Description
Technical Field
The invention relates to the technical field of oral cavity restoration bodies, in particular to a method for manufacturing polyether-ether-ketone oral cavity restoration bodies with different colors through integrated 3D printing.
Background
The clinical selection of the traditional oral cavity repairing material is still limited to the old three types (resin, metal and ceramic), and the three materials have the limitations and cannot meet the clinical requirements. The color of the resin is close to that of natural teeth, the aesthetic property is good, but the resin material has low hardness, is easy to age, is easy to abrade natural teeth of the jaw, has the problems of micro-leakage and the like, and is less and less in clinical application though continuous material improvement; the metal material has the advantages of high strength, corrosion resistance, good fatigue resistance and the like, but has the defects of unattractive color, high hardness (easy to wear and tear to natural teeth of the jaw) and the like; in recent years, patients have better aesthetic requirements, and some patients reject the selection of metal materials (factors such as sensitivity to metal odor, metal allergy and negative influence of metal on nuclear magnetic resonance examination), so that the nonmetallic oral cavity repairing material is becoming the mainstream of clinical material selection.
The current ceramic is the most representative inorganic non-metallic repair material, and has the advantages of beautiful color and good biocompatibility, and the defects of great brittleness, easy damage and high price, so that the clinical indications of the ceramic are greatly limited (for example, the ceramic cannot be used for repairing removable dentures); at present, the ceramic materials which are commonly used clinically are mainly glass ceramic and zirconium dioxide ceramic materials, but the hardness and the elastic modulus of the ceramic materials are far greater than those of natural teeth, the ceramic materials are easy to abrade the natural teeth of the jaw, and the clinical effect of the prosthesis is influenced by the overweight of the prosthesis.
Polyetheretherketone (PEEK) is a special engineering plastic with excellent properties such as high temperature resistance, self-lubrication, processed performance and high mechanical strength, and can be manufactured and processed into various mechanical parts; the PEEK material has the following performance advantages: compared with resin materials, the high-strength wear-resistant and wear-resistant composite material has good strength, and is durable and wear-resistant and ageing-resistant; compared with metal materials, the material has the advantages of large space for improving aesthetic properties, excellent biocompatibility and semi-radiation resistance; compared with ceramic materials, the material toughness is far better than that of ceramics, the weight is lighter and the cost is lower; the PEEK material is limited to be prepared into a monochromatic restoration in the field of oral restoration, the processing technology only comprises the processes of milling, injection molding and the like, 3D printing of the PEEK for preparing the oral restoration is not reported clinically, the appearance color of the existing pure PEEK material is light brown, the existing pure PEEK material is not suitable for directly preparing the oral restoration, and the color of the existing pure PEEK material needs to be improved so as to meet the clinical requirement of oral aesthetic restoration; in addition, the existing processing method for using PEEK as the dental prosthesis mainly comprises the traditional injection molding pressing and digital milling methods, wherein the processing procedure of the traditional injection molding pressing and digital milling methods is complicated, time and labor are wasted, and the traditional digital milling methods have large material waste and are not suitable for forming a finished product with a complex thin-wall shape. The 3D printing is an ideal method for realizing the low-cost quick manufacture of a single finished product with a complex shape, and how to apply the advanced 3D printing technology to print the PEEK dental restoration is a hot problem in the field.
