Abstract：
Prosthetic rehabilitation of a partial or total maxillectomy with an obturator is the most acceptable treatment option. The hollowing of the obturator prosthesis is beneficial as it reduces the stresses over the underlying and surrounding tissues. A simple technique of fabricating a hollow bulb obturator has been discussed in this article. At the step of the packing of a denture, the hollow wax pattern of the defect area is formed with modeling wax. This hollow wax pattern is filled with water and is allowed to freeze to form an ice block. This ice block is removed from the wax pattern and is interposed between two layers for heat-cured acrylic resin and is then cured. After processing the denture, the water is retrieved by making a small hole in denture base, which is packed after hollowing with a cold cure acrylic resin. A lightweight prosthesis with a uniform thickness was achieved with a readily available and easily retrievable material, i.e., ice.
摘要：
用闭塞器进行部分或全部上颌骨切除术的修复康复是最可接受的治疗选择。闭孔假体的空化是有益的,因为它减小了下层和周围组织上的应力。本文讨论了一种制造空心灯泡闭塞器的简单技术。在包装假牙的步骤中，缺陷区域的中空蜡形图案由造型蜡形成。该中空蜡模填充有水并允许冷冻以形成冰块。将该冰块从蜡模中取出并插入两层用于热固化丙烯酸树脂的层之间,然后固化。加工假牙后，通过在义齿基托上打一个小孔来回收水，它是用冷固化丙烯酸树脂中空后包装的。用容易获得且易于取回的材料实现了具有均匀厚度的轻质假体，即，冰。
