      Fabrication of a definitive obturator from a 3D cast with a chairside digital scanner for a patient with severe gag reflex: a clinical report.
      recently published a step-by-step technique for fabricating obturator prostheses by using a chairside digital scanner and conventional impressions. However, the demarcation described between the printed cast and the bulb portion, from a conventional impression used to generate a definitive cast, raises some concerns about the complexity of the technique, specifically, whether definitive casts can be combined easily.
