An investment method is described for fabrication of a closed hollow obturator based on the use of three sections of a denture processing flask. The thickness of the obturator portion is minimized and all surfaces exposed to the oral cavity are processed with heat-polymerized acrylic resin. The technique eliminates additional steps noted in the literature, allowing for the prosthesis to be processed to completion from the wax trial denture. This technique provides a lightweight and seamless obturator and can be used for complete or partially edentulous cases. Clinical and laboratory time are minimized while fabricating a durable, virtually water-tight prosthesis that can be used alone or in conjunction with an extraoral prosthesis.
描述了一种基于使用义齿加工盒的三个部分来制造封闭中空阻塞器的投资方法。阻塞器部分的厚度被最小化，并且所有暴露于口腔的表面都用热聚合丙烯酸树脂进行处理。该技术消除了文献中提到的额外步骤，使得假体能够从蜡型试戴义齿加工完成。该技术提供了一种轻便且无缝的阻塞器，可用于全口或部分无牙的病例。在制造耐用、几乎防水的假体时，临床和实验室时间被最小化，该假体可单独使用或与口外假体联合使用。
