Masticatory function was analysed before and after orthodontic treatment in two cases where tooth alignment remained unusual after treatment. The Sirognathograph Analyzing System® was used to analyse the masticatory function. In both cases, the right maxillary first premolar was located where the maxillary canine is normally positioned. The results of orthodontic treatment were satisfactory both morphologically and aesthetically, and masticatory function was greatly improved. However, some problems remained in the mandibular movement due to the abnormal contact between the mandibular teeth and the maxillary first premolar. These findings support the need for examination of masticatory function when treating patients with an unusual tooth alignment even if the results of orthodontic treatment are both morphologically and aesthetically successful.
