Titanium-based three-dimensional network structure artificial bone implant

Abstract

The invention discloses a titanium-based three-dimensional network structure artificial bone implant. The artificial bone implant comprises several three-dimensional members. Each one of the three-dimensional members comprises four columns. The four columns have the same length and are connected at a point. Included angles of the connected columns are the same. The three-dimensional members are linearly arranged along a transverse direction, are staggeredly arranged along a longitudinal direction and are connected with each other. Included angles of the columns of the connected three-dimensional members are the same, the three-dimensional members form member bodies, the member body layers are overlaid layer by layer, and included angles of the columns of upper and lower layers of the overlaid three-dimensional members are the same, and the artificial bone implant with a three-dimensional network structure with same column included angles is formed. The artificial bone implant has a three-dimensional network structure and is conducive to growth of bone into the three-dimensional network structure gap. Large spaces around the columns are formed and are communicated so that blood supply conditions for growth of bone into the three-dimensional network structure gap are completely satisfied. Therefore, the bone can completely grow into the implant so that strength and a retention force similar to those of a natural tooth root are obtained.

Description

technical field [0001] The invention belongs to a biologically adaptable single-material dental implant, in particular to a titanium-based three-dimensional mesh frame artificial bone implant. Background technique [0002] In recent years, dental implant technology has been widely used clinically, and very satisfactory results have been obtained. Dental implants are implants that are artificial tooth roots implanted into the alveolar bone, and then the teeth are fixed on the implants to repair missing teeth. Dental implants not only solve the inconveniences that traditional dentures bring to people, but also are very beautiful, natural in effect, comfortable in feel, and their occlusal force is close to that of natural teeth. The success of dental implants depends on many factors, and the combination effect of implants and alveolar bone is one of the most important factors. Existing implants are titanium or titanium alloy solid cylinders with threads, and the surface is sa...

AI Technical Summary

Problems solved by technology

Although the pores of this kind of dental implant are connected, they are not transparent. The pores are curved and tortuous, and are blocked by layers. The pores are still narrow relative to their diameter, which cannot meet the blood supply conditions for the bone to grow into completely. After the superficial long bone, this kind of porous structure will prevent the bone from continuing to grow inward. Therefore, the bone cannot grow into it completely, and satisfactory clinical results cannot be achieved.
