Technical Field

The invention belongs to the technical field of tooth correction, and particularly relates to the technical field of shell-shaped tooth correction devices, in particular to a combined orthodontic appliance, a correction device set using the orthodontic appliance and a correction system.

Background

Orthodontics mainly correct with strength, and correct the ware and be a device of treatment malocclusion deformity, it can produce the effort, and wherein activity is corrected ware, the function is corrected ware and is fixed to be rescued the three big systems of correcting the technique jointly.

The fixed appliance is an important type in the orthodontic appliance, the fixed appliance is fixed on teeth by adhesion or ligation, and the fixed appliance has the characteristics of good retention, sufficient anchorage, suitability for applying various types of correction force, contribution to the movement of most teeth, capability of effectively controlling the movement direction of the teeth and the like, so that the fixed appliance is widely applied to the treatment of orthodontic. There are many types of fixed appliances, of which the lip, lingual appliance, and double appliance are older fixed appliances. The multi-ring appliance has become a fixed appliance widely used in clinic, such as an edgewise appliance, a thin-wire appliance, and the like. The force application part of the fixed orthodontic device is an orthodontic arch wire and mostly consists of stainless steel wires and alloy steel wires.

The movable appliance can be freely taken off and worn by a patient or a doctor, and the appliance is intact when being taken off; it plays a role in correction by means of retention of the snap ring and adsorption of mucous membrane. The doctor can increase or decrease the accessories which can generate the correcting force on the correcting device as required so as to achieve the purpose of correcting the malocclusion.

The fixed appliance and the movable appliance have advantages and disadvantages, and the advantages of the fixed appliance include: 1) the retention is good, and the anchorage is sufficient; 2) can move a plurality of teeth; the whole movement, the torque, the torsion and other movements are easy; 3) The moving direction of the orthodontic treatment tooth can be controlled; 4) can correct more complicated malocclusion deformity; 5) the volume is small and the device is comfortable; 6) the pronunciation and the spoken language training are not influenced; 7) the time interval between the clinical re-diagnosis and the stress application is long; 8) the patient can not take off the appliance by himself and does not wear the appliance, so the appliance can be continuously exerted. And the disadvantages of fixed appliances include: 1) when the fixed appliance is worn, the oral health care needs to be particularly paid attention to, if the fixed appliance cannot be particularly paid attention to, caries and gingivitis are easy to cause; 2) the fixed correction technology is relatively complex, and the clinical chair-side operation time is long, so the fixed correction technology can only be used by experienced doctors; 3) if the force is too large, the patient can not take the medicine out of the bag by himself, and the damage of periodontal tissues is easy to cause sometimes, and adverse results are generated. The advantages of the removable appliance include: 1) the patient can take off and wear the appliance by himself, which is convenient for washing and brushing and can keep the appliance clean and the oral hygiene; 2) avoiding damage to periodontal tissues of the tooth body; when the force is too large and the pain is relieved, the patient can detach the appliance by himself, and the correcting force can be eliminated due to the deviation of the correcting appliance; 3) the appearance is not influenced; if the user needs to do external traffic, perform and other occasions, the user can wear the clothes at night; 4) can correct common malocclusion deformity. Disadvantages of removable appliances include: 1) insufficient anchorage; 2) the acting force is single, the capability of controlling the tooth movement is not as good as that of the movable appliance, the tooth movement mode is mostly inclined movement, and the integral movement is difficult; 3) influence pronunciation; because of the base, tongue mobility is limited; 4) the feeling of foreign body is felt; 5) the remaining gap is difficult to handle. In summary, the fixed appliance and the movable appliance have advantages and disadvantages, and if the advantages of the fixed appliance and the movable appliance are taken into consideration, the fixed appliance and the movable appliance can avoid the disadvantages of the fixed appliance and the movable appliance, have better correction effect on the treatment of special cases, and have important significance. In recent years, the invisible tooth appliance in the movable appliances is more and more accepted by orthodontic patients due to the convenience of taking and wearing.

However, the invisible orthodontic technology still has defects and short plates, and the invisible orthodontic appliance has limited functions when the following clinical problems are corrected, which mainly shows that: 1. severe malocclusion of individual or groups of teeth, such as twisting, tilting, labyrinthine, vertically low, etc.; 2. leveling the Spee curve and establishing a posterior occlusal abutment; 3. The tooth extraction case comprises anterior adduction, retroversion control and tooth extraction residual gap closing. Therefore, the technology of fixing and correcting the invisible teeth is combined, the technical problems are solved, and the method has important significance.
