Long-term alveolar bone resorption in edentulous patient causes difficulty in denture use. Applying an implant overdenture with 2 to 4 implants to edentulous patient is easily approachable. Moreover, it improves denture stability, support, and retention. Milled bar, the attachment used in implant overdenture, can be used to induce better stability and retention to the supporting structure than conventional bar. It has become convenient to use due to the development of CAD/CAM system which had allowed the simplification of dental techniques. In this case, application of conventional maxillary full denture and mandibular overdenture made of CAD/CAM milled bar with 4 implants showed satisfactory results in the patient who had used upper and lower full dentures for a long time.

Overdenture using dental implants could improve the problems of conventional complete denture function which are pain during mastication, insufficient retention and stability. Locator attachment used widely for implant-retained overdenture has advantages that it needs the smallest vertical space and also its nylon male cap allows personalized retention for each case. However its retention force decreases rapidly with function rather than the bar and ball attachment. So, implant fixture should be positioned as parallel as possible.

Rehabilitation of maxillectomy patients is challenging. The maxillary defects need to functional restoration because of mastication, speech, swallowing problems. The goal of making obturator is to restore maxillary defects and give patients comfortable, esthetic prosthesis. This case report presents acquired masticatory and esthetic results and improved retention resulting from the pharyngeal obturator prosthesis using implant.

Overdenture is one of the methods of patients with severely worn dentition. Remaining natural teeth help preserve alveolar bone and proprioception and provide rigid support. Also, overdenture distributes the concentrated stress applied to the abutment tooth and denture supporting tissues. There is an advantage that it can provide long-term stability to denture. In this case, the patient with only a few teeth due to severe wear and caries was satisfied with good function and favorable esthetics by using overdenture.

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.
