Internal Defects in All-ceramic Crowns Using Computed Tomography
also often required even in the posterior region. However, all-ceramic crowns pose some problems, including weak mechanieal properties and occurrence of cracks or pores in the erown that could ultimately lead to fracture oi' the restorationii'. Thus far, all-ceramic crowns have been fabricated by firing porcelain manuaNy onto a refractory die, or by casting or heat-pressing the cerarnics. Howev...
متن کاملApplication of All Ceramic Materials in Dentistry
The daily increase in Patientschr('39') demand for cosmetic treatments has led to dental restorations moving towards the use of all-ceramic materials. The development of all-ceramic restorations over the last decade has revolutionized aesthetic dentistry. Recent advances in ceramic manufacturing and processing methods have led to the evolutionary growth of all-ceramic materials with superior bi...
متن کاملSimulation of clinical fractures for three different all-ceramic crowns
Comparison of fracture strength and fracture modes of different all-ceramic crown systems is not straightforward. Established methods for reliable testing of all-ceramic crowns are not currently available. Published in-vitro tests rarely simulate clinical failure modes and are therefore unsuited to distinguish between the materials. The in-vivo trials usually lack assessment of failure modes. F...
متن کاملToughening of CAD/CAM all-ceramic crowns by staining slurry.
The ability of staining slurries containing silver and/or potassium compounds to enhance the mechanical properties of a leucite-reinforced glass ceramic (IPS Empress CAD) was investigated by measuring the Vickers hardness, median crack length, toughness, and compressive residual stress of specimens. A staining slurry containing potassium ions was found to increase the toughness of IPS specimens...
متن کاملClinical marginal and internal gaps of zirconia all-ceramic crowns.
PURPOSE Marginal and internal gaps of NobelProcera crown zirconia were clinically evaluated using silicone materials. MATERIALS AND METHODS Ninety-one crowns were examined before final cementation, and white and black silicone materials were used to record the marginal and internal fit. The silicone materials were sectioned bucco-lingually and mesio-distally, and the thickness of the silicone...
