Description of the invention: [Technical field to which the invention pertains] In particular, a method of simulating a crown is a method for simulating a three-dimensional denture model. [Prior Art] Dental implants (dental imp丨ant) are single or multiple teeth lost by dentures and human diseases or trauma, and the false depth and the occlusal plane are established. The waiter considers the different bitings of the six women (the goal is that all teeth are balanced r:rrrch-e when they are in the middle of the occlusal contact), and the direction of the force of the bite can be in the force zone of the rhyme. The factors are inseparable from the production and the denture of the denture: the shape and the angle of the denture (denta丨cuspid) are inseparable. In the current practice, the method of arranging the dentures by hand is difficult to symmetrical or balance the function. Traditionally, dentists have used occluded instruments such as Set_up templates to provide accurate experience with the dentures. Curve of spee) is connected to the scalp of the caries area (curve Of Wj|S0ri). ^ After finding the best position of the teeth, the dentist must know the width and height of the tibia according to the two-dimensional image of the panoramic X-ray, and empirically test the artificial roots and the sinus and inferior alveolar nerves and blood vessels. These anatomical constraints on the relative position of the implants to each other create difficulties in determining the location of the implant, and this method of relying on two-dimensional images to detect space also reduces the safety of the operation in 200920322. The assisted dental implants have been developed to assist the doctor in preoperative =, and in terms of providing images, they can be used as two-dimensional and three-dimensional image software. For example, DeI & like the 丨Gl software that assists the upper and lower hairs, that is, using the plane shadow image to judge the position and the side of the plant that must be visually intercepted by the doctor during surgery: r:s: position of the inner section, manual adjustment of the implant The tooth orientation, the household tongue, and the ant4 dental implant software provide distance measurement on the two-dimensional image built in the software to generate the surgical drilling template. In addition, NobelGuideTM software: simulation of limb position and depth i, the process of making a surgical mold is shortened into so-called "injustQnevisit". The tooth is complicated, however, 'the above software can not clearly provide the dentist with the possible implantation surface implant point.' It is still necessary for the doctor to judge the implant surface and t straight:: determine the implant position, angle I, depth; The software automatically establishes the reference orientation available for implants without... At present, the dentist will arrange two perfect compensatory lines with the set of teeth (set, up expiates) before implanting the teeth, so that the teeth are longitudinally drawn from the 'heart, ridge vertical' to achieve the occlusal balance and obtain the teeth of the patient. Biting the human face as the basis for dental implant surgery' However, the current curved tooth plate has different specifications of the crown angle. It has different designs according to the theory and the race, but it is still not a personalized product. Most of the surface sprocket plates on the market are 杲 杲 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' Especially for patients with single missing teeth or multiple missing teeth, since most of them are healthy teeth, the normalized curved tooth plate is not suitable for replacing the existing 200920322 occlusal surface. It is necessary to follow the patient's original A bite is a preferred practice. The purpose of the invention is to select the denture crown. The main purpose of the present invention is to provide a dental biting method to simulate the denture of the patient's missing tooth and its three-dimensional; pre- and post-operative crown; ^ T 4, k for the reference position of the doctor U, to mention the quality of implant surgery. The main techniques used by Nuda for the above purposes include the following: The teeth of the occlusal teeth are turned over to the patient's dental molds, and the markers are added to the upper/lower jaws of the dental molds; the dental molds with the labeled objects are scanned by computer to obtain: net! :: and the upper/lower marker in the conversion moment of the computerized tomographic image. The dental mesh data is cut into mxn complex grids according to the selected cutting area and projection range; The occlusion action to obtain the transformation matrix of the upper/lower tracking board and its relative relationship matrix with the marker; the transformation matrix of the upper/lower tracking board and the relative relationship matrix, and calculate the relative relationship of the lower sputum marker to the upper sputum mark, or The relative relationship between the sputum marks on the sputum mark; the upper/lower impression of the calculus; the conversion matrix of the δ hexon in the computed tomography image, the relative relationship with the sputum mark on the upper sac mark, or the squat mark The relative relationship of the upper rhyme marks to obtain the dynamic position of the lower 颚 grid point on the upper ridge, or the dynamic position of the lower 颚 grid point on the upper ;; taking the projection position of the dynamic position, calculating the depth amount, and then substituting the square; It corresponds to the grid position function; 200920322 repeats the third to sixth steps, - τ. ^ 'to complete the mesh number of all cutting regions, until the preset Summer Cover # - number reaches less; find the best function of each grid point; and a value 'which represents the most deeply cut made in the grid most Pan then each grid occlusal surfaces of teeth. The cut point is meshed and calculated, and the other method of the present invention - the denture model of the present invention is described in the step V after the step of the brain to scan the height of the brain, and the standard denture is connected to the mapping model to establish the Build 2' or use the mirror technique to obtain the tooth mesh model of the heart, and since the tooth mesh model contains the shape, the lingual side and the front side and the front and back sides of the tooth will be ω The parental surface performs the difference and reads the denture. The above-mentioned simulated tooth crown difference is established - the yuan is erected less than 2 times). The chewing movement is up to 4 times by the patient (to reach the establishment of the teaching and payment), and during this period The movement is green and the movement of the rails, the cutting movement, so if the above stomach knives and work „E „, Bessie is an example', it must be 兮+曾* loss page ideal crown surface, this time τ shoulder. Ten calculations from the ^ τ P to the lower jaw model as "knife and,, the mouth and the trajectory as a cutting path knife ... and can be carved out of the occlusal surface as the upper missing: =, and in space The middle carving refers to the tooth mesh model, and establishes the type 4 that the doctor can simulate through the invention. The patient is actually engaged in the occlusion process, the gingival W image, and the degree is provided. The detailed record of the second is by the bite: the deep assisted dentist on the face: the height of the teeth, the shape of the crown, and the basis for the angle of the 阜 and (= 200920322 cuspid).
