OBJECTIVES High-strength ceramics are required in dental posterior restorations in order to withstand the excessive tensile stresses that occur during mastication. The aim of this study was to investigate the fracture behavior and the fast-fracture mechanical strength of three veneer-framework composites (Empress 2/IPS Eris, TZP/Cercon S and Inceram-Zirconia/Vita VM7) for all-ceramic dental bri...

During clinical practice, when performing prosthetic rehabilitation with single crowns, improper reproduction of the dental contour by the dental laboratory is a common occurrence. Therefore, the present study evaluated the fidelity of the reproduction of the buccal contour in an upper left canine performed by three Dental Prosthesis Technicians (DPT) using the indirect laminate veneer techniqu...

re-establishing a patient’s lost dental esthetic appearance is one of the most important topics for contemporary dentistry. new treatment materials and methods have been coming on the scene, day by day, in order to achieve such an aim. most dentists prefer more conservative and aesthetic approaches, such as direct and indirect laminate veneer restorations, instead of full-ceramic crowns for ant...

KEY CLINICAL MESSAGE This report describes the use of lithium disilicate glass-ceramic veneer-fixed dental prostheses in replacing congenitally missing maxillary lateral incisors. This kind of prosthesis has an advantage over a lingual-retainer resin-bonded fixed dental prosthesis in its capability of changing the color and shape of the abutment teeth. The prostheses provided an acceptable esth...

statement of the problem: porcelain laminate veneer is an esthetic restoration used as an alternative to full veneer crowns and requires minimal tooth preparation. in restoration with porcelain laminate veneers, both the longevity of the laminate and conservation of the sound tooth structure are imperative. purpose: the present study aimed to investigate the shear bond strength of porcelain lam...

Macrodontia is a rare but cosmetically challenging dental anomaly. The following case report is described of a young girl with macrodontia central incisors who was treated with direct composite veneer and gingival color composite. The aesthetic outcome was satisfactory without unnecessary loss of teeth.  

objective: zirconia cores have limited light transmittance and data are scarce on light transmission through zirconia cores with and without the veneering ceramic.   methods: in this in vitro study, disc-shaped specimens (11.5 mm in diameter and 0.4 (0.05) mm in thickness) were fabricated of three types of zirconia namely mamut, heany and zirkonzahn (n=5). a disc-shaped specimen (11.5 mm in dia...

AIM This study evaluated the effects of ceramic veneer thicknesses on the polymerization of two different resin cements. MATERIALS AND METHODS A total of 80 ceramic veneer disks were fabricated by using a pressable ceramic material (e.max Press; Ivoclar Vivadent) from a Low Translucency (LT) ingot (A1 shade). These disks were divided into light-cured (LC; NX3 Nexus LC; Kerr) and dual-cured (D...
