Design method, manufacturing method and system of pre-activated expansion device and pre-activated expansion device

Abstract

The invention provides a pre-activated arch expander design method, manufacturing method and system and a pre-activated arch expander.The design method comprises the following steps that target arch expansion parameters are determined according to an initial dental jaw digital model in an initial dental arch form, and the target arch expansion parameters comprise the target arch expansion amount and the target arch expansion force; determining a target dental digital model in a target dental arch form according to the initial dental digital model and the target arch expansion parameters; and designing a pre-activated arch expander digital model based on the target arch expanding parameters and the target dental jaw digital model. According to the technical scheme provided by the invention, the pre-activated expansion device can be optimally designed and manufactured according to the design target, and the expansion effect on the tooth jaw can be more accurately realized.

Description

technical field [0001] The present application relates to the technical field of orthodontics, and in particular, to a design method, manufacturing method, and system of a pre-activation expander, and a pre-activation expander. Background technique [0002] Arch expanders are commonly used appliances in the field of orthodontics, which can be used to correct narrow dental arches, crowded teeth, and coordinate the width of the upper and lower dental arches. [0003] The expander is generally composed of a retaining part for fixing the appliance on the tooth and an expanding part for expanding the arch. The elastic restoring force generated by the expanding part after the force is deformed acts on the tooth and is transmitted to the back of the alveolar bone. , which can cause the width of the upper and lower dental arches and the alveolar arch to increase, so as to achieve the effect of expanding the arch. [0004] When the existing arch expander is manufactured, it is gener...

Problems solved by technology

When doctors use the expander clinically, they need to adjust and activate the expander parts by themselves. This operation method greatly depends on the doctor's experience and clinical operation techniques. After activation, the actual correction force generated by the expander and the realizable The amount of arch expansion cannot be accurately estimated, and it is likely to be quite different from the expected treatment plan. Therefore, it is necessary to continuously monitor the curative effect and adjust repeatedly during the entire arch expansion process. Such operations are less predictable and difficult for beginners to master

In addition, for children who need to expand the arch, repeated disassembly and assembly of the appliance in the mouth can easily cause them pain and discomfort, resulting in poor fit
