铸造Twin-Flex卡环修复KennedyⅡ类牙列缺损的临床应用

Clinical application of casted Twin-Flex clasp for restoration of Kennedy Ⅱ dentition defect

目的研究整体铸造法制作的Twin-Flex卡环在KennedyⅡ类牙列缺损修复中的使用效果。方法15例KenendyⅡ类牙列缺损患者,应用铸造支架材料整体铸造Twin-Flex卡环进行活动义齿修复,评价义齿的美学效果,固位、支持及稳定性。结果 15例患者,采用整体铸造法制作的Twin-Flex卡环,KennedyⅡ类牙列缺损的末端基牙避免了唇颊侧卡环的暴露,美学效果良好,义齿固位、支持及稳定效果良好。结论整体铸造法制作的Twin-Flex卡环应用于KennedyⅡ类牙列缺损修复,符合游离端设计的基牙及牙槽骨生物力学要求,可取得较好的美学效果及临床应用效果。

Objective Tu evaluate the effect of casted Twin-Flex clasp used on the terminal abutment of unilateral free ending dentition defect. Methods Fifteen cases were selected,and the casted Twin-Flex clasp was used on the ter- minal abutment of unilateral free ending dentition defect. Results The casted Twin-Flex clasp used on the terminal abut- ment of unilateral free ending dentition defect conformed to the biomechanics rule of the terminal abutment and the eden- tulous ridge. Better retention and stabilization of the removable partial denture were achieved. Conclusion The use of casted Twin-Flex clasp on terminal abutment could provid a satisfactory result for unilateral free ending dentition defect.
