Rapid maxillary expansion: a clinical insight for the general dental practitioner

Rapid maxillary expansion is an orthodontic treatment approach for corrections of transverse discrepancies, such as crossbites. Rapid maxillary expansion expands the palate by applying forces to the teeth and surrounding tissues to separate the mid-palatal suture, allowing for the correction of the indicated malocclusions. A general dental practitioner should be aware of the indications, treatment strategy and play an important role in the timely referral of patients for orthodontic assessment. This article offers a comprehensive overview of rapid maxillary expansion, expansion protocols, and an in-depth analysis of the prevalent characteristics associated with expansion, along with evidence-based recommendations for effective management. CPD/Clinical relevance: This paper aims to give the general dental practitioner clinical insight into rapid maxillary expansion, the devices used and the indications for use.
