Embodiment Construction

[0032] The present invention is described below in conjunction with accompanying drawing:

[0033] At present, the order of tooth arrangement is mainly divided into two categories: mandibular tooth arrangement method to locate the position of lower incisors by referring to X-ray cephalometric measurement, and maxillary tooth arrangement method to locate upper incisors by referring to the original dental arch shape and occlusal curve. Since the target position of the lower incisors is easier to determine than the upper teeth, the lower anterior teeth are more likely to exceed the bone boundary than the upper jaw, and studies have shown that the lower jaw teeth arrangement method is more reasonable and beneficial to the health of the stomatognathic system. The tooth arrangement method of the present invention, namely The digital teeth arrangement method based on tooth root information adopts the maxillary tooth arrangement method. Proceed as follows:

Abstract

The invention relates to a digital tooth arrangement method used in the field of orthodontics. The digital tooth arrangement method is characterized in that the positions of tooth roots in a tooth arrangement process are displayed by using the digital technology; the tooth arrangement result is enabled to be within the physiological limitation and to be more accurate and reasonable. The method comprises the steps: 1, establishing an orthodontic virtual dentognathic model comprising tooth root information; 2, determining points and parameterizing all teeth; 3, defining a global coordinate system; 4, arranging mandibular teeth: 1) positioning lower incisors, 2) constructing a bracket plane, 3) constructing a dental arch curve and arranging teeth, 4) constructing a tooth root plane and a root face curve, and 5) adjusting the positions of tooth roots; 5, arranging maxillary teeth: 1) positioning upper incisors, 2) adjusting maxillary bracket points and constructing a bracket plane, 3) constructing a maxillary dental arch curve and arranging teeth, and 4) adjusting the positions of tooth roots; 6) fine tuning a tooth arrangement result on the basis of collision detection.

Description

technical field [0001] The invention relates to a digital tooth arranging method used in the field of orthodontics, which is characterized by a method for displaying the tooth root position during the tooth arranging process through digital technology. Background technique [0002] At present, whether it is artificial tooth arrangement or computerized virtual tooth arrangement that has been commercialized, only the arrangement of the crown and occlusal contact are considered, and there is a lack of reference to root information, alveolar bone limits, and the relationship between the root and the craniofacial bone. its biological plausibility. Clinically, whether the tooth roots are aligned in parallel is an important criterion for evaluating the therapeutic effect. The vast majority of orthodontists observe the position of the root through the curved X-ray film during and after the treatment, but a large number of studies have confirmed that the curved X-ray film cannot acc...
