title: Soft and hard tissue assessment of immediate implant placement: a case series.
abstract: OBJECTIVE
  The aim of this prospective study was to evaluate clinically and radiographically the success and esthetic result of immediate implant placement at the time of extraction.
  
  
  METHODS
  Twelve patients with 14 titanium screw-shaped implants (13-16 mm length and 4.3 or 5 mm diameters) were placed in the extraction sockets. Defects after implant placement were recorded, and then filled up with deproteinized bovine bone mineral, bioabsorbable collagen membrane, and absorbable pins. The defect was again re-evaluated at second-stage surgery. Clinical and radiographic parameters of the peri-implant conditions were assessed at the moment of prosthesis placement and at 1-year follow-up.
  
  
  RESULTS
  The cumulative implant survival and success rate was 100% after a 1-year observation period. Analysis of the esthetic result showed that the mean pink esthetic score (PES) was 11.1 (SD 1.35) at 1-year follow-up. At 1 year, 64.3% papillae had a score of 2 and the remaining 35.7% score 3 according to the Jemt (1997) papillary index. Optimal value of width of the keratinized mucosa was recorded in 13 (92.9%) implant cases in both periods of follow-up. At 1-year follow-up, the linear distance between implant-shoulder to the bone peaks remains stable with a mean of 2.62+/-0.2 mm at the mesial and 2.9+/-0.58 mm at the distal aspect.
  
  
  CONCLUSIONS
  Careful evaluation of potential extraction sites before immediate implant installation promotes optimal implant esthetics.
