【摘要】：目的：1.利用CBCT定量评价SARME和SFOT治疗成年正畸患者上颌宽度不足后对上颌骨及其周围骨缝、下颌位置和上气道的影响。2.对治疗上颌宽度不足时牙槽骨量的治疗前后的变化进行评估。方法：选取山东省口腔医院正畸患者伴上颌宽度不足者20例,年龄范围为22-32岁,平均年龄25岁,进行SARME和SFOT治疗。所有患者扩弓均采用个性化铸造的牙合面开孔的粘结式快速扩弓器,有一定的牙合垫作用。患者在SARME和SFOT治疗前后分别拍摄CBCT,治疗后拍摄时间为扩弓达临床目标后维持3月后。对治疗前后的CBCT进行分析,对上颌骨及其周围骨缝、下颌位置和上气道进行线距,角度,截面积及体积的测量分析,并对所得数据进行统计学分析。结果：1.对比治疗前后测量结果发现上颌骨及牙弓宽度,双侧上颌骨周围骨缝间距离(颧上颌缝及翼钩)和Ba-PNS距离两组均有显著性增加(P0.05)。上颌扩弓装置的牙合垫作用使上颌有前上移位伴不同方向的旋转,鼻咽在Ba-PNS水平有显著性的增加,下颌发生顺时针旋转,PP-C3iHy围成上气道有明显改善。2.治疗后的上后牙相对牙槽骨的相对位置角度变化无显著性差异(P0.05),治疗后牙槽骨量有增加,统计学显示有显著性差异(P0.05)。结论：1.上颌宽度不足患者经治疗后上颌宽度及其周围骨缝间距和鼻咽及上气道容积有明显改善。2. SARME+SFOT治疗后牙槽骨量改变方面有显著性增加。
[Abstract]:Purpose 1.The effects of SARME and SFOT on maxillary suture, mandibular position and upper airway in adult orthodontic patients were quantitatively evaluated by CBCT.To evaluate the changes of alveolar bone mass before and after treatment for maxillary width deficiency.Methods: twenty cases of orthodontic patients with inadequate maxillary width in Shandong Stomatology Hospital were selected. The age ranged from 22 to 32 years with an average age of 25 years. The patients were treated with SARME and SFOT.All the patients used the bonding rapid arch expander with individualized casting of the opening of the occlusal surface, which had the effect of occlusal pad.The patients were photographed before and after treatment with SARME and SFOT respectively.CBCT was analyzed before and after treatment, and the distance, angle, sectional area and volume of maxillary bone and its surrounding sutures, mandibular position and upper airway were measured and analyzed statistically.The result is 1: 1.The results before and after treatment showed that the width of maxilla and dental arch, the distance between bilateral maxillary periraphe (zygomatic-maxillary suture and pterygoid hook) and Ba-PNS were significantly increased in both groups (P 0.05).The occlusal pad of maxillary arch expansion device caused the maxillary anterior displacement and rotation in different directions, the nasopharynx increased significantly at the Ba-PNS level, and the mandibular clockwise rotation of PP-C3iHy in the upper airway was significantly improved.There was no significant difference in the relative position angle of the upper posterior teeth to alveolar bone after treatment (P 0.05), but the alveolar bone mass increased after treatment, and there was significant difference between the two groups (P 0.05).Conclusion 1.After treatment, the maxillary width and its surrounding suture space and nasopharyngeal and upper airway volume were significantly improved in patients with maxillary width deficiency.There was a significant increase in alveolar bone mass after SARME SFOT treatment.
