The etched cast restoration--clinical techniques and long-term results.

The etched cast restoration was introduced as the "Maryland bridge" in 1980. The technique has continued to evolve with modifications in tooth structure and framework design as well as improvements in luting resins, including some that chemically bond to the alloy. The conservation of tooth structure and the avoidance of involving the gingival crevice remain the major advantages of the technique. Research has shown that the etched cast restoration, when designed with a retentive framework, exhibits bond strengths comparable with those of traditional complete coverage restorations. The main purpose for this retentive framework is to limit the stresses placed on the resin, thus preventing the phenomenon of stress fatigue in the resin. Clinical observations and an 11-year clinical study involving 127 restorations confirm this research. The long-term success rate in this study was 92.9%.

Aesthetic partial-coverage dental restorations.

The literature on the subject of aesthetic partial-coverage restorations, including laminate veneers, laminate veneer bridges, composite-resin and ceramic inlays and onlays, computer-designed restorations, and etched cast restorations, has continued to expand into the 1990s. Investigations regarding fit, longevity, wear, and microleakage, as well as descriptions of clinical techniques, were well documented world-wide in 1991. The purpose of this review is to discuss some of the more important papers published during the past year.

Recent advances in etched cast restorations.

This article described the etched cast restoration. The advantages, disadvantages, indications, contraindications, and technique were discussed. The rationale for modifications in the original framework design and tooth preparation was also presented; some unique advantages over traditional fixed prosthodontics are provided. A retentive framework with maximum coverage is recommended until research expands and simplifies the technique.

A long-term prospective study of the etched-cast restoration.

The etched-cast restoration was introduced in 1980, and a prospective study was initiated in March 1981 to determine if resin-bonded prostheses would prove to be a long-term alternative to traditional complete and partial coverage restorations. All resin-bonded restorations placed since that time in the author's private prosthodontic practice have been recorded in the study. The success rate of 127 restorations has been 92.9%, with a mean longevity of 5 years and 8 months.
