Abstract

As an evaluation of treatment for anterior crossbite (Class I Malocclusion) in the mixed dentition, relationships were examined between the results of cluster analysis on the measured values before treatment and those on the changes caused by treatment. The following were the results of the present investigation. 1. The results of cluster analysis on the measured values before treatment were summed up into three groups; A1, A2, and A3. 1) Group A1 showing retrusion of the Maxilla and lingual version and lingual inclination of Maxillary anterior teeth. 2) Group A2 showing protrusion of the Mandible, lingual version of Maxillary anterior teeth, and lingual inclination of Mandibular anterior teeth. 3) Group A3 showing lingual version of Maxillary anterior teeth and labial version of Mandibular anterior teeth. 2. The results of cluster analysis on the changes caused by treatment were classified into three groups; V1, V2, and V3. 1) Group V1 showing labial version and labial inclination of Maxillary anterior teeth and lingual version and lingual inclination of Mandibular anterior teeth. 2) Group V2 showing protrusion of the Maxilla, labial version of Maxillary anterior teeth, and lingual version and lingual inclination of Mandibular anterior teeth. 3) Group V3 showing retrusion of the Mandible and labial version and labial inclination of Maxillary anterior teeth. 3. Relationships between Groups A1, A2, and A3 and those of V1, V2, and V3 may be summarized in the following. 1) Group A1 shows healing trend of Group V2. 2) Group A2 shows healing trend of either Group V1 or Group V3. 3) Group A3 shows healing trend of Group V1. The results shown above indicate that healing process is dependent upon many factors including a problem of mixed dentition, a problem of constructing dental arch and individual growth characteristics. Therefore, it is important for us to recognize the findings described above when treating anterior crossbite in the mixed dentition.

[混合牙列前牙合治疗效果评价]。

作为对混合牙列前十字牙合(I类错牙合)治疗的评价，对治疗前测量值的聚类分析结果与治疗后变化的关系进行了检验。以下是目前调查的结果。1. 对治疗前的测量值进行聚类分析，将结果分为三组;A1 A2 A3。1) A1组为上颌前牙的上颌后缩、舌侧伸和舌侧倾斜。2) A2组为下颌前突，上颌前牙舌型，下颌前牙舌侧倾。3) A3组为上颌前牙舌型和下颌前牙唇型。2. 聚类分析结果将治疗引起的变化分为三组;V1, V2, V3。1) V1组上颌前牙唇型和唇倾，下颌前牙舌型和舌倾。2) V2组为上颌骨前突，上颌前牙唇型，下颌前牙舌型和舌倾斜。3) V3组为上颌前牙下颌骨后缩、唇型及唇倾。3.A1、A2、A3组与V1、V2、V3组之间的关系概括如下:1) A1组显示V2组的愈合趋势。2) A2组V1组和V3组均有愈合趋势。3) A3组呈现V1组愈合趋势。上述结果表明，修复过程取决于许多因素，包括混合牙列问题、牙弓构建问题和个体生长特征。因此，在治疗混合牙列的前牙合时，认识到上述发现是很重要的。
