Thermoplastic temporal prosthesis in repair of hard and soft palate defects in 9 cases / 中国组织工程研究

ABSTRACT

Etrotic Company produced thermoplastic diaphragm (ERKOLODC-pro, 595115) can be shaped according to dental arch form under vacuum heating pressure, resulting in good fixation and baffle effect. Nine cases with soft and hard palate defect caused by tumor, who needed the repair of temporal obturator prosthesis made by thermoplastic diaphragm (1.5 mm of thickness), were selected in this study at the Department of Stomatology, General Hospital of Chinese PLA from September 2006 to January 2007. Different diaphragms were used according to periodontal status. Only one case with more soft palate defect felt naupathia when wore this kind of denture near throat. After 1 week, the uncomfortable feeling disappeared. Three patients felt pain, and the main reason is tissue dropsy around wound entry and denture crackdown. After grinding, pain disappeared. This indicated that no adverse reaction in biocompatibility was detected between thermoplastic diaphragm and host. Temporal prosthesis can improve swallowing and voiced function of soft and hard palate defect patients by closing nasal cavity.
