title: Evaluation of peri-implant soft tissue and bone levels around early loaded implant in restoring single missing tooth: A clinico-radiographic study.
abstract: BACKGROUND
  One-stage nonsubmerged protocol which can achieve success rates comparable to implants placed in a two-staged submerged procedure also the preconditions for periimplant bone regeneration has lead to more refined concepts of implant loading.
  
  
  METHODS
  Twenty sites with single missing tooth were included in this study. Clinical parameters included sulcus bleeding index (sBI), probing pocket depth (PD), and papilla index (PI) and radiographic parameters included crestal bone level were assessed for a period of 9 months.
  
  
  RESULTS
  The crestal bone loss showed mean value ranging from baseline 0.25 ± 0.11 to 0.31 ± 0.08 at 3 weeks, to 0.67 ± 0.13 at 3 months, to 0.85 ± 0.09 at 6 months, and to 0.88 ± 0.12 at 9 months. Probing PD, the mean value for probing PD at 3 weeks 1.20 ± 0.83, 3 months 1.60 ± 1.1, at 6 months 1.40 ± 1.14, and at 9 months 1.20 ± 1.0. sBI, mean value for sBI at 3 weeks 0.00 ± 0.00, 3 months 0.3 ± 0.11, at 6 months 0.09 ± 0.25, and at 9 months 0.08 ± 0.24. PI, showed a significant difference among at different points of time with P = 0.000.
  
  
  CONCLUSIONS
  The dental implants showed <1 mm of crestal bone loss at 9 months follow-up, clinically significant marginal bone loss occurred between the time of implant placement and 3 months. Subsequent to that, bone loss observed around the implant up to 9 months was minimal. The periimplant soft tissue maturity was maintained throughout the study.
