Embodiment 1

[0030] The step (4) 3D printing generates the denture prosthesis by accumulating and printing layer by layer from bottom to top, and a gradual filling rate of 10% for each layer is used during the accumulative printing, that is, the density will gradually increase from bottom to top.

[0031] The particle size of the titanium-zirconium alloy powder in the step (4) is 60-70nm, and the particle size of the nanometer powder is 60-80nm.

[0032] The mass ratio of the mixed powder of magnesium oxide and aluminum oxide is 1:9.

Abstract

The present invention provides a technology for repairing dentures by using a 3D printing titanium-based composite material. The technology combines 3D printing with an existing digital technology anda new titanium alloy formula is used to solve problems that existing fixed denture restorations are high in porcelain-falling rate and poor in binding with human body tooth tissues.

Description

technical field [0001] The invention relates to the field of denture restoration methods, in particular to a technique for repairing dentures using 3D printed titanium-based composite materials. Background technique [0002] The existing fixed denture restorations mainly use digital technology for fixed restoration of titanium metal, which mainly includes: model trimming, scanning design, CAD / CAM cutting metal CRM printing, surface treatment, car porcelain modification, glazing and dyeing and other technological processes, but The existing fixed denture restorations have a high rate of ceramic chipping and poor integration with human tooth tissue. Contents of the invention [0003] The purpose of the present invention is to provide a process for repairing dentures using 3D printing titanium-based composite materials, combining 3D printing with existing digital processes, and adopting a new titanium alloy formula to solve the problems of existing fixed denture restorations,...
