Problems solved by technology

It’s all because the melting point of titanium is above 1550°, and high temperature is required in order to stick firmly. High temperature causes chemical reaction, denaturation of hydroxyl group, reduction of crystallinity, or increase of material brittleness, cracking of substrate, which affects the practical effect and cannot be clinically confirmed.

Embodiment 1

[0013] Mix 30μm-40μm titanium powder and dextrin (1:1 ratio of titanium powder and dextrin), spray evenly on the titanium helical implant, control the thickness between 0.02-0.05mm, and move it to the dentist after drying In the commonly used zirconia sintering furnace, negative 2 atmospheres, vacuum sintering, the temperature is controlled between 1000-1200 °C, and then annealed to restore the original toughness of the sintered hardened and brittle titanium ash, and check whether it is bonded Firm, whether the pores meet the requirements (pores 2-15μm, 1-3 layers of pores connected to each other), otherwise, recoat and burn again according to the above method.

[0014] Artificial bone is a trade name, of which hydroxyapatite is the most commonly used. Just buy nano-scale hydroxyapatite powder, add 20% water to make a slurry; self-grinding requires a particle size of 1-3 μm, and vacuum pour it into the pores of the firmly bonded layers of titanium sand. The artificial bone ma...

Embodiment 2

[0018] Mix 30μm-40μm titanium powder and dextrin (1:1 ratio of titanium powder and dextrin), spray evenly on the titanium helical implant, control the thickness between 0.05-0.08mm, and move it to the dentist after drying In the commonly used zirconia sintering furnace, negative 2 atmospheres, vacuum sintering, the temperature is controlled between 1400-1500 ° C, and then annealed to restore the original toughness of the sintered hardened and brittle titanium ash, and check whether it is bonded Firm, whether the pores meet the requirements (pores 2-15μm, 1-3 layers of pores connected to each other), otherwise, recoat and burn again according to the above method.

[0019] The artificial bone material is selected from bio-glass ceramics (BGC), which is available in the market, and 30% of water is added to make a slurry. After the titanium powder is sintered on the surface of the implant, put it into the mortar. There is air in the pores between the titanium powder, forming air b...

[0022] Mix 30μm-40μm titanium powder and dextrin (1:1 ratio of titanium powder and dextrin), spray evenly on the titanium helical implant, control the thickness between 0.02-0.08mm, and move it to the dentist after drying In the commonly used zirconia sintering furnace, negative 2 atmospheres, vacuum sintering, the temperature is controlled between 1200-1300 ° C, and then annealed to restore the original toughness of the sintered hardened and brittle titanium ash, and check whether it is bonded Firm, whether the pores meet the requirements (pores 2-15μm, 1-3 layers of pores connected to each other), otherwise, recoat and burn again according to the above method.

[0023] The artificial bone material is commercially available in calcium triphosphate (TCP), and 25% water is added to make a slurry. After the titanium powder is sintered on the surface of the implant, put it into the mortar. There is air in the pores between the titanium powder, forming air bubbles. The artificial ...

Abstract

The invention discloses a method for fusing a bioactive material on the surface of an artificial tooth pure titanium spiral-shafted implant. The method comprises the following steps of: coating a layer of titanium slurry of 0.02-0.08 millimeter on the surface of the artificial tooth pure titanium spiral-shafted implant, sintering in vacuum after the titanium slurry becomes dry, and controlling the temperature at 1,000-1,500 DEG C; adding 20-30 percent of water into nano-scale artificial bone meal for bending into paste, filling titanium holes with a vacuum grouting method, and sintering at a low temperature; coating a layer of bone to form proteins, and performing freeze drying and refrigeration for later use; or before clinical use, wrapping with blood platelet-rich blood plasma. The method has the advantages of easiness, convenience, avoidance of the influence of high temperature on a material, reduction in hydroxyl denaturation and crystallinity degree, material crispness, cracking and stripping of a substrate, no need of special equipment, low cost, easiness for batch production, and the like.

Description

technical field [0001] The invention relates to a method for preparing a metal titanium artificial tooth implant, in particular to a method for fusing and attaching bioactive materials to the surface of an artificial tooth pure titanium spiral implant. Background technique [0002] Dental implant technology has been researched and used in my country for more than 20 years. Domestic implants are still bare titanium plus sandblasting. Our country was funded by the Natural Science Foundation of my country 24 years ago. The former Sichuan University, the former West China Medical College and the Institute of Optoelectronics have research activities Artificial bone hydroxyapatite (HA) and bioglass-ceramic (BGC) were successful. It passed the appraisal in September 1986 and reached the international advanced level. It won the first prize of the Chinese Academy of Sciences. Finally, it was rejected by the West China Medical College due to the poor bonding of the base. Up to now, no...
