Acid-etch retained cast metal prostheses: a seven-year retrospective study

The results of this study showed: retention rate was good, caries on the retainer teeth was almost nonexistent, and the supporting tissue clinically did not appear to have a greater incidence of periodontal problems. We believe that these results indicate that the cast acid-etch retained anterior prosthesis should be considered a permanent restoration and a valuable aid for the dental patient.
