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). It is a permanent inorganic non-metallic repair material, which has the advantages of beautiful color and good biocompatibility, but the disadvantage is that it is brittle, easy to break, and expensive, so its clinical indications are greatly limited (for example, it cannot be used for the repair of removable dentures)
At present, the ceramic materials commonly used clinically are mainly glass ceramics and zirconia ceramic materials. However, the hardness and elastic modulus of ceramic materials are far greater than those of natural teeth, which are easy to wear the natural teeth of the opposite jaw. At the same time, the weight of the restoration also affects its clinical effect
[0003] In addition, the production of traditional restorations requires intraoral impressions, and most patients will feel discomfort or even nausea and vomiting

Embodiment 1

[0039] This embodiment provides a method for manufacturing a digital PEAK base material restoration, including the following steps:

[0040] S1: Scan the patient's mouth with a scanner model 3shapeD2000, obtain the digital model of the patient's maxilla and mandible, and obtain the occlusal relationship. For the obtained digital model, see figure 1 ;

[0041] S2: Based on the obtained digital model and combined with 3 Shape Dental Manager Client design software, a digital restoration model is designed, and the digital restoration model is trimmed and undercut designed. After the design is completed, the occlusal condition is checked, and then the restoration is designed. The bonding surface used for bonding with the tooth is designed to improve the specific surface area and surface roughness of the micro-texture to form a roughened surface, wherein the micro-texture includes a number of bumps and grooves arranged on the bonding surface. or bumps and grooves, which can be of r...

Embodiment 2

[0052] This embodiment provides a method for manufacturing a digital PEAK-based restoration, which is different from Embodiment 1 in that: when designing the numerical model of the restoration, micro-textures are also designed on the outer surface of the restoration, and then After the restoration is printed out by 3D printing, the outer surface of the restoration is subjected to polymerized porcelain baking so that the restoration can be used as an inner crown. 3D printing the micro-texture on the bonding surface of the inner crown and the tooth can improve the bonding performance of the inner crown and the tooth, and the micro-texture on the outer surface of the inner crown can improve the connection stability of the polymer porcelain.

Embodiment 3

[0054] This embodiment provides a method for manufacturing a digital PEAK base material restoration, including the following steps:

[0055] S1: Scan the patient's mouth with a scanner model 3shapeD2000, obtain the digital model of the patient's maxilla and mandible, and obtain the occlusal relationship. For the obtained digital model, see figure 1 ;

[0056] S2: Based on the obtained digital model, combined with 3 Shape Dental Manager Client design software to design a digital restoration model, trim the digital restoration model, fill in the undercut design, check the occlusion after the design is completed,

[0057] S3: Prepare a prosthetic material, which contains 5-20% of titanium dioxide by volume, 1-10% of iron oxide by volume, and the rest is PEEK material. After preparation, a base material is formed, and then it is cut by Wieland si cutting equipment Substrate, to make a restoration, see figure 2 ;

[0058] S4: Cut the bonding surface of the restoration for bondi...

Abstract

The invention discloses a manufacturing method of a digital PEAK substrate restoration. The manufacturing method includes the following steps that S1, the oral cavity of a patient is scanned with a scanner, a digital model of the upper jaw and the lower jaw of the patient are obtained, and an occlusion relationship is obtained; S2, based on the digital model in combination with design software, adigital restoration model is designed; and S3, PEEK / PEKK materials are in combination with a digital restoration model to manufacture the restoration. The invention further discloses a bonding methodof the digital PEAK substrate restoration with a tooth body. The digital scanning technology is used for scanning to obtain the digital model of the oral cavity of the patient, the discomfort caused to the patient by a traditional model obtaining method is solved, the treatment effect is ensured, and in addition, the restoration made of the PEEK / PEKK materials has the advantages such as good strength, durable wear resistance, aging resistance, large space for improvement in aesthetic performance, excellent biocompatibility, semi-blocking radiation, light weight and low cost.
