Dental treatment of patients with cleidocranial dysplasia: two case reports

Abstract

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. AIM:The aim of the present study is to show the clinical and radiologic findings of two CCD patients and describe the multidisciplinary approach necessary for their treatment. Early diagnosis and awareness of the condition help to determine the optimal treatment and duration as well as to improve patients' quality of life. CASE REPORT:The subject of this clinical study are two closely related patients who sought professional dental help due to persistent primary teeth, delayed eruption of permanent dentition beyond the mean eruption age and resultant occlusal and aesthetics problems. RESULTS: Correction of the dental status in CCD patients is a long process. Timely combination of orthodontic and surgical treatments is crucial for optimal and long-lasting results.CONCLUSION: Dental treatment of CCD patients is a complex endeavor. The type of approach in the orthodontic, surgical and prosthetic treatment is largely determined by the patients' age, their general health as well as their intraoral status (present deciduous teeth, existing permanent teeth and occlusal contacts).
