上顎切除と同時にエピテックシステムを用いて即時顎補綴治療を行った1例 Immediate prosthetic maxillary reconstruction using an Epitec System after maxillectomy : report of a case
It is difficult to restore function by conventional maxillary prosthetic treatment in patients with extensive maxillary defects after cancer ablation. Early functional rehabilitation was attempted by the immediate installation of prostheses supported with an Epitec System after maxillectomy for a malignant maxillary tumor.<BR>Before surgery, a stereo-lithographic model of the patient's skull was fabricated on the basis of preoperative CT data analysis, and the region occupied by the tumor was removed from the skull model for presurgical simulation. An Epitec plate was bent and bilaterally fixed to the remaining zygoma bones and the anterior wall of the maxillary sinus to cover the defects in the maxillary alveolar ridge and palate on the skull model. An immediate maxillary prosthesis was also prepared at the same time.<BR>A sterilized Epitec plate was fixed to remaining bone with screws immediately after tumor resection, and mushroom-type abutments were connected to the plate. An immediate maxillary prosthesis was placed at the end of surgery.<BR>An Epitec System proved to be highly effective for supporting an immediate prosthesis in a patient with a large maxillary defect.
