热塑膜片式暂时性赝复体修复硬软腭缺损9例

Thermoplastic temporal prosthesis in repair of hard and soft palate defects in 9 cases

Etrotic公司生产的热塑型膜片(ERKOLODC-pro,595115),可在真空加热加压状况下根据牙弓形态成形,提供良好的固位和阻挡作用。对2006-09/2007-01解放军总医院口腔科收治的拟因切除肿瘤造成的硬软腭联合洞穿型缺损,需进行即时阻塞修复的9例患者,以热塑型膜片制作设计暂时性赝复体,厚度为1.5mm,并根据患者的牙周状况选择不同类型的膜片。患者初戴后有不适感1例,为缺损软腭部分较多者,基托靠咽近者,适应1周后恶心反应消失。3例疼痛均因局部创口边缘软组织水肿,基托压迫,经调整后疼痛消失。结果显示,热塑膜片材料与宿主无生物相容性不良反应,所设计的暂时性赝复体可封闭鼻腔,使硬软腭缺损患者的吞咽功能和发音功能均得到恢复。

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 l 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.
