CA typical treatment for incorrectly positioned teeth malocclusion takes about 1 to 3 years to complete, with braces being altered slightly every 4 to 10 weeks by the orthodontist. Multiple methods exist for adjusting malocclusion. In growing patients there are more options for treating skeletal discrepancies, either promoting or restricting growth using functional appliances, orthodontic headgear or a reverse pull facemask. Most orthodontic work is started during the early permanent dentition stage before skeletal growth is completed. If skeletal growth has completed, jaw surgery can be an option. Sometime teeth are extracted to aid the aid the orthodontic treatment (teeth are extracted in about half of all of cases, most commonly the premolars.
Orthodontic therapy can include the used of fixed or removable appliances. The majority of orthodontic therapy is delivered using appliances that are fixed in place, for example with braces that are bonded to the teeth with adhesives. Fixed appliances can have a greater mechanical control of the teeth and the treatment outcome is greater with the use of fixed appliances.
Fixed appliances are for example used to rotate teeth that don’t fit to the arch shape of the other teeth, to move multiple teeth to different places, to change the angle of teeth, or to change the position of the root of the tooth. It is not preferable if the patient has poor oral hygiene (as that can result in decalcification, tooth decay, and other problems), if the patient isn’t motivated (as treatment lasts several months and commitment to oral hygiene is required), or if the malocclusions are mild.
