Repairing porcelain restorations intraorally: techniques and materials.

Ceramic and metal-ceramic restorations have the potential to fracture. Repairing porcelain restorations has become a serious cosmetic and clinical problem. By using porcelain-repair systems, porcelain fractures can be predictably fixed without removal of a prosthesis. The newest porcelain-repair systems show excellent durability of adhesion as well as bond strength. This article presents an overview of the techniques and materials and compares the four most-popular intraoral porcelain-repair systems.

Microleakage reduction using glass-ceramic inserts.

Thirty human non-carious specimens were used in this in vitro study. The specimens were divided into three groups of 10 each: Group 1: incremental fill: Group 2: Beta-Quartz glass-ceramic inserts: Group 3: pre-cured resin composite inserts. All restorations were placed with TPH resin composite. The specimens were thermocycled and sectioned. Microleakage was determined on a scale of 0 (no microleakage) to 5 (microleakage extending to the axial wall). Results of the study indicated that Beta-Quartz glass-ceramic inserts and incrementally placed resin composite restorations exhibited significantly less microleakage compared to pre-cured resin composite inserts (P < .03, Chi-Square Test).
