Embodiment Construction

[0029] The method of 3D printing personalized artificial teeth with artificial bone material fusion deposition molding of the present invention comprises the following steps:

[0030] (1) Preparation of polyether ether ketone suspension

[0031] Take medical grade PEEK powder and mix it with glycerin and ethanol. Glycerin is used as dispersant and ethanol is used as solvent. Mix 10g PEEK with 45ml glycerin and 45ml ethanol to form a 10% PEEK suspension , and then grind it into polyether ether ketone suspension by high-speed grinder for later use.

[0032] In this step, if the X-ray developing property needs to be improved, 1-5% barium sulfate powder can also be added when mixing.

[0033] (2) Preparation of hydroxyapatite whisker suspension

[0034] Take sub-nanometer hydroxyapatite short whiskers with a diameter of 0.1-1 μm and a length of 100-200 μm and mix them with glycerin and ethanol. Glycerin is used as a dispersant and ethanol is used as a solvent. Mix 45ml of glycerin...

Abstract

The invention provides a method for melting deposition molding 3D printing of a personal artificial tooth with an artificial bone material. The method comprises the following six steps: preparing a polyether-ether-ketone suspension, preparing a hydroxyapatite crystal whisker suspension, compounding an artificial bone material, performing three-dimensional molding design on an artificial tooth, performing melting deposition molding 3D printing on the artificial tooth and an artificial tooth planting guide plate, performing surface treatment on a planted part of the artificial tooth, and the like. As polyether-ether-ketone and hydroxyapatite crystal whiskers are adopted to compound an artificial bone material as a raw material for the artificial tooth, the artificial tooth is printed by adopting a melting deposition molding 3D printing manner, and furthermore surface treatment is implemented to expose a hydroxyapatite crystal whisker fiber head on the surface of the planted part of the artificial tooth, significant promotion functions on adhesion, proliferation and differentiation of cells are achieved. By adopting the method, personal artificial teeth can be rapidly made and planted, the cost can be minimized, and the operation is safe. The artificial tooth made with the method is relatively good in biocompatibility and bone junction strength when being compared with common artificial teeth.

Description

technical field [0001] The invention relates to a method for preparing artificial teeth, in particular to a method for 3D printing individualized artificial teeth by fusion deposition molding of artificial bone materials, and belongs to the technical field of dental medical material preparation. Background technique [0002] When adults suffer from periodontitis or advanced dental caries, the teeth will become loose and cannot be used any longer, seriously affecting eating, and tooth extraction is required. After tooth extraction, artificial teeth should be replaced in the corresponding position in time. The purpose is to make functional artificial teeth To replace the stimulation of natural teeth on the alveolar bone transmission force, to prevent disuse atrophy of alveolar bone. At present, there are three kinds of implant methods: immediate implant, conventional implant and delayed implant. Immediate implantation refers to the method that the patient immediately inserts ...
