Dear Doctor, Thank you for your inquiry. We would like to inform you that WEBCEPH does not use Holdaway VTO for treatment simulation predictions. The ratio of soft tissue movement to skeletal movement in WEBCEPH is as shown in the attached image; however, the exact numerical values of this ratio are not disclosed at this time. We appreciate your interest in WEBCEPH. Sincerely, WEBCEPH

Dear doctor, thanx for asking. The soft tissue predictions in the Lateral Face tab of WEBCEPH are not directly based on a specific researcher's analysis, such as the Holdaway analysis. Instead, they are derived from a combination of selected measurements that are deemed helpful for soft tissue analysis. I hope this answer is helpful. Thank you very much.

Dear doctor. Thank you for your inquiries. We will study the Holdaway analysis method and see if it can be added. Thank you for your valuable opinion.
