Demoulding hook clamp and demoulding system of bracketless invisible appliance

Abstract

The invention discloses a demoulding hook clamp of a bracketless invisible appliance. The demoulding hook clamp comprises a handle, a clamp cheek and a clamp mouth, wherein the clamp mouth consists of a pair of inward-hooking thin filaments which can be exactly inserted into demoulding holes in a dental model. A demoulding system of the bracketless invisible appliance comprises the demoulding hook clamp and demoulding holes formed in the surface of the dental model; the demoulding holes are formed in pairs; in each pair of demoulding holes, one hole is positioned on the tongue side while the other one is positioned on the cheek side; the demoulding holes are in clearance fit with the clamp mouth of the hook clamp; and the demoulding holes are positioned on the gingiva line of the dental model. The advantages of the invention are as follows: in a demoulding link of the production process of the invisible appliance, a worker does not need to strip the membrane with fingers, the demoulding force is uniform, the worker fingers and the appliance are protected, and the demoulding efficiency is improved.

Description

technical field [0001] The invention relates to a hook forceps and a demoulding system for demolding the diaphragm of the invisible aligner from the dental jaw model when making the invisible aligner without brackets. technical background [0002] Bracketless invisible aligner is a kind of transparent elastic material movable orthodontic device designed and manufactured by computer aid. It is a series of continuous orthodontic devices, and the purpose of orthodontics is achieved by continuously moving teeth in a small range. [0003] Chinese patent application 201410482539.5 discloses a manufacturing method of a bracketless invisible aligner, including: 1. Obtaining the oral data of the patient, and establishing a three-dimensional model of the patient's oral cavity based on the oral data. The three-dimensional model includes tooth data and gingiva data; 2. Design the orthodontic plan, adjust the position of the teeth to be corrected to the target orthodontic position, and o...

Problems solved by technology

[0005] At present, in the demoulding process, since the polymer membrane is adsorbed on the solid jaw model, and the thickness of the membrane is only 0.5mm~0.75mm, it is time-consuming for workers to peel off the membrane from the jaw model with fingers It is strenuous and often breaks the appliance or mold due to excessive force or uneven application of force
