Clamp for local protection in chemical surface treatment of dental implant

Abstract

The invention discloses a clamp for local protection in the chemical surface treatment of a dental implant. The clamp comprises a main body sealing seat, sealing covers and a fastening screw rod, wherein the upper end surface of the main body sealing seat is provided with first grooves; after the sealing covers are fixed on the main body sealing seat by virtue of the fastening screw rod, the lower end surface of each sealing cover and each first groove form a clamping cavity with an opening end; the sealing end of each clamping cavity is respectively provided with a conductive device which can be connected with a power supply; the inner side wall of each clamping cavity is provided with a sealing groove; and each sealing groove is respectively provided with an annular sealing ring which can clamp the dental implant. Because the clamping cavities are internally provided with the sealing rings and the dental implant is clamped and sealed by the sealing rings, the sealing rings partition the dental implant into a part to be treated, which is exposed in a chemical treating solution, and a protection part sealed in the clamping cavities, and therefore the part to be treated on the dental implant can be subjected to chemical surface treatment after the dental implant is put in the chemical treating solution. The clamp disclosed by the invention is suitable for chemical surface treatment of the dental plants.

Description

technical field [0001] The invention relates to a fixture for local protection in the chemical treatment of the surface of the dental implant, which is suitable for the local chemical corrosion or electrochemical oxidation process in the surface treatment of the dental implant. Background technique [0002] Dental implants are widely used in missing or defective dentition surgery. The surface treatment of titanium metal dental implants is an essential processing technology in the processing technology of dental implants. During the chemical treatment of the surface of dental implants, chemical corrosion and electrochemical oxidation processes are essential treatment processes. In practice, only part of the surface of the dental implant requires chemical treatment, and the part that does not need to be treated must be protected during the treatment process. [0003] At present, for partial protection in chemical corrosion and electrochemical oxidation processes, coating met...

AI Technical Summary

Problems solved by technology

[0003] At present, for partial protection in chemical corrosion and electrochemical oxidation processes, coating methods such as styrene-acrylic butylene and wax are generally used, which have the following disadvantages and deficiencies: After chemical corrosion or electrochemical oxidation process, it is difficult to remove Coating layer; the coating layer is easy to peel off or break down in the process of hot strong acid, alkaline corrosion solution or electrochemical oxidation; when cleaning the coating, it may pollute or damage the treated surface

In addition, the use of these materials increases the process links, such as coating, curing, cleaning, etc., and the entire process is cumbersome and time-consuming

On the other hand, for electrochemical fixtures, the metal fixtures of the same material are severely corroded during the surface treatment process of strong acid and strong alkali, which will greatly shorten the service life of the metal fixtures

The fixture not only consumes the active ingredients in the treatment solution but also consumes additional power
