At present, limited guidance is available on what retentive intervention provides the best post-orthodontic stability in the region of most concern to our patients: the labial segments. This article brings together the most recent research to draw a conclusion on which of the most common retentive devices would be considered the current best practice. While studies show some relapse is likely regardless of the clinician's choice of retention, the studies suggest that the use of a bonded retainer offers greater stability in the long term in the mandible. The data collected for the maxillary arch are of a shorter duration, as such, there is insufficient evidence to promote one method over the other.
CPD/Clinical Relevance: Dental practitioners providing orthodontic treatment need to know the best retention options available to ensure long term stability following treatment, maintaining patient satisfaction.
Article
Orthodontic treatment is defined by the Oxford Dictionary of Dentistry as the specialist branch of dentistry concerned with the growth and development of the face and jaws and the treatment of irregularities of the teeth.1 Most commonly patients have their orthodontic treatment carried out during adolescence by a specialist orthodontist in a practice or hospital setting. In more recent years, there has been an increase in adult orthodontics, in particular those seeking treatment with clear aligner treatments, such as Invisalign (Tempe, AZ, USA). Often these treatments are carried out by a general dentist. Orthodontic treatment can be broken down into an active stage and a retentive stage, both with equal importance. This review of the current literature focuses on the interventions primarily aimed at preventing displacement in the labial segments during the retentive stage. It is evident that to our patients it is the labial segments (aesthetic zone) that are of concern to them when it comes to relapse. Therefore, as clinicians, our long-term treatment success is often judged by patients as to how well this region has been retained.
