N2 - Aim: The main objective of this clinical study was to document midfacial soft tissue dynamics following single immediate implant treatment (IIT) and conventional implant treatment (CIT) in the anterior maxilla when performed by experienced clinicians in well-selected patients. Material and Methods: Appropriate bone volume and ideal soft tissue levels were considered requirements for implant therapy. Additional prerequisites for IIT were intact socket walls and a thick gingival biotype. CIT included standard flap elevation whereas IIT was either performed with a flap or flapless procedure. All implants were provisionally restored using cemented acrylic crowns. Bone levels, papillae and midfacial soft tissue levels were monitored at regular intervals. The aesthetic outcome was assessed after 1 year using the pink aesthetic score (PES) and white aesthetic score (WES). Results: Sixteen patients (10 men, six women; mean age 45) received an immediate implant and 23 patients (12 men, 11 women; mean age 40) had conventional implant surgery. One immediate implant failed in the early healing phase. The mean bone level from the implant-abutment interface was 0.85mm for IIT and 0.65mm for CIT after 1 year (p=0.144). Mesial papillae remained stable over time. Minute loss of distal papillae occurred following IIT (-0.38 mm) and a tendency for re-growth was found following CIT (0.60 mm). Midfacial soft tissues remained stable over time following IIT with only 7% showing advanced recession (>1 mm). Flapless surgery induced less midfacial recession than flap surgery (p=0.023). Significant midfacial recession occurred following CIT (-1 mm). Overall, 24% were aesthetic failures (PES<8 and/or WES<6) and 8% showed an (almost) perfect outcome (PES≥12 and WES≥9). The remainder (68%) demonstrated acceptable aesthetics. Conclusions: Immediate implants demonstrated fairly stable midfacial soft tissue levels with only a minority of cases showing advanced recession. Irrespective of the timing of implant placement, aesthetic failures seem to be rather common and only a strict minority may show perfection. © 2011 John Wiley & Sons A/S.
