Description

High-grade polyest glass binder for beautification of tooth

The present invention is a high-grade polyest glass binder for beautification of tooth, it be a kind of be the main multi-purpose novel tooth section cement that has concurrently with the dental prosthetics, be called for short the J-L cement, its main body prescription is the complex polyester that is formed by the various kinds of resin mixed preparing, and forms through the milkiness sial glass dust of formulated.

The present invention is owing to adopted physicochemical property, the fabulous multiple material of biocompatibility is a material, and adopt means such as multiple bonding mode and room temperature fast-curing, produced higher adhesive strength after making the J-L cement cures, polymerization hardness and abrasion resistance, fabulous corrosion resistance ageing resistance and biocompatibility are arranged, because the color after the J-L cement cures is very true to nature, and it is nontoxic, tasteless, add that it is simple to operate, easy to use, of many uses, multiple advantage such as cheap proves through the many cases clinical trial, and the J-L cement is that adhesives is modified in the beauty treatment of very ideal both at home and abroad at present novel senior tooth section.

In the current more both at home and abroad bonding filling repair materials of tooth section, its typical material has photosensitive resin, EB resin, polycarboxylic acid resin, glass ionomer cement, zinc phosphate cement and some phosphoric acid silicon, zinc oxide eugenol etc.But because color is bad, adhesive strength and hardness are not enough, and corrosion resistance ageing resistace multiple reason such as do not pass a test, and make most materials only not be used in the filling and the bonding aspect of tooth as tooth section beauty treatment decorative material.And tooth section beauty treatment material only photosensitive resin is a kind of because the required condition strictness of this material, the using method complexity, as this material before use must the acid etching drying etc. the tooth body of strictness prepare, during curing at 3000-4000 that solidification device sent

Irradiation under ultraviolet ray could solidify down, cured thickness once only is 1-5 μ m.And in adhesive strength, aspects such as degree of aging and color are not ideal.Coming unstuck in one month according to statistics accounts for 6.3%, and coming unstuck in half a year, accounting for came unstuck in 18%, one year accounts for 30-40%.Owing to cost an arm and a leg, use multiple shortcomings such as limitation again, thereby greatly limited the range of application of photosensitive resin.

In order to make the J-L cement become a kind of being widely used, the performance perfection, the bonding decorative material of tooth section satisfactory for result for the pluses and minuses of above various materials, through meticulous selection and trial-production repeatedly, has been prepared the J-L cement. It is outstanding four characteristics mainly.

(1) bonding characteristics: the J-L cement utilizes the epoxy resin in the complex polyester, the sticking symbol chemical combination of polycarboxylic acids glass and silane, and the recessed embedding effect of resin, make the consolidated structures of J-L cement and integral adhesive structure very reasonable, formed with chemical bonded refractory and be combined into main bonding characteristics.

(2) construction features: the construction features of J-L cement is to adopt the polymerization of complex polyester, complex polyester combines with glass dust, in the presence of copolymer cross-linking agent, make common filler participate in the formation of structure, thereby cohesiveness, hardness, abrasion resistance and flexural strength between the molecule have been strengthened widely, increased the light stabilizing power, improved ageing resistance, increased the service life.

(3) color characteristics: the filler of J-L cement is compared with ceramics owing to adopted milkiness sial glass dust, and milkiness sial glass dust has good luminous reflectanc and covering power and ultraviolet absorption ability.So the color after J-L cement cures under the cooperation of pigment is very good true to nature.

(4) handling characteristics, J-L cement adopt the room temperature fast-curing method for the ease of long-term storage, and cement is made into powder, liquid type and two paste type, time spent powder, liquid mixed by 2: 1, two paste types mixed and can use by 1: 1, met doctor of tooth section and technician's use habit, and are very convenient.

The purposes of J-L cement is very extensive; it can be used on all kinds of damaged teeth; the repairing filling of all kinds of nests hole and dental caries; can be used for the bonding of artificial tooth, orthosis, the required bonding agent of a veneer and a cutting section; especially to all kinds of xanthodont; fluoro spot tooth, tetracycline pigmentation teeth, fall from the sky or outer space hole tooth and all kinds of dental caries have fabulous cosmetic result and protective effect.

The J-L cement can be outstanding the domestic and international so far photosensitive resin that occurs of replacement, the EB resin, glass ionomer cement, poly-sour ceramic cements, filling, beauty treatment repair materials that silver amalgam (bidery metal) and some other tooth sections are used, it is very ideal at present novel dental material.

The J-L cement also can be used for glass, pottery, and some resin material and some metal material is bonding.

The J-L cement divides powder liquid type and two kinds on two paste types, and every kind of concrete prescription is as follows.
