Introduction: The effects of rapid palatal expansion on condylar response is not described very well. The purpose of this review is to describe whether rapid palatal expansion has an influence on the condylar position. Methods: This review article describes the three main types of expanders namely Rapid palatal expansion (RPE), mini-screw assisted rapid palatal expansion (MARPE), and surgically assisted rapid palatal expansion (SARPE) and their effects on condylar position from the current literature. Results: The palatal expanders can have an effect on the Class II malocclusion patients in helping to decrease the overjet in some patients. It also helps in the lowering the nasal resistance and increases the airway volume. The palatal expanders can lead to molar extrusion which results in increased joint spaces in the temporomandibular joint and an alteration of condylar position. Conclusions: The design of expanders can influence the effects on dentition such as molar extrusion, the joint space, and the condylar position. Dentists and orthodontists can have a better discernment of effects of expanders and condylar position by understanding in detail the effects of the palatal expanders on occlusal alterations and condylar position.
