Cleidocranial dysplasia: Report of 4 cases and review

Oral Rehabilitation with Removable Partial Denture of a Patient with Cleidocranial Dysplasia

This case report describes the oral rehabilitation of a patient with cleidocranial dysplasia who received a removable partial denture along with silicone-based permanent soft liner to improve esthetic and masticatory function. This patient was the candidate of neither implant nor orthodontic treatment due to medical conditions, history of mandible fracture, age, and risk of fracture after mandibular teeth extractions. Cone-beam computed tomography has made it possible to obtain comprehensive information regarding the morphology and positional relationship of impacted supernumerary teeth. Also, proper collaboration between surgeon and prosthodontist helped to achieve significant improvements in patient's self-esteem, masticatory function, and esthetic.

Clinical and radiological findings in a severe case of cleidocranial dysplasia

Cleidocranial dysplasia (CCD) is a rare congenital autosomal dominant condition, causing hypoplasia of the clavicle, abnormal formation of teeth, skeletal and craniofacial bones. CCD is caused by the mutation of RUNX2/CBFA1 present in the short arm of chromosome 6 at position 21.1, a transcription factor essential for the formation of teeth, cartilage and bone. Patients with CCD show the classical features of excessive mobility of the shoulder bone, lack of resorption of the deciduous teeth, failure to erupt permanent teeth, multiple impacted and supernumerary teeth, and open fontanelle and sutures of the skull. In this article we report a case of CCD in a 16-year-old male patient, with an aim to highlight the clinical, radiological and recommended treatment guidelines.

Hypodontia and delayed dentition as the primary manifestation of cleidocranial dysplasia presenting with a diagnostic dilemma

Cleidocranial dysplasia is a rare autosomal disorder which manifests as partial or complete absence of clavicles, multiple supernumerary teeth, and delayed closure of fontanelle. Classical cases of cleidocranial dysplasia are easily diagnosed very early in the life. However, cases with partial manifestation of the syndrome and noncontributory family history are difficult to diagnose. Here, we report a case of 8.5-year-old girl child who presented with delayed tooth development (without any supernumerary teeth), anterior open fontanelle, and normal clavicles, thus resulting in a diagnostic dilemma.
