A computer vision technology or a three-dimensional scanning technology is adopted to detect the consistency of the size and shape of a produced finished product and the three-dimensional model; and digital try-on is performed through an augmented reality (AR) technology, so that rapid adjustment of various parameters of the product is realized.

A template for positioning perforations to be made in dams, characterized by standardized markings for well-aligned dental arches and a curved millimeter ruler to customize the position for perforations in irregular dental arches, as well as coordinate lines and midlines, which allow tooth segmentation to be performed to position the perforation. This template allows for varying positions and distances when making perforations in latex and silicone (synthetic) dams, facilitating its use in patients with irregularly aligned dental arches. It can also be used on dams of different thicknesses (thin, medium, and thick), especially since it facilitates varying the distances and positions of the perforations.
