Embodiment Construction

[0021] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] Such as figure 1 and figure 2 As shown, the pure titanium movable denture bracket provided by the present invention with a vitaline clasp includes a bracket body 1 , a connecting portion 3 and a clasp 2 .

[0023] The bracket body 1 is made of medical pure titanium metal. The bracket body 1 has a grid structure. The bracket body 1 is curved, and the degree of curvature conforms to the shape of the oral cavity and gums.

[0024] The snap ring 2 is made of Vitalink, which is a cobalt-chromium-molybdenum alloy containing 63.4% cobalt, 29% chromium and 5.2% molybdenum; The specific physical properties are: yield strength 648mpa, tensile strength 934mpa, elongation coefficient 11.6%, Vickers hardness: 373. It has the advantages of good bending controllability, strong deformation resilience, strong fracture resistance, beautiful appea...

Abstract

The invention discloses a pure titanium removable denture bracket with a vitallium clasp and a preparation method thereof. The removable denture bracket comprises a bracket body, a connecting part and a clasp, wherein the bracket body is prepared from medical titanium metal. The clasp is prepared from vitallium which is cobalt-chromium-molybdenum alloy, wherein the content of cobalt is 63.4%, the content of chromium is 29% and the content of molybdenum is 5.2%. Half of the connecting part and the bracket body are integrated, while the other half of the connecting part and the clasp are integrated. The two halves are welded to connect the bracket body and the clasp. The invention further provides a method for preparing the removable denture bracket. According to the pure titanium removable denture bracket with the vitallium clasp and the preparation method, the clasp is large in elasticity, not easy to break and convenient to machine, and is free from inert gas protection.

Description

technical field [0001] The invention relates to a removable denture bracket and a preparation method thereof, in particular to a pure titanium removable denture bracket with a vitaline clasp and a preparation method thereof. Background technique [0002] The active denture brackets currently used clinically include products made of cobalt-chromium alloys, titanium alloys, resins and gold alloys. Titanium has good corrosion resistance and good biocompatibility, its density is about 1 / 2 that of cobalt-chromium alloy and nickel-chromium alloy, and the weight of the same volume bracket is more than 1 / 2, so the patient is comfortable to wear and reduces The burden of the denture on the abutment and the load-bearing alveolar ridge. Due to the high melting point of titanium, reaching 1668°C, strong activity, and extremely active chemical properties at high temperatures, traditional gas welding and manual arc welding cannot meet the requirements of welding quality. Titanium weldin...
