embodiment 3 compliance test result
Any one scanning system described in embodiment 1 or 2 is adopted by 10 odontologist, No. 10 number stamp process operation is respectively carried out to same object, in contrast, these 10 odontologist adopt again number stamp scanning system in mouth of the prior art respectively to carry out No. 10 number stamp process operation to object respectively.Comparing result is as follows:
Process total time: the acquisition process of number stamp generally can comprise: standby body cleaning, preparation process, multi-angle scans, and checks scan-data (face graphic data is analyzed, and various visual angles are observed), when scanning, checking scan-data, there is more mutual (as: face shape integrity, face shape reasonability, various visual angles observation, patient is mutual, data analysis etc.); Occlusal surface also will perform identical step.Data viewing module provided by the invention and interactive module, can conveniently at multiple view angle switch, and the data results after switching is directly showing over the display.And put down scanheads without doctor, carry out mouse action, shift position, insertion probe etc., thus greatly can shorten the time obtaining and analyze needed for number stamp, the multiple scanning number of times obtained needed for desirable die also obviously reduces.Number stamp scanning system in mouth of the prior art is adopted to carry out number stamp acquisition and analysis; required multiple scanning number of times average out to 6 ~ 8 times; required total time is 732 ± 101 seconds; and adopt scanning system of the present invention to carry out number stamp acquisition and analysis; required multiple scanning number of times average out to 1 ~ 3 time; required total time is 146 ± 57 seconds, and the difference between two kinds of scanning systems has statistical significance.
Accuracy: adopt number stamp scanning system in mouth of the prior art to carry out the precision (size difference between real income die and desirable die) of number stamp process gained die usually at 25 microns.And adopt scanning system of the present invention to carry out number stamp process, the precision of gained die can control less than 15 microns, and this difference all has significant difference, the accuracy adopting scanning system of the present invention effectively can improve number stamp process is described.This to be adjusted accurately probe by the content of the display display on probe due to user and control thus can easier gated sweep probe, improves and obtain chance of success, reduce pendulous frequency, improve certainty of measurement.
Repeatability: experiment display, just adopt scanning system of the present invention to carry out size difference between the number stamp that repeatedly number stamp process obtains at 10 ± 6 microns to same object, its repeatability is significantly better than adopting existing scanning system to carry out number stamp process (corresponding size difference is 36 ± 48 microns).
Fig. 4 is the width scanning result figure adopting scanning system of the present invention to obtain on described probe display, and user is easy to see scanning result by the display on probe, and can control the explicit content of display by human-computer interaction interface.Displaying contents can the scanning result of intuitive display, also can display data analysis result.
The foregoing is only the preferred embodiments of the present invention, is only illustrative for the purpose of the present invention, and nonrestrictive; Those of ordinary skill in the art understand, and can carry out many changes in the spirit and scope that the claims in the present invention limit to it, amendment, and even equivalence is changed, but all will fall into protection scope of the present invention.
