目的观察正畸与修复联合治疗牙列缺损伴牙颌畸形的临床疗效。方法资料随机选自2010年1月—2013年6月濮阳市人民医院诊治的牙裂缺损伴牙颌畸形患者86例,按照完全抽样法随机分成两组,对照组43例患者予直接烤瓷冠桥修复方案治疗,研究组43例患者先予正畸方案治疗,待牙齿条件达到预期标准后在行种植体修复治疗,比较两组患者治疗后的疗效性指标与远期预后情况。结果研究组患者的牙恢复时间比对照组长,治疗费用比对照组高,差异有统计学意义(P<0.01);研究组患者修复12个月的骨吸收量(0.61±0.34)mm比对照组(0.81±0.28)mm低,PES评分(12.84±1.56)分比对照组(10.35±2.16)分高,差异有统计学意义(P<0.05);研究组患者随访时的前牙覆盖、后牙咬颌、牙齿整齐良好率均比对照组高,差异均有统计学意义(P均<0.05)。结论牙列缺损伴牙颌畸形患者应用正畸联合修复方案治疗的临床效果显著,对牙外观与牙功能的恢复均具有积极意义。
Objective To observe the clinical effect of combined orthodontic and repair on dentition defect with dentition deformity. Method data were randomly selected from January 2010 - June 2013 in Puyang City People’s Hospital for diagnosis and treatment of tooth dehiscence with deformity and malocclusion in 86 patients, according to complete sampling method were randomly divided into two groups, the control group of 43 patients with direct porcelain crown Bridge rehabilitation program treatment, the study group of 43 patients treated with orthodontic treatment until the tooth conditions to achieve the desired standard in the line of implant repair treatment, the efficacy of the two groups were compared after treatment indicators and long-term prognosis. Results The recovery time of teeth in the study group was longer than that of the control group, and the cost of treatment was higher than that of the control group (P <0.01). The bone resorption volume of the study group at 12 months was 0.61 ± 0.34 mm Group (0.81 ± 0.28) mm, PES score (12.84 ± 1.56) points higher than the control group (10.35 ± 2.16), the difference was statistically significant (P <0.05); the study group patients at the time of follow- The teeth were well-nipped and the teeth were well-proportioned. The differences were statistically significant (all P <0.05). Conclusion The clinical effect of orthodontic joint repair in patients with dentition defect and dento-maxillofacial deformity is significant. It has positive significance to the restoration of tooth appearance and dental function.
