In implant dentistry, scan templates, also known as scan appliances or radiographic guides, are fabricated according to patients' anatomy, and later on transferred into surgical guides through CT scan, image segmentation, surface reconstruction, CAD modification, and manufacturing. This approach may be also applied to other kinds of surgery. The final manufactured surgical guides can hardly match the actual geometry of the initial scan templates, thus cannot fit well into patients' mouths, which can pose serious risks for surgery.This invention introduces calibration features to design and make a scan template, and accordingly the workflow to perform treatment planning with the template. Calibration features are geometric form features or their patterns. Iterations are utilized to make sure the reconstructed model of a scan template can replicate or match with the calibration features. After treatment planning, calibration features are removed from the model (an optional step), and a surgical guide is designed and fabricated. This invention also includes some special calibration feature designs. The treatment planning workflow is greatly improved with calibration features introduced.
