title: Immediate Dental Implant Placement in Sockets Augmented With HTR Synthetic Bone.
abstract: OBJECTIVE
  The purpose of this article is to present the results of using immediate implant placement in combination with HTR synthetic bone socket grafting to achieve a predictable restorative result.
  
  
  METHODS
  Twenty-three hydroxylapatite-coated cylinder implants (Spline, CenterPulse Dental, Carlsbad, CA) were placed into fresh extraction sockets in 19 patients. In each case, HTR synthetic bone (Bioplant, Inc., South Norwalk, CT) was used to fill any voids remaining in the sockets and to augment the facial aspect of the ridge. The restorative phase was initiated approximately 6 months after implant placement. Conventional impression techniques were used and porcelain-fused-to-metal crowns were selected as the final restorations.
  
  
  RESULTS
  The prosthetic outcome was evaluated as generally favorable. Only 4 (17%) of the dental implants required an angled abutment. The gingival contour was excellent in 61% and good in 35% of the cases. The emergence profile was evaluated as class I (full papilla) in 37% and class II, III, and IV in 21% each.
  
  
  CONCLUSIONS
  The clinical results of this study demonstrate that immediate implant placement in combination with HTR synthetic bone grafting of residual socket voids and crestal deformities is a predictable procedure and provides a good base for successful prosthetic reconstruction. Adequate gingival contour and favorable emergence profile can be expected when combining immediate implant placement and HTR grafting material.
