摘要
目的:研究种植固定义齿和邻牙之间出现邻接触丧失的发病率,并探讨其可能的影响因素。方法:从2012年9月~2017年9月期间,对105例完成种植修复的患者进行随访复查,截止2017年9月共纳入研究164颗种植固定义齿。研究方法是利用不同厚度的邻接触检查铝片,在规定的时间段内检测邻接触的紧密程度。如果邻接触超过50μm,被认为是邻接触丧失,从而进行统计学分析,评估邻接触丧失的发病率及其可能的影响因素。结果:纳入研究的105例患者,共计210个邻接触点,其中有107个接触点被视为邻接触丧失(50.9%)。种植牙与邻牙的接触位置(近中/远中),邻牙的牙槽骨水平,颌骨的位置等因素会影响邻接触丧失。统计学分析显示,此结果具有统计学意义(P<0.05)。结论:本研究表明,种植固定义齿邻接触丧失的发病率高。种植体的近中接触区发生邻接触丧失的几率远大于远中;上颌的发病率高于下颌;邻牙的牙根数越少,邻牙的牙槽骨吸收越多,其发生邻接触丧失的几率越高。
Objective：To study the incidence of loss of interproximal contact between implant fixed denture and adjacent teeth,and to investigate its possible related factors.Methods：From September 2012 to September 2017,105 patients were followed up,and at the end of September 2017,a total of 164 implant fixed dentures were studied.After crown/bridge restorations,different thickness of adjacent contact was used to analylze the interproximal contact.If the interproximal contact was over 50μm,it was considered as the interproximal contact loss.Furthermore,the incidence of the loss of interproximal contact and its possible influencing factors were evaluated.Results：Totally,there were 210 interproximal contacts,of which 107 were the loss of interproximal contact（50.9%）.The interproximal contact position,the level of alveolar bone in the adjacent teeth,and the jaw position could affect the loss of interproximal contact.According to statistical analysis,those results had statistical significance（P〈0.05）.Conclusion：The loss of interproximal contact is one of the complications of implant denture with a higher incidence.The results showed that the incidence of interproximal contact loss of maxillary is higher than that of mandible.The mesial contact is easily loss than the distal contact.In addition,the number of adjacent dental root and the alveolar bone absorption of adjacent teeth are also associated with the loss of interproximal contact.
