Description
Technical field
The present invention relates to a kind of dental prosthetic composite and preparation method thereof.
Technical background
Tooth is the organ of mankind's laboratory rodent chow.Tooth is the hardest organ of human body.Generally speaking, tooth is in white (the slightly micro-yellow of normal person), and quality is hard.Human language pronunciation is closely related with front-seat upper and lower tooth in mouth.And China's caries prevalence rate is higher, China had carried out repeatedly oral health surveys in recent years, and survey result shows: China's 5 years old child's Primary Caries rate and 12 years old, 35 ~ 44 years old and 65 ~ 74 years old permanent teeth caries prevalence rate are 66%, 28.9%, 88.1% and 98.4% respectively.Usually need to carry out dental filling reparation.Before dental filling, dentist comprehensively can check patient oral cavity, comprehensively understands and suitable process the oral healthy condition of patient, and according to the quantity of patient's dental caries, treat position, the lesion degree of dental caries formulates best dental filling recovery scenario.Dental filling comprises cavity preparation and filling two key steps, and after cavity preparation is good, isolation saliva, sterilization nest hole, allotment filler is inserted in nest hole, immediately carves profile, and removing exceedes the too high part of occlusal surface, in order to avoid cause iatrogenic Occlusal Trauma.After filling tooth material filling, dentist can carry out polishing to dental filling surface, in case filling tooth material is painted, can clean timely the residue remained in after dental filling in dental surface and oral cavity simultaneously.The dental caries of some patient is comparatively large, needs the reparation carrying out corona after dental filling, and dentist can carry out detailed doctor's advice explanation to patient simultaneously.Filling tooth material has silver amalgam, composite resin, glass ionomer etc.Wherein firm, the not easily consume but attractive in appearance not of silver amalgam, composite resin is attractive in appearance, close to the natural color of tooth, but intensity is not as silver amalgam, easy loss, and glass ionomer is mainly used in deciduous teeth and repairs.Aesthetic effect along with teeth repairing material more and more receives the concern of people, and the application prospect of composite resin is very widely thus.In recent years, around these defects of composite resin, a large amount of research work is from free of discontinuities, but the shortcoming such as the mechanical performance of composite resin poor and polymerization shrinkage relative to wearability is also the principal element limiting its broader applications always.In most of the cases, the surface chemistry composition of existing composite resin material is difficult to meet above-mentioned requirements with structure, usually will adopt surface modification treatment, as graft copolymerization, to improve its performance.In addition, material also needs excellent processing forming, is easily processed into the complicated shape of needs.So need the resin material of the reparation tooth developing the good mechanical performance such as a kind of strength of materials, hardness, wearability, durability and toughness.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of dental prosthetic composite and preparation method thereof is provided.
The object of the invention is to be achieved through the following technical solutions: a kind of dental prosthetic composite, be made up of the component of following weight: polyethylene 20-40 part, xanthan gum 25-40 part, calcium hydroxy phosphate 20-25 part, chitosan 2-8 part, tributyl citrate 1-6 part, consisting of phase-transferring agent 4-8 part, divinyl tetramine 2-6 part, 2-methyl-2-acrylic acid-2-(phosphono oxygen base) ethyl ester 25-35 part, actol 4-8 part, titanium dioxide 7-20 part, silica 1 0-15 part, antioxidant 3-8 part, hydroxyanisol 4-8 part, calcium monofluorophosphate. 1-13 part, ethanol 8-23 part, distilled water 25-45 part.
