摘要
目的:评估不同穿龈高度的基台对国人种植磁性覆盖总义齿性能的影响。方法:20例无牙颌患者分别按其所用磁性基台穿龈高度(1.5、2.5、3.5、4.5mm)的不同分为四组,按常规修复每一组的种植磁性覆盖总义齿,观察其固位力、基托断裂率、是否影响基台区的排牙等情况。结果:3.5mm穿龈高度的磁性基台在修复种植磁性覆盖总义齿时与1.5、2.5、4.5mm的基台在覆盖率义齿的固位力、基托断裂率以及影响基台区的排牙方面存在高度显著性差异。结论:3.5mm磁性基台可能是国人修复种植磁性覆盖总义齿的较适基台高度。
To study if the different high abutment of implants influence to magnetic overdentures of china people. Methods: 20 patients were divided into four groups according to the different high abutment of implants (1.5,2.5,3.5,4.5mm), then to restore each group implant- supported magnetic overdentures routine, and observe retention of denture ,fracturing of base,if influence on arranging artificial tooth and so on after placing magnetic attachment respectively. Results: Retention of denture ,fracturing of base ,if influence on arranging artificial tooth of 3.5mm group existed significantly differences(P 〈 0.01)among anther three groups after treatment. Conclusion: It suggests that 3.5mm be appropriate high implants abutment of magnetic overdentures to china people.
