Titanium Screw Anchorage for Traction of Many Impacted Teeth in a Patient with Cleidocranial Dysplasia

Introduction: Cleidocranial dysplasia (CCD) is a rare inherited skeletal dysplasia, often with prolonged retention of deciduous teeth and several impacted permanent successors and supernumerary elements.

Methods: This article demonstrates the usefulness of titanium screws for orthodontic anchorage to induce eruption of the impacted teeth in a patient with CCD. A boy, aged 10 years 11 months, had a number of impacted permanent teeth. After the supernumerary teeth were extracted and the incisors were surgically exposed, 2 titanium screws were placed in the palate without incisions or flap surgery. After implantation, a lingual arch appliance was placed, and orthodontic load began 4 weeks after surgery with an elastic chain.

Results: After 4 months of traction, 3 impacted incisors had erupted into the mouth.

Conclusions: This new method for retraction of impacted teeth can reduce the patient's treatment time and psychological stress. Treatment with titanium screws for traction of impacted teeth might be a new treatment strategy for managing CCD patients.
