Materials and Methods: Five three-dimensional finite element models representing a
mandibular first molar tooth restored with crowns of gold, porcelain fused to metal …

Background and aim: One of the major problems of all ceramic restorations is their probable
fracture against the occlusal force. The aim of the present in vitro study is to compare the …

PURPOSE The aim of this study was to compare the precision of optical impression (Trios,
3Shape) versus that of conventional impression (Imprint IV, 3M-ESPE) with three different …

Objective One of the major problems of all ceramic restorations is their probable fracture
against the occlusal force. The aim of the present in-vitro study is was to compare the effect …

Objective The aim of this in vitro study was to investigate the effect of Shoulder versus
Chamfer margin design on the marginal adaptation of zirconia (Zr) copings. Materials and …

Purpose Occlusal reduction is considered a fundamental step for providing adequate and
uniform space for the ceramic prosthesis; however, a flat occlusal surface is usually found …

Materials and methods This in vitro study was carried out with single-blind experimental
technique. One stainless steel die with 50'chamfer finish line design (0.8 mm deep) was …

Cervical restoration of a premolar tooth is a challenging task as it involves structural
modification to ensure the functional integrity of the tooth. The lack of retention in the cervical …

Materials and methods The study sample consisted of 40 three-dimensional computer
models of restored lower first molars with full crowns (gold, nickel-chrome, lithium disilicate …

Aim: The aim of the present in vitro study is to compare the resistance to fracture under a
cyclic load applied to o chamfer-edged vs. shoulder-edged Procera® All Ceram cores …
