正畸-正颌联合治疗成人骨性Ⅲ类错(牙合)的疗效及其稳定性研究的开题报告一、研究背景和意义正畸治疗一直是临床口腔医学的重要分支之一。
骨性Ⅲ类错(牙合)是指上下颌骨错位引起的上下颌牙骨错合,是目前正畸学中最为复杂的病例之一,也是最为困难的病例之一。
该病例患者存在的问题包括口腔生理功能、口腔容貌、咬合力等多个方面,严重影响患者的生活质量。
传统的正畸治疗对于成人骨性Ⅲ类错(牙合)的疗效不佳,主要原因是骨骼发育已经完全,固定的颌骨已经形成,牙齿移动的空间有限,需要进行正颌联合治疗,即通过手术将上颌骨向后移动,下颌骨向前移动,从而恢复正常的牙骨关系。
但手术治疗带来的疼痛、创伤和疤痕等问题让患者望而却步。
因此,研究正畸-正颌联合治疗成人骨性Ⅲ类错(牙合)的疗效及其稳定性,对于改善患者生活质量、提高治疗效果具有重要的意义。
二、研究目的本研究旨在探讨正畸-正颌联合治疗成人骨性Ⅲ类错(牙合)的疗效及其稳定性,为临床提供科学、可靠的治疗方案。
三、研究内容和方法本研究为前瞻性研究,选取符合纳入标准的成人骨性Ⅲ类错(牙合)患者进行正畸-正颌联合治疗。
治疗方案采取自锁托槽矫治器,术前根据患者的X线片以及三维重建图像制作手术模板,在手术期间实施上颌后移/下颌前移手术。
治疗效果评估采用口腔疾病评估指数(Oral Health Assessment Questionnaire,OHAQ)和口腔健康质量生活问卷(Oral Health Related Quality of Life Questionnaire,OHRQL)对患者进行口腔功能和生活质量的评估。
治疗稳定性评估采用数字化技术对患者进行3年的追踪观察。
四、研究预期结果本研究预期结果是,正畸-正颌联合治疗成人骨性Ⅲ类错(牙合)能够达到显著的疗效,并且治疗效果稳定,不会出现复发情况。
同时,本研究还将提供正畸-正颌联合治疗成人骨性Ⅲ类错(牙合)的科学、可靠的治疗方案,为临床提供指导。

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).

而骨性Ⅲ类错颌是临床常见的骨源性畸形,患者多伴有下颌偏斜,咬合关系异常,面部为凹面型,双侧不对称且颏部向一侧偏斜是此类患者的共同特点,不仅影响容貌的端正和美观,还可引起语音、咀嚼等功能障碍及颞颌关节疾患[2]。
单纯正畸治疗仅可纠正轻度的骨性畸形,而骨性Ⅲ类错颌伴下颌偏斜患者需行正颌外科治疗,通过行上下颌骨截骨来调整上下颌咬合关系,这一点国内外临床已达成共识。
但术中分块截骨手术难度大,失血多,手术时间长,可能造成邻牙损伤甚至缺血性骨坏死等,而且术后易复发[3]。

