Anatomic model tooth arranging method for personalized tongue side correction

Abstract

The invention relates to an anatomic model tooth arranging method for personalized tongue side correction. The anatomic model tooth arranging method for the personalized tongue side correction comprises the following steps of: 1) making a correcting plan; 2) manufacturing an impression and transferring to an occlusal frame: manufacturing a plaster model and recording and transferring an occlusal position to the anatomic occlusal frame through a face arch; 3) model marking and trimming; 4) drawing a standard arch; 5) according to the standard arch, arranging teeth by using an upper tooth arch; and 6) arranging teeth by using a lower tooth arch, wherein in the step 2), a relationship between an eye and ear plane and an occlusal plane is transferred to the anatomic occlusal frame through the anatomic face arch, so that the anatomical positions of the teeth in a mouth are really represented; and in the step 5) and the step 6), adducent amounts and torque change values of maxillary anterior teeth are transferred to an angular relationship between a tangent line of a dentilabial surface and the occlusal plane by using a self-made angle ruler, and the positions of mandicular anterior teeth are determined according to the positions of the maxillary anterior teeth and an occlusal relationship, so that the teeth on one side are in standard arrangement and the teeth on the other side are malocclusive.

Description

technical field [0001] The invention relates to a method for making an in vitro model used in the field of orthodontics, in particular to an anatomical model tooth arrangement method for personalized lingual correction. Background technique [0002] Correction of dentognathic deformities is a complex process, and the movement of teeth in the jaw is a three-dimensional movement. For the design of the orthodontic treatment plan, in addition to determining the gap analysis in the dental arch, the influence of factors such as Spee curvature, incisor inclination, ratio of upper and lower teeth volume, and bone-surface protrusion should also be considered. The model tooth arrangement test means that before orthodontic treatment, considering the above factors, by simulating the arrangement of the teeth in the ideal position and establishing a normal occlusal relationship, it is of great value in the manufacture of individualized appliances and indirect bonding. The model set-up te...

Problems solved by technology

Therefore, the defect of the existing technology is that the overall shape of the teeth in the oral cavity is ignored, that is, the tooth arrangement model is considered separately from the occlusal plane, which leads to the fact that the tooth arrangement model cannot truly reflect the relationship between the teeth and the occlusal plane, jawbone, and soft tissue profiles. , cannot accurately reproduce the original position and target position of the teeth in the oral cavity
