Optimization method of invisible orthodontic appliance

Abstract

The invention discloses an optimization method of an invisible dental appliance. The optimization scheme of the invisible dental appliance is reasonable; modelling is indirectly performed through simulating the tooth moving process by finite element software, so that a continuous invisible appliance model which conforms to the actual shape is established, and the continuous invisible appliance model is accurately assembled in a dental model; the integrated effect of an invisible correcting technology to dentition can be researched, and the optimization scheme is applied based on set constraintconditions and a nonlinear finite element analysis method, so that the simulation authenticity of the invisible appliance model is guaranteed; the stressing situation of periodontium and the invisible appliance is analyzed and optimized, the correcting force exerting region is controlled, the stress distribution of anchorage teeth is reduced, counter-acting force is dispersed through balancing force acting on the appliance, the mechanical anchorage consumption is educed, optimal correcting force is exerted, the reconstruction of the periodontium is effectively promoted, ideal moving of the teeth is produced, and the best correcting effect is achieved.

Description

technical field [0001] The invention relates to an optimization method, in particular to an optimization method of an invisible dental appliance, and belongs to the technical field of orthodontic methods. Background technique [0002] The main method of correcting malocclusion is to apply appropriate corrective force to the misplaced teeth, so that they can move to the correct position and rebuild a coordinated, healthy and stable jaw relationship. Therefore, the force movement of teeth is the basic step of orthodontic treatment. Compared with the traditional fixed orthodontic technology, the invisible orthodontic technology without brackets no longer relies on the deformation of the arch wire, spring or rubber ring to generate the orthodontic force, but continuously applies the orthodontic force generated by the elastic deformation of the appliance material to the teeth to be moved. So as to achieve the purpose of correction. [0003] When the orthodontic force is applied ...

AI Technical Summary

Problems solved by technology

[0004] 1. The orthodontic force generated by elastic deformation may not only act on the orthodontic teeth, but may also act on the anchorage teeth if it is not reasonably controlled, resulting in the loss of the anchorage part and failing to achieve the orthodontic effect;

[0005] 2. The size, direction and action position of the correction force directly affect the control of anchorage, thereby affecting the correction effect;

[0006] 3. The force acting on the aligner must be balanced, and the improper area of ​​the balance force will also lead to wrong correction
