3-D Printed Bite Registration Jigs for Distal Free End Implant Restorations

Objective: To demonstrate a technique to minimize the cost and the time by recording the bite at the time of impression taking procedure. Materials and methods: During the impression procedure, bite registration was obtained, by engaging one Bite Registration Jig (BRJ) on the distal implant. Vertical height was adjusted instantly, using a round-end taper acrylic bur. Retention grooves were pre-designed and fabricated by the printer. Blu-Mousse material was injected around the fabricated jig and patient occluded in a centric relation position. Subsequently, the BRJ, embedded in Blu-Mousse material, was used extraorally to mount the fixture level cast with the opposing cast. Results: All implant restorations had stable interocclusal contacts with no eccentric contacts, hence all accepted. All the four Fixed Dental Prostheses were delivered at the try in procedure, with minimal chair side adjustments using the porcelain polishing burs. Conclusion: Bite registration with BRJ is an accurate and effective technique, which can be used for the distal extension implant cases. In addition, unlimited BRJ's can be produced by the 3D printing in a short amount of time and inexpensively.
