The result of mandibular molar passive extrusion in orthodontic treatment is associated with leading to occlusal discrepancies. Passive extrusion refers to the movement of a tooth in the occlusal direction without active force applied to it. When mandibular molars undergo passive extrusion, they may become misaligned with adjacent teeth and the opposing maxillary teeth due to altered occlusal relationships. This misalignment can create discrepancies in the overall bite, leading to issues such as interference during occlusion and an imbalance in the dental arch relationships.

In the context of orthodontics, maintaining proper occlusion is crucial for functional and aesthetic outcomes. Passive extrusion can disrupt this balance, causing further complications in the treatment plan or affecting the patient's ability to occlude properly. Therefore, understanding the implications of passive extrusion on occlusal relationships is important for effective orthodontic management.
