| 目的分析骨性Ⅲ类错颌患者正畸正颌联合治疗后上中切牙牙根吸收情况及其影响因素。 方法收集骨性Ⅲ类错颌患者80例160颗上中切牙在正畸正颌联合治疗后的一般资料。采用David根吸收分级法评估牙根吸收情况。根据正畸正颌治疗后患者是否发生牙根吸收分为吸收组与未吸收组。比较两组患者的一般资料,采用Logistic回归分析骨性Ⅲ类错颌患者上中切牙在正畸正颌治疗后发生牙根吸收的影响因素。 结果术后32例患者60颗(37.50%)上中切牙发生牙根吸收,其中牙根吸收评分3分48颗,2分10颗,1分2颗,平均吸收量为(2.11±0.76)mm。两组患者的牙根发育情况、治疗疗程、上中切牙牙齿移动距离、是否拔牙及余留牙周膜面积估值比较,差异有显著性(P＜0.05)。 Logistic回归分析显示,牙根发育情况、治疗疗程及是否拔牙是骨性Ⅲ类错颌患者正畸正颌治疗过程中上中切牙发生牙根吸收的独立危险因素。 结论骨性Ⅲ类错颌患者正畸正颌治疗后上中切牙发生牙根吸收率为37.50%；牙根发育情况、治疗疗程及治疗过程中是否拔牙是上中切牙发生牙根吸收的影响因素。 |

| AimTo analyze the root resorption of upper central incisor and its influencing factors in patients with skeletal class Ⅲ malocclusion after orthodontic-orthognathic treatment. MethodsThe general data of 160 upper central incisor teeth in 80 patients with skeletal class Ⅲ malocclusion after orthodontic-orthognathic treatment were collected.The root resorption of teeth was evaluated by David root resorption grading method. The patients were divided into absorption group and non-absorption group according to whether or not root resorption occurred after orthodontic orthognathic treatment. The general data of the two groups were compared, and Logistic regression was used to analyze the influencing factors of root resorption of upper central incisor in patients with skeletal class Ⅲ malocclusion after orthodontic-orthognathic treatment. ResultsRoot resorption occurred in 60 (37.50%) upper central incisor teeth of 32 patients after surgery.Among them, the root absorption score was 3 for 48 teeth, 2 for 10 teeth, and 1 for 2 teeth, with an average absorption of (2.11±0.76) mm. There were significant differences between the two groups in tooth root development, treatment course, tooth travel distance of upper central incisor, presence of tooth extraction, and remaining periodontal membrane area (P＜0.05). Logistic regression analysis showed that the status of tooth root development, duration of treatment and presence of tooth extraction was an independent risk factor for root resorption of upper and middle incisors during orthodontic-orthognathic treatment in patients with skeletal class Ⅲ malocclusion. ConclusionThe root absorption rate of upper central incisor was 37.50% in patients with class Ⅲ malocclusion after orthodontic-orthognathic treatment. Root development, treatment course and tooth extraction during treatment are the factors affecting root resorption of upper central incisor. |
