The aim of this retrospective study was to assess the outcome of immediate single-tooth implant placement and provisionalisation in the aesthetic zone regarding hard and soft peri-implant tissue parameters and patient-related outcome measures in a private practice. All consecutively treated patients with single-tooth immediate implant placement and provisionalisation between the period 1 January 2006 and 1 April 2013 in a referral practice in Amsterdam, the Netherlands, were included in the study. Fifty-one patients of a total of 64 could be examined at follow-up (Tfollow-up). Radiographs were present from implant placement (Tplacement), after definitive crown placement (Tdefinitive), and new radiographs were taken at the follow-up appointment (Tfollow-up). Next to this, soft tissue parameters, patients’ satisfaction and professionals’ aesthetic scores were measured atTfollow-up. Implant survival was 96·9% after a mean follow-up period of 4 years following implant placement. At definitive crown placement, mean marginal bone-level loss was 0·25 mm (SD 0·19). Mean marginal bone-level loss following definitive crown placement was 0·06 mm (SD 0·10) (Tdefinitive to Tfollow-up) after a mean follow-up period of 4 years. Plaque index, bleeding index and gingival index scores were low. Patients’ satisfaction was rated very high: 9·0 (SD 0·7). Professionals aesthetic score was 16·49 (SD 1·86). From this study can be concluded that immediate placement of implants followed by immediate provisionalisation resulted in a high survival rate, minimum peri-implant bone loss, very good aesthetics and satisfied patients after a mean follow-up period of 4 years.
