The purpose of the present study was to investigate malformation of the maxillae in seven congenitally prognathic AGU (Aichi-Gakuin University) six month old beagles. Dimensional analysis was done on cephalograms and dental casts. Analysis used 26 reference points on cephalograms and 81 points on casts.The study revealed the following :1. the mandible showed lateral shifting (four animals showed left shifting and three showed right)2. the amount of shifting to the left was larger than that to the right3. this mandibular shifting was not limited to the dental arch but the mandible itself also was malformed4. this malformation was not limited to the mandible but the maxillae were also affected5. in one animal, a total of five teeth were congenitally missing in both arches, and in another animal, two teeth were congenitally missing but only in the lower arch. Cephalometric dimensional data were established for normal and congenitally prognathic AGU-strain beagle dogs at six months of age.

本研究的目的是调查畸形的上颌骨在七个先天性下颌骨AGU（爱知学院大学）六个月大的比格犬。对头颅X线片和牙模进行了尺寸分析。分析了26个头颅X线片参考点和81个石膏模型参考点。下颌骨出现侧向移位（4只动物左移，3只动物右移）。左移量大于右移量3。这种下颌骨移位不仅限于牙弓，下颌骨本身也存在畸形4。这种畸形不仅限于下颌骨，上颌骨也受到影响5。在一只动物中，两个牙弓中总共有五颗牙齿先天缺失，在另一只动物中，两颗牙齿先天缺失，但仅在下牙弓中。
