Microleakage of oral microflora for porcelain and some porcelain repair materials--in vitro study.

Abstract

Repairing porcelain fractures has become of interest to the dentist. The intra oral fracture of metal-ceramic restorations may be due to inadequate metal support, excessive porcelain thickness, technical flaws, and occlusal forces. Various techniques for intra oral porcelain repair have been suggested. The resin-porcelain junction has been in question since the advent of the porcelain veneer for cast metal restorations. To enhance this, several intermediary products and techniques have been developed to increase the chemical bond between the fractured porcelain and the repair materials. Clinical procedures for porcelain repair has required roughening of porcelain surface with a rotary abrasives, application of silane followed by composite to replace the contour of the restoration (2, 13, 14). Laboratory data suggested that the strong bond of the repair materials was developed.
