Abstract
Cleidocranial dysplasia(CCD) is a congenital genetic disorder of skeletal and dental abnormality, which is mesodermal dysfunction influencing many tissues and organs, CCD was reported by Morand at first in 1766, And later, it was named cleidocranial dysostosis, cleidocranial dysplasia, Marie-sainton syndrome and mutational dysostosis. It is autosomal dominant disorder and there is no prevalence between man and woman. Until recent days, mutation of Runx2 in chromosome6p21 has known to be a main factor causing CCD. The specific clinical features of CCD are aplasia or hypoplasia of one or both clavicles and incomplete closing of fontanels and cranial sutures. Dental manifestations include retention of deciduous teeth, delayed eruption of permanent teeth, supernumerary teeth and cyst. Because there is no mental retardation and physical disability in CCD patients, they usually can not recognize their dental abnormality by the time of abolescence. So, after exfoliation of deciduous teeth, they usually live with edentulous status. It usually drives CCD patients to suffer from esthetic and functional problem. For this reason, CCD patients must be early diagnosed and improved in their appearance as well as masticatory function. So, surgical removal of supernumerary teeth and orthodontic eruption of the natural permanent teeth at adequate time is necessary.
치과의사는 쇄골두개 이형성증의 특징에 대해 잘 알고 있어야 한다. 쇄골두개 이형성증 환자는 신체 및 정신적으로 특별한 이상을 보이지 않기 때문에, 영구치교환시기를 한참 지나 다수치아에서의 유치만기잔존 및 영구치의 미 맹출을 주소로 치과에 내원하게 되는 경우가 많은 것이 사실이다. 이런 의심이 들 때는 정확한 진단을 위해 반드시 다양한 방사선사진을 촬영해 보아야 하겠다. 또한 긴 치료기간으로 인해 환자의 협조와 여러 분야에 있어서 전문가들의 협력이 반드시 필요할 것이다.
