Problems solved by technology

The disadvantage of this kind of dental implant is that the abutment adopts solid materials, which cannot realize the liquid exchange between the implanted part of the dental implant and the exposed part, which is not conducive to the fusion of the dental implant and human tissue after implantation. At the same time, the artificial dental implant When in u

Embodiment 1

[0028] The artificial tooth implant in this embodiment is made of pure titanium. The porous material of the abutment has a pore diameter of 430nm-470nm and a porosity of 40%. The porous material of the neck has a pore diameter of 5µm-40µm and a porosity of 53%. The pore size of the porous material is 100µm-300µm, and the porosity is 58%. The pores of the three porous materials of the abutment, the neck and the body are interpenetrated respectively, and the pores of the porous material of the abutment and the porous material of the neck are interpenetrating. , the pores of the porous material of the neck and the porous material of the body are interconnected.

[0029] The preparation method of the artificial dental implant is as follows: uniformly mix pure titanium powder with a particle size of 90nm-160nm and ethyl cellulose with a particle size of 490nm-530nm according to the volume ratio of 3:2, and put them in according to the size of the abutment. In the mold prepared by s...

Embodiment 2

[0032] The artificial dental implant of this example is similar to Example 1, except that it is prepared with tricalcium phosphate, the pore diameter of the porous material of the abutment is 330nm-380 nm, the porosity is 70%, and the pore diameter of the porous material of the neck is 10µm -20µm, the pore size of the porous material in the body is 300µm-600µm.

Embodiment 3

[0034] The artificial tooth implant of this example is similar to Example 2, except that it is made of niobium, the pore diameter of the porous material of the abutment is 280nm-340nm, and the porosity is 65%.

Abstract

The invention provides an artificial tooth implant. The artificial tooth implant is composed of a body part, a neck part and an abutment, wherein the body part is a porous material; pores of the porous material are mutually communicated; the neck part and the abutment are porous materials; pores of the porous material of the abutment and pores of the porous material of the neck part are mutually communicated; pores of the porous material of the neck part and pores of the porous material of the body part are mutually communicated; the pore diameter of the porous material of the abutment is 500nm or below. By adopting the artificial tooth implant provided by the invention, a part, which is implanted into a human tissue, of the tooth implant and an exposed part can be subjected to liquid exchange, so that bacteria are prevented from entering and infection is prevented; impact on a gum, caused by a chewing force of teeth, can be effectively buffered and the fusion time between the implanted tooth implant and a human bone tissue is shortened.

Description

technical field [0001] The invention relates to the field of dental implants, in particular to an artificial dental implant. Background technique [0002] In recent years, with the development of dental implant technology, dental implants have become one of the main restoration methods for missing and defective dentition. Compared with other traditional restoration methods such as complete dentures, partial removable dentures, and fixed dentures, dental implants have obvious advantages: first, they have strong functions and can restore tooth functions well, and their chewing function is much better than other traditional dentures; If you don’t grind your teeth, you can rely on your own artificial tooth root for repair. You don’t need to grind the healthy teeth next to it, and there is no harm to the teeth; moreover, the retention is good, and you don’t use traditional clasps or braces, and the artificial tooth root alveolar bone is tightly integrated. , rooted in the oral c...
