| titleOfInvention | Bone scaffold-tooth root integrated restoration and preparation method thereof |
| abstract | The invention provides a bone scaffold-tooth root integrated restoration and a preparation method thereof. The bone scaffold-tooth root integrated restoration is composed of a mesh bone scaffold for repairing jaw defects and at least one tooth root with a dense structure in the bone scaffold. The bone scaffold and the tooth root are formed into an integrated structure by 3D printing with PAx/mHA printing paste. The preparation method of the above-mentioned integrated restoration includes the following steps: (1) preparing a precursor solution; (2) preparing hydroxyapatite mHA nanoparticles co-doped with antibacterial ions and rare earth ions; (3) dissolving polyamide PAx into a mixed solution A polyamide PAx solution is formed in a solvent, and the mixed solvent is composed of formic acid and dichloromethane. The mHA nanoparticles are added to the polyamide PAx solution and stirred evenly to obtain a PAx/mHA printing paste. The PAx/mHA printing paste is By 3D printer printing, the bone scaffold-tooth root integrated restoration is obtained. The use of the integrated prosthesis of the present invention can effectively solve the problem of repairing the defect of the jaw and reconstructing the teeth on it. |
