Embodiment 1

[0029] 1) Use pure magnesium and AZ31 magnesium alloy to make a 0.1mm thick film;

[0030] 2) Step 1) After the surface polishing of the three membrane materials, they were ultrasonically cleaned with acetone, absolute ethanol and deionized water for 30 minutes in sequence, and dried;

[0031] 3) Preparation of micro-arc oxidation electrolyte: deionized water is used as solvent, prepared as 0.8g / L NaOH, 3.5g / L (NaPO 3 ) 6 and 8g / L KF mixture;

[0032] 4) Preparation of micro-nano porous coating by micro-arc oxidation method: AZ31 magnesium alloy film is used as the anode, stainless steel is used as the cathode, a composite pulsed micro-arc oxidation bipolar power supply with a power of 2kW is selected, the set voltage is 360V, the working frequency is 1000Hz, the intensity 40%, the processing time is 5 minutes;

[0033] 5) After the preparation is completed, ultrasonically clean with acetone, absolute ethanol and deionized water for 30 minutes in sequence, and dry;

Abstract

The invention relates to an application of magnesium material as oral cavity GTR or GBR membrane material. The magnesium material can adopt magnesium base alloy; no matter from the price of the raw material, or from the preparation of the later-stage material, the cost of magnesium is far lower than that of the existing GTR / GBR membrane available in clinic, so that the production cost and the final treatment expense can be reduced; the density and the elasticity modulus of the magnesium base alloy are far higher than those of the existing absorbable GTR or GBR membrane, therefore, the magnesium base alloy is obviously superior to the traditional GTR / GBR membrane in the aspect of physical barrier, and the loss of the effect of the screening space due to the collapse of the GTR / GBR membrane in the defect area is avoided; and meanwhile, the magnesium base alloy material also has the advantages of low immunogenicity and good antibacterial property.

Description

technical field [0001] The invention relates to oral cavity GTR or GBR membrane material, in particular to the application of magnesium material as oral cavity GTR or GBR membrane material. Background technique [0002] Periodontitis is one of the most prevalent and destructive diseases of the human oral cavity. It destroys the integrity of the periodontal tissue system, leading to the inflammatory loss of the periodontal tissue, and then affects the chewing function of the teeth or whether the teeth can Retention; the leading cause of tooth loss in adults. The National Institutes of Health NIDCR (National Institutes of Health, United States) statistics, nearly 90% of people over the age of 70 suffer from periodontal disease above the moderate level, and the data shown in the third national oral health survey report in my country in 2005 is even more Severe, manifested as the age of the affected patients is younger, the number of people is larger, and the number of lost teet...
