Dental treatment of patients with cleidocranial dysplasia: two case reports

INTRODUCTION: Cleidocranial dysplasia (CCD) is an autosomal dominant disorder, also referred to ascleidocranial dysostosis. The diagnosis is made on the basis of clinical and radiological findings and is confirmed through a genetic analysis. Cleidocranial dysplasia manifestations in the skeletal system include aplasia or hypoplasia of the clavicles, leading to shoulder joint hypermobility, a cone-shaped chest with short ribs, a wide skull with prominent frontal bone, etc. The dental status of CCD patients is commonly marked by a persistent primary dentition, delayed eruption of permanent teeth, supernumerary teeth, an incorrect proportion between the two jaws, impaired masticatory function and aesthetics.
