本発明は、Ｇａ系液体金属と金属粉末とを混合練和して
用いる歯科用金属線成充填材に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a dental metal wire filling material that is used by mixing and kneading a Ga-based liquid metal and a metal powder.
歯科用金属線成充填材としては永年にわたって水銀に銀

準備や取扱の点で作業性に優れるために現在まで使用さ
れてきた。Amalgam, which is a mixture of mercury and silver alloy powder, has been used as a dental metal wire filling material for many years. In other words, the amalgam obtained by mixing and kneading a predetermined amount of liquid metal mercury and silver-based alloy powder with a predetermined composition is filled into the cavity of a patient's tooth, and the alloying reaction progresses after filling. It hardens to withstand occlusion, and has been used until now because it is easier to prepare and handle than other dental alloys for casting.
しかし、上記の従来技術は水銀を用いているために、そ
の有害性から患者や取扱者に対する毒性および環境汚染
の問題が社会的に高まってきた。However, since the above-mentioned conventional technology uses mercury, problems of toxicity to patients and handlers and environmental pollution have increased socially due to its toxicity.

には到っていない。Therefore, as a metal wrought filling material for dental restorations that does not use mercury-based amalgam, Ga is used as a liquid metal to replace mercury.
Single substance or Ga-3n alloy mainly composed of Ga, Ga
A binary alloy of -Inn conjugate alloy Ga -Znn conjugate alloy or a combination thereof is used, and the metal powder is a single metal powder such as Au, Ag, Cu, Sn and Zn or Au Fundamental research has been conducted using powders of alloys such as alloys and Ag alloys, targeting mixed kneaded products made from combinations of these liquid metals and metal powders. However, compared to mercury-based amalgam, it still has insufficient handling and various properties as a dental restorative material, and has not been put into practical use.
