Purpose: To evaluate gingival margin changes in the esthetic zone after immediate implant placement and provisionalization over 5 years with a custom anatomic provisional abutment.

Materials and methods: Single maxillary incisor immediate implant placement and provisionalization procedures, completed and followed between February 2006 and August 2006, were analyzed retrospectively. During clinical recalls at 3 months, 1 year, and 5 years, changes in gingival margins were recorded with clinical photographs and recorded in millimeters.

Results: Forty-seven patients each received a single implant (19 central incisors, 28 lateral incisors) and were followed for 5 years. Implants and restorations had a 100% survival rate during the study. The mean gingival margin changes (recession) were 0.17 mm at the time of definitive restoration, 0.27 mm at 3 months, 0.30 mm at 1 year, and 0.30 mm at...
