Evaluation 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 کاملComparative evaluation of marginal and internal fit of anatomic and nonanatomic metal frameworks fabricated by selective laser sintering
For teeth restoring single metal-ceramic crowns were the gold-standard for many years. Selective laser sintering is a new technology which can provide accurate complex-shaped frameworks for dental restorations, layer-by-layer, according to a three-dimensional computer model, using metal powder. An important factor for long term success of fixed prostheses is the marginal and internal adaptation...
متن کاملMarginal 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 کاملComparison the Marginal and Internal Fit of Metal Copings Cast from Wax Patterns Fabricated by CAD/CAM and Conventional Wax up Techniques
STATEMENT OF PROBLEM Metal-ceramic crowns are most commonly used as the complete coverage restorations in clinical daily use. Disadvantages of conventional hand-made wax-patterns introduce some alternative ways by means of CAD/CAM technologies. PURPOSE This study compares the marginal and internal fit of copings cast from CAD/CAM and conventional fabricated wax-patterns. MATERIALS AND METHO...
متن کاملmarginal and internal fit of cad/cam and slip-cast made zirconia copings
background and aims. cad/cam systems facilitate the use of zirconia substructure materials for all-ceramic copings. this in vitro study investigated the marginal and internal fit of zirconia copings made with cad/cam system and slip-casting method. materials and methods. sixteen cad/cam made zirconia copings and 16 slip-cast made zirconia copings were fabricated and cemented with glass-ionomer ...
