A Case Report of Maxillofacial Prosthesis on 7 Cases

As compared with general prosthodontic treatment, maxillary prosthetics is difficult to make a plan, treatment, and postoperative control, so that it has large defects and denture bearing area decreases, the changing quantity of defective bone is large is the course of time. This time we experienced the 7 cases of disease (4 upper cases, 3 lower cases) including 5 cases by tumour, 1 case by trauma, and 1 case by cyst. In case of maxilla, we treated on prosthodontics after radical operation, in case of mandible, we made it after radical operation, recover operations for example implantation for iliac bone dermatoplasty. As shown under, we know that conclusions we cured defective parts of bomy structured by obturator in case of maxilla chiefly we use the system of bar clasp for remained teeth to make maintenance and stability. In aim of support, we used flange technique to improve border molding, and used Levin's bladed metal teeth to relieve the mucous charge's quantity by force of bite and keep out of eccentric moments. Meanwhile, it is difficult for mandible to recover by denture in case of having the missing bomy parts. Therefore we made prothesis, after implantation of iliac bone, and dermatoplasy, improvement of discrepancy as well as we could in mandible. The plan of plate in the case like this was carried out, not only in the view of anatomy, but also in the point of dynamics to disperse force of bite well and balance square of implantations with original own jaw's bone. And in case which we experience so that we could use residual teeth, we use Dolder's bar attachment in order to be lower the point of force and splint of residual teeth for retainer of denture. The prognosis of all cases were improved on physiologic functions and esthetics. Especially the 7th cases, though it passed ten years after having denture, the mobility of abutment teeth resorption of transplantationed bone can not be observed and oral hygene condition is good and make various physiologic functions.
