Comparative 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 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 کاملAccuracy evaluation of metal copings fabricated by computer-aided milling and direct metal laser sintering systems
PURPOSE To assess the marginal and internal gaps of the copings fabricated by computer-aided milling and direct metal laser sintering (DMLS) systems in comparison to casting method. MATERIALS AND METHODS Ten metal copings were fabricated by casting, computer-aided milling, and DMLS. Seven mesiodistal and labiolingual positions were then measured, and each of these were divided into the catego...
متن کاملThe influence of framework design on internal and marginal gap width of anatomic and nonanatomic metal copings fabricated by selective laser sintering
In spite the fact that conventional slip-cast crowns are still largely used in everyday practice, and these techniques had shown their efficiency, selective laser sintering is a new technology which arouse more and more interest in prosthetic dentistry. One of the key factor which determines clinical success is the marginal and internal fit of fixed dental prostheses who influences the long-ter...
متن کاملMarginal Accuracy and Internal Fit of 3-D Printing Laser-Sintered Co-Cr Alloy Copings
Laser sintered technology has been introduced for clinical use and can be utilized more widely, accompanied by the digitalization of dentistry and the development of direct oral scanning devices. This study was performed with the aim of comparing the marginal accuracy and internal fit of Co-Cr alloy copings fabricated by casting, CAD/CAM (Computer-aided design/Computer-assisted manufacture) mil...
