Dentin dysplasia type I treated with onlay bone grafting, sinus augmentation, and osseointegrated implants.

[dentin dysplasia]

Dentin dysplasia is a defect of dentin development that was classified by Shields as type I and type II . The teeth in dentin dysplasia type I are characterized by normal enamel and abnormal dentin in the crown and root . For that reason , this disorder is characterized by dental caries , early exfoliation of the teeth and , consequently , maxillomandibular bony atrophy . In this report , we present a case of a young girl affected by dentin dysplasia type I , treated with a combination of onlay bone grafting and a sinus lift technique to accomplish implant placement . This case showed that onlay autogenous grafting and a sinus lift technique are well-tested methods of bony augmentation and can be useful in patients with congenital dentin defects , such as dentin dysplasia .
