ABSTRACT
Defects due to mandibulectomy often cause hard and soft tissue loss and result in esthetic problems and functional disorders such as mastication, swallowing, and pronunciation. After the mandibular reconstruction, several complications including loss of alveolar bone can cause limitations in maintenance or supporting of removable prosthesis. For these patients, implant-supported fixed restorations have been an appropriate prosthetic restorative method. In this case report, we report the patient who underwent mandibulectomy and mandibular reconstruction owing to oral cancer, and then restored the current dentition functionally and aesthetically by applying zirconia frameworks and monolithic zirconia crowns by computer-aided design and computer-aided manufacturing.

It is very hard for edentulous patients to satisfy retention and stability with their complete denture. Especially, for patients with systemic diseases such as Parkinson's disease causing involuntary and limited movements, fabricating complete dentures may be challenging to both dentists and patients due to functional limitations. To overcome this problem, overdentures can be used through conserving retained roots. In this case, a 45-year-old male patient had to extract numerous teeth due to dental caries, and at the time of visit he was taking drugs for diabetes and Parkinson's disease for a period of long time. A complete denture was applied to maxilla, and for mandible, an overdenture on two preserved retained roots was applied where its retention and stability were obtained by magnetic attachments. This case reports that overdenture with retained roots improved overall functional limitations.
