Abstract

The invention relates to a dental implant and belongs to the field of medicine. The personalized dental implant is characterized by comprising a tooth root and an abutment. The shape and size of the tooth root are matched with alveolar bone, and the porosity in the axial and circumferential directions of the tooth root changes in a gradient way, so that the elastic modulus of the tooth root is matched with the elastic modulus of the alveolar bone to eliminate a stress shielding effect, and the force transfer effect between the dental implant and the alveolar bone is relatively good; the surface of the tooth root is mineralized to promote the integration of the dental implant and bone; the abutment and a tooth root connection section are inwardly sunken to form a gingival recess filled with an adhesive to improve the stability of the dental implant. The invention also relates to a method for manufacturing the dental implant. The method is characterized in that the alveolar bone space configuration and the bone elastic modulus are obtained by a medical imaging technique; and then the three-dimensional shape and elastic modulus of the matched dental implant are derived reversely; after 3D printing integral molding, the dental implant of which the shape, size and elastic modulus are matched with those of the alveolar bone is prepared.

Description

technical field

[0001] The invention relates to a dental implant, in particular to a personalized dental implant and a manufacturing method thereof. Background technique

[0002] As the average human age increases, the restoration of teeth is becoming increasingly important in the medical field. Dental implant is the key technology in the field of dental restoration. As a dental implant implanted externally in the oral cavity, its connection strength with the alveolar bone, its own mechanical properties and biocompatibility are the main factors affecting the effect of the dental implant.

[0003] In some existing technologies, CT imaging technology is used to obtain the shape of the alveolar bone, and then a dental implant matching the shape of the alveolar bone is prepared. The elastic modulus (110GPa) of this densely structured titanium implant is much greater than that of bone Due to the mismatch of the elastic modulus, stress concentration and stress shielding effects ...
