Abstract
Infraocclusion of a primary molar is a relatively common occurrence which seldom leads to serious complications, particularly when the succedaneous permanent tooth is present. Despite the relative infrequency of unfavorable outcomes, an infraoccluded primary molar may be associated with other dental anomalies, including hypodontia. If diagnosis is delayed, infraocclusion of a primary molar can become severe, with associated negative effects on the adjacent teeth and alveolar bone. This emphasizes the need for routine and periodic orthodontic assessment of growing patients. Any deviation from the normal eruption sequence of teeth should be diagnosed and managed in a timely manner, to preserve dental arch integrity and reduce the potential for undesirable outcomes. This case report demonstrates how comprehensive assessment of the dentition, logical treatment planning and careful management of challenging orthodontic tooth movements can combine to provide a pleasing treatment outcome.
