example

[0051] Example: such as figure 1 Shown is a two-dimensional schematic diagram of the porous dental implant that can carry a drug sustained release system. The main body of the implant is a structure of revolution, with threads between the neck and the root, and the outer diameter of the threads is the same as the diameter of the implant neck. In the middle part of the implant, a porous structure is created at the thread intervals. The implant size is 3.75*10mm, the neck diameter is 3.75mm, and the length is 10mm. The cross-sectional area of ​​a single hole in the porous structure is rhombus, its diagonal length is 0.5 mm, and its depth is also 0.5 mm. The holes are uniformly distributed at equal intervals in the axial direction, and are helically distributed in the circumferential direction, and a hole is established every 60°.

Abstract

The invention provides a porous dental implant capable of carrying a drug sustained release system. The porous dental implant comprises an implant body. An external thread connected with alveolar bone is arranged on the outer surface of the implant body. Porous structures are formed among adjacent threads of the external thread. Pores used for storing sustained release drugs are formed in the porous structures. The invention provides a preparing method of the porous dental implant capable of carrying the drug sustained release system. According to the porous dental implant capable of carrying the drug sustained release system and the preparing method thereof, bonding strength is effectively improved, bonding speed is increased, and a porous structure can be achieved easily.

Description

technical field [0001] The invention relates to the field of porous dental implants, in particular to a porous dental implant and a manufacturing method thereof. Background technique [0002] In recent years, the application of dental implant technology has aroused people's high attention. The implanted teeth can not only solve the confusion of traditional denture restoration, but also get rid of the inconvenience caused by movable dentures. close to natural teeth. The success of implant surgery and the good function of restoration depend on many factors, and the combination effect of implant and alveolar bone is one of the key factors. 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 have shown that compared with smooth surfaces, rough surfaces can increase the osseointegration surface area and are beneficial to implants. Combination with alveolar bone. H...
