涉及先天缺牙与错(牙合)关系的文献还不很多,现将笔者通过X线摄片证实的43例先天缺牙错(牙合)病员模型的分析结果报道如下。资料分析一、缺牙数目:43名缺牙者共缺牙110个(不包括第三磨牙,下同),人均2.6个。16名男性缺牙52个,人均3.3个,占缺牙总数47.3%;27名女性缺牙58个,人均2.2个,占缺牙总数52.7%。缺牙总数在4个以下者39名,6个以上者4名。 There are not many literatures on the relationship between congenital and occultation and occlusion. Now we report the results of the analysis of 43 cases of congenital and occult occlusion by X-ray. Data Analysis First, the number of missing teeth: 43 missing teeth were 110 teeth (excluding the third molars, the same below), 2.6 per capita.
