Eligibility

Inclusion criteria

Inclusion criteria: The present study included 16 clinically healthy patients, all classified as Angle class II, in whom control CT scans had been obtained at an interval of 6 to 72 months after surgery. All cases had undergone prior orthodontic preparation with a view to orthognathic surgery

Exclusion criteria

Exclusion criteria: Patients with syndromic dentofacial deformities; asymmetries; postoperative follow-up of less than 6 months were excluded
