Repair of metal-ceramic restorations using an abrasive silica-impregnating technique: two case reports.
The loss or fracture of porcelain from a crown or bridge may be viewed by patients as a dental problem in need of urgent repair. Resin-based and silica coating materials are available that demonstrate good bond strengths to metal and porcelain in the laboratory. This paper describes two cases in which a recently introduced silica coating system was used for repairing fractured metal-ceramic restorations. However, no long-term studies on the success of these materials in repairing fractured porcelain are available.
