The mandibular reconstruction by using Dacron-Urethane prosthesis, costchondral graft, fresh autogenous marrow & cancellous bone chips and kirschner's wire was performed on the 20-year-old female whose left hemimandible was diagnosed as central hemangioma and was resected at of 8-years of age. The satisfactory results were obtained from both esthetic and functional aspects.The operative procedure by using Dacron-Urethane prosthesis after Schwartz has many advantages not seen in other procedures. We suggest that this procedure should be employed in such cases as the large defect of the mandible or defected parts of the mandible are hard to be reconstructed.

A prosthetic treatment of maxillary protrusion should be indicated, when the patient is old, or anterior teeth of upper jaw cannot be preserved.For many years, removing the external labial of bone was practiced in such a case.However this method has disadvantages of lowering the alveolar ridge and sometimes causing undercuts with passing time, because the postoperative bone resorption is excessive and irregular.We performed intraseptal alveolectomy (Dean's technique) for the prosthetic treatment in 5 cases, and satisfactory results were obtained in all cases.We consider that this technique based on biological princioles has some advantages as follows:1) Postoperative inflamation is slight, because the labial periost and the muscle attachment are not disturbed.2) As the periodontal membrane is preserved, healing is rapid.3) As the labial cortical plates of bone is preserved as a vital onlay bone graft with intact blood supply, postoperative resorption is minimized, and the shape of alveolar ridge is rarely changed.4) This technique lends itself well to immediate denture surgery, and needs no rebase for final denture.5) We can mold the alveolr ridge into the desired contour during operation.6) This technique is a simple dental surgery which can be done in an outpatient room under local anesthesia.

We experienced a case of total resection of mandible for subacute suppurative osteomyelitis in a 25 year old man.As an extensive area of right mandible already was found to have been destroyed at first examination, resection of affected side was indicated.But, inflamation developed to the residual left side of the mandible and diffused bone destruction rapidly extended to the ramus of the mandible.About 1 year after hemimandibulectomy we had to completely resect the mandible.About 3 years after hemimandibulectomy we carried out secondary total reconstruction with iliac bone grafting and AO metal plate.Then 5 years after hemimandibulectomy we performed mandibular vestibuloplasty with inlay skin grafting which enabled the patient to accept a full denture.

Nodular fascitis is an unusual, tumor-like, proliferative, fibroblastic lesion with infiltrative properties. We describe a case of nodular fascitis appearing in the mandible of a 2-year-old boy. A brief review of the literature on this lesion arising from intra or perioral regions, and the importance of differential diagnosis for this lesions are discussed.
