Abstract:
1. A method of fitting a resiliently lined rigid prosthetic denture, of the type removably secured to permanently implanted dental support posts embedded into a patient's jaw, where the support posts each include a shank secured into the patient's jaw and a head portion extending outwardly longitudinally from the shank and beyond the patients jaw surface, the head portion comprising a neck extending outwardly above the jaw surface and a cap secured to the outward end of the neck portion and extending from the neck portion, the cap is of a generally elongated, or ellipsoidal shape from a top view the method comprising the steps of: molding a denture prosthesis foundation, to form a dental prosthesis, including a concave under surface intended to fit over and around the jaw ridge, the foundation being formed from a relatively hard dental resin, the hard dental resin defining the concave portion being formed to provide space for the insertion, and the molding, of a softer, more resilient dental resin liner within the concave portion, the molding being carried out on a form selected from the patient's jaw ridge or a molded form made of the patient's jaw ridge, the form including the head portion and caps of each implanted post in the mouth of the patient, inserting a curable, softer, more resilient dental resin into the concave portion, removably placing the denture foundation containing the curable, softer, more resilient dental resin, onto the form, and allowing the curable resilient resin to cure and set, so as to form a suitable seal between the cured resilient resin and the sides of the jaw ridge and around the caps, resulting in a removable but sealably secure denture in the mouth of the patient.
