Problems solved by technology

[0007] 1) When the implant material is used, it may be in the middle of biological aging or in a state of completion, and there is a concern that it cannot be used in the best condition
[0008] 2) When installing the implant material, it is extremely difficult to know the date of manufacture of the implant material, so it is not clear to what extent the titanium surface has deteriorated
[0009] 3) Therefore, even if it is the same brand, there may be differences in the ability to bind to bone depending on the product
[0023] However, patent documents 9, 10, and 11 show an example of a device for producing ozone water by electrolysis, which can generate electrolytic ozone water suitable for the surface treatment of the implant material of the present invention, but whether it can be suitable for implantation The surface treatment of the material is completely undisclosed

Embodiment

[0115] Examples of the present invention are shown below.

[0116]

[0117] A cylindrical ion-exchange membrane (Nafion350, thickness 0.35 mm, diameter 3 mm) (Nafion is a registered trademark of DU PONT Co., Ltd.) is wound spirally on a niobium rod-shaped (diameter 2 mm) anode (formed with a conductive diamond catalyst ( The doping concentration of boron is 2500ppm)), and a platinum wire is wound on the separator to form an anode-membrane-cathode assembly. Pure water was flowed in at a rate of 40 mL per minute from the lower part of the electrolytic cell to which this membrane-electrode assembly was mounted. A current of 0.5A was passed, and as a result, due to the spiral diaphragm, oxygen, ozone, and hydrogen generated from the anode were mixed to generate electrolyzed water in which they were dissolved. The battery voltage at this time was 10V, and ozone water The concentration is 4ppm.

Embodiment 2

[0123] Put the niobium rod-shaped (diameter 2mm) anode (formed with a conductive diamond catalyst (boron doping concentration 2500ppm)) into a cylindrical ion-exchange membrane (Nafion350 manufactured by DU PONT Co., Ltd., thickness 0.35mm, diameter 3mm); As the cathode, a commercially available platinum wire (diameter: 0.4 mm) was spirally wound on the membrane to form an anode-membrane-cathode assembly. The spacing of the spirals is 4 mm. Tubes (diameter 4 mm) were bonded to the upper and lower sides of the junction, and the power supply lines of the electrodes were connected from a DC power supply to form an electrolytic cell, and pure water was flowed in at 40 mL per minute from the lower part of the anode chamber. A current of 1A was passed, and as a result, the battery voltage at this time was 19V, and the concentration of ozone water was 21ppm.

[0124] The same test as in Example 1 was carried out. As a result, carbon compounds on the titanium surface were reduced by ...

Abstract

A processing method for an implant material having excellent biocompatibility, in particular, a processing method and processing device for a dental implant material. A processing method and processing device for implant material having excellent biocompatibility, characterized in that an implant material composed of titanium or titanium alloy and having a roughened surface is immersed in electrolytic ozone water, the electrolytic ozone water is held at normal temperature, whereby pollution caused by adsorption of carbides onto the surface of the implant material is prevented, and hydrophilicity is imparted.

Description

technical field [0001] The present invention relates to a treatment method and a treatment device for an implant material excellent in biocompatibility, in particular, a dental implant material. Background technique [0002] In dental implant surgery, it is important that the implant is sufficiently integrated with the bone (osseointegration). As an implant material used for insertion into bone, titanium metal or a titanium-based alloy is used, which is characterized in that the material has excellent bioaffinity and can shorten the osseointegration time. However, since titanium implants with a smooth surface structure do not form sufficient integration in the bone, the surface must be roughened. Patent Documents 1 and 2 propose that in the initial process, a large rough surface is formed on the surface of an implant material composed of titanium or a titanium-based alloy by sandblasting, and then, the large rough surface is formed by treatment in an acid bath. The rough s...
