Description
Technical field
The present invention relates to scientific research and Related product Technical Development Area, more particularly to a kind of Oral Science is repaiied with tooth
Multiple new product and preparation method thereof.
Background technology
Dental prosthetics is on the basis of the tissue of tooth destroyed or seriously undermined is removed, according to maintenance, drag
And the principle of protection dental pulp-dentine organ prepares tooth, finally, with certain material by its intrinsic shape of certain program recovery
State and function.The reason for causing defect of teeth is mainly carious tooth, is secondly wound, abrasion, acid etching etc..Restorative procedure can be according to tooth
Body defect situation and material context is used, from resin reparation, All-ceramic restoration, Ceramic prosthesis etc..
Resin reparation is referred to because carious tooth, wedge-shaped defect, wound etc. cause tissue of tooth defect person, using composite resin material
Repaired, to recover its profile and function.Tooth after filling is true to nature, does not almost see it being patched.Resinae is filled
Material can be used for before and after tooth, claim creamy white material, resin reparation to depend on good vertex-gluing graph technology.Resin repairs minimally invasive,
It is true to nature, high intensity, but complicated process of preparation, price height.
All-ceramic restoration is the general designation repaired without metal porcelain, and dummy does not use metal, and adopts close with color of teeth
High strength china material make, therefore full porcelain tooth is more attractive compared with Ceramic dental prosthetic restoration with metal base, and translucence is approximate with natural teeth,
Gingival edge performance is more natural after reparation, can reach simulated effect, and have the advantages that it is non-stimulated to perienchyma, it is wide
It is general for clinic.But need the full porcelain Computer Aided Design of computer and machining system, complex process.
Ceramic prosthesis are that porcelain powder melts the Full Crown be preced with surface and formed in attached and metal through high temperature sintering.The program
Related adjacent teeth (abutment) tooth body removing amount is big in counterpart, there is certain manufacture difficulty.Abutment and mucous membrane tissue are easily brought to patient
Damage, dental caries and periodontitis, alveolar ridge absorbs, temporomandibular joint illness.
Patent 201510638481.3 discloses a kind of teeth repairing material and preparation method thereof, and teeth repairing material includes
The raw material of following weight portion meter：20～60 parts of calcium carbonate, 30～50 parts of Corvic, 20～50 parts of cobalt dioxide, a poly- left side
40～80 parts of lactic acid of rotation, 10～20 parts of calcium hydroxy phosphate, 20～40 parts of magnesium dihydrogen phosphate.Its preparation method is：By calcium carbonate, gather
Grind after vinyl chloride resin, cobalt dioxide, PLLA, calcium hydroxy phosphate, magnesium dihydrogen phosphate mixing and uniformly obtain compound；
The compound is melted at a temperature of 1800～2000 DEG C, makes the batch component be evenly distributed and after bubble overflows completely
Annealed, you can.Although the teeth repairing material has higher intensity, it is used as teeth repairing material, is held
Abutment and mucous membrane tissue damage, dental caries and periodontitis, alveolar ridge is easily brought to absorb, temporomandibular joint illness etc..
