This study aimed to determine the positional changes in the condyle in the temporomandibular joint (TMJ) of severe skeletal Class II malocclusion patients treated with surgical-orthodontics. Materials and MethodsThe measurements of TMJ space in 97 severe skeletal Class II malocclusion patients (20 males, 77 females, mean age, 24.8 years, mean ANB = 7.41°) were assessed using limited cone-beam computed tomography (LCBCT) images acquired before orthodontics (T0) and 12 months after surgery (T1). 3D remodelling of the TMJ and measurements of the anterior space (AS), superior space (SS), and posterior space (PS) were performed to determine the position of the condyle for each joint. All data were analysed by t test, correlation analysis and Pearson correlation coe cient. ResultsThe mean AS, SS, and PS values after the therapy changed from 1.684 mm to 1.680 mm (0.24%), 3.086 mm to 2.748 mm (10.968%), and 2.873 mm to 2.155 mm (24.985%), respectively. The decreases in SS and PS were statistically signi cant. Positive correlations were found in the mean AS, SS, and PS values between the right and left sides. ConclusionsThe combination of orthodontic and surgical treatment makes the condyle move counter-clockwise in the TMJ in severe skeletal Class II patients.

“…Since then, although Dautrey and other scholars have modified it given its possible problems,20–22 there are still some problems to be solved. As a mature technology, CAD/CAM has great advantages in preoperative design and improvement of intraoperative accuracy, which has been widely used in maxillofacial surgery in recent years 23–25. Here, we further modify Dautrey’s procedure by introducing CAD/CAM technology, and evaluate its clinical effect.…”

This study aimed to introduce the clinical application of the CAD/CAM-guided modified Dautrey's procedure in recurrent anterior temporomandibular joint luxation and evaluate its clinical effects. Four selected patients were treated by the CAD/CAM-guided modified Dautrey's procedure and were followed-up to access their curative effect. Joint pain and sound, recurrence rate, mandibular function, maximum mouth opening (MMO), symptoms of facial nerve injury, and changes in zygomatic facial appearance were observed in postoperative follow-up. The followed-up period ranged from 3 months to 1 year with an average time of 7.5 months. There was no recurrence in all 4 patients, and no symptoms of facial nerve injury and zygomaticofacial appearance changes were found. All patients showed improvement in MMO, with a mean preoperative and postoperative MMO of 4.74 and 3.74 cm, respectively. All of them showed relief of joint pain or sound 3 months or more after the operation and could exercise mandibular normally. This results showed that the CAD/CAM-guided modified Dautrey's procedure was effective in the treatment of recurrent temporomandibular joint luxation and could be used as a good alternative treatment for it.
