分析改良粘接固位种植义齿修复疗法对后牙缺损患者牙槽骨高度及厚度、骨吸收量的影响

Analysis of the Effects of Improved Adhesive Fixation Implant Denture Re⁃ pair Therapy on Alveolar Bone Height, Thickness, and Bone Resorption in Patients with Posterior Tooth Defects

目的分析改良粘接固位种植义齿修复疗法对后牙缺损患者的影响。方法简单随机选取2021年7月—2023年7月镇江市口腔医院收治的80例后牙缺损患者为研究对象,依据不同修复方法分为对照组和观察组,各40例。对照组行传统粘接固位种植义齿修复,观察组行改良粘接固位种植义齿修复。对比两组患者牙槽骨高度及厚度、骨吸收量、牙周健康情况、龈沟液炎症因子水平。结果治疗后,观察组唇侧牙槽骨高度与厚度分别为(6.12±1.34)mm、(0.79±0.18)mm,均高于对照组的(5.35±0.89)mm、(0.66±0.15)mm,观察组骨吸收量为(4.70±0.42)mm,低于对照组的(5.89±0.76)mm,差异有统计学意义(t=3.027、3.509、8.667,P均<0.05)。治疗后,观察组的菌斑指数、牙龈指数龈沟液内各炎症因子水平、探诊深度均低于对照组,差异有统计学意义(P均<0.05)。结论改良粘接固位种植义齿修复疗法能够阻碍种植体四周骨吸收,改善牙周健康,减轻炎症反应。

Objective To analyze the impact of improved adhesive fixation implant denture repair therapy on patients with posterior tooth defects.Methods A total of 80 patients with posterior teeth defect who received repair treatment in Zhenjiang Stomatological Hospital from July 2021 to July 2023 were simple randomly selected as the research objects and divided into control group and observation group according to different repair methods,with 40 cases in each group.The control group underwent traditional adhesive retention implant denture repair,and the observation group underwent modified adhesive retention implant denture repair.The height and thickness of alveolar bone,bone resorption,periodontal health,and levels of inflammatory factors in gingival crevicular fluid were compared between the two groups.Results After treatment,the height and thickness of labial alveolar bone in the observation group were(6.12±1.34)mm and(0.79±0.18)mm,respectively,which were higher than(5.35±0.89)mm and(0.66±0.15)mm in the control group,the bone resorption in the observation group was(4.70±0.42)mm,which was lower than(5.89±0.76)mm in the control group,and the differences were statistically significant(t=3.027,3.509,8.667,all P<0.05).After treatment,the plaque index,gingival index,levels of inflammatory factors in gingival crevicular fluid and probing depth in the observation group were lower than those in the control group,and the differences were statistically significant(all P<0.05).Conclusion The improved adhesive fixation implant denture repair therapy can inhibit bone resorption around the implant,improve periodontal health,reduce inflammatory reactions.
