Graphical depiction of the process by which the stent is created from the 3D CAD maxillo-mandibular model. a) The rectangular template is overlaid with the mandibular and maxillary dentition to ensure coverage of the entire occlusal surfaces. b) The digital impression of the dentition with the selected incisal opening is created through Boolean subtraction of the patient’s dental anatomy from the template. c) Removal of the excess material to produce a mouth-opening, tongue-depressing stent. d) Smoothing of the external surfaces of the stent created in c) to produce the final product ready for 3D printing
