摘要：

PurposeThe optimal configuration of a customized implant abutment plays a crucial role in promoting bone remodeling and maintaining the peri-implant gingival contour. However, the biomechanical effects of abutment configuration on bone remodeling and peri-implant tissue remain unclear. This study aimed to evaluate the influence of abutment taper configurations on bone remodeling and peri-implant tissue.Materials and methodsFive models with different abutment taper configurations (10 degrees, 20 degrees, 30 degrees, 40 degrees, and 50 degrees) were analyzed using finite element analysis (FEA) to evaluate the biomechanical responses in peri-implant bone and the hydrostatic pressure in peri-implant tissue.ResultsThe results demonstrated that the rate of increase in bone density was similar in all models. On the other hand, the hydrostatic pressure in peri-implant gingiva revealed significantly different results. Model 10 degrees showed the highest maximum and volume-averaged hydrostatic pressures (69.31 and 4.5 mmHg), whereas Model 30 degrees demonstrated the lowest values (57.83 and 3.88 mmHg) with the lowest excessive pressure area. The area of excessive hydrostatic pressure decreased in all models as the degree of abutment taper increased from 10 degrees to 30 degrees. In contrast, Models 40 degrees and 50 degrees exhibited greater hydrostatic pressure concentration at the cervical region.ConclusionIn conclusion, the abutment taper configuration had a slight effect on bone remodeling but exerted a significant effect on the peri-implant gingiva above the implant platform via hydrostatic pressure. Significant decreases in greatest and average hydrostatic pressures were observed in the peri-implant tissues of Model 30 degrees. However, the results indicate that implant abutment tapering wider than 40 degrees could result in a larger area of excessive hydrostatic pressure in peri-implant tissue, which could induce gingival recession.
