Abstract
Aims: Although the conventional method for reduction of acute mandibular dislocation has been a versatile one, it occasionally fails to relocate the condyle within the glenoid fossa.
Application of heavy forces is inevitable in some clinical scenarios which potentially can cause damage to condylar structures. Moreover, the heavy force used in conventional method may be difficult for the patient to tolerate and also it can necessitate the use of adjunctive methods such as medications. The aim of this technical note is to present a novel method for reduction of acute anterior dislocation of mandibular condyle.
Technique: Standing in front of the patient, the clinician should touch the coronoid process of the mandible along the upper vestibule intraorally, slightly rotate the mandible clockwise and apply a mild to moderate backward pressure over the coronoid process. This pressure would bring about the reduction of the condyle.
Conclusion: This maneuver has been applied by the author in 130 cases and it has been successful in all cases of anterior condylar dislocation. It is very effective and simple, comfortable for the patients, does not need any equipment or medications, and eliminates the risk of damage to jaw structures.
