Purpose:
The purpose of this study was to observe long-term osseous healing of the cleavage space between bone fragments after intraoral vertical ramus osteotomy using computed tomographic (CT) values.
Patients And Methods:
CT examinations were performed to observe long-term osseous healing immediately after intraoral vertical ramus osteotomy and at 6 months, 1 year, and 2 years postoperatively. Bone fragments were observed on the interior and lateral sides. CT values between bone fragments were used to measure the range of each point within a 1.7- × 1.7-mm square, and the mean of the measurements was calculated.
Results:
CT values between bone fragments increased significantly over time at 1 month, 6 months, 1 year, and 2 years after surgery.
Conclusions:
Osseous healing in the cleavage between bone fragments after intraoral vertical ramus osteotomy was successful according to CT values.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
