Description
Technical field
The present invention relates to orthodontic fields.
Background technology
The method of traditional abnormal tooth correction is that patient is allowed to wear so-called " tooth set ".Tooth set be by bracket, arch wire, tied rope and
The device of O-ring composition.During traditional orthodontic, before tooth set is fixed on patient teeth, weak acid is used
Handle dental surface, it is therefore an objective to the adhesive property for improving dental surface, so that bracket and garter spring are bonded in dental surface.Acidification
Afterwards, bracket and garter spring are fixed on by suitable binding material on the tooth of patient by doctor.Pacify again after binder fixation
Fill force application apparatus --- arch wire.
Arch wire is the main force application apparatus of traditional tooth set.Arch wire high resilience is fixed on by the slot on bracket on bracket.
Arch wire connects many brackets, and constantly to bracket applied force so that tooth moves.It reverses steel wire or plastics O-ring is logical
It is commonly used for fixation of the enhancing arch wire on bracket.In orthodontic technology, arch wire is fixed on bracket and is frequently referred to be " binding ", gold
Belong to silk and be known as " tied rope ", plastics O-ring is known as " plastic part ".
After arch wire is in place, patient adjusts tooth set there is still a need for the further consultation of orthodontist there is periodically arrived, such as replacement has not
With the arch wire of force performance, existing tied rope is replaced or tightened.In general, carrying out a further consultation per 3-6 weeks.It is this for patient
The rectifying effect of traditional correction is fine, but there are problems that：Doctor fixes bracket according to visual sense feeling completely, it is difficult to ensure that
The position of bracket is ideal as it is expected；Bracket is exposed to outside, influences the beauty of patient；The contact surface of tooth set and tooth
Because being difficult to clean for a long time, lack effective health measure, is easy to cause saprodontia, oral cavity or periodontal infection；Multiple further consultation is more
Change arch wire or tied rope, not only increase the expense of patient, also allow the patient feels to discomfort.
Therefore, people continuously attempt to replace a kind of antidote of more science.Such as Kuroda (1996) exists
Am.J.Orthodontics110：Described in 365-369 it is a kind of with laser scanning tooth jaw gypsum to generate tooth jaw digital picture

The movement that final position is set, design and make it is a series of have different geometries, realize by tooth from original position to final position
The system rearranged, user can pluck the instrument unloaded to treatment end since treatment using a whole set of transparent stealth.This
A little instruments are by number or the sequence of label uses.But if desired location is not achieved in the movement of certain teeth, tooth can be caused real
The difference of border position and desired location further increases, in this way, asymmetric power is will produce relative to other teeth, to increase
The pain and discomfort of patient.In addition, stealthy appliance is prepared with high molecule plastic material, this kind of material has enough
Elasticity, but it is weaker to rescue strength, and usually become loose due to aging and deformation during patient reuses, make
Corrective force loses.Therefore they, which are only only suitable for the state of an illness, slightly, only needs faint strength of rescuing to can be achieved with tooth rearrangement
Case.Stealth plastics rectifier is mainly used for beauty therapeutic at present, can not but be widely used in orthodontic treatment.And stealthy acrylic resin tooth
Set, since facing is using made of high molecule plastic material, hardness is poor, if the distance of facing moving teeth is excessive, no
But good rectifying effect cannot be played, and the patient feels can be made very uncomfortable.Therefore, in correction times, per pair facing
It can only be designed to that tooth is made to move in smaller distance, entirely rescue system and a large amount of single width facings is just needed to be rescued,
The cost entirely treated just improves, and very big financial burden is constituted to patient.
Removable appliance, also referred to as removable appliance, which are a kind of patients, can freely pluck the apparatus for correcting worn, by fixing device,
Force application apparatus and attachment device three parts composition.Common fixing device has snap ring and embrasure hook；Common force application apparatus is main
It is spring, such as hyperbolic tongue, hyperbolic lip bow, expansion bow spring and guide plate；Attachment device be typically plastic base constitute, some then by
Palate bar and hyoid arch composition.Common removable appliance is shown in Fig. 1-4.These rectifiers can usually cause patient's dysphonia, there is foreign matter
Sense, patient are often difficult to adhere to wearing.But if patient is unable to partner treatment, cannot adhere to wearing use, therapeutic effect just no
To guarantee, eventually leads to tooth rebound/recurrence under orthodontic treatment and greatly reduce to original position and move device using this
The correction curative effect of tool.
Therefore, it is necessary to a kind of not only beauties, but also do not interfere with patient comfort, and can reach quick treatment, shorten treatment
The course for the treatment of reduces facing cost of manufacture, reduces the orthodontic system of patient economy burden.
