Anatomic assessment of palatal temporary skeletal anchorage devices insertion sites among patients with cleidocranial dysplasia vs controls: A retrospective cone-beam computed tomography analysis.

INTRODUCTION

Cleidocranial dysplasia (CCD) is a rare genetic skeletal condition characterized by underdeveloped clavicles and incomplete bone formation of the anterior fontanelle. Common dental complications of this condition include delayed eruption and the presence of multiple supernumerary teeth. This study aimed to compare palatal bone thickness among patients with CCD and a control group using cone-beam computed tomography.

METHODS

This study used cone-beam computed tomography to compare palatal bone thickness between patients with CCD and a control group. Seven patients with CCD and 59 controls were included, with palatal bone thickness assessed at various points.

RESULTS

Palatal bone thickness at all measured areas was consistently larger in the CCD group compared with the control group. Statistically significant differences (P <0.005) were observed in the following regions: anterior medial, anterior lateral, middle medial, middle lateral, posterior midline, and posterior lateral. The anterior lateral regions consistently exhibited the greatest thickness in the CCD group, aligning with findings in orthodontic patients without skeletal abnormalities.

CONCLUSIONS

Our investigation revealed the presence of sufficient palatal bone thickness among patients with CCD for temporary skeletal anchorage devices, with a trend toward increased values relative to the control group. Individual assessment of bone thickness is recommended because of individual variations. Using temporary skeletal anchorage devices may provide clinicians with a strategic approach to enhance orthodontic outcomes for patients with CCD.
