牙周健康程度对牙周炎种植修复后机械并发症及菌斑控制的影响分析(1)
【摘要】 目的：分析牙周健康程度對牙周炎种植修复后机械并发症及菌斑控制的影响。方法：选取2016年9月-2017年9月在本院诊疗的68例牙周炎患者为研究对象，根据第1次就诊时牙周疾病严重程度和诊断，分为健康组(n=20)、轻中度组(n=23)、重度组(n=25)。比较三组人均缺牙数、接触区过长的种植体、临床冠根比、机械并发症、种植体留存率、菌斑指数;比较轻中度组、重度组的牙周情况;分析患者食物嵌塞、种植体接触松紧度率。结果：健康组人均缺牙数、接触区过长的种植体、临床冠根比均优于轻中度组、重度组，差异均有统计学意义(P<0.05);三组种植体留存率均为100%，107颗种植体中发生机械并发症13颗(12.15%)，三组并发症发生率比较，差异无统计学意义(P>0.05);健康组食物嵌塞率为4.17%、邻接触过紧率为4.17%、邻接触丧失率为12.5%，均明显低于轻中度组和重度组，差异均有统计学意义(P<0.05);T2时，健康组种植体菌斑指数均低于轻中度组和重度组，且轻中度组低于重度组，差异均有统计学意义(P<0.05)。结论：牙周炎的严重程度对种植修复体机械并发症的影响不大，但是牙周健康的患者在菌斑控制上有着更好的效果，针对重度患者在种植修复方案制定中，要适当关闭邻间隙，让患者更好的维持口腔卫生，以提高修复体存留率。

【Abstract】 Objective：To analyze the effect of periodontal health on mechanical complications and plaque control after implant restoration of periodontitis.Method：A total of 68 patients with periodontitis from September 2016 to September 2017 in our hospital were selected.According to the severity and diagnosis of periodontal disease at the first visit，they were divided into healthy group(n=20)，mild to moderate group(n=23)and severe group(n=25).The number of missing teeth per capita，implants，implants with long contact area，clinical crown-root ratio，mechanical complications，implant retention rate and plaque index among the three groups were compared，the periodontal conditions of mild to moderate group and severe group were compared，and the relationship between food impaction and implant contact tightness was analyzed.Result：The number of missing teeth per capita，implants with long contact area and clinical crown-root ratio in healthy group were better than those of mild-to-moderate group and severe group，the difference was statistically significant(P<0.05).The retention rate of implants in three groups was 100%，there were 13 mechanical complications in 107 implants，with a total incidence of 12.15%.The incidence of complications in three groups was compared，the difference was not statistically significant(P>0.05).The food impaction rate，the overcontact rate and the loss rate of adjacent contact in healthy group were 4.17%，4.17% and 12.5%，which were significantly lower than those of mild to moderate and severe groups，the differences were statistically significant(P<0.05).At T2，the plaque index of implants in healthy group was lower than those of mild to moderate group and severe group，and that in mild to moderate group was lower than that of severe group，the differences were statistically significant(P<0.05).Conclusion：The severity of periodontitis has a little effect on the mechanical complications of implant prostheses，but the patients with periodontal health have better effect on plaque control，in the formulation of implant prostheses for severe patients，it is necessary to close the adjacent space appropriately，so that patients can maintain better oral hygiene，so as to improve the retention rate of prostheses., http://www.100md.com(朱光恒 黄美玲 周筱怡)
