NEW! Replacement of an O-ring Mandibular Overdenture with a Telescopic TRINIA®-HC Prosthesis Utilizing Gothic Arch Occlusal Registration Tracing

Posted on in Overdentures

This case demonstrates the clinical and laboratory procedures and techniques to replace a 10-year-old o-ring mandibular overdenture on three O-Ring Abutments with a telescopic prosthesis of TRINIA® and Shofu disc HC, CAD/CAM material, with three milled retentive copings on Universal Abutments in two clinical visits for a 75-year-old woman.

During the first clinical visit, the three O-Ring Abutments were removed from their implants, and three 2.0mm impression posts and corresponding acrylic sleeves were inserted for the making of a full arch implant-level transfer impression. An initial centric occlusal registration was recorded using modified acrylic impression sleeves at the patient’s existing vertical dimension of occlusion with the bite registration material, Capture. While the patient waited, the impressions were poured and the stone models articulated for the fabrication of a maxillary stylus and mandibular tracing plate to facilitate the registration of the patient’s centric relation utilizing the Gothic arch occlusal registration tracing. After recording the patient’s centric relation, the O-Ring Abutments were re-inserted, and the occlusal registration was sent to the dental technician for the fabrication of a telescopic TRINIA® substructure to which three separately milled teeth arrangements of Shofu disc HC material were bonded.

During the second clinical visit, the O-Ring Abutments were removed, and three Universal Abutments were inserted into the implants utilizing a light-cured resin orientation/seating jig, prior to the cementation of three milled retentive copings into the bores of the TRINIA®-HC prosthesis.

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 in Overdentures, Porcelain Fused to Metal

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.

Bar with Screw Retention

Posted on in Overdentures, Restorative

Bicon’s abutments for screw-retained restorations are designed with a 20 degree taper of the coronal portion, so elongation or breakage of retention screws is not a problem. Flexibility is provided with two abutments with gingival cuff lengths of 3.0mm and 5.0mm and with post angles of 0 and 15 degrees.
