術者可撤式補綴物から患者可撤式補綴物へ設計変更した症例について

抄録

There was a case with a screw-retained retrievable prosthesis connected with remaining teeth. The patient complained of severe pain and food impaction around implants while eating. Two IMZ implants have been placed at missing frontal teeth. Two implants were not removed because there was no percussion pain and spontaneous pain and X-ray indicated no bone loss around the implant.Implants were connected with each other by a new CM-bar. The detachable prosthesis retained with the bar and clip attachment was connected semirigidly with the remaining teeth. Pain and food impaction decreased.
In this case, the rigid connection with the remaining teeth brought about an unexpected moment,which caused the pain around the implant while eating.
