Clinical effect of orthodontic traction combined with multidisciplinary comprehensive treatment for residual tooth roots
口腔正畸牵引联合多学科综合治疗牙残根的临床效果

摘要

目的 探讨口腔正畸牵引联合多学科综合治疗牙残根的临床效果，旨在提高牙残根保留率及改善患者口腔功能与美观。方法 选取2022年11月至2024年11月期间收治的100例不适合直接桩核冠修复的牙残根患者作为研究对象，随机分为对照组和研究组各50例。对照组采用常规治疗方法，包括根管治疗后直接进行桩核冠修复；研究组在常规治疗基础上增加口腔正畸牵引治疗。观察指标设定为牙周指数（GPI）、探诊深度（PD）、附着丧失（AL）、牙齿松动度（MTD）以及患者满意度评分（PSS），所有数据均于治疗前、后进行统计分析。结果 治疗后，研究组GPI从平均3.6降至1.2，PD由平均4.5mm减少到2.8mm，AL从平均2.9mm降低至1.4mm，MTD由平均2级改善为1级，PSS从平均65分提升到89分。对照组上述指标改善幅度较小，具体为GPI 4.6下降至2.7，PD减少到3.7mm，AL降至2.3mm，MTD稳定在1.5级，PSS增至76分。两组间比较，研究组各项指标改善更为显著，差异具有统计学意义(P<0.05)。结论 通过将口腔正畸牵引技术与多学科综合治疗相结合应用于不适合直接桩核冠修复的牙残根病例中，能够有效增强牙残根的保存成功率，促进牙周组织健康恢复，提高患者的生活质量和对治疗效果的满意程度。此疗法为牙残根提供了一种新的治疗思路，并证明了其临床应用价值。

Abstract

Objective To investigate the clinical effect of orthodontic traction combined with multidisciplinary comprehensive treatment for residual tooth roots, aiming to improve the retention rate of residual tooth roots and enhance patients' oral function and aesthetics.
Methods A total of 100 patients with residual tooth roots unsuitable for direct post-and-core crown restoration admitted between November 2022 and November 2024 were selected and randomly divided into a control group and a study group, with 50 patients in each. The control group received conventional treatment, including post-and-core crown restoration directly after endodontic treatment; the study group received orthodontic traction treatment on the basis of conventional treatment. Observational indicators were set as gingival papillary index (GPI), probing depth (PD), attachment loss (AL), mobility of teeth (MTD), and patient satisfaction score (PSS). All data were statistically analyzed before and after treatment.
Results After treatment, the GPI in the study group decreased from an average of 3.6 to 1.2, PD decreased from an average of 4.5 mm to 2.8 mm, AL decreased from an average of 2.9 mm to 1.4 mm, MTD improved from an average grade of 2 to grade 1, and PSS increased from an average of 65 to 89. The improvement in these indicators was smaller in the control group, specifically with GPI decreasing from 4.6 to 2.7, PD decreasing to 3.7 mm, AL decreasing to 2.3 mm, MTD stabilizing at grade 1.5, and PSS increasing to 76. Comparison between the two groups showed that the improvement in various indicators was more significant in the study group, with a statistically significant difference (P<0.05).
Conclusion   The combination of orthodontic traction technology and multidisciplinary comprehensive treatment for cases of residual tooth roots unsuitable for direct post-and-core crown restoration can effectively enhance the success rate of residual tooth root preservation, promote the healthy recovery of periodontal tissues, and improve patients' quality of life and satisfaction with treatment outcomes. This treatment provides a new therapeutic approach for residual tooth roots and demonstrates its clinical application value.
