A new type of highly resilient retainer for maxillary obturator prostheses is described. The obturator component is composed of an acrySic 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.
