Abstract
Patient: A 56-year-old man presented with the chief complaint of difficulty in chewing caused by missing lower molars and the mobility of upper incisors. In this case, implant-retained porcelain-fused-to-metal prostheses were fabricated for the mandibular unilateral free-end space to reestablish proper occlusal support. For the upper incisal defect region, teeth-retained splinted porcelain-fused-to-metal prostheses were fabricated. The patient was followed for more than three years after treatment, and a slight chipping of porcelain was observed in the prosthesis of the lower-left second molar during the follow-up period. The chipping was treated by surface modification and polishing of the surface.
Discussion: The vertical shear stress caused by occlusal interference at the time of mandibular front exercise, due to the metal frame being small, is considered to have caused the chipping.
Conclusion: Functional problems caused by loss of occlusal support were successfully rehabilitated using implant-retained fixed partial dentures.
