An overdenture is a prosthesis that supplies support from one or more abutment teeth by covering them beneath its mucosal surface. Different kinds of attachment systems, which are constructed on existed abutment teeth are used to increase the retention and stability of the denture. Schubiger attachment design is one of the attachments, which consists of prefabri- cated screws to connect the abutment teeth to bar retainers. This report presents the rehabilitation of a partially edentulous case with teeth supported over- dentures in which modified Schubiger attachment design was used instead of its prefabricated form.

A 31-year-old male patient reported with the chief complaint of many missing teeth in our Department of Prosthodontics. The patient’s history revealed missing teeth due to periodontal disease. Intraoral examina- tion revealed that remaining teeth were located in cross arch as an advantage in stabilization (#13, #21, #23, #26, #27, #33, #37, #43, #45), but the height of the clinical crowns were so high to rehabilitate by a conventional removable partial denture. All situations were discussed with the patient and an overdenture treatment plan was choosen for both having the ideal esthetic, function and preventing the loss of alveolar bone for possible implant supported fixed prosthesis rehabilitation in the future. Thus, both preventive treatment on existing bone and cost effective treatment to the use of prefabricated attachments were obtained. The applied treatment met the patient’s needs such as esthetic and function.