Methods To select 30 cases of skeletal Class III malocclusion patients collected by the hospital from January 2016 to March 2018,all perform orthodontic and orthognathic combined treatment in the hospital.To evaluate the soft and hard tissue changes and the thickness of the alveolar bone in the anterior teeth before and after treatment,and to evaluate the quality of life. Results After the operation, the face and middle 1/3 ratio of the face is coordinated, the chin point is good, the lips are closed naturally, the temporomandibular joint has no tenderness, and the movement is no bounce.The chewing and swallowing functions are restored.The postoperative facial lobes and nasolabial angles were higher than those before surgery,the chin-labial angles were lower than before surgery, MP-SN and L1-SA were lower than before surgery, TLL' and TBs were higher than those before surgery, and DA, DSN, DUI and DUL' are higher than before operation, the difference is statistically significant (P<0.05). U1-SA,TSn, TUL', TPos before and after operation are compared (P>0.05).Postoperative UW, UW-m, UA, UP-m, LW, LW-m, LP, LP-m were lower than preoperatively, and LA was higher than preoperatively (P<0.05).Preoperative and postoperative UA-m, Comparison of UPand LA-M (P>0.05).The total OHRQOL score and the scores of each dimension were higher than that of the preoperative one month after orthognathic surgery (P<0.05),the total OHRQOL score and the scores of each dimension decreased after all treatments, and were lower than those before and after orthognathic surgery 1 month (P<0.05). Conclusion Patients with skeletal Class Ⅲmalocclusion received orthodontic treatment, with coordinated facial proportions, improved oral and jaw function, and improved soft and hard tissues after surgery. However, the thickness of the alveolar bone in the upper and lower anterior teeth will be reduced after the operation Therefore,clinicians should control tooth movement within a certain limit to reduce the loss of alveolar bone thickness.Key words: orthodontic orthognathic syndrome; skeletal Class Ⅲ malocclusion; anterior teeth area; alveolar bone thickness骨性Ⅲ类错牙合畸形患者主要表现为下颌前突或(和)上颌后缩,伴(或不伴)下颌偏斜;侧貌呈现新月形[1]。
正畸正颌联合矫治骨性Ⅲ类错牙合畸形疗效分析骨性Ⅲ类错牙合畸形是指上下颌之间的骨性关系存在异常,导致上下牙弓相互不配合,咬合关系不正常。
正畸正颌联合矫治是一种综合性的治疗方法,旨在通过正畸和正颌手术的综合应用,纠正骨性Ⅲ类错牙合畸形,恢复正常的咬合关系。
本文旨在分析正畸正颌联合矫治骨性Ⅲ类错牙合畸形的疗效。
正畸正颌联合矫治骨性Ⅲ类错牙合畸形是一种较复杂的治疗方法,其疗效受多种因素影响。
首先,病例选择是矫治成功的关键。
患者的骨性错牙合畸形必须达到矫治的指征,具备一定的骨骼生长潜力,且具备接受正颌手术的条件。
此外,患者的合作度和口腔卫生状况也会影响疗效。
如果患者合作度高,能够积极配合医生的治疗,同时保持良好的口腔卫生,那么治疗的效果会更好。
正畸正颌联合矫治骨性Ⅲ类错牙合畸形的疗程一般较长,通常需要2-3年的时间。
整个疗程分为正畸治疗和正颌手术两个阶段。
正畸治疗阶段旨在通过矫正器的力作用,调整牙齿的位置和咬合关系。
这一阶段的目标是使上下颌骨之间的错位得到纠正,为正颌手术提供良好的条件。
正颌手术阶段通常在正畸治疗完成后进行,主要通过手术的方式调整上下颌骨的位置和咬合关系。
手术通常包括上颌前突手术、下颌后缩手术等。
术后,患者需要在医生的指导下进行口腔护理和功能锻炼,以保证矫治效果的稳定。
矫治过程中的效果评估主要通过采用钱速器和其他矫治工具检测患者的咬合关系和牙齿的位置是否恢复正常。
同时,还可以通过X线片的比较观察骨骼的位置和错位情况。
一般来说,正畸正颌联合矫治可以有效地改善骨性Ⅲ类错牙合畸形的状况,使患者的咬合关系恢复正常,面容得以改善。
但是,每位患者的治疗效果有所不同,具体的疗效还需要根据个体情况来评估。
总的来说,正畸正颌联合矫治是一种应用广泛的治疗方法,可以有效地治疗骨性Ⅲ类错牙合畸形。
但是,疗效的实现需要患者的合作度和医生的操作水平等多种因素的综合作用。
通过全面评估和合理治疗,患者的咬合关系和面容可以得到有效地改善,提高患者的生活质量。
