Abstract
The invention provides natural protein active cement for restoring teeth. The cement is prepared form the following raw materials: 100 parts of fresh egg shell powder, 80 to 100 parts of fresh egg white and 0.3 to 1 part of astragalus polysaccharides, and is prepared by the following steps of: 1) soaking fresh egg shells in clear water for 30 minutes, washing with clear water for 3 times, drying, crushing and grinding into egg shell powder with the granularity of less than 7 micrometers, and sterilizing by using ultraviolet rays for later use; and 2) quickly mixing the fresh egg shell powder and the astragalus polysaccharides uniformly according to a weight proportion, immediately cementing and restoring the teeth, and solidifying at normal temperature in 5 to 10 seconds to restore the normal functions of the teeth. Compared with the conventional cement, the cement has the following advantages that: all natural edible egg white and egg shells are adopted as raw materials, and components of various materials and main physical and chemical indexes of the materials meet the biological requirement, so the cement has high promotion and application value.
Description
Technical field
The present invention relates to a kind of natural binding material, specifically a kind of dummy or repair materials a kind of natural protein active cement for restoring teeth that bonds to the hard tooth tissue surface.
Background technology
At present; The application of the cement of albumen pure natural in tooth is repaired is still blank; As basic material, exploitation has the pure-natural biological activity, the good tooth of security performance is used and repaired cement with albumen, will be that natural cement is used new field of developing.Because this research project natural activity cement; Be to be basic material with eggshell, Ovum Gallus domesticus album; Raw material is based on cheap and high security, so succeeding in developing and the application in tooth of cement will increase tooth safety of repairing and the cost that reduces the tooth binding material.The research success of this natural novel bonding material will be done the contribution that makes new advances for the tooth reparation, create good economic benefit and social benefit simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of be used for the temporary of dental defect and longer-term filling reparation, the biological activity protein cement of multiple dummies such as bonding inlay, complete crown.
The objective of the invention is to realize that by following mode cement is to be processed by following materials of weight proportions, 100 parts of fresh egg-shell meals, fresh albumen 80-100 part, astragalus polysaccharides 0.3-1 part;
Preparation process is following:
1) fresh eggshell soaked 30 minutes with clear water, flushing with clean water 3 times, and oven dry is pulverized to be ground to below 7 microns and is processed egg-shell meal, through subsequent use behind the ultraviolet disinfection;
2) by weight ratio the fresh egg-shell meal of fresh albumen and astragalus polysaccharides rapid mixing are carried out bonding reparation to the tooth body after evenly immediately, room temperature solidifies in 5 seconds-8 seconds and recovers tooth body normal function.
Excellent effect of the present invention is: the raw material eggshell in the prescription, Ovum Gallus domesticus album, and natural, astragalus polysaccharides is the extract of the important Radix Astragali, and market is on sale, and raw material is easy to get.Cement is applied to the tooth reparation, and cement itself has biocompatibility, to tooth body and dental pulp avirulence and zest, has certain preventing decayed tooth ability.
1) be 1.5Mpa--2MPa to enamel and Dentinal adhesive tensile resistance intensity;
2) bonding speed: cement powder liquid is in harmonious proportion the back and solidifies in second at 5--8, and tensile strength reaches more than 80%, replys masticatory function at once after bonding;
3) mix the protein calcium salt that the back forms, can infiltrate in the fine structure of dentin and dummy and form certain structure power and realize boning reparation with hydrogen bond force, that the lysozyme in the Ovum Gallus domesticus album has is antibiotic, antiviral, hemostasis, detumescence and soft tissue restore funcitons.
4) it is high and lasting enamel, dentin and plastics, pottery or metal to be had a good cohesive force bonding force.
5) chemical stability is good, and water absorption rate is low, do not dissolve within the border at teething ring, and invariant color, ageing resistance is good.
6) physical property is good, and enough intensity is arranged, no volume contraction, and approximate with the tooth thermal coefficient of expansion, rheology is little, and with tooth wear degree basically identical, frangible is not non-heat, electric conductor.
The specific embodiment
Natural protein active cement for restoring teeth of the present invention is to be processed by following materials of weight proportions, 100 parts of fresh egg-shell meals, fresh albumen 80-100 part, astragalus polysaccharides 0.3-1 part;
Preparation process is following:
1) fresh eggshell soaked 30 minutes with clear water, flushing with clean water 3 times, and oven dry is pulverized to be ground to below 7 microns and is processed egg-shell meal, through subsequent use behind the ultraviolet disinfection;
2) by weight ratio the fresh egg-shell meal of fresh albumen and astragalus polysaccharides rapid mixing are carried out bonding reparation to the tooth body after evenly immediately, room temperature solidifies in 5 seconds-10 seconds and recovers tooth body normal function.
Cement of the present invention is to be processed by following materials of weight proportions, 100 parts of fresh egg-shell meals, fresh albumen 85-95 part, astragalus polysaccharides 0.5-0.8 part.
Cement of the present invention is to be processed by following materials of weight proportions, 100 parts of fresh egg-shell meals, 90 parts of fresh albumens, 0.7 part of astragalus polysaccharides.
Fresh egg-shell meal is to be that raw material is processed by new fresh hen egg, Ovum Anas domestica or goose egg.Fresh albumen is selected the Ovum Gallus domesticus album of new fresh hen egg, Ovum Anas domestica or goose egg for use.
