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 کاملInfluence of marginal fit and cement types on microleakage of all-ceramic crown systems.
The purpose of this study was to evaluate the effects of both marginal fit and cementing with different luting agents on the microleakage of all-ceramic crown systems. Thirty-six extracted upper central incisors were prepared for full-coverage crowns and were divided into three groups. Group 1: CAD/CAM-fabricated ZrO2, Group 2: Heat-pressed lithium-disilicate, and Group 3: Cast Cr-Co copings as...
متن کاملComparing Marginal Fit and Marginal Gap between Sholder Bevel and 135° Finish Line Designs in Posterior Metal Ceramic Restoration Crowns
Background and purpose: One of the major challenges for dentists is providing the patients with a crown of appropriate marginal fit and marginal gap. Preparation of a 135° finish line has some advantages such as technical ease and appropriate finish line record. Nevertheless, few studies investigated this type of finish line. The current study aimed at comparing marginal fit and marginal gap in...
متن کاملComparison of Marginal Fit between Collarless Metal Ceramic and two all Ceramic Restorations
Marginal adaptation of the crown is a crucial factor in determining its clinical acceptability. Crown fit as judged by marginal seal influences the longevity of the cast restorations to a great extent. Metal ceramic restorations have been implicated for the discoloration in area of labio-gingival margin. Attempts to rectify this, by altering the design of metal frame works as eliminating the la...
متن کاملComparison between deep chamfer and 135 ̊ tooth preparation designs on marginal fit and marginal gap in posterior metal-ceramic crowns
Background and Aims: One of the most important challenges for dentists is providing a crown with appropriate marginal fit and gap. The 135-degree tooth preparation found to have some advantages such as technical ease and appropriate finish line record. Despite the advantages of 135-degree tooth preparation, scant research has been done in this area. Therefore, the aim of this study was to compa...
