Background:
Over the last decade, the accuracy of 3D computer-assisted orthognathic surgery has been extensively investigated. However, patient-reported outcome measures have been rarely reported for this technology. This study aimed to assess quality of life following orthognathic surgery using CAD/CAM bone splints compared to the classic occlusal wafers in patients with dentofacial deformities.
Methods:
Thirty-two patients were randomly allocated into two groups where group I utilized CAD/CAM splints and patient specific osteosynthesis for maxillary positioning and group II utilized occlusal wafers fabricated on a semi-adjustable articulator. Patients were assessed using orthognathic quality of life Questionnaire (OQLQ) preoperatively and 6 months postoperatively.
Results:
Mean OQLQ overall score change of 24.375±11.96 took place in group I patients while group II showed a mean change of 23±8.39.
Conclusions:
The study showed evident improvement in quality of life following orthognathic surgery compared to before surgery. However, computer-assisted surgery did not show any significant improvement over the classic approach.

Quality Control
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...
