Clear aligner treatment and the generation of posterior open bites: Aetiology,treatment and prevention

Abstract

A frequent and well-documented issue that is seen with clear aligner treatment (CAT) is the development of posterior open bites. The theories of posterior open bite development are discussed, and the treatment and prevention of each aetiological factor are outlined. Predictable prevention and management of posterior open bites during CAT would serve to improve treatment outcomes and patient satisfaction both aesthetically and functionally.

Clear aligner treatment and the generation of posterior open bites: Aetiology, treatment and prevention

There has been a rapid rise in orthodontic treatment provision using clear aligners. Clear aligners can be successfully used to align teeth and correct issues with the bite. However, undesirable changes may also occur, and one well-documented issue with clear aligners is the development of open bites around the posterior teeth. There are many theories as to why posterior open bites develop, and these are discussed. Suggestions for treatment and prevention of each aetiological factor are outlined. It is hoped that predictable prevention and management of posterior open bites during clear aligner treatment would improve treatment outcomes and patient satisfaction.
