Area of Science:

  • Dentistry
  • Biomaterials Engineering
  • Digital Manufacturing

Background:

  • Patient required replacement of maxillary complete removable denture and mandibular implant-retained complete overdenture due to excessive wear and fracture.
  • Initial prostheses were fabricated using a digital workflow and milled from a monolithic acrylic resin disk.

Purpose of the Study:

  • To evaluate the use of additive manufacturing (3D printing) for creating low-cost, well-fitting sleeping dentures.
  • To address a patient's difficulty sleeping without dentures, despite no diagnosis of obstructive sleep apnea.

Main Methods:

  • A digital workflow was employed for the initial denture fabrication.
  • The second set of dentures, specifically for sleeping, were created using additive manufacturing (3D printing).
  • Biocompatible materials were utilized for the 3D-printed dentures.

Main Results:

  • The initial milled dentures required adjustments and the patient experienced discomfort when not wearing them.
  • The 3D-printed sleeping dentures were delivered with minimal adjustments.
  • Additive manufacturing proved to be a low-cost method for reproducing the 3D file accurately.

Conclusions:

  • Additive manufacturing is a viable, cost-effective technology for fabricating custom sleeping dentures.
  • 3D printing offers a solution for patients with specific needs regarding denture wear during sleep.
  • This digital workflow enhances patient comfort and treatment outcomes in prosthodontics.
