SJ -1型插销式附着体可摘义齿的咀嚼效能分析

Clinical Study of Masticatory Efficiency of Removable Partial Denture with SJ 1 Type Bolt Attachment

目的 对戴有SJ 1型插销式附着体义齿的患者进行咀嚼效能的测试分析。方法 选择 16例末端游离缺失患者 ,用SJ 1型附着体义齿修复后 ,采用吸光度法测定咀嚼效能 ,并与正常组及戴传统义齿者比较。结果 16例患者初戴附着体义齿 1周后吸光度均值为 0 876 ,3周后为 0 85 9,1月后为 0 985 ,无显著差异。与正常牙列者吸光度均值比较 ,P >0 0 5 ;与戴传统活动义齿者比较 ,P <0 0 1,有高度显著性差异。结论 SJ

Objective Measurement and analysis of patients wearing dentures with SJ 1 type bolt attachments.Methods Select sixteen patients with free end edentulous spaces,restore with removable dentures using SJ 1 type bolt attachments,measure the masticatory efficiency using light absorption method,and compare them with those of normal occlusion and traditional removable partial dentures.Results (1)One week after the dentures delivered,the average absorption value of these sixteen patients was 0.876,three weeks later 0.859,one month later 0.985. There was no significant difference among them. (2)Compared with those of normal occlusion, P >0.05,no significant difference;with those wearing traditional dentures, P <0.01,high significant difference.Conclusion The matiscatory efficiency of the patients wearing dentures with SJ 1 type bolt attachments was much better than those of traditional removable partial dentures.
