Fixed retention: pitfalls and complications

Long-term stability of orthodontic treatment results is problematic. Long-term or even lifelong retention with bonded retainers is being increasingly used among clinicians. Bonded retainers can provide an efficient and attractive method of retention, particularly because they require minimal compliance from patients. However, the use of bonded retainers is associated with relatively frequent complications, such as detachments of the adhesive layer or wire fractures, as well as unexpected complications with potentially severe consequences with associated periodontal and general health risks. It is imperative that the whole dental team are aware of these pitfalls and complications, and appreciate how to minimise and address these. Key points Encourages balanced discussion among the dental team concerning long-term retention with bonded retainers, focusing on the possible complications associated with the use of bonded retainers. Discusses the factors influencing occurrence of complications and the potential negative effects on adjacent tissues as well as general health. Stresses the importance of monitoring bonded retainers by all members of the dental team and early interception of complications in order to prevent development of severe clinical consequences.
