One-year clinical evaluation of an anterior composite resin.

An anterior composite resin was evaluated in a clinical study of 93 Class III and Class IV restorations placed in patients aged 12 to 50 years. The restorations were evaluated at baseline, 6 months, and 1 year. Sixty-four (79%) of the 81 restorations examined at the 1-year recall were unchanged.

Esthetic repair of porcelain in a complete-mouth reconstruction: a case report.

This paper presents a relatively simple method of repairing a large porcelain fracture in a porcelain-fused-to-metal crown that is part of a multi-unit fixed partial denture. The technique involves fitting a "modified" porcelain-fused-to-metal crown over the original damaged crown following some preparation of the original crown. This technique is of special value when a permanently cemented multi-unit restoration is involved, eliminating the need to replace the entire restoration and providing a durable esthetic result.
