Abstract :
Background: What is now known as a Class-III malocclusion was initially recognized by Pierre Fauchard. True Class-III malocclusion is a genetically based condition that manifests in childhood. As the youngster reaches the teenage growth spurt, it becomes more obvious. Typically, we will discover a parent or grandparent who is dealing with the same issue. Class-III malocclusion, however, is not a disease. The abnormality itself is a compensatory mechanism to make up for variation that has happened at some point during the course of the individual's development.
Case Report: The case presented here demonstrates the importance of presurgical decompensation, surgical planning, including cephalometric predictions, and mock surgery in the management of severe skeletal Class-III malocclusion. The treatment included comprehensive orthodontic and surgical workup that included bilateral sagittal split osteotomy for mandibular setback of 3mm and LeFort-I osteotomy for maxillary advancement of 3mm.
Results: Class-I jaw relationships with a pleasing profile and correctly aligned arches were attained after 2 years of detailed treatment. This led to an aesthetic improvement and a significant increase in the patient's confidence.
Conclusion: Class-III skeletal malocclusions can be corrected surgically or through camouflage. However, an ortho-surgical approach may be necessary if the issue cannot be resolved with orthodontics alone. When done correctly, bi-jaw surgery has repeatedly been shown to be quite successful.
