Embodiment 1

[0036] a. Use sandblasting medium at a pressure of 0.5Mpa to spray the part of the surface of the implant (that is, the jacket 12, the same below) that needs to be implanted into the alveolar bone. The spraying distance is 40mm, and the angle between the spraying direction and the axial direction of the implant is 30° and 150° alternately, but the last sandblasting is sprayed from the crown towards the root; until the surface of the implant loses its metallic luster and turns gray; in this way, uniform micropores or small concave holes with a certain size are formed on the pure titanium surface. Pit, micropore diameter 50 ~ 150μm.

[0037] In sandblasting, the particle size of the sandblasting medium is 0.1-0.3mm, and the weight composition is 80% of white corundum, 6% of titanium phosphate, and 14% of corundum.

[0038] b. Rinse the surface of the implant with anhydrous purified water 4 times, each time for 2 minutes, to remove the sandblasting medium remaining on the surface...

Embodiment 2

[0042] a. Use sandblasting medium at a pressure of 0.6Mpa to spray the part of the implant surface that needs to be implanted into the alveolar bone. The spraying distance is 80mm, and the angle between the spraying direction and the axial direction of the implant is 45° and 135° alternately, but the last pass Sandblasting is sprayed from the crown towards the root until the surface of the implant loses its metallic luster and turns gray; in this way, uniform micropores or small pits with a certain size are formed on the pure titanium surface, with a micropore diameter of 50-150 μm.

[0043] In sandblasting, the particle size of the sandblasting medium is 0.1-0.3mm, and the weight composition is 90% of white corundum, 2% of titanium phosphate, and 8% of corundum.

[0044] b. Rinse the surface of the implant with absolute ethanol for 5 times, each time for 2 minutes, to remove the sandblasting medium remaining on the surface;

[0045] c. Put it into the mixed acid solution, and...

Embodiment 3

[0048] a. Use sandblasting medium at a pressure of 0.55Mpa to spray the part of the implant surface that needs to be implanted into the alveolar bone. The spraying distance is 60mm. The angle between the spraying direction and the axial direction of the implant is 60° and 120° alternately, but the last pass Sandblasting is sprayed from the crown towards the root until the surface of the implant loses its metallic luster and turns gray; in this way, uniform micropores or small pits with a certain size are formed on the pure titanium surface, with a micropore diameter of 50-150 μm.

[0049] In sandblasting, the particle size of the sandblasting medium is 0.1-0.3mm, and the weight composition is 85% of white corundum, 3% of titanium phosphate, and 12% of corundum.

[0050] b. Rinse the surface of the implant with purified water for 5 times, 2 minutes each time, to remove the sandblasting medium remaining on the surface;

Abstract

The invention relates to a dental implant, and aims at providing a stable and lasting dental implant structure. The dental implant structure comprises an implant, a base station and a central bolt; the upper portion of the implant is located in the gingival, the lower portion of the implant is implanted into the alveolar bone, the lower end of the base station is inserted into an installing hole formed in the upper portion of the implant, the base station is provided with a communicated stepped inner hole, the central bolt fixes the base station into the installing hole through the stepped inner hole formed in the base station, and the base station is used for installing a dental crown; the implant comprises an inner sleeve and an outer sleeve which are coaxially arranged; the installing hole is located at the upper end of the inner sleeve, the outer wall of the inner sleeve is provided with an outer thread, the inner wall of the outer sleeve is provided with a matched inner thread, and the inner sleeve is in threaded connection with the outer sleeve; the outer sleeve is made of pure titanium, the outer surface of the outer sleeve is provided with an outer thread, the outer sleeve is subjected to surface treatment to be in anchor combination with the alveolar bone, and the inner sleeve is made of titanium alloy. The dental implant is good in durability and stable and reliable in performance.

Description

technical field [0001] The invention relates to the field of oral medicine, in particular to a dental implant structure and a corresponding processing method. Background technique [0002] Oral health problems have always been an important issue in the medical field, and tooth loss is the main cause of oral diseases. For tooth defects, it is generally possible to make up if it can be repaired; if it cannot be repaired, it is necessary to extract and make a denture. Dental implants are a typical form of dentures. Compared with traditional denture restorations, dental implants are to implant the implant (that is, the artificial tooth root) into the alveolar bone, then install the abutment on the implant, and finally install the abutment on the abutment. Restoring the form and function of the tooth by installing the crown portion on the bench. Dental implants have strong retention and stability, and can be rooted in the patient's mouth like real teeth; there is no dull taste ...
