Abstract
Fixed retainers in orthodontics have shown to have excellent results for the stability and durability of the treatment. Despite this, it has been observed that there are certain unwanted tooth movements totally different from a recurrence to its initial position prior to orthodontic treatment. The so-called “twist effect” is one of them and is characterized by an inclination in opposite directions of the contralateral canines, where one presents an inclination towards the vestibular and the other towards the lingual or palatine. It occurs mainly in the jaw, despite the fact that the retainer remains perfectly attached to the teeth. The objective of this bibliographic review is to evaluate the different factors reported in the literature that may be related to the appearance of the “turn effect” and how relevant they may be in its development. In conclusion, it is important to consider the multifactorial nature of this type of complications, where the type and quality of the wire used for containment, together with the patient’s periodontal characteristics, have shown some involvement in its genesis, therefore, It is essential to make patients aware of the importance of periodic orthodontic check-ups after the removal of fixed appliances to monitor and control the occlusal results achieved and the status of the installed retention devices.
