可摘式牙周夹板修复治疗牙周炎的临床效果分析

目的：评价可摘式牙周夹板对牙周炎伴牙列缺损患者的修复效果。方法：选取40例，随机分为2组，每组20例。两组患者行牙周基础治疗后，分别采用可摘式牙周夹板修复和可摘局部义齿修复，观察并记录不同时段各相关牙周指数。结果：可摘式牙周夹板组修复后24个月时菌斑指数（ plaque index，PLI）和出血指数（ bleeding in-dex，BI）较修复前增加（P＜0.05）；但修复后12个月和24个月时牙周探诊深度（periodontal probing depth，PD）较修复前下降，差异均有统计学意义（P＜0.05）。可摘局部义齿修复组修复后12个月和24个月时均出现PLI、BI和PD较修复前明显增加（P＜0.05）。结论：可摘式牙周夹板可改善牙周炎伴有牙列缺损患者的牙周状况，其修复疗效优于可摘局部义齿。

Evaluation of clinical efficacy of removable periodontal splints in periodontitis

Objective:To study the effect of removable periodontal splint with cast framework on dental arch with pe-riodontitis. Methods:Initial periodontal therapy was applied to 40 eligible patients that were randomly assigned either to re-movable periodontal splint or to removable partial denture. The changes were observed and recorded about relevant periodontal index at different time. Results:The plaque index( PLI) and bleeding index( BI) of the assessed teeth in removable periodon-tal splint group increased after 24 months(P<0. 05). However,the periodontal probing depth(PD)decreased after 12 and 24 months statistically(P<0. 05). And PLI,BI and PD of the assessed teeth in removable partial denture group increased after 12 months(P<0. 05). Conclusion:Removable periodontal splint can improve the periodontal status of chronic periodontitis, and it is more effective than removable partial denture.
