What Are the Different Types of Removable Orthodontic Appliances?

An appliance is an orthodontic appliance that treats malformations. It can produce force, or the function of the perioral muscle function of the masticatory muscles can change the deformed frontal bones and dislocated teeth by the periodontal support tissues through the appliance, which is conducive to the normal growth and development of the dental maxillofacial surface.

Corrector

Corrector (appliance) is a device for treating malformations

Orthotics are usually a kind of stainless elastic metal wire or plastic products, or a combination of mechanical devices, which are actually worn in the mouth or maxillofacial region. In order to make it acceptable to the patient, and does not hinder or lessen normal chewing, pronunciation and other functions, as well as beauty, comfort and durability, it must have the following properties:

1) The braces should have no damage to the soft tissues of the oral cavity and the maxillofacial face, do not react chemically with saliva, meet physiological requirements, and do not affect the normal growth, development and function of maxillofacial teeth.

2) The size of the corrector is as small as possible, comfortable to wear, and the exposed part is as small as possible, which has a small impact on aesthetics.

3) Easy to scrub, easy to clean without affecting

Various orthodontics can move teeth, but the key is to choose the appropriate type. Because the basic structure, technical requirements and search materials of each orthodontist are different, they need to be classified.

Classification according to the purpose of the corrector

1) Correctiveness: Active (orthodontic) maxillofacial deformity is corrected by the legal person, and the force can be mechanical or peroral muscle function.

2) Preventive: the purpose is to prevent possible mistakes (addition of teeth), such as gaps

Orthosis

(1) Advantages: 1 The patient can remove and wear it by himself, which is convenient for scrubbing and can maintain the hygiene of the appliance and the oral cavity. 2 Avoid damage to the periodontal tissue of the tooth. When the force is too great, the patient can remove it by himself, and the correction force can be offset by the dislocation of the appliance. 3 Does not affect aesthetics. For diplomatic, performance and other occasions, you can wear it at night. 4 As long as the design is reasonable, the production is fine, and the adjustment afterburner is appropriate, it can correct common deformities. 5This appliance has a simple structure and is easy to make.

(2) Disadvantages: 1 Those who have no undercuts have relatively poor retention, poor results, and insufficient support. 2 The force is single, and the ability to control tooth movement is not as good as fixed appliances. Most of the tooth movement methods are tilting, and the overall movement is difficult. 3 Affects the pronunciation. Because of the relationship between the bases, the tongue is limited in motion and the speech is unclear. 4 There is a foreign body sensation, and it is troublesome to wear and wear. Patients often cannot adhere to it. Active appliances require active cooperation of patients, otherwise the effect is not good. 5 It is difficult to handle the remaining gap.

Orthosis fixed appliance

(1) Advantages: 1 Good fixation and sufficient support. 2 Can make most teeth move; overall movement, torque and twist are easy to move. 3 Can control the movement direction of the orthodontic tooth. 4 Can correct more complicated deformities. 5 Small size and more comfortable. 6 Does not affect pronunciation and speaking training. 7 The interval of clinical follow-up afterburner is long. 8 The course of treatment is short, and the patient cannot take off the appliance without wearing it, so the corrective power can be exerted continuously.

(2) Disadvantages: 1 Special attention should be paid to oral health care if the fixed appliance is used. If you cannot pay special attention to oral health care, it can easily cause dental caries and gingivitis. 2 The fixed orthodontic technology is relatively complicated, and the chairside operation time is long in the clinic, so it can only be used by experienced physicians. 3 If the strength is too large, the patient cannot remove and disassemble by himself, which may easily cause damage to the dental body and periodontal tissue, with adverse consequences.
