Abstract
A titanium alloy porcelain false front tooth comprises a titanium alloy crown body and a porcelain body, wherein the titanium alloy body is 0.25 to 0.3 mm in thickness; the porcelain body comprises a first masking layer, a second masking layer and a body porcelain layer; the first masking layer is attached to the surface of the titanium alloy crown body through sintering and melting, and is thicker than the second masking layer; the lip side of the body porcelain layer, which is near the root of the titanium alloy crown body, is 1.1 to 1.4 mm in thickness; the tooth side of the body porcelain layer is 0.6 to 0.9 mm in thickness; the thickness of the body porcelain layer becomes larger and larger from the root part to the incisal edge part; the incisal edge part of the body porcelain layer is 1.6 to 1.8mm in thickness. As the titanium alloy crown body is adopted, the strength of the titanium alloy porcelain false front tooth is enhanced than that of a false front tooth adopting a titanium crown body. Therefore, the titanium alloy crown body can be thickened, and the body porcelain layer can be thinned, which reduces processing difficulty; as the sintering thickness is thinned during the sintering process of the porcelain body, porcelain cement can be melted and attached to the titanium alloy crown body better, phenomena such as cracking can be reduced, and the service life is prolonged.
