| 内容記述 | The number of patients with impacted teeth is increasing. We investigated the relationship between impacted canines and jawbone growth and development. Panoramic and lateral cephalometric radiographs of 80 patients with malocclusion involving impacted maxillary canines were analysed and classified using sector and McSherry and Pitt et al.’s classifications. Sella turcica bridging and ponticulus posticus formation were studied to assess the relationship of growth and development with impacted maxillary canines. Bone age was assessed by Baccetti’s cervical vertebral maturation stages. Classes I, II and III sella turcica bridging occurred in 48.7%, 47.5%, and 3.8% of the cases, while ponticulus posticus classifications occurred in 82.5%, 12.5%, and 5% of cases, respectively. Cervical vertebral maturation stages were one stage lower than chronological age. Although the chronological age and the positional assessment of the impacted canines were correlated positively with the sector classification and McSherry and Pitt et al.’s classification for Classes 1 and 3, they correlated negatively for Class 2. The trend in bone growth delay correlated negatively with the distribution in McSherry and Pitt et al.’s Class 2. Assessing cervical vertebral maturation stage, sella turcica bridging, and the ponticulus posticus formation may facilitate early diagnosis of impacted canines, and could facilitate future orthodontic treatment. | |||||
