The XL Dental Implant System is intended for implantation in the maxillary or mandibular molar region where bone exists and the surgeon has determined that the placement of a narrower diameter implant would increase the probability of failure due to poor primary stability, or increased surgical procedures leading to complications. This XL implant system provides support for fixed or removable dental prostheses in a single tooth, partially edentulous prostheses or full arch prostheses. It further adds the option for immediate loading on single and splinted multiple unit restorations when good primary stability is achieved and with appropriate occlusal loading, to restore chewing function.

This submission includes threaded root-form dental implants with large diameter for use in the molar region. The implants are provided in diameters of 7, 8 and 9mm and lengths of 7, 9 and 11mm. This submission also includes mating components: Cover screws; Healing Abutments in varying diameters and cuff heights; Titanium Cylinder abutments for temporary restorations; Titanium Abutments in varying diameters and cuff heights for permanent restorations; and the abutment screw. The XL implants are manufactured from titanium alloy conforming to ASTM F136. The implants have a is grit blasted, acid etched (SLA) surface. The Cover Screw, Abutments and Abutment Screw are manufactured from titanium alloy conforming to ASTM F136.
