The hook of demoulding clamps and dismoulding system.
Technical background
Invisible orthotic device without bracket is a kind of transparent elastic material activity correction for being related to and making by area of computer aided
Device, it is a series of continuous orthotic devices, achievees the purpose that orthodontic by continuous little scope moving teeth.
Chinese patent application 201410482539.5 discloses a kind of production method of invisible orthotic device without bracket, including：
1, patient oral cavity data are obtained, data establish the threedimensional model in patient oral cavity according to the oral cavity, and threedimensional model includes tooth number
According to gum data；2, scheme is rescued in design, and tooth position to be corrected is adjusted to target corrected position, obtains dentognathic model；In tooth
Cutting line is generated on gnathode, and three-dimensional dentognathic model is shaped to entity dentognathic model with rapid shaping mode, uses vacuum film pressing
Mode by membrane covered on entity dentognathic model；It will be covered with entity dentognathic model the cutting with three-dimensional dentognathic model of diaphragm
Secant is that cutting path is cut, and after the completion of cutting, diaphragm demoulds to form appliance.
In the prior art, it all focuses on how to make dentognathic model or how to cut diaphragm to form appliance, automate
It designs and makes also until diaphragm cutting is completed.It is typically by worker's hand ejection, after demoulding that diaphragm, which demoulds and to form appliance,
Manual grinding deburring obtains appliance product again.
Currently, in demoulding link, since high-molecular diaphragm is adsorbed on the dentognathic model of entity, and the thickness of diaphragm only has
0.5mm ~ 0.75mm so that worker is time-consuming and laborious when being peeled off diaphragm from dentognathic model with finger, and it is frequent because
To exert oneself, excessive or force unevenness causes appliance fracture or the fracture of tooth mould.
Invention content
The purpose of the present invention is to provide a kind of in the demoulding link of invisible orthotic device manufacturing process, and worker is without using hand
Refer to stripping piece, make the power uniform force application of demoulding, protect worker's finger and appliance, improves extractor hood pincers, the demoulding of demoulding efficiency
System and release method.
A kind of extractor hood pincers of invisible orthotic device without bracket, including handle, clamp the cheek and plier；Plier be one pair in hook it is thin
Silk, filament be able to be inserted into the demoulding hole on dentognathic model.
Further, the diameter in the section of filament or length are 0.5mm ~ 1.2mm.
Further, respectively by a stainless steel steel wire bending forming, two stainless steel steel wires are hinged for plier, the pincers cheek and handle
Form the extractor hood pincers.
Further, the section for clamping the cheek is more than the section of plier, and plier is arc-shaped.
Further, rubber sleeve is covered on handle.
A kind of dismoulding system of invisible orthotic device without bracket, including above-mentioned extractor hood clamp and are set to dentognathic model surface
Demoulding hole, demoulding hole is arranged in pairs, is located at another hole of tongue side per a pair of of demoulding hole, a hole and is located at cheek side；Hole is demoulded to clamp with hook
Plier clearance fit；Demoulding hole is located on the gum line of dentognathic model.
Demoulding hole, which is located on gum line, refers to that gum line passes through demoulding hole, that is, demoulds a hole part on gum line,
A part is under gum line.When making invisible orthotic device, needs to cut diaphragm along gum line to remove extra material, cut
After the completion of cutting, the demoulding bore portion on gum line is by the membrane covered of appliance.When the plier of extractor hood pincers is inserted into demoulding hole
When interior, plier can catch on the diaphragm of invisible orthotic device.
The alveolus and gum of human body are in up-small and down-big, and demould hole and be arranged along the surface of dentognathic model, then two demouldings
Hole certainty opposite tilt, i.e., in cross section, two demoulding holes are in eight word arrangements.By the diaphragm of invisible orthotic device from tooth jaw mould
When type demoulds, plier is inserted into demoulding hole and catches on invisible orthotic device（Lip）The diaphragm of cheek side and tongue side clamps extractor hood past
The direction of principle dentognathic model is drawn, until diaphragm is eased out from dentognathic model.Extractor hood is clamped from demoulding hole again and is taken out.
Further, demoulding hole is set to the neck gap location of two teeth.In a pair demoulds hole, hole position is demoulded when one
When the cheek side of the neck gap location between second molar and first molar, another demoulding Kong Ze is located at second molar and first
The tongue of neck gap location between grinding one's teeth in sleep.Two demoulding holes i.e. per a pair of of demoulding hole mutually align.
Further, multipair demoulding hole is equidistantly distributed on dentognathic model.Between herein equidistant refers between demoulding hole
Every tooth digit it is identical.
The present invention is inserted into a pair of of demoulding hole in the demoulding link of invisible orthotic device manufacturing process, by the plier of extractor hood pincers
It is interior, while the appliance diaphragm of both sides is caught on, extractor hood is clamped to the direction far from tooth jaw physical model and draws and diaphragm can be made to take off
From tooth jaw physical model.There is the present invention worker to be not necessarily to use finger stripping piece, the uniform force of appliance diaphragm both sides when demoulding,
Worker's finger can be protected not injured and fracture that appliance occurs by unbalance stress, moreover it is possible to improve demoulding efficiency
The advantages of.
