Ceramic Laminate Veneers: Materials Advances and Selection
Porcelain laminate veneers have been a common treatment strategy in dental clinics. It is a conservative method for treatment of esthetic and functional problems in anterior region of oral cavity. Wide range of dental ceramics is now available on market for fabrication of laminate veneers. Clinician should have enough knowledge regarding the composition and properties of these materials in orde...
متن کاملEvaluation of contemporary ceramic materials.
The last 25 years have witnessed the introduction of a bewildering number of ceramic systems to the dental profession. Most of these systems have been introduced with little or no clinical testing. Laboratory studies of physical and mechanical properties of ceramics provide little predictive information regarding likely clinical survival rates. Early adopters of many of these new systems learne...
متن کاملIn vitro evaluation of the fracture strength of all-ceramic core materials on zirconium posts
OBJECTIVE For most endodontically treated teeth, tooth-colored post-core systems are preferable for esthetic reasons. Therefore, improvements in material strength must also consider tooth colored post-core complexes. The objective of this study was to evaluate the difference in tooth colored post-core complex strengths. MATERIALS AND METHODS A total of 33 human maxillary central incisor teeth...
متن کاملIn vitro evaluation of fracture strength of zirconia restoration veneered with various ceramic materials
PURPOSE Fracture of the veneering material of zirconia restorations frequently occurs in clinical situations. The purpose of this in vitro study was to compare the fracture strengths of zirconia crowns veneered with various ceramic materials by various techniques. MATERIALS AND METHODS A 1.2 mm, 360° chamfer preparation and occlusal reduction of 2 mm were performed on a first mandibular molar...
متن کاملMechanical properties of commercial high strength ceramic core materials.
OBJECTIVE The objective of the present study is to evaluate and compare the flexural strength, dynamic elastic moduli and true hardness (H(o)) values of commercial Vita In-Ceram alumina core and Vita In-Ceram matrix glass with the standard aluminous porcelain (Hi-Ceram and Vitadur), Vitadur N and Dicor glass and glass-ceramic. METHODS The flexural strength was evaluated (n=5) using 3-point lo...
