Biological Aids for Orthodontic Retention- A Review

Chinchu Anna John, Roopesh R, Madhav Manoj K, Deepu Leander

Abstract: In orthodontics, post-treatment retention remains one of the greatest challenges. Orthodontic tooth movement involves mechanical stimulation and biological response. So, in addition to conventional mechanical retention, biological intervention also makes it possible to hold teeth in their newly moved position. Biological intervention makes it possible to accelerate tissue recovery post-treatment and reduce or eliminate the need for mechanical retention. This review article was aimed to discuss the effect of various biological agents on post-orthodontic stability and retention.
