This study evaluated the repair bond strength of a nanohybrid resin composite to a novel CAD/CAM hybrid ceramic based on four intraoral ceramic repair systems. Vita Enamic (VE) CAD/CAM hybrid ceramic was used in this study. Specimens were divided into five test groups according to the repair method performed on the ceramic surface: Gr C (No treatment; control); Gr CZ (Cimara Zircon); Gr PR (Por...

The repair of a fractured porcelain surface with a resin composite was investigated. The effects of applying an opaque resin to porcelain surfaces, which were silanated by a ceramic primer from a repair kit or by an experimental silane coupling agent, were studied. The porcelain surfaces were silanated for 10 sec and 60 min. Three types of adherents were evaluated: opaque resin with light irrad...

Aims: The aim of this study was to investigate the effect of flowable composite, as an intermediate layer between feldspathic porcelain and composite, on bond strength during intra-oral porcelain repair and its potential role in providing a long-lasting repair. Methods: Forty feldspathic porcelain (VMK 95) specimens were fired in metal ingots. They were airborne-particle abraded, etched with 4%...

Porcelain fused to metal restoration often fails in the form of adhesive fracture porcelain veneered layer. Intraoral repair can be used this type fracture. In intraoral repair, material is for bonding chemically oxide layer on surface. 10-MDP commonly dental practice. Another 6-MPHA because it a new that has C-P bond middle compound chemistry which more stable and withstand harsh chemical trea...

The authors’ intention was to present ceramic restoration repair as a reliable, low-cost and low-risk procedure, by demonstrating 3 cases in the aesthetic zone. Intraoral ceramic repair was chosen for the small porcelain fracture of the maxillary left central incisor and for the large porcelain surface detachment of the maxillary left lateral incisor, since patients did not want to replace the ...

Objective:This study investigated the cervicalmicroleakage between titanium and three porcelain systems. Material andMethods:The titanium used in this study (commercially pure, grade 2, IMNR Bucharest, Romania) was veneered with three porcelain systems specially designed for fusing on titanium: Ti22 (Noritake, Nishikamogun, Aichi, Japan), Triceram (Esprident, Ispringen, Germany) andVitatitanker...

The aim of this study was to compare the effects of different porcelain polishing techniques on the color change and surface roughness of feldspathic porcelains and lithium disilicate glass-ceramic system. 80 porcelain specimens were divided into two subgroups, each subgroup was divided into 4 groups of 10 specimens. Surfaces were polished with different ceramic polishers. VITA Easyshade spectr...

STATEMENT OF PROBLEM Production of a ceramic dental restoration that matches a target shade is dependent on porcelain thickness. Even when adequate porcelain thickness exists, clinical shade matches are difficult to achieve. PURPOSE This study predicted the thickness of dentin porcelain required to obtain a clinical shade match (</=3 DeltaE units) for a variety of dental porcelain systems and...
