What this site is for
It exists to separate what is established about three-dimensional planning from what is claimed, and to grade each honestly rather than presenting the subject as settled in either direction. That is why every claim is placed in one of four groups, why regulatory status is reported as its own question, and why the limits of the evidence are stated alongside the findings.
What it deliberately does not do
It does not recommend for or against an operation, and it does not invite a reader toward an assessment or a consultation. It is not a booking page and it offers no service in relation to anything it describes. It does not name brands of software, guide systems or implants, does not quote prices, and does not present a planning method as the standard of care on the strength of a marketing sentence.
The facts kept visible
Three facts are repeated wherever they are relevant. A virtual plan makes a bone position reproducible, and that is the strongest finding in the field. A rendered simulation is a drawing of a plan rather than a forecast of a face. And the software, the printed guide and the patient-facing image sit in three different regulatory classes, so an approval of one is not an approval of another.
How the content is reviewed and corrected
Tongchun Mao, MD, Deputy Director and Head of Aesthetic Surgery, is the responsible physician. This subject moves on a faster clock than most, because software and clearances change more often than the underlying evidence does, so the review is dated and revisited on a short cycle rather than treated as a settled text. If you find something unclear, out of date or wrong, the contact page explains how to tell us, and the correction is made to the page itself.
