Abstract
This case report describes an orthognathic resurgery retreatment of a patient with open bite and temporomandibular
joint disorder (TMD). A 19-year-old woman had been referred to the orthodontic department due to the relapse of
anterior open bite. She had undergone mandibular orthognathic surgery without any orthodontic treatment 3 years ago
for open bite correction. Afterwards, she had been treated for TMJ osteoarthritis with medication, intra-joint injection,
and a TMJ stabilizing splint. However, she still complained about the anterior open bite and sole occlusion of the
second molar, causing difficulty to chew. To correct the open bite and improve facial esthetics, we performed Le Fort
I and bilateral sagittal split ramus osteotomy followed by orthodontic treatment. After 18 months of the total treatment
period, the patient's facial profile and functional occlusion were improved by establishment of harmonious facial
vertical heights.
