Mandibular unilateral free-end missing reconstructed by implant prosthesis

PATIENT: A 58-year-old woman presented with a chief complaint of masticatory dysfunction caused by the missing of lower right molars and the detachment of fixed partial denture at the upper right molar region. For this case, implant-retained fixed partial denture with hybrid ceramics facing cast crowns for lower right molar region and conventional fixed partial denture for upper right molar region, considering both the secondary caries and the extrusion of upper right second molar, were fabricated. The patient was followed for >4 years after treatment, and separation between mandibular implant prosthesis and the lower right second premolar was observed during the follow-up period. The interdental separation was treated by refabrication of the prosthesis of the second premolar. DISCUSSION: Physical teeth movement may cause separation between natural tooth and implant-retained prosthesis. CONCLUSION: Functional problems caused by the loss of occlusal support were successfully rehabilitated using implant-retained fixed partial denture.
