Summary of the invention
In order to overcome the deficiency of existing veneer Colorimetric techniques, the invention provides a kind of veneer color board with more than 10 kinds different colours effects, veneer color board is made up of the finished product veneer of more than 10 different colours effects.Preferably, be made up of the finished product veneer of 10 to 60 different colours effects.
The preparation method of veneer color board of the present invention comprises the steps:
(1) spatial digitizer scanning standard model;
(2) veneer of computer design standard type and thickness, design number on veneer, veneer thickness is 0.1mm ~ 1mm;
(3) design data is sent to 3D wax pattern printer and prints resin wax pattern;
(4) embeding resin wax pattern, uses the casting of casting porcelain die casting stove;
(5) polishing, glazing.
Preferred 0.2mm ~ the 0.5mm of veneer thickness in step (2).
The using method of veneer color board of the present invention is as follows:
(1), when using veneer color board, color is tried according to the color of different autologous patient tooth and the matched finished product veneer of effect selection finally wanted;
(2) thickness of finished product veneer is selected according to different tooth richness, the selection 0.5mm ~ 1mm of face type depression, the selection 0.1mm ~ 0.3mm of tooth arrangement compared with normal;
(3) the finished product veneer chosen is placed directly on patient teeth can sees final color effects, select favorite color after multiple effect can be contrasted, then the numbering on corresponding veneer is supplied to skilled worker and formally makes.
Ultra-thin porcelain veneer is because the color of teeth of patient itself can through porcelain veneer when saturating color does dental prosthetics.Color after porcelain veneer is bonding is the final color be made up of autologous patient tooth and porcelain veneer compound.Because the color of each autologous patient tooth is uncertain, porcelain veneer also has multiple color to select, and causes the uncertain of final cosmetic result, is a great problem of dental prosthetics.
Veneer color board designs for the difficult problem solving ultra-thin porcelain veneer colorimetric, according to the thickness of ultra-thin veneer, produces different colours in advance, the porcelain veneer of the standard type of different-thickness.Use veneer color board can make doctor and patient before reparation, just can see the color improvement after repairing in the future.
Veneer color board is made up of the finished product veneer of more than 10 different colours effects, and each veneer has a numbering.When use 10 veneers, be denoted as R0 to R9(and use when being greater than 10, label can the like), represent different colors, comprising fluorescence white effect, ultrawhite effect, natural white effect; Permeability be divided into hide color completely, partly to hide color, highly transparent and minuent transparent; Thickness is 0.1mm ~ 1mm.
When using veneer color board, try color according to the color of different autologous patient tooth and the matched finished product veneer of effect selection finally wanted.Such as: case is severe tetracycline pigmentation teeth or dental fluorosis, color of teeth is very black or very yellow, the whitening mode of the ultra-thin veneer of not grinding one's teeth in sleep of choice for use.Cannot determine the color of autologous tooth with traditional color board, doctor can use veneer color board to carry out colorimetric.If patient wants to make very white color into, the finished product veneer of the ultrawhite effect hiding color will be selected to use; If want to make very natural color into, then the finished product veneer of half screening color or low transparent natural effect can be selected to try out; And the thickness of finished product veneer will be selected according to different tooth richness, selection 0.5mm ~ 1mm that face type caves in serious, tooth arrangement selects 0.1mm ~ 0.5mm normally, and thickness why will be selected to be because the difference of veneer thickness also can cause color to have certain difference.During examination color, the finished product veneer chosen is placed directly on patient teeth and can sees final color effects, select favorite color after multiple effect can be contrasted, then the numbering on corresponding veneer is supplied to skilled worker and formally makes.The effect of the ultra-thin veneer of whitening finally produced after examination color is very easy to make patient satisfaction.By veneer sterilization and reusable after on probation.
The scheme that the present invention takes uses the ultra-thin veneer of finished product to be placed directly on patient teeth to try color when the veneer restorations of tooth-whitening, and make colorimetric easier, color more can meet the demand of patient.
Detailed description of the invention
Below provide preferred embodiment of the present invention, to understand the present invention further, but protection scope of the present invention is not limited in these embodiments.
