| Abstract | ||
| Objectives: This study was conducted to compare the early radiographic bone level changes around delayed single implants in the posterior maxilla with different beveled smooth collar heights. Materials and Methods: Thirteen patients with a missing posterior tooth in the maxilla were randomly allocated to be treated with an implant with either a beveled 1.5 mm smooth collar or a beveled 0.3mm smooth collar. Implants were installed in healed sites and were loaded after 4 months. Follow-up visits were conducted 4 and 10 months after implant placement. Results: Assessment of marginal bone levels showed Non-Significant (P-value = 0.05) differences in mesial and distal marginal bone level mean values between both groups within each follow-up period. Assessment of marginal bone loss showed Non-Significant (P-value = 0.05) differences in mesial and distal marginal bone loss mean values between both groups within each time interval. Conclusion: For posterior tooth replacements, implants with different smooth collar heights showed similar and favorable radiographic outcomes with acceptable marginal bone loss after 6 months of loading. | ||
