造成错畸形的病因是多方面的。从形态上来看,既有上、下颌骨,牙弓,牙量,骨量的不调,也有属于上、下牙弓中相对应的牙齿大小的比例关系失调而造成的。对前者国内外已有很多论述发表,而后者国外在这方面研究很早就开始了,国内尚未见到这方面的调查资料。为了提高诊断水平,正确制定治疗设计,我们根据Bolton的方法,对上海地区85例恒牙前期正常(牙合)儿童进行了测量分析。充实了临床病因分析和诊断,并对治疗的设计和方法有一定的指导意义。
The cause of malformations deformity is multifaceted. From the morphological point of view, both on the mandible, dental arch, tooth volume, bone mass is not adjusted, but also belong to the upper and lower dental arch corresponding to the size of the tooth size imbalance caused. There have been many expositions on the former at home and abroad, and the latter has been started very early in this field in foreign countries. The survey data in this respect have not yet been seen in China. In order to improve the diagnostic level and to design a proper treatment design, we measured and analyzed 85 pre-natal normal occlusion children in Shanghai based on the method of Bolton. Enrich the clinical etiology analysis and diagnosis, and treatment of the design and methods have some guidance.
