Immediate implant placement and provisionalisation in the aesthetic zone.

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 at Tfollow-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.
