Context: There is limited evidence on the outcome of single-piece implant-prosthetic complex after immediate nonfunctional loading in varied bone densities. Aim: The aim of this study was to report the outcome of single-piece implant-prosthetic complex with a novel cervical platform design in the anterior and posterior jaws 3 years after loading. Setting and Design: Prospective clinical study. Materials and Methods: The present study included placement of 90 single-piece implants in the anterior and the posterior jaws in varied bone densities. After immediate loading, survival and marginal bone loss was recorded at regular intervals. Statistical Analysis: Independent sample t-test and paired t-test were done (P = 0.05). Results: Group I, annual marginal bone loss at the end of one, 2 and 3 years was 0.21, respectively, in both bone densities. Group II, annual marginal bone loss in D2 regions was 0.75,0.38 and 0.18; 0.64, 0.28 and 0.18 in D3 regions at the end of 1, 2, and 3 years, respectively. Group I showed no statistically significant difference in marginal bone loss between D2 and D3 bone annually in contrast to Group II. Intragroup comparisons of mean between baseline and various time intervals showed statistically significant bone loss in both bone densities. Conclusion: Three years after loading, single-piece implants with the novel cervical platform design provided survival rates of 93% in the maxillary anteriors and 91% in the mandibular posteriors. D3 bone showed more marginal bone loss than D2 bone.
