Marginal and Internal Crown Fit Evaluation of CAD/CAM versus Press-Laboratory All-Ceramic Crown
The aim of this article is to evaluate marginal and internal fit between the all-ceramic crowns manufactured by the conventional press-dental laboratory and CAD/CAM systems. Methods: Tooth #14 was prepared per standard specification to receive an all-ceramic crown restoration. Forty-five prep tooth #14 were duplicated and randomly divided into three groups (n=15). All-ceramic CAD/CAM system (Gr...
متن کاملEvaluation of internal fit of interim crown fabricated with CAD/CAM milling and 3D printing system
PURPOSE This study is to evaluate the internal fit of the crown manufactured by CAD/CAM milling method and 3D printing method. MATERIALS AND METHODS The master model was fabricated with stainless steel by using CNC machine and the work model was created from the vinyl-polysiloxane impression. After scanning the working model, the design software is used to design the crown. The saved STL file...
متن کاملEffect of cement space on the marginal fit of CAD-CAM-fabricated monolithic zirconia crowns.
STATEMENT OF PROBLEM Monolithic zirconia crowns fabricated with computer-aided design and computer-aided manufacturing (CAD-CAM) have recently become a common practice for the restoration of posterior teeth. The marginal fit of monolithic zirconia crowns may be affected by different cement space parameters set in the CAD software. Information is scarce regarding the effect of cement space on th...
متن کاملThe Effect of Preparation Design on the Marginal Integrity of Monolithic Zirconia Crown
Abstract Background & Aim: Marginal adaptation of full ceramic zirconia restorations are one of the important factors in their long-term success and one of the factors affecting marginal adaptation and their strength is the finish line design.This study was conducted to compare the effect of finishline design on the adaptation of monolithic zirconia crowns. Material and methods: In this in-vitr...
متن کاملEffect of sintering on the marginal and internal fit of CAD/CAM-fabricated zirconia frameworks.
The aim of this study was to investigate the effect of post-machining sintering on marginal and internal fit of CAD/CAM-fabricated zirconia frameworks. Single crown copings (A: abutment), three-unit bridge frameworks (APA, P: pontic), four-unit bridge frameworks (APPA), and five-unit bridge frameworks (A1P1A2P2A3) were fabricated with raw-stage zirconia blanks using a commercial CAD/CAM system ...
