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.
患者因现有义齿过度磨损和折断，需要更换上颌全口可摘义齿和下颌种植体支持的全口覆盖义齿，我们为其制定了治疗方案。我们采用数字化工作流程，由整块丙烯酸树脂盘铣削制作义齿。交付义齿时，患者表示即使没有被诊断为阻塞性睡眠呼吸暂停，他也无法在不佩戴义齿的情况下入睡。在强调建议其睡觉时取下义齿后，我们决定使用增材制造技术，因为其成本低，并且能够以各种生物相容性材料忠实地复制三维文件。第二副睡眠义齿通过 3D 打印制作并交付，只需进行最小的调整，成本也很低。
