正畸-正颌联合治疗骨性Ⅲ类错(牙合)畸形的临床疗效及对侧貌软硬组织变化的影响OACSTPCD
Clinical Curative Effect of Orthodontic and Orthognathic Combined Therapy on Skeletal Class Ⅲ Malocclusion and Its Influences on Orthodontic Effect and Soft and Hard Tissue Changes of Facial Profile
目的:观察正畸-正颌联合治疗对骨性Ⅲ类错(牙合)畸形临床疗效、正畸效果及侧貌软硬组织变化的影响.方法:选取2019年12月-2021年1月在笔者医院口腔科进行正畸-正颌联合治疗的70例青少年骨性Ⅲ类错(牙合)畸形患者为研究对象,均于正畸-正颌治疗前后拍摄头颅侧位X线片,获取头颅侧位片,分别测量患者牙性、骨性及软组织等相应指标,并收集35例同期来院进行口腔检查的正常(牙合)患者作为对照,观察患者正畸效果及侧貌软硬组织变化情况.并观察患者口腔相关生活质量变化情况.结果:整体治疗结束后,UI-NA、UI-LI角度均较正畸治疗前减小,LI-NB角度较正畸治疗前增大(均P＜0.05);UI-NA距离较正畸治疗前缩短、LI-NB距离较正畸治疗前增大(均P＜0.05);SNA、LI-MP角度均较正畸治疗前增大(均P＜0.05),SNB、ANB、MP-SN角度均较正畸治疗前减小(均P＜0.05);面凸角、鼻唇角较正畸治疗前增大(P＜0.05),颏唇角、软组织面角均较正畸治疗前减小(均P＜0.05);Sn、UL'点至VRL距离均较正畸治疗前增大,LL'、Pg'、Si点至VRL距离均较正畸治疗前缩短(均P＜0.05).正颌术后1个月与整体治疗结束后各项指标比较差异无统计学意义(P＞0.05).整体治疗结束后,OHRQOL评分较正畸治疗前降低(P＜0.05),且低于正畸治疗后及正颌术后1个月(均P＜0.05).结论:正畸-正颌联合具有较好的正畸效果,可有效改善患者的侧貌软硬组织,且稳定性较好.
Objective To observe clinical curative effect of orthodontic and orthognathic combined therapy on skeletal ClassⅢ malocclusion and its influences on orthodontic effect and soft and hard tissue changes of facial profile.Methods A total of 70 adolescent patients with skeletal Class Ⅲ malocclusion undergoing orthodontic and orthognathic combined therapy in stomatology department of the hospital were enrolled between December 2019 and January 2021.Before and after combined therapy,lateral cephalic radiographs were obtained by taking lateral X-rays.The dentition,bone and soft tissue indexes were detected.A total of 35 normal occlusion objects undergoing oral examinations during the same period were enrolled as controls.The orthodontic effect and changes in soft and hard tissues of facial profile and oral health-related quality of life scale(OHRQOL)were observed.Results After holistic treatment,UI-NA and UI-LI angles were lower than those before treatment,while LI-NB angle was greater than that before treatment(all P＜0.05);UI-NA distance was shorter than that before treatment,while LI-NB distance was longer that that before treatment(all P＜0.05);SNA and LI-MP angles were greater than those before treatment(all P＜0.05),while SNB,ANB and MP-SN angles were lower than those before treatment(all P＜0.05);Posterior convex angle and nasolabial angle were greater than that before treatment(P＜0.05),while mentolabial angle and facial angle of soft tissue were lower than those before treatment(P＜0.05).After treatment,distance from Sn and UL to VRL was longer than that before treatment,while distance from LL´,Pg´ and Si to VRL was shorter than that before treatment(all P＜0.05).There was no significant difference in any index between at 1 month after orthognathic surgery and after holistic treatment(P＞0.05).The OHRQOL score after holistic treatment was lower than that before treatment(P＜0.05),and was lower than that after orthodontic treatment and 1 month after orthognathic surgery(all P＜0.05).Conclusion Orthodontic and orthognathic combined therapy has good orthodontic effect,which can effectively improve soft and hard tissues of facial profile,with good stability.
