Mandibular denture constructed using piezography for mandibular defect with scar contraction

Abstract

Patient: The female patient, who was 55 years old at the time of treatment, was suffering mandibular gingival cancer. Resection of the following parts was necessary: right hemilingual, right margin of the mandible, from the right mandibular lateral incisor to the 6th tooth of the second molar, and the buccal mucosa. Restoration of these resected parts was performed by using a forearm flap.

Discussion: Application of piezography allowed us not only to arrange the positions of the artificial teeth but also the denture base morphology in the surrounding tissue of the defective jaw and the buccal mucosa associated with scar contraction. It was also considered that the FGP technique established adequate contact during jaw engagement.

Conclusion: In this case of restoration of a jaw defect by using a forearm flap, the use of piezography and the FGP technique enabled us to produce a denture for the defective jaw, resulting in a good prognosis.
