摘要/Abstract

摘要： [摘要] 目的: 探讨应用固定-可摘联合修复技术对遗传性乳光牙本质患者进行咬合重建的制作方法及效果评价。方法:对南京发现的1例遗传性乳光牙本质患者调查家族史，比对该病的遗传特征。对患者通过3个月暂时性修复体的试戴与咬合调整建立最适下颌位，在此位置进行固定-可摘联合修复体的设计和制作。修复后定期随访5年，可摘局部义齿主要从安全性、强度、适合性三方面进行评价。固定义齿参照改良的美国公共卫生署评价标准对修复体的临床修复效果进行综合评价，多独立样本Kruskal-Wallis H非参数检验（a=0.05）进行统计分析。结果:该患者家族中遗传性乳光牙本质连续三代出现，子代患病率50%，符合常染色体显性遗传特征。其他受累者义齿修复率100%，修复方法均为全口义齿。我们对患者进行固定-可摘联合修复治疗并随访5年。患者修复后主观感觉咀嚼功能提高、舒适性良好、面型改善、恢复美观、无颞下颌关节不适。修复体检查结果显示边缘密合，牙龈颜色形态自然，无牙龈炎，修复体色泽自然逼真，未出现破裂、崩瓷、脱落、基牙冠折等并发症。修复体在各评价项目上均无统计学差异（P>0.05）。结论:采用固定-可摘联合修复技术治疗遗传性乳光牙本质患者，进行咬合重建的效果令人满意。

Abstract: [Abstract]Objective:To perform occlusal restoration for dentinogenesis imperfeca with fixed-removable dentures, observe the clinic effect and summarize the clinical experience. Methods: The data of one family of dentinogenesis imperfeca were collected, analysing genetic characteristics of the disease. By making provisional restorations for 3 months. When the occlusion were in a stable condition, the final fixed-removable dentures were made. Patient was followed up 5 years. To evaluate the dentures from safety, strength and suitability, using improved evaluation criteria for the United States Department of public health. Using statistical analysis of non parametric test(a=0.05) for multiple independent samples H Kruskal-Wallis to analyse the data. Results: Family of three successive generations of dentinogenesis imprfecta appeared. The prevalence of offspring was 50%, it is the features of autosomal dominant characteristic. The others were restored using complete dentures. The patient was restored using fixed-removable dentures and followed up 5 years. The patient felt comfortable, the esthetics and mastication function were significantly improved. The clinical examinations show natural color, fitted margin, healthy gums, and no fracture or fall off of the dentures. There were no significant differences in all the evaluation items(P>0.05). Conclusion: Occlusal restoration with fixed-removable dentures may yield favorable clinical effect.
