Background
The orthodontic treatment of patients with idiopathic condylar resorption (ICR) remains controversial. The effect of molar intrusion using temporary anchorage devices (TADs) and the consequential gradual counterclockwise rotation of the mandible in patients with ICR remains unclear.
Aims
To present the long-term treatment result of an adult skeletal Class II open-bite malocclusion with a history of ICR corrected by the combination of orthognathic surgery and TADs.
Methods
After six months of occlusal splint therapy, a surgically-assisted intrusion of the maxillary molars was performed using TADs, followed by a bilateral sagittal split osteotomy (BSSO) and genioplasty.
Results
The five-year post-treatment records showed a good facial appearance, occlusion and mandibular/condylar position with no progress in the condylar resorption.
Conclusion
Based on a single case, this treatment option is an effective alternative to a bimaxillary osteotomy for patients presenting with ICR.
