Prospective Clinical Study of Combined Treatment of Periodontal Orthodontics for Chronic Periodontitis
-
摘要:
目的 探讨牙周正畸联合治疗过程中咬合力动态监测对于最终治疗效果,以及牙周支持组织改变的影响。 方法 对比20例传统牙周正畸治疗患者与20例运用T-Scan III和Anycheck数字化咬合分析系统辅助分析的牙周正畸联合治疗患者在治疗前、中、后的牙周临床指数的不同,以及实验组咬合力变化、咬合时间变化和牙松动度值变化的情况。 结果 2组患者的牙周-正畸联合治疗后牙周袋深度(PD)、附着丧失(AL)、出血指数(BI)和牙松动度明显降低(P < 0.05);对照组前后牙咬合力百分比变化明显(P < 0.05),咬合平衡改善。 结论 牙周-正畸联合治疗能很好的改善牙周炎患者牙周组织情况,T-Scan系统能很好地观察和指导调整咬合,更好地达到咬合平衡。 Abstract:Objective To investigate the effect of dynamic monitoring of occlusal force on the final therapeutic effect and the change of periodontal supporting tissue during combined periodontal orthodontic treatment. Methods The periodontal clinical index of 20 patients with traditional periodontal orthodontic treatment and 20 patients with combined periodontal orthodontic treatment assisted by T-Scan III and Anycheck digital occlusion analysis system were compared before, during and after treatment, as well as the changes of bite force, bite time and tooth mobility in the experimental group. Results The depth of periodontal pocket(PD), loss of attachment(AL), bleeding index(BI) and tooth looseness were significantly reduced after combined periodontal orthodontic treatment in both groups. In the control group, the percentage of anterior and posterior biting force changed obviously, and the occlusion force balance was improved. Conclusion The combined treatment of periodontitis and orthodontics can improve the periodontal tissue of patients with periodontitis, and T-Scan system can observe and guide the adjustment of occlusal and better achieve occlusion force balance. -
