Histological examination and clinical evaluation of the jawbone of an adult patient with cleidocranial dysplasia: a case report.
OBJECTIVE
Cleidocranial dysplasia (CCD) is a rare congenital malformation syndrome, inherited autosomal-dominantly. During a course of treatment including surgical, implantological and restorative procedures, an opportunity arose to histologically examine biopsies of the maxilla and mandible of a CCD patient 47 years of age.


METHODS
The aim of this case report is to present the results of the histological evaluation of the alveolar bone and the surgical pretreatment for and placement of six implants each in the maxilla and the mandible. The implants were inserted in a minimally invasive procedure using 3D template guidance. Following uneventful healing of the implants, ceramically veneered bridges were cemented on individual titanium abutments. Since the patient had not received orthodontic treatment in childhood-which would have been the treatment modality of choice-this implantological and prosthodontic approach was necessary. Biopsies were taken from the maxilla and the mandible before placing the implants. Histological evaluation showed bone with strong, coarsely interconnecting trabeculae, especially in the maxilla. Both the bone and the gingiva otherwise exhibited a normal structure without pathological features or anomalies.


CONCLUSIONS
The clinical parameters and histological evaluation of this one clinical case suggest that the concepts familiar from general oral implantology in terms of surgical and prosthetic procedures can be adopted for older patients with CCD.
