PATIENT A 55-year-old female patient was treated with a removable partial denture for the mandibular bilateral free-end space. Since the patient did not wear the removable partial denture because of discomfort, the remaining teeth were mobile. She also complained of temporomandibular joint pain on both sides. Implant therapy was planned for the mandibular bilateral free-end space to reestablish the proper occlusal support. DISCUSSION After setting the implant restorations for the mandibular bilateral free-end space, mobility of the remaining teeth and temporomandibular joint pain disappeared. During the observation period after treatment, no biological and biomechanical problems appeared. CONCLUSION Implant therapy is effective not only for establishing the occlusal support but also for re-establishing the stability of remaining teeth.
