A fixed movable bridge is a type of fixed partial denture that is exclusively indicated where a lone standing abutment is situated between two partially edentulous spaces. The prosthesis design involves fabrication of two separate fixed partial dentures that are joined in one place with a non-rigid connector. Such design provides independent movement of two separate fixed partial dentures which may occur as a result of periodontal tooth movement of mandibular flexure. Most of the reported cases have been successfully designed in either posterior or anterior region. We present a case of a fixed movable bridge whose one component restored a missing anterior tooth and the other component a missing posterior tooth. With maxillary canine as a pier abutment, the challenges in designing included to place the non-rigid connector in a space that had two different angles in the horizontal plane. Another challenge was to provide an adequate thickness of the distal retainer without the retainer encroaching on the overjet and overbite of natural occlusion. This was successfully accomplished by preparing a rest seat that had different width and depth on the distal aspect as compared to the mesial aspect. The patient reported to be extremely satisfied with the design outcome for his complex partial edentulous situation.
