Case 1. (a) The common cephalometric appearance of idiopathic condylar resorption includes class II skeletal and occlusal relationships, anterior open bite, steep occlusal and mandibular plane angles, and overangulated lower incisors. (b) The surgical treatment objective (prediction tracing) demonstrates the orthognathic procedures required to achieve a good functional and aesthetic result, including maxillary and mandibular osteotomies with counterclockwise rotation of the occlusal plane and augmentation genioplasty.
