Technical Field

The invention relates to the technical field of oral restoration, in particular to a manufacturing method of a digital PEAK base material restoration and a bonding method of the restoration and a tooth body.

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 are rejected by selection of metal materials (such as sensitivity to metal odor, metal allergy and negative influence of metal on nuclear magnetic resonance examination), the non-metallized oral cavity repair material is becoming the mainstream of clinical material selection, and currently, ceramics is the most representative inorganic non-metal repair material, and has the advantages of beautiful color and good biocompatibility, has the defects of high brittleness, easy breakage and high price, and greatly limits the clinical indications (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.

In addition, the production of traditional prostheses requires intraoral impression taking and most patients experience discomfort and even nausea and vomiting.
