Replacing an Implant-Retained Overdenture with Four Locator Abutments with a Handcrafted Polyceramic TRINIA® Telescopic Prosthesis on Four Universal Abutments with Four Milled Retentive Copings in Only Two Restorative Visits

Posted on by Bicon

This treatment demonstrates the clinical and laboratory aspects for the fabrication and insertion of a handcrafted polyceramic TRINIA® telescopic restoration on four unmodified Universal Abutments with four milled retentive copings to replace an implant-retained overdenture with four Locator Abutments for an eighty-four-year-old man, who was not satisfied with his Locator retained prosthesis. During the first clinical visit, after the clinical evaluation and consult, the patient’s four Locator abutments were removed and a full arch implant-level transfer impression was made along with a tooth shade and an initial occlusal registration, for the fabrication of a Gothic Arch plate and stylus. Subsequent to the fabrication of the Gothic Arch devices, a second occlusal registration was made and the patient’s existing Locator abutments were reinserted prior to reinserting his existing overdenture. During the second clinical visit, the Locator abutments were removed and four unmodified Universal Abutments were inserted using two light-cured resin orientation and seating jigs as sequenced according to the technician’s numerical markings on the master soft tissue model. Once the abutments were properly seated and the four milled retentive copings were passively fitted to the handcrafted polyceramic TRINIA® prosthesis, the copings were cemented with a resin cement into the bores of the TRINIA® framework, prior to delivering the new telescopic prosthesis to the patient.
