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。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 commit-tee,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 modi-fied USPHS/Ryge criteria.The plaque index,gingival index,periodontal probing depth and attachment loss of the abut-ments 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 par-tial 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.
