    Abstract

    Double crown prostheses can be used in patients who have a few remaining teeth and poor periodontal condition because of secondary splinting of abutments, vertical loading, decrease of the length of lever arm due to fulcrum line located on margin of inner and outer crown. Successful results of treatments using double crown prostheses for the partially edentulous patients who have a few remaining teeth and implant overdenture using a small number of implants have been reported. In this case, there were a few remaining teeth with a very poor periodontal condition in maxilla, and there were a failed implant with severe alveolar bone resorption and shrinkage in the mandible. The main objective of this report is to introduce our case because a double crown partial denture showed satisfactory results in functional and esthetical aspects during more than one-year follow-up period.
