Description
Technical field
The present invention relates to mouth cavity orthodontics to rescue technical field, and in particular to be a kind of novel orthodontic method.
Background technique
Deformity teeth is main one kind in mouth disease, there is very high illness rate, and mentioning with human living standard
Height, illness rate are also continuously increased.Traditional invisalign method mostly uses the raw material production of same thickness or unified material to rectify
Device is controlled, the disadvantage is that cannot be controlled for the special movement direction of certain tooth or a few teeth in different treatment stages
System.Or the expansion in therapeutic process is bent, leveling arch, release lockEqual therapeutic modalities can not achieve desired effect.To make
The progress come into line in therapeutic process to the overall movement of tooth not can be carried out control, if wherein certain tooth or part can not be ensured
The expection treatment results of several teeth；So wholistic therapy process just will appear deviation, entirely rescues process and just needs repeatedly again
Start therapeutic process, therapeutic process is made to extend or can not carry out invisalign.Treatment time and energy are increased for patient.
Invisible orthotic device product is because the sclerotin condition of each patient is different, and patient needs patient to have very high fitness, often
Its wearing 22 hours or more time, when using product, few patients can be good at controlling wear time.It will appear more
Therapeutic effect caused by cumulative errors is poor.
In comparison, this novel method for the treatment of invisible orthotic device can then overcome the problems, such as those described above, novel
The technology of rescuing can carry out staged planning for the therapeutic scheme of patient to be rescued, for each treatment stage therapeutic purpose not
Together, a collection of appliance is produced using the diaphragm of unlike material performance, for rescuing patient's wearing, the treatment for the treatment of stage each in this way
Target can be realized targetedly, so that each design treatment results during making wholistic therapy can guarantee.
Summary of the invention
In view of the above shortcomings, the purpose of the present invention is to provide a kind of novel orthodontic methods, guarantee entire
The expection treatment results of invisible orthotic device process, shorten the treatment cycle of current invisalign, are more advantageous to and rescue patient's
Rescue the propulsion of process.
Technical solution of the present invention is summarized as follows:
A kind of novel orthodontic method, wherein include:
1) patient oral cavity data are obtained: directly scanning acquisition with scanning tools；Or by the way that gypsum is perfused after buccal impression
Then model is obtained with laser scanner scans plaster cast；
2) it determines the parameter of oral cavity threedimensional model: the patient oral cavity data that step 1) obtains is passed through into certain processing side
Method, the restoring force of material needed for determining each invisible braces according to the thermodynamical model of less material and offer, according to
The restoring force that tooth amount of movement and each invisible braces provide determines the treatment cycle of each invisible braces, thus
To the dental arch model of orthodontic treatment stage by stage；Wherein, whether the parameter of the oral cavity threedimensional model includes whether to expand bow, move
It moves, whether release underbite of anterior teeth；
3) it constructs the threedimensional model of invisible orthotic device: determining that meter is rescued in the parameter formulation of oral cavity threedimensional model according to step 2)
It draws, for the moving distance of each tooth, moving direction, mobile form, design is each to rescue adjusting stage corresponding expection
Target digitization tooth model；
4) it makes invisible orthotic device: each target digitlization tooth model of step 2) is pre-processed,
Patient information and therapeutic progresses information are edited on model, are reached and are able to carry out the molding production requirement of 3D printing, utilize SIA laser
Molding 3D printing molding equipment prints a series of entity tooth model of target digitlization tooth models, by invisalign
The diaphragm material of device is heated by thermoplastic film laminator, and will suppress the invisalign to match on each entity tooth model
Device；
5) treat: patient's wear contact appliance treats tooth, and each stage, expected therapeutic purpose was different, used hidden
Shape appliance is different, and the diaphragm material of each invisible orthotic device is different, measures the invisible orthotic device pair for currently rescuing the stage
The Orthodontic force of target tooth judges whether to replace the invisible orthotic device for currently rescuing the stage according to the Orthodontic force；It determines
After replacing the invisible orthotic device for currently rescuing the stage, next width invisible orthotic device is worn according to the plan rescued until to institute
The stealthy correction for stating target tooth is completed.
Preferably, the novel orthodontic method, wherein the entity tooth model of the step 4) is suppressed stealthy
Before appliance, it is also necessary to be cleaned, the surface treatment step of photocuring.
