Abstract

The invention discloses a 3D printing-based bionic artificial tooth and a manufacturing method thereof. The 3D printing-based bionic artificial tooth comprises a bionic dentin main body, a bionic enamel layer coating the upper end surface of the bionic dentin main body and a bionic cementum layer coating the bionic dentin main body, the bionic enamel layer is connected to the bionic cementum layer through a transition region, the outer surface of the bionic cementum layer is covered with a microstructure layer, and the microstructure layer comprises porous structures and barb structures staggered or irregularly distributed on the bionic cementum layer. According to bionic characteristics, solids with different gradient strength are molded in different implantation material areas so that stress interference between an implantation material and an alveolar bone is reduced. Through combination with a high freedom degree molding capability of the 3D printing technology, a completely personalized bionic dental implant is directly molded so that wearing comfort is improved. The barb structures and the porous structures are conducive to cell adhesion, growth and fixation, improve a bonding capacity of an implant and an alveolar bone and reduce adverse effects such as a dental implant falling risk after an operation.

Description

technical field

[0001] The invention relates to dentures with 3D printing technology, in particular to a bionic denture based on 3D printing and a manufacturing method thereof. Background technique

[0002] Artificial tooth implant is a common treatment for tooth loss at present. It mainly implants a biocompatible metal artificial tooth root into the alveolar bone at the tooth loss, and through the close integration of artificial tooth root and alveolar bone, The artificial tooth root is used as the base to install the dental mold. Since the adjacent teeth are not ground away like fixed dentures, there is no damage to adjacent teeth, and there is no factor for secondary tooth decay, so it is a more stable method than fixed dentures. When people use removable dentures due to missing multiple teeth, they will exert force on the periodontal tissue (gum), so the gums will feel uncomfortable, and the foreign body sensation in the oral cavity is serious, and because implants and ...
