      A patient presented with a treatment plan for the replacement of his maxillary complete removable denture and mandibular implant-retained complete overdenture because of excessive wear and fracture of his existing prostheses. A digital workflow was used, and his dentures were milled from a monolithic acrylic resin disk. Upon delivery of the dentures, the patient reported that he was unable to sleep without his dentures in place although he denied a diagnosis of obstructive sleep apnea. After emphasizing the recommendation to remove his dentures while sleeping, it was decided to use additive manufacturing technology because of its low cost and ability to faithfully reproduce a 3-dimensional file in various biocompatible materials. The second set of sleeping dentures were 3-dimensionally printed and delivered with minimal adjustment and at a low cost.
