Share Abstract:

A retrospective evaluation of a series of dentin-bonded ceramic crowns

Burke/Qualtrough/Wilson

Pages: 103-106
PMID: 9643243

Objective: This study assessed the clinical performance of dentin-bonded crowns, in which ceramic crowns are bonded to underlying dentin with a resin composite-based luting mater ial and a dentin bonding agent. Method and materials: Twenty-five patients who had received such restorations more than 1 year previously were recalled for evaluation of their crowns. Results: Sixty dentin-bonded complete-coverage restorations were assessed. Forty-one of the crowns had been placed on incisor teeth. The mean time since placement of the restoration was 2.43 years. Fifty-seven of the 60 restorations were intact. The three failures had resulted fromcracks in the restorations, which had not clinically debonded. No secondary caries was detected at the crown margins, and anatomic form was assessed as excellent for 56 crowns. Root canal treatment had been required in one case. Color match was rated very good for 47 crowns. All 25 patients were satisfied with their restorations. Conclusion: Dentin-bonded crowns may be found to have a low rate of failure and to provide a high level of patient satisfaction.
