Abstract
The invention provides a manufacturing method for a tooth repairing paster based on a computer aided design (CAD) technology and a rapid prototyping (RP) technology. The method comprises the following steps of: a, acquiring tooth model data of a patient by a three-dimensional laser scanning technology; b, designing a digital model of the tooth repairing paster through three-dimensional software according to the model data; c, manufacturing a resin cast of the tooth repairing paster by the rapid prototyping technology according to the digital model of the tooth repairing paster; d, manufacturing a porcelain tooth repairing paster by a porcelain casting technology according to the resin cast; and e, turning the porcelain tooth repairing paster, and polishing or glazing the porcelain tooth repairing paster to obtain the finished product of the tooth repairing paster. By the method, the tooth repairing paster is manufactured by the CAD technology and the RP technology, so the production efficiency, precision and accuracy of the tooth repairing paster are improved.
Description
Technical field
The present invention relates to technical field, particularly a kind of manufacture method of repairing paster based on the tooth of CAD and RP technology.
Background technology
It is a kind of novel dental prosthesis that tooth is repaired paster; It can effectively improve the situation not attractive in appearance of the former thread form attitude of patient, color and arrangement etc. through pasting the ultrafine porcelain paster of one deck in patient's exterior of teeth, and is few to the injury of patient's tooth body; Easy to use, effect is remarkable.But it all is on the basis of manual wax pattern, to carry out production and processing that traditional tooth is repaired paster, and efficient is lower, and degree of accuracy is not high, and repairing effect is undesirable.
In recent years; CAD (Computer Aided Design; Computer-aided design) technology has all obtained development fast in the every profession and trade field; This wherein is also included within the application in the medical field, but the application in Oral Repair is less relatively, and research, the application of particularly repairing in the paster processing at tooth relatively lag behind.
RP (Rapid Prototyping; Quick shaping) technology is an advanced manufacturing technology that grows up nineteen nineties; It is based on discrete/stack shaping principle; Can three-dimensional design data directly be turned materially the product prototype with certain structure function, applying of RP technology can be shortened new product development cycle greatly, reduces development cost, improved development quality.The RP technology is having a wide range of applications and development space aspect the making of mouth mending material, particularly repairs in the making of resin casting mold of paster at tooth.
In the prior art, do not utilize technological combining with cad technique of RP made tooth reparation paster.
Summary of the invention
The present invention provides a kind of manufacture method of repairing paster based on the tooth of CAD and RP technology, improved tooth repair paster production efficiency, precision and accuracy.
To achieve these goals, the present invention provides following technical scheme:
A kind of manufacture method of repairing paster based on the tooth of CAD and RP technology, it may further comprise the steps:
A. patient's tooth model data of utilizing three-dimensional laser scanning technique to gather;
B. repair the mathematical model of paster according to said model data and through three-dimensional software design tooth;
C. repair the mathematical model of paster and make the resin casting mold that tooth is repaired paster according to said tooth through rapid shaping technique;
D. repair paster according to said resin casting mold through the tooth of the porcelain of casting porcelain fabrication techniques;
E. the tooth of said porcelain being repaired paster carries out the car porcelain, polishes then or glazing obtains the finished product that tooth is repaired paster.
Preferably, said step c specifically comprises:
(1) will design the tooth of accomplishing with computer aided design software and repair the file that the data model of paster exports as the STL form;
(2) file with the STL form imports the 3 D stereo printer, and the resin that applying three-dimensional three-dimensional printing machine and supporting quick shaping are used forms and obtains the resin casting mold that tooth is repaired paster.
Through implementing above technical scheme, have following technique effect: method provided by the invention, make tooth through CAD and RP technology and repair paster, improved tooth repair paster production efficiency, precision and accuracy.
The specific embodiment
Technical scheme is for a better understanding of the present invention described embodiment provided by the invention below in detail.
The embodiment of the invention provides a kind of manufacture method of repairing paster based on the tooth of CAD and RP technology, may further comprise the steps:
A. patient's tooth model data of utilizing three-dimensional laser scanning technique to gather;
These patient's tooth model data are the three-dimensional data of this patient's tooth model, and this three-dimensional data can accurately represent patient's tooth form and size.Concrete, use spatial digitizer that the former tartar cream of the clinical patient who obtains model is scanned, obtain the three-dimensional data of patient's tooth.
B. repair the mathematical model of paster according to said model data and through three-dimensional software design tooth;
Described mathematical model is that the three-dimensional data with patient's tooth model is the personalized design that carry out on the basis, with the true form and the size of compound patient's tooth.Concrete, the Autocad that uses a computer imports the three-dimensional data of patient's tooth, and on corresponding tooth position, carries out the design that tooth is repaired the mathematical model of paster.
C. repair the mathematical model of paster and make the resin casting mold that tooth is repaired paster according to said tooth through rapid shaping technique;
The resin casting mold that described tooth is repaired paster is that the data model that rapid forming system is repaired paster according to the tooth that designs among the above-mentioned steps b carries out molding, can digitized data model be reduced to physical model that is:, specifically comprises:
(1) will design the tooth of accomplishing with computer aided design software and repair the file that the data model of paster exports as STL (the applied normative document type of rapid prototyping system at most) form.
(2) file with the STL form imports the 3 D stereo printer, and the resin that applying three-dimensional three-dimensional printing machine and supporting quick shaping are used forms and obtains the resin casting mold that tooth is repaired paster.
D. repair paster according to said resin casting mold through the tooth of the porcelain of casting porcelain fabrication techniques;
That is: the resin casting mold that uses casting porcelain technology that tooth is repaired paster is processed and is obtained the porcelain tooth and repair paster.
E. the tooth of said porcelain being repaired paster carries out the car porcelain, polishes then or glazing obtains the finished product that tooth is repaired paster.
More than a kind of tooth based on CAD and RP technology is repaired paster to the embodiment of the invention provided manufacture method carried out detailed introduction; For one of ordinary skill in the art; Thought according to the embodiment of the invention; The part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as limitation of the present invention.
