【 摘 要 】

INTRODUCTION: Introduction The purpose of this study was to assess the impact of molecular precision implant-abutment design on the maintenance of crestal bone levels around dental implants and the cumulative survival and success rates for the different types of implant-abutment designs. METHODS: In this retrospective study, two groups of titanium alloy implants with sandblasted and acid etched (SLA) surfaces were included: (a) a new concept-platform switching and concave abutment design group provided by new generation precision molecular dental implants (n=51) and (b) conical anatomical abutment design group (n=51). All clinical and radiologic data of forty five patients who meet the the eligibility criteria were assessed for the present study. Measurements of marginal bone loss around the dental implants was performed on the standardized digital panoramic radiographs immediately after implant placement and at a mean follow-up of 37 months after loading. Implant clinical success was evaluated with Kaplan Meier survival algorithm.RESULTS: Implant abutment design had a statistically significant effect on marginal bone loss when compared two equal (n=51) groups (p≤ 0.05). The average marginal bone loss was 0.44 +- 0.33 mm in the conical anatomical abutment design group and 0.34 +- 0.32 mm in the platform switching and concave abutment design group. The rates of cumulative survival and success of implants were 98% in both groups.DISCUSSION AND CONCLUSION: Platform switching and concave abutment profile reduced marginal bone loss compared with the conical anatomic abutment design. The new generation implant abutment design is of additional benefit in preserving marginal alveolar bone.
