Description

Metal oral cavity diaphragm and preparation device thereof Technical Field The application relates to the technical field of oral implants, in particular to a metal oral membrane and a preparation device thereof. Background The dental implantation technology becomes a conventional repair treatment means for the tooth deficiency, and the absorption change of alveolar bone is inevitably caused clinically due to periodontitis, tooth shedding, trauma and other reasons, such as the bone defect problems of too low, too narrow and partial dents of the alveolar ridge, and the bone defect problems are easy to cause implantation failure or poor effect. Melcher found and proposed a treatment method for guiding tissue regeneration for the first time in 1976 in the treatment of periodontal diseases, and applied to clinic, the method was found to be capable of effectively promoting alveolar bone mass and promoting periodontal attachment regeneration. Subsequently, more and more studies have shown that the introduction of biological barrier membrane materials in periodontal disease guided tissue regeneration treatment can effectively act to prevent fibroblasts from surrounding soft tissue, allowing sufficient time for osteoblasts at the bone surface to proliferate and thereby regenerate bone tissue. Currently, common biological barrier membrane materials include synthetic polymers, natural polymers, metals, and inorganic compounds. The magnesium and the alloy thereof are used as light and high-biocompatibility metal materials, and have the following properties of (1) good biocompatibility, (2) complete degradation, (3) proper mechanical property, the density of the magnesium alloy is matched with that of human bones, the elastic modulus is closest to that of natural bones, the specific strength of the magnesium alloy is higher than that of titanium, and (4) the magnesium alloy has good formability.
