Management of condylar resorption before, during, and after orthognathic surgery

This prospective study selected 21 patients who underwent orthognathic surgery for bite correction. Study selection included preexisting CBCT condylar resorption and class II malocclusion. No patient was dropped from the study.

Bimaxillary counter clockwise advancements were accomplished following treatment planning as described by A rnett . The average advancement at ANS was .62 mm, maxillary incisor 6.73 mm, mandibular incisor 12 mm, and Pogonion 22.5 mm. The mandibular occlusal plane decreased from an average of 109–93°. No concomitant TMJ surgery was done.

Surgical techniques were utilized to minimize post surgical mandibular relapse including, pre and post surgical TMJ medical management , non-compressive condylar seating , short BSSO splitting technique, BSSO mini plating without clamping , and postsurgical skeletal and Class II elastics.

The patients were followed for a minimum of 12 months post surgically. At longest time point (average 36 months) all patient were without TMJ pain, had normal opening range, and had clinically stable occlusions.
