A new type of highly resilient retainer for maxillary obturator prostheses is described. The obturator component is composed of an acrylic resin connector and a round resilient wing, with the combined shape resembling a mushroom. The retainer is designed to absorb mechanical stresses, which are transmitted from the denture portion to nasal soft tissues through the obturator extension, and to use tissue undercuts more effectively than do conventional hollow extension prostheses. Renewability of the retainer part is another advantage of this retainer. From these properties, the retainer seems to have many indications for the prosthodontic treatment of maxillary defects.
本文描述了一种新型的用于上颌阻塞器假体的高弹性固位体。阻塞器组件由丙烯酸树脂连接器和圆形弹性翼组成，其组合形状类似蘑菇。该固位体旨在吸收机械应力，这些应力通过阻塞器延伸部从义齿部分传递到鼻腔软组织，并且比传统的中空延伸式假体更有效地利用组织倒凹。固位体部分的可更新性是这种固位体的另一个优点。基于这些特性，该固位体似乎在上颌缺损的修复治疗中有许多适应证。
