【摘要】：目的：Delaire整体平衡头影测量分析法以患者个体颅颌面整体平衡结构为基准,构建适应于患者个体的理想的颅颌面结构,能够据此指导设计正颌手术方案。本研究分析由Delaire整体平衡头影测量分析法指导设计手术方案的重庆地区下颌前突畸形患者治疗后的效果及稳定性,为以后进一步临床推广奠定基础。方法：对20例重庆地区下颌前突畸形患者采用Delaire头影测量分析法设计外科治疗方案,于正颌治疗前、治疗后6-8个月及治疗后12-16个月进行Delaire头影测量分析及分析头颈姿势位变化情况,测量并统计分析18项Delaire头影分析项目及颅颈角NSL/OPT.NSL/CVT的变化情况。结果：1、下颌角点至颏下点距离(Go-Me)、下颌角点至下齿槽基座点距离(Go-LA)正颌治疗后无统计学意义上复发。2、实际下颌体平面与理论下颌体平面交角(∠Mp-F7)、实际咬合平面与理论咬合平面交角(∠Op-F8)正颌治疗后较治疗前显著减小。3、理想下颌角角度(∠F3-F7)、理想腭平面与理想下颌体平面交角(∠F4-F7)、理想下颌体平面与理想(?)平面交角(∠F7-F8)在3个时间点变化差异均无显著性意义。4、颅颈角NSL/OPT、NSL/CVT正颌治疗后较治疗前显著增大。结论：由Delaire整体平衡头影测量分析法指导下颌前突畸形外科正颌治疗术后后,患者颅颌面颈平衡结构根据新的颌骨形态作出适应性调整,无明显复发,具有相对稳定性,再次证明Delaire整体平衡头影测量分析法适合应用于骨性下颌前突畸形的正颌外科诊治,可进一步用以临床推广。
[Abstract]:Objective to construct an ideal craniomaxillofacial structure suitable for individual patients by using the general equilibrium cephalometric analysis method of the whole balance of the head and maxillofacial of the individual patients, so as to guide the design of orthognathic surgery.This study analyzed the effect and stability of the patients with mandibular protrusion malformation designed by Delaire balanced cephalometric analysis method in Chongqing area, which laid a foundation for further clinical application in the future.Methods: twenty patients with mandibular protrusion deformity in Chongqing were treated with Delaire cephalometric analysis.Delaire cephalometric analysis was performed 6-8 months after treatment and 12-16 months after treatment. The changes of head and neck posture were analyzed and 18 items of Delaire cephalometric analysis and NSL/OPT.NSL/CVT of craniocervical angle were measured and statistically analyzed.Results: 1, the distance from mandibular angle to submental point was (Go-Mean), and the distance from mandibular angle point to inferior alveolar base (Go-LAA) had no significant recurrence after orthognathic treatment. The angle of intersection between actual maxillary plane and theoretical maxillary plane was not statistically significant, and the actual occlusal plane was similar to that of theoretical maxillary plane.The theoretical angle of occlusal plane intersection is significantly lower than that before treatment. The angle of mandible is smaller than that before treatment. The angle of mandibular angle is the angle of angle between ideal palatal plane and ideal mandibular body plane (range F4-F7, ideal mandibular body plane and ideal mandibular body plane).There was no significant difference in the angle of plane intersection between the three time points. The craniocervical angle (NSLP / OPTN / CVT) increased significantly after orthognathic treatment.Conclusion: after orthognathic treatment of mandibular protrusion deformity, the craniomaxillofacial and cervical balance structure can be adjusted adaptively according to the new maxillofacial morphology by Delaire balance cephalometric analysis, and there is no obvious recurrence and relative stability.It is proved again that Delaire balance cephalometric analysis is suitable for orthognathic surgical diagnosis and treatment of osteomandibular protrusion deformity, and can be further applied to clinical application.
