Medical enhanced biodegradable GTR/GBR integrated film and preparation method thereof

Abstract

The invention discloses a medical enhanced biodegradable GTR / GBR integrated film and a preparation method thereof. The integrated film contains polylactic acid and a magnesium alloy hole plate packedin the polylactic acid, which are integrally shaped. In accordance with the situation that at current market, a biodegradable film is low in intensity and cannot maintain integrity for a long time, anon-biodegradable film needs to be operated for the second time, infection is easy to cause, and the pain of patients can be increased, the invention researches and develops the GTR / GBR integrated film having high intensity and biodegradable properties. The integrated film combines the advantages of the relevant biodegradable film and the non-biodegradable film materials as far as possible, so that the medical enhanced biodegradable GTR / GBR integrated film is high in intensity and appropriate in price.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a medical enhanced degradable GTR / GBR integrated film and a preparation method thereof. Background technique [0002] Currently, existing technologies in the industry: [0003] GTR / GBR membranes are mainly used in the surgical treatment of periodontal tissue regeneration. In periodontal surgery, the membrane material is used as a barrier to block the contact between the gingival connective tissue and the root surface, and provide a certain space to guide the periodontal ligament cells with the ability to form new attachments to preferentially occupy the root surface, so that the periodontal ligament cells that have been exposed to the periodontal New cementum is formed on the root surface in the pocket, and periodontal ligament fibers are embedded to form the regeneration of periodontal tissue, that is, the formation of new adhesive healing. [0004] The GTR / GBR membr...

Problems solved by technology

[0014] The present invention aims at the above deficiencies, and aims at the low strength of degradable membranes on the market, which cannot maintain the integrity of membranes for a long time; the non-degradable membranes require secondary operations, which are easy to cause infection and increase the pain of patients. A GTR / GBR integrated membrane with high strength and degradability has been developed. This integrated membrane combines the advantages of degradable membranes and non-degradable membrane materials as much as possible, with high strength and reasonable price.
