Problems solved by technology

[0002] The clinical selection of traditional oral restorative materials is still limited to the "old three" (resin, metal, ceramics), each of which has its own limitations and cannot meet clinical needs
The color of the resin is close to that of natural teeth, and the aesthetics are good. However, the resin material has low hardness, is easy to age, is easy to be worn by the natural teeth of the opposite jaw, and has problems such as micro-leakage. The less; metal materials have the advantages of high strength, corrosion resistance, and fatigue resistance, but the disadvantages are unsightly color and high hardness (easy to wear the natural teeth of the opposite jaw); in recent years, patients have better aesthetic requirements, and Some patients reject the choice of metal materials (sensitivity to metal odor, metal allergy, and the negative impact of metal on MRI examinations, etc.), "non-metallized oral restoration materials" are becoming the mainstream of clinical material selection
[0003] At present, ceramics are the most representative inorganic non-metallic repair materials, which have the advantages of beautiful color and good biocompatibility, but are brittle, easy to break, and expensive, which greatly restricts their clinical indications (for example, they cannot be used in Removable dentures); At present, the ceramic materials commonly used clinically are mainly glass ceramics and zirconia ceramic materials, but the hardness and elastic modulus of ceramic materials are far greater than natural teeth, and it is easy to wear the natural teeth of t

Embodiment 1

[0025] This embodiment discloses an integrated 3D printing method of polyether ether ketone dental restorations in different colors, which includes the following steps:

[0026] S1: Use a digital oral scanner to scan the surface morphology of the patient's upper and lower jaws, obtain digital three-dimensional model data of the patient's upper and lower jaws, and obtain the occlusal relationship between the upper and lower dentitions;

[0027] S2: Import the acquired three-dimensional data into the digital denture design software, and use the three-dimensional data as the basis to design different parts of the digital dental prosthesis and adjust the overall occlusal relationship to obtain a three-dimensional data model of the dental prosthesis;

[0028] S3: Separate the three-dimensional data model of the teeth and gingival parts of the dental restoration, and design the connection interface to obtain the printing data of the teeth and gingival parts, and then import the printing dat...

Embodiment 2

[0042] The teeth and gums of the oral restoration involved in this embodiment are both made of polyether ether ketone restoration materials; wherein the polyether ether ketone tooth color material includes polyether ether ketone and toner powder. The powder is one of titanium oxide, zirconium oxide, and aluminum oxide, and the mass percentage of the toner powder is 2%-20%; the polyetheretherketone gum color material includes the following components: polyetheretherketone, iron oxide, The mass percentage of iron oxide is 0.2%-1.2%.

[0043] This embodiment relates to a polyetheretherketone dental restoration tooth color shader and a gum color shader;

[0044] Among them, the polyether ether ketone dental restoration tooth color palette includes nine color standard plates from Dentin-A to Dentin-I. Among them, the DA color standard plate is mixed with polyether ether ketone and 3% titanium oxide by mass. The DB color standard plate is made of polyether ether ketone and 10% by mass o...

Abstract

The invention discloses a method for integrated 3D printing of polyether-ether-ketone oral restorations with different colors. The method comprises the following steps: S1, acquiring the upper jaw andthe lower jaw of a patient, acquiring digital three-dimensional model data of the upper jaw and the lower jaw, and acquiring an upper dentition and lower dentition occlusion relationship and personalized tooth colors and gingival colors of the patient; S2, on the basis of the three-dimensional data in S1, designing a digital dental restoration and adjusting the occlusal contact relationship between the digital dental restoration and the jaw teeth to obtain a three-dimensional data model of the final restoration; S3, according to different tooth colors and gingival colors, separating the three-dimensional data model tooth of the restoration is separated from the gingival part to obtain printing data of different parts of the dental restoration body and importing the printing data into 3D printing equipment; and S4, respectively determining colors (tooth color and gingival color) of each part of the restoration, carrying out proportioning respectively, and conveying the date to two printing heads of the integrated 3D printing equipment, and carrying out integrated printing to obtain a final dental restoration material object.

Description

Technical field [0001] The present invention relates to the technical field of oral restorations, in particular to a method for manufacturing polyetheretherketone oral restorations of different colors by integrated 3D printing. Background technique [0002] The clinical choice of traditional dental restorative materials is still limited to the "oldest three" (resin, metal, ceramic), and the three materials have their own limitations and cannot meet clinical needs. The color of the resin is similar to that of natural teeth, and the aesthetics is better. However, the resin material is low in hardness, easy to age, easily worn by the natural teeth of the opposite jaw, and has problems such as micro-leakage. Although continuous material improvements have been made, it has been increasingly used in clinical applications. The less; the metal material has the advantages of high strength, corrosion resistance, and good fatigue resistance, but the disadvantages are that the color is not b...
