Oral implant therapy for a patient with congenital anodontia and prolonged retention of deciduous teeth

Abstract

Patient: A 30-year-old female visited our hospital with chief complaints of chewing difficulty and esthetic problem. She was not satisfied with a removable partial denture for a defect caused by congenital partial anodontia, and selected oral implant therapy. Deciduous teeth with a poor prognosis were extracted, and the implant body was installed with bone augmentation because of limited bucco-lingual bone width. After the establishment of anterior guidance with provisional restorations, all-ceramic crowns of the implant lever were set as the final superstructures.

Discussion: The width of the jaw bone might be caused by anodontia. As the mucosa over the residual ridge was thin, veneer grafting was selected as a hard tissue augmentation procedure rather than the GBR to avoid fenestration of oral mucosa.

Conclusion: Oral implant treatment with bone augmentation was effective for this patient with partial anodontia and prolonged retention of deciduous teeth.
