cults3d

Product Name: Individual TMJ Prosthesis (hereinafter referred to as Prosthesis). Scope of application: The prosthesis is designed for total replacement of the right TMJ. The prosthesis consists of the following components: * Prosthetic condylar process (Ti6Al4V, 96×29×18 mm, 23 grams); * Joint cavity prosthesis (surgical polyethylene, 30×15×26 mm, 2 grams). The design of the prosthesis takes into account the following features: * The condyle process will be removed before the Prosthesis is installed; * The articular cavity of the upper jaw is pre-treated before installing the prosthesis. Parameters of the fastenings of the prosthesis components * The prosthesis of the condylar process has 5 holes for 2.7 mm mounting screws; • After resection of the condyle process, the prosthesis rests on a branch of the lower jaw and chewing tuberosity; * The joint cavity prosthesis has 4 holes for 2 mm screws * Fastening of the joint cavity prosthesis occurs by fixing with screws. Screwing the screws must be carried out without much effort, in order to avoid a breakthrough of polyethylene by cooking the screw.
