[摘要]目的：分析強力纤维强化树脂夹板在牙周病松动牙中的应用及效果。方法：选择笔者医院2017年2月-2019年4月收治的94例牙周病患者，依据随机数字表法分为对照组和研究组，每组47例。两组均予以完善的牙周基础治疗，研究组采用强力纤维强化树脂夹板固定，对照组采用不锈钢丝联合树脂夹板固定。比较两组临床疗效、牙槽骨密度、牙周情况及牙周夹板满意度。结果：研究组和对照组有效率比较，差异无统计学意义（P>0.05）。固定前，两组牙齿骨密度差异比较无统计学意义（P>0.05）;固定后，两组牙齿骨密度均增加，组间比较差异无统计学意义（P>0.05）。固定前，两组牙周探诊深度（PD）、附着丧失（AL）、牙菌斑指数（PLI）比较，差异无统计学意义（P>0.05）;固定后，研究组PD、AL、PLI较固定前无明显改变（P>0.05）;对照组PD、AL、PLI较固定前上升，研究组低于对照组（P<0.05）。研究组舒适度和美观性高于对照组（P<0.05）。结论：强力纤维强化树脂夹板对牙周病松动牙的固定效果显著，能够抑制牙槽骨吸收，改善患者舒适度和美观，且对牙周状态的影响较小。

Abstract： Objective  To analyze the application and effect of strong fiber reinforced resin splint in periodontal loose teeth. Methods  94 patients with periodontal disease admitted to our hospital from February 2017 to April 2019 were selected and divided into control group and research group according to the random number table method， with 47 cases in each group. Both groups received complete periodontal basal treatment， the research group was fixed with strong fiber reinforced resin splint， while the control group was fixed with stainless steel wire combined with resin splint. Then clinical efficacy， alveolar bone density， periodontal status and satisfaction of periodontal splint were compared between the two groups. Results  There was no significant difference between the effective rate of research group and control group （P>0.05）. Before fixation， there was no significant difference in bone density between the two groups （P>0.05）. After fixation， the bone density of teeth in both groups increased， and there was no significant difference between the two groups （P>0.05）. Before fixation， there was no significant difference in periodontal depth （PD）， attachment loss （AL）， and plaque index （PLI） between the two groups （P>0.05）. After fixation， PD， AL and PLI in the research group were not significantly changed compared with that before fixation （P>0.05）. PD， AL and PLI in the control group were higher than those in the control group before fixation， while those in the research group were lower than those in the control group （P<0.05）. The comfort and aesthetics of the research group were higher than that of the control group （P<0.05）. Conclusion  The strong fiber reinforced resin splint has a significant effect on the fixation of the loosening pressure of periodontal disease， can inhibit the absorption of alveolar bone， improve comfort and beauty of patients， and has little effect on the periodontal state.

牙周病为口腔科常见疾病，早期症状不明显，随着疾病进展导致牙周组织长期慢性感染，炎症反复发作，临床以牙槽骨吸收、牙齿松动为主要症状，最终因牙齿移位导致牙齿缺失，明显影响患者口腔咀嚼系统功能和美观[1]。调查研究报道[2]，牙周炎可能引起或加重感染性心内膜炎的发生，威胁患者身体健康。又有研究表明[3]，牙周病是临床拔牙的主要原因之一，且是引起牙列缺损及缺失的主要原因。牙周病经基础治疗后能够较好控制牙周炎症，一定程度缓解牙齿松动，但牙槽骨吸收不可逆，牙齿动度仍无法完全恢复，导致继发性咬合创伤加重牙齿松动，形成恶性循环，导致口腔功能恢复不良。牙周夹板固定松动牙能……
