Marginal and internal fit of zirconia copings obtained using different digital scanning methods.
The objective of this study was to evaluate the marginal and internal fit of zirconia copings obtained with different digital scanning methods. A human mandibular first molar was set in a typodont with its adjacent and antagonist teeth and prepared for an all-ceramic crown. Digital impressions were made using an intraoral scanner (3Shape). Polyvinyl siloxane impressions and Type IV gypsum model...
متن کاملEvaluation of marginal fit and internal adaptation of zirconia copings fabricated by two CAD - CAM systems: An in vitro study
STATEMENT OF PROBLEM Three main factors which determine the success of an All-ceramic restoration are esthetic value, resistance to fracture and third being the marginal fit. Marginal fit and internal adaptation are crucial factors in increasing the longevity of the restoration. Newer and economical CAD CAM systems have been introduced claiming better marginal fit and adaptation of All ceramic ...
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 کاملMarginal accuracy of computer-aided design- and computer-aided manufacturing-fabricated full-arch zirconia restoration
Objective This study evaluated marginal accuracy of full-arch zirconia restoration fabricated from two digital computer-aided design and computer-aided manufacturing (CAD-CAM) systems (Trios-3 and CS3500) in comparison to conventional cast metal restoration. Materials and methods A stainless steel model comprising two canine and two molar abutments was used as a master model for full-arch rec...
متن کاملبررسی تطابق کوپینگ‌های ساخته شده به دنبال استفاده از اسکنر داخل دهانی در دو ختم تراش زیر و حد لثه در سطوح مختلف دندانی
Background and Aims: Despite the increasing application of intra-oral scanners, the effect of finish line position on gingival margins adaptation is still discussed. The purpose of this clinical study was to evaluate the fitness of cobalt-chromium copings obtained from intraoral scanning in two depth of finish lines. Materials and Methods: Thirty teeth prepared for single premolar metal-cerami...
