摘要

目的研究聚醚醚酮（polyetheretherketone，PEEK）粘接桥修复牙周炎患者3颗以内切牙缺失的临床效果。方法本研究已通过单位伦理委员会审查批准，并获得患者知情同意。选择38例3颗以内切牙缺失的牙周炎患者，进行PEEK粘接桥修复，并于修复完成后3、6、12、24个月复诊，通过改良USPHS/Ryge标准评估修复体生存情况，分别记录基牙的菌斑指数、牙龈指数、牙周探诊深度和附着丧失，观察比较修复前后基牙牙周组织的变化。结果 38例患者经过24个月临床随访观察，其中仅1例出现部分脱粘接后行二次粘接，评价为B级，其余37例均修复成功，评价为A级。修复后菌斑指数、牙龈指数、牙周探诊深度较修复前明显降低，差异有统计学意义（P<0.05），附着丧失修复前后无明显变化（P>0.05）。结论对于缺失3颗以内切牙的牙周炎患者，PEEK粘接桥短期修复临床效果良好。

Abstract

Objective To study the clinical effect of a polyetheretherketone (PEEK) bonding bridge on the loss of 3 internal incisors in patients with periodontitis. Methods This study was reviewed and approved by the ethics committee, and informed consent was obtained from the patients. Thirty-eight patients with periodontitis and 3 missing central or lateral teeth were selected to undergo restoration with a PEEK bonding bridge and then returned to the hospital 3, 6, 12, and 24 months after the restoration was completed. The survival rate of the restorations was assessed by the modified USPHS/Ryge criteria. The plaque index, gingival index, periodontal probing depth and attachment loss of the abutments were recorded, and the changes in periodontal tissues after restoration were observed and compared. Results Over 24 months of clinical follow-up observation of 38 patients, only 1 patient underwent secondary bonding after partial debonding (evaluated as grade B), while bonding was successful in the other 37 cases (evaluated as grade A). The plaque index, gingival index and periodontal probing depth were significantly lower after restoration than before (P<0.05). There was no significant change in attachment loss between before and after restoration (P>0.05). Conclusion For periodontitis patients missing 3 internal incisors, short-term PEEK bonding bridge repair has good clinical efficacy.
