Abstract
The invention belongs to new material tooth-implanting base station preparing technical field, it is related to a kind of zirconium oxide tooth-implanting base station preparation method, technical process is prepared including slurry, blank forming and microwave sintering totally three steps, CAD/CAM is utilized by transformation toughening using nano-scale chemical pure zirconia, cold conditions isostatic pressing method and microwave sintering process processing and fabricating precision highest and work difference minimum all-ceramic prosthesis and tooth-implanting base station, meet tooth biological requirement and close to natural teeth mechanical strength, sintering only needs surface polishing to can be used after finishing, it is high with intensity, wearability is good, polishability is preferable, coefficient of friction is small, the characteristics of good stability of the dimension and good self-lubricating property, simultaneously, improve the biocompatibility of base station and dummy, rupture strength, fracture toughness, translucency, marginal and aesthetic effect, shorten clinical repair treatment time, reduce medical expense, reach the top standard of international similar technique, at home, outer popularization and application, bring benefit to the mankind.
Description
Technical field：
The invention belongs to new material tooth-implanting base station preparing technical field, it is related to a kind of zirconium oxide tooth-implanting base station preparation side
Method, prepares the zirconium oxide tooth-implanting base station with high reliability, intensity and toughness and low cost, with the kind of alternative metals material
Plant tooth base station.
Background technology：
Defect of dentition, missing are department of stomatology common disease frequently-occurring diseases, and restorative procedure mainly has removable denture, fixed denture and tooth
Plantation；The development of Dental implantion had both indicated the progress of dentistry, also reflects the hair of the subjects such as biology, chemistry and materialogy
Exhibition, is the crystallization that related discipline is interpenetrated, merged；The generation and development of Dental implantion represent people to stomatological aesthetics and function
The pursuit of recovery；From 1960s so far, various implant systems used in modern Dental implantion are that Titanium is made, by
Aesthetic effect is influenceed in the opaqueness of metal base station；A kind of novel high-stability that Chinese patent 201610641885.2 is announced
Property tooth-implanting base station include artificial tooth connecting portion, middle interconnecting piece, lower end connecting portion, artificial tooth connecting portion, middle interconnecting piece, lower end connect
Socket part is that in the vertical direction is sequentially distributed from top to bottom, and being provided with artificial tooth connecting portion is used for the through hole that screw is inserted, and through hole is indulged
To through middle interconnecting piece and extending in the connecting portion of lower end, the diameter of through hole successively decreases successively from top to bottom, artificial tooth connecting portion
Peripheral distribution has the annular projection being adapted to artificial tooth inner surface configuration, and artificial tooth connecting portion is in elongated cylinder structure, annular projection
Provided with spring, the connection end of middle interconnecting piece and lower end connecting portion is in circular arc channel-shaped, passes through the outer surface in artificial tooth connecting portion
Set and spring is set in annular projection, annular projection, there is certain elastic deformation power built with the annular projection of spring；China
A kind of production technology of personalized tooth-implanting base station is comprised the following steps that disclosed in patent 201510431315.6：A, pass through
The outer scanner of mouth carries out imitating the position lock of the planting body in implantation sufferer dentale in three-dimensional data scanning, plaster mold to plaster mold
Upper scan shaft, or, three-dimensional data scanning is carried out to sufferer oral cavity by intraoral scanner, planting body locks scan shaft, b, mouth
Outer scanner or intraoral scanner transmit three-dimensional data to computer, and computer carries out data pair, and c, computer are according to matching somebody with somebody
Carry out denture designing automatic to result, d, computer are by designed artificial tooth data transfer to 3D printer or grinder, 3D
Printer completes artificial tooth 3D printing, and grinder completes the justice after artificial tooth grinding, e, the artificial tooth of 3D printing shaping or milled processed
Tooth can coordinate with the planting body in implantation sufferer dentale；Chinese patent 201310733686.0 discloses a kind of tooth-implanting base
The preparation method of platform, tooth-implanting and tooth-implanting base station, tooth-implanting base station includes being coated with silver ion on base station body, base station body
Layer, tooth-implanting is that planting body is installed on base station body, and the preparation method of tooth-implanting base station is as follows：Prepare AgNO3Weak solution,
