The reported prevalence of maxillary advancement following class III surgeries is around 45-50%. This statistic stems from various clinical studies and reviews that assess the outcomes of surgical interventions for patients with class III malocclusion, which typically involves a deficiency of the maxilla in relation to the mandible.
Class III surgical corrections often include procedures such as maxillary advancement (Le Fort I osteotomy) to achieve better alignment of the dental and facial structures. The specific range provided reflects the number of patients who experience some degree of maxillary advancement as part of their surgical treatment plan. This prevalence is significant, as it indicates that a substantial proportion of patients undergoing class III surgery may require this advancement to achieve optimal functional and aesthetic results.
Factors that play a role in the variation of maxillary advancement include the severity of the malocclusion, the specific surgical techniques employed, and the individual anatomical considerations of the patient. Understanding this prevalence is crucial for orthodontic professionals, as it informs treatment planning and helps set realistic expectations for patient outcomes.
