The invention provides a porous tantalum dental implant manufacturing method based on AI and 3D printing, and relates to the technical field of stomatology and 3D printing, and the porous tantalum dental implant manufacturing method comprises the following steps: S1, establishing a historical CBCT data set; using the historical CBCT data set to train and construct an oral cavity reconstruction model in an AI modeling platform based on a deep learning algorithm; s2, generating a corresponding oral cavity reconstruction model according to the CBCT of the oral cavity of the patient; the implant three-dimensional model comprises a dental crown, a dental base and an implant matrix; the planting matrix is of a gradient porous structure and is divided into a surface layer area, a transition area and a core area from top to bottom, and the porosity and the aperture of the surface layer area are gradually reduced. S3, adjusting the shape and size of the implant three-dimensional model, and optimizing the implant three-dimensional model; s4, performing 3D printing to obtain an implant; and S5, preparing hydroxyapatite coatings on the outer surface of the planting matrix and the inner wall surfaces of the internal pores. The problems that in the prior art, the elastic modulus of an implant is not matched, the osseointegration efficiency is low, and the adaptability of a restoration is poor are solved.

The application belongs to the technical field of biological medicine, and particularly relates to a preparation method of a collagen dental base paste raw material for oral cavity and application thereof. The steps are as follows: firstly, dissolving recombinant collagen in water for injection to form a collagen solution; then adding hydroxyapatite and an aqueous solvent into an oil phase solvent, stirring uniformly to obtain a hydroxyapatite suspension; then preparing an EDC solution and an NHS solution, mixing the two, and adding the mixture into the collagen solution to obtain a collagen mixture; then adding the hydroxyapatite suspension, and after ultrasonic treatment, centrifugation and natural air drying, the collagen dental base paste raw material for oral cavity is obtained. The application uses the combination of the aqueous solvent and the oil phase solvent, so that the Hap and the collagen can better form a polymer; the use of the collagen, the NHS and the EDC can improve the antibacterial performance; and the final product is in the form of powder (nanoscale), has delicate texture, can strengthen the effects of hydroxyapatite remineralization and desensitization, and realizes the combination of gum protection, caries prevention and anti-inflammatory function.
