıklılığa sahip bir altyapı tarafından desteklenip ışık geçirgenliği fazla olan bir seramikle veneerlenen tabakalı restorasyonlara göre önemli avantajlara sahiptir. Geleneksel olarak veneerlenen veya hasta başında tek seansta üretilen monolitik tam seramik restorasyonlarda, restorasyonun üretimi sonrasında simantasyona hazır düzgün bir yüzey oluşmamaktadır. Bu nedenle restorasyonlar, hastaya teslim edilmeden önce mekanik olarak parlatılmalı veya glaze işlemi uygulanmalıdır. Glaze veya mekanik polisaj ile bitirme işlemleri, restorasyonların üretimi sonrasında meydana gelen yüzey pürüzlülüğünü azaltmak ve optik özellikleri geliştirmek için kullanılabilmektedir. Kullanılan seramik türüne ve üretim yöntemine göre yüzey bitirme işlemleri değişmektedir. Bu literatür derlemesinin amacı, CAD-CAM sisteminde üretilen monolitik seramik restorasyonlarda uygulanan yüzey bitirme işlemleriyle ilgili güncel bilgileri ve konu ile ilgili yapılan çalışmaları sunmaktır.

Surface finishing procedures of CAD-CAM produced monolithic ceramic restorations

Abstract

CAD-CAM produced all ceramic and ceramic-like materials are classified as glassy matrix ceramics, polycrystalline ceramics, and resin matrix ceramics. Monolithic restorations which are designed and manufactured from newly developed ceramic materials have some advantages compared to conventionally veneered restorations. Neither conventionally veneered nor monolithic ceramic restorations do not have smooth restotation surfaces which is ready to cementation after the production procedure. Therefore, ceramic restorations should be mechanically polished or glazed before cementation. Thus, surface finishing procedures are necessary. Finishing the ceramic surface with glazing or mechanical polishing are used to reduce surface roughness and improve optical properties of the ceramic materials. Surface finishing procedures differ according to both ceramic type and ceramic production method. The aim of this review is to present current information and related studies on surface finishing procedures of CAD-CAM produced monolithic ceramic restorations.
