title: Treatment outcome of dental implants in the esthetic zone: a 12- to 15-year retrospective study.
abstract: In the mid-nineties, 27 patients received 31 implant-supported crowns in the anterior maxillary region, and 12 to 15 years later, 18 patients (67%) with 22 implants (67%) participated in a retrospective study evaluating implant survival, bone loss, prosthetic complications, patient satisfaction, and patient and professional evaluation of esthetics. One implant was lost because of implant fracture after 10 years. Mean marginal bone loss was 1.53 mm (standard error ± 0.17 mm). In 6 patients, 6 crowns were replaced and 1 repaired. In 3 patients, 3 crowns had minor unrepaired porcelain fractures. Implant survival was 95.5%, and, despite the high frequency of prosthetic complications, patients were generally very satisfied with the long-term treatment outcome.
