Embodiment 1

[0025] A motor-driven dental arch curve generator, which consists of: U-shaped spring plate 1, the U-shaped spring plate 1 with a set of hinge points is connected to the frame, and the U-shaped spring plate is respectively connected to the frame through the hinge points. A group of two-dimensional motion platforms 2 are connected.

[0026] The motor-driven dental arch curve generator, the two-dimensional platform is composed of two one-dimensional motion platforms, the two one-dimensional motion platforms are vertical, and the one-dimensional motion platform has a stepping motor 4 , the stepper motor 4 is connected to the screw rod 6 through the coupling 5, the screw rod 6 is connected to the slide body I 3, and the hinge support body 7 is fixedly connected to the slide body I to drive the teeth The cylindrical pin deformed by the bow curve generator is inserted into the pin hole 10 of the hinge support body, and the sliding table body I 3 is respectively connected with tw...

Embodiment 2

[0028] 1. Mechanical structure

[0029] There are 5 control points on the U-shaped spring plate, the position of the middle point is fixed, and the remaining 4 points are symmetrically arranged on both sides of the middle point, which are respectively driven by 4 two-dimensional motion platforms to achieve any position within a certain range in the horizontal plane . By reasonably controlling and driving the 4 points on the U-shaped spring plate, the dental arch curve of the complete denture for a certain patient can be obtained.

Abstract

The invention relates to a dental arch curve generator driven by a motor. In an automatic tooth arrangement machine, if a dental arch curve or a translational curve formed by the proportional expansion of the dental arch curve is constructed in advance, the automatic tooth arrangement can be more convenient; and the construction of a dental arch curve generator capable of generating the dental arch curve is quite necessary. The dental arch curve generator comprises a U-shaped spring plate (1), wherein the U-shaped spring plate (1) with a group of hinged points (2) is connected with a frame and respectively connected with a group of two-dimensional motion platforms by the hinged points. The invention is applied to the generation of a dental arch curve and complete denture arrangement operation in tooth orthodontics.

Description

technical field [0001] The invention relates to a motor-driven dental arch curve generator capable of realizing automation, mechanization and computerization. Background technique [0002] Jaw arch curve or dental arch curve: When all the natural dentition in the human oral cavity is lost, an edentulous jaw is formed. When the dentition is lost, the patient's maxillofacial morphology changes, and the pronunciation and masticatory functions are also seriously affected. In order to restore the maxillofacial morphology and physiological functions of edentulous patients and protect the health of the maxillofacial tissue and mandibular joints, it is necessary to repair the complete dentures for the patients in a timely manner. [0003] The geometry of the actual jaw and dental arch curves is very irregular, and it is difficult to accurately describe them with mathematical expressions. In order to simplify the description of the jaw arch and dental arch, and considering that the...
