Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] refer to Figure 1 to Figure 5 , a multi-segment through-hole porous dental implant, comprising a gingival section and a threaded section, the gingival section is a smooth solid structure, the gingival section is located on the upper part of the threaded section, and the dental implant also includes a porous structure section, the porous structure section is located at the bottom of the threaded section, and in the porous structure section, a porous structure with increasing pore diameter is adopted sequentially from bottom to top; The through holes are radial, and the transverse through holes are distributed along the circumference.

[0033] Further, the transverse through-holes of one type of aperture are misaligned with the transverse through-holes of adjacent upper and lower apertures.

[0034] Or: the transverse through holes of one aperture and the trans...

Abstract

The invention discloses a multistage through-hole porous tooth implantation body. The multistage through-hole porous tooth implantation body comprises a gingiva passing through segment and a screw thread segment; the gingiva passing through segment is of a smooth solid structure, and is arranged on the upper part of the screw thread segment; the multistage through-hole porous tooth implantation body also comprises a porous structure segment; the porous structure segment is arranged on the lower part of the screw thread segment; the hole diameter of transverse through holes on the porous structure segment from the lower part to the upper part is increased successively; the transverse through holes with the same hole diameter are arranged in a radiation manner along the periphery of the porous structure segment. The multistage through-hole porous tooth implantation body is capable of increasing combination strength, increasing combination speed, and is provided with the porous structure conveniently.

Description

technical field [0001] The invention relates to the technical field of dental implant restoration, in particular to a multi-segment through-hole porous dental implant. Background technique [0002] Tooth loss will bring inconvenience to people's life, and the restoration of dentures can no longer meet people's needs. In recent years, the development of dental implant technology has successfully solved this problem for us. Dental implants are bionic teeth made from natural teeth. It is mainly divided into two parts: the crown that bears the chewing force and the implant that is screwed into the mandible. The success of dental implants is largely determined by the implant. A successful dental implant should allow the implant to form complete osseointegration with the mandible and have good biocompatibility. In order to promote the integration of implants and alveolar bone, dental implants with rough surfaces have been widely used. Animal experiments and clinical practice h...
