Abstract
The invention discloses glass ceramic with small porosity for dental implant. The glass ceramic is prepared from the following raw materials in parts by weight: 50-70 parts of silicon dioxide, 20-70 parts of magnesium oxide, 30-40 parts of calcium hydrophosphate, 20-30 parts of phosphorus pentoxide, 15-25 pars of silicon carbide, 10-20 parts of zinc, 12-20 parts of polytetrafluoroethylene and 30-40 parts of ethyl cellulose. The preparation method comprises the following steps of: uniformly mixing silicon dioxide, magnesium oxide, calcium hydrophosphate, phosphorus pentoxide, silicon carbide, zinc, polytetrafluoroethylene and ethyl cellulose, melting, heating to 1300-1400 DEG C, and reacting for 2-3 hours; quenching, grinding, screening and performing cold-press molding; and sintering. According to the preparation method, the raw materials are molded to prepare powder, and the glass ceramic is prepared from the powder, so that cracking of a large piece of glass caused by direct molding can be prevented, and the product quality can be improved; the product prepared according to the method has small porosity, is tight without cracking.

Although the research of China's bio-medical material obtains some achievements attracted people's attention, but integral level is the highest, follows the tracks of
Research is many, and source treatment is few.In terms of industrialization, bio-medical material and goods thereof account for the share of world market less than 2%, main
Import to be relied on, product technology structure and level lie substantially in the primary stage.
Biodegradable ceramic refers to that this implant does not cause the feelings of any bad tissue reaction after being implanted to tissue
Progressively dissolve under condition, and replaced by newborn tissue.The biodegradable ceramic of I clinical practice now specifically includes that hydroxyl
Apatite and β mono-calcium phosphate are usually the film as metal implant or porous material.Due to its main component and people
The inanimate matter of bone is close, therefore it is " artificial bone " person.It after being implanted to human body by the metabolism of human body gradually by
Newly-generated tissue replaces, and during as porous material, the porosity of general material is 60～70%, and the microcosmic hole to material
Gap has certain requirement, typically requires hole master 100 cave, and is interconnected between hole.The growth to tissue of this porous
Being highly advantageous, the mineralized tissue of bone can enter with fibrous connective tissue and be filled into and be fixed in the hole of material, this
It is requisite to physiological permanent reparation.But the intensity of this material is low and crisp, it is not suitable for when therefore using propping up
Weight position, because the bending force at these positions, distorting stress can cause the fracture of implant after being delivered to implant.The most often quilt
Alternate material and the filler in bone room for the biggest position of root of the tooth and stress.
Bioactive ceramics first by Hench L.L et al. propose, refer to this material be implanted to internal after can with around
There is biochemical reaction in tissue, so that form bioconjugation between implant and tissue.This mainly include bio-vitric and
Biological glass ceramic composite.The biocompatibility of bioactive ceramics, between inactive ceramic and degradable pottery, has
There is good biocompatibility, have no side effect.Additionally, due to its chemical composition is closely similar with the composition of skeleton,
After being implanted in tissue, the easy and chemical bonding organizing the formation of close and firm of surrounding, or through biodegradable formation
New tissue.The research of bioactive ceramics and clinical practice have become as materialogy, medical science and biochemistry etc. and learn
The study hotspot of section, is increasingly subject to people's attention, particularly some high intensity, machinable glass ceramics pottery and be used for
Functional glass ceramics research and development of therapeutical uses, the medical treatment for the mankind opens new road.Kyoto Univ Japan is little
The Kubo Orthodox Church is invested nineteen eighty-two and successfully be have developed the apatite containing about 38wt% and about 34% wollastonite
(wo1lastonite) devitrified glass, the most usually said A/w glass.This glass not only has preferable mechanical property
Can, and stronger biochemistry can be formed with tissue and be combined.The phosphorite crystal content separated out from glass basis is not
The only mechanical property to material has large effect, and it plays conclusive effect to the biologically active of material.From glass
Matrix separate out crystal grain except having with the raw material of material outside the Pass, the Technology for Heating Processing in crystallization process also has the biggest shadow to it
Ring, it is therefore necessary to the preparation process of material is carried out strict control.Selecting suitable composition and Technology for Heating Processing is to prepare this
Plant the key of material.Machinable bio-microcrystal glass due to its good cutting ability, simultaneously because its milkiness characteristic with from
So enamel is the most close, and quality is fine and close, wear-resisting, any surface finish, good Biocompatibility and chemical stability, therefore exists
All-ceramic crown dummy gains great popularity.The most in recent years, (cAD/cAM) technology is manufactured along with CAD/auxiliary
Popularization and application, open new road for machinable glass ceramic application in oral restoration.In sum, glass base is raw
The compositional system of thing carrier material, substantially still falls within calcium phosphate system composition, but raw not affecting glass ceramics
On the basis of thing compatibility and biologically active, in order to improve the mechanical property of biomaterial, processing characteristics or some other property
Can, the material of other certain component can be added, its consumption is relevant with preparation method and preparation technology.
