Embodiment Construction

[0072] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0073] A kind of numerical control laser automatic tooth body preparation method of the present invention of the present invention, is made up of the following steps:

[0074] 1) Use an intraoral 3D scanner to obtain the 3D surface scanning data of the crown of the target tooth, use a cone beam CT machine in the mouth and maxillofacial region to obtain the 3D data of the crown of the target tooth, and store the above two sets of data separately for subsequent reading operations ;

[0075] 2) Use the tooth preparation CAD software to register the above two sets of data, and unify them in the same coordinate system, extract the edge of the preparation on the computer screen, define the design parameters of the tooth preparation, and segment the enamel, dentin and pulp Cavity, complete the virtual modeling of the tooth preparation, and f...

Abstract

The invention relates to a numerical control laser automatic tooth preparation method and equipment thereof. The equipment contains an intraoral spatial digitizer, a dental laser, a numerical control laser tooth preparation control system intraoral working end, an oromaxillo-facial region cone-beam CT machine, a computer, a tooth fixator and a negative pressure aspirator. The computer is respectively connected with the intraoral spatial digitizer, the dental laser, the oromaxillo-facial region cone-beam CT machine and the negative pressure aspirator. The dental laser is connected with the numerical control laser tooth preparation control system intraoral working end which is connected with the tooth fixator. The equipment can replace part of manual operation of a doctor. A traditional mechanical grinding apparatus is replaced with laser. Clinical therapy operative level of grass-roots doctors can be effectively raised within a short period of time, and diagnosis and treatment efficiency and quality can be improved.

Description

technical field [0001] The invention relates to a tooth body preparation method, in particular to a numerically controlled laser automated tooth body preparation method, and also relates to a numerically controlled laser automated tooth body preparation equipment. Background technique [0002] 1. Manual tooth preparation techniques currently used clinically at home and abroad. [0003] The traditional manual tooth preparation mode is difficult to meet the standard requirements in textbooks and clinical practice specifications. The level of manual tooth preparation in my country is generally low (according to the statistics of relevant experts, the pass rate accounts for about 40%). In my country, the number of high-level dentists is relatively scarce. At the same time, it often takes many years to train a high-level clinician. The above factors together lead to "to see the teeth is expensive, but difficult to see the teeth". In addition, therefore, there is an urgent nee...
