Embodiment 1

[0031] Embodiment 1 provides a method for making pure titanium teeth, using chemical components: titanium, aluminum, alum, nitrogen, carbon, hydrogen, iron, oxygen, and with a yield strength of 950MPa, a tensile strength of 1005Mpa, and 10% Elongation, elastic modulus of 115Mpa, 4.5g / cm 3 Density, melting point range of 1604-16551, 10.16×10 -6 K -1 The expansion coefficient is used to make pure titanium teeth.

[0032] Wherein, the color of the titanium metal tooth prepared by adopting the manufacturing method of the pure titanium tooth can be white or silvery white.

[0033] Among them, the pure titanium tooth is printed by 3D printing technology

[0034] Among them, the proportion of titanium, aluminum, alum, nitrogen, carbon, hydrogen, iron and oxygen used in the production method of pure titanium teeth can be: titanium, 90%; aluminum, 6%; alum, 4%.

Abstract

The invention provides a making method of a pure titanium tooth, and a method for autotransplanting by means of the pure titanium tooth. The pure titanium tooth is made from Ti, Al, V, N, C, H, Fe and O under the following conditions: the yield strength is 950MPa, the tensile strength is 1005Mpa, the elongation rate is 10%, the elastic modulus is 115Mpa, the density is 4.5g / cm<3>, the melting point range is 1604-16551, and the expansion coefficient is 10.16*10<-6>K<-1>, and the pure titanium tooth having a same shape with a transplantation tooth, printed through a 3D printing technology, is placed in the pre-produced tooth socket of a transplantation site; and the transplantation tooth is used to substitute the pure titanium tooth in the tooth socket after a predetermined time quantum. The method can avoid transplantation tooth periodontal membrane injuries, reduces the inflammation reactions in the transplantation site, and can establish normal periodontal tissues to avoid external root resorption.

Description

technical field [0001] The invention belongs to the fields of oral and maxillofacial surgery and orthodontics, and in particular relates to a method for making pure titanium teeth and performing autologous tooth transplantation by means of pure titanium teeth. Background technique [0002] At present, autologous tooth transplantation is a good method for repairing dentition defects. The success of the operation is related to many factors, such as the shape of the root of the transplanted tooth, the amount of bone in the transplanted area, minimally invasive tooth extraction, and the degree of root canal treatment. However, after transplantation of teeth with complete root development, pulp necrosis and root resorption often occur, resulting in failure of transplantation. In this case, root canal treatment within 3 weeks after implantation can avoid root resorption due to pulp infection. However, root canal treatment cannot avoid external root resorption caused by infection ...
