To observe the effect of orthodontics combined with restoration on masticatory function in deep overbite patients with severe lower anterior teeth attrition.
From January 2018 to January 2022, a total of 164 deep overbite patients with severe lower anterior teeth attrition were collected and divided into two groups according to different treatment plans: control group(72 patients, with restoration treatment) and experimental group(92 patients, with orthodontics combined with restoration treatment). The chewing efficiency of the two groups was evaluated, temporomandibular joint dysfunction index (DI), muscle palpation index (PI) and cranio-mandibular index (CMI) were calculated. The satisfaction with facial esthetic, the Chinese version of Oral Health Impact Scale-14(OHIP-14) and the repair satisfaction score were evaluated, the occurrence of adverse events between the two groups was compared. SPSS 23.0 software package was used for statistical analysis.
After treatment, the chewing efficiency of the experimental group was significantly improved compared to the control group, while the DI, PI, and CMI were significantly reduced compared to the control group(P＜0.05). Compared with the control group, the satisfaction degree with facial esthetic and restoration in the experimental group was significantly higher, while the OHIP-14 score was significantly lower after treatment(P＜0.05). The incidence of adverse events in the experimental group was significantly decreased compared with the control group (6.52% vs 25.00%, P＜0.05).
Combination of orthodontics and restoration treatment can enhance the effectiveness of restoration treatment for deep overbite with severe lower anterior teeth attrition, improve the mastication function and temporomandibular joint balance,satisfaction and quality of life of patients, as well as reduce the risk of adverse events.
观察正畸联合修复治疗对重度下前牙磨损深覆合患者咀嚼功能的影响。
收集2018年1月至2022年1月期间164例重度下前牙磨损深覆合患者，根据不同治疗方案分为两组：对照组（72例，采用修复治疗）和试验组（92例，采用正畸联合修复治疗）。评估两组的咀嚼效率，计算颞下颌关节功能障碍指数（DI）、肌肉触诊指数（PI）和颅下颌指数（CMI）。评估面部美观满意度、中文版口腔健康影响程度量表-14（OHIP-14）及修复满意度评分，比较两组不良事件的发生情况。采用SPSS 23.0软件包进行统计分析。
治疗后，试验组咀嚼效率较对照组显著提高，DI、PI和CMI较对照组显著降低（P＜0.05）。试验组面部美观及修复满意度较对照组显著更高，治疗后OHIP-14评分显著更低（P＜0.05）。试验组不良事件发生率较对照组显著降低（6.52% 比25.00%，P＜0.05）。
正畸与修复联合治疗可提高重度下前牙磨损深覆合修复治疗的效果，改善患者咀嚼功能和颞下颌关节平衡、满意度及生活质量，并降低不良事件风险。
