Abstract
In cases of malocclusions in a growth phase, it is necessary to start orthodontic treatment based on the growth prediction, in order to avoid a recurrence and extension of the treatment period. A number of studies using cephalograms have been reported, but precision to enable predictions and ease of operation are the key in clinical context. This article aims to explicate examination on the growth prediction and degree of difficulty of the treatment by overlaying lateral cephalograms of six patients with malocclusion on Sakamoto-based profilograms and observing positions of the condyles and backward and forward positions of the maxillary. As a result, the crossbite cases in a growth phase show better stability when the condylar position is close to the average (according to Sakamoto-based profiograms), but tend to be less stabile when the mandibular condyle was located forward and the maxillary located backward compared to the average. In the aspect of the growth prediction, a technique to link individual morphological characteristics appeared in the cephalogram with a future image is deemed useful.
