JPH1066701A - Titanium-coated dental correcting instrument - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent elution of metallic ions, such as Ni or Cr from a dental correcting instrument, that may cause an allergy to metals, so as to allow even a patient who is allergic to metals to have orthodontia with peace of mind by coating the device with titanium. SOLUTION: This instrument comprises a titanium-coated dental correcting strap, a keeping device (tube, etc.), a wire, a face bow, and a lingual retainer. After the dental correcting strap is joined to the keeping device by welding, it is coated with titanium. The wire, the face bow, and the lingual retainer are directly (or after treatments if they are heat treated) coated with titanium.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention is an orthodontic appliance provided with a titanium coating. By treating the device with titanium coating, elution of metal ions that cause metal allergy such as Ni and Cr from the device can be prevented, and orthodontic treatment can be performed with confidence for patients with metal allergy. Become.

[0002] In recent years, orthodontic materials such as various brackets have been developed as a countermeasure against metal allergy, which is a problem. Conventionally, brackets such as titanium brackets and 24K gold-coated brackets have mostly been used. However, for patients with metal allergies, it is impossible to provide total medical treatment only by using some correction devices such as brackets. Also, according to my own research, Ni has been reported to induce metal ions, especially metal allergies, when heat treatment is applied to metals.
It was confirmed that the amount of eluted increased. In the orthodontic band ring / maintenance device, it is considered that the metal elution amount is large in the part where the band ring and the tube are welded and the joint part of the convertible cap, that is, the part that has been subjected to heat treatment. . For the same reason, the facebow, which is indispensable in the edgewise method, is also brazed, and the amount of elution from the heat-treated portion cannot be ignored. From the viewpoint of total treatment, wires, lingual retainers, and the like are also indispensable constituent devices.

[0003] Claim 1 of the present invention is to apply a titanium coating after bonding a band and an attachment (tube, etc.) by a welding service currently performed by each manufacturer of orthodontic materials. Thereby, it becomes possible to apply a titanium coating also to a portion where the strap and the attachment are joined and a portion where the convertible cap of the tube is joined. Claims 2 and 3
This is also a titanium coating treatment for preventing elution of metal ions from the straightening device.

At present, a titanium coating, which is said to have the best affinity for the human body, is applied to prevent the elution of metal ions, such as Ni and Cr, which cause metal allergies from the orthodontic device, and to provide patients with metal allergies. It is possible to perform orthodontic treatment with confidence. Also,
Since there are many surgeons who use a wire for correction after heat treatment, it can be dealt with by applying a coating after the heat treatment.
