Embodiment 1

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

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

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

[0039] c. Put it in the mixed acid solution, and perform aci...

Embodiment 2

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

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

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

[0045] c. Put it in the mixed acid solution, and perform acid etching treatment at 105°C and 90% relative humidit...

Embodiment 3

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

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

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

[0051] c. Put it in a mixed acid solution, and perform acid etching treatment at 105°C and a relative humidit...

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 dental defects are the main cause of oral diseases. For tooth defects, it is generally possible to make up or make up; 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 consist of first implanting an implant (that is, an artificial root) into the alveolar bone, then installing an abutment on the implant, and finally The crown part is installed on the table to reshape the shape and function of the tooth. Dental implants have strong retention and stability, and can be rooted in the patient's mouth like real teeth; there is no dull taste and uncomfortable taste caused by traditiona...
