Area of Science:

  • Digital dentistry
  • Prosthodontics
  • 3D imaging technologies

Background:

  • Traditional methods for denture replication can be time-consuming and may lack precision.
  • The need for accurate digital models of complete dentures is increasing for various clinical applications.
  • Existing digital workflows may require specialized or expensive equipment.

Purpose of the Study:

  • To describe a novel digital technique for generating a Standard Tessellation Language (STL) file of a complete denture.
  • To evaluate the feasibility of using a desktop scanner and open-source software for denture digitization.
  • To highlight the potential applications of the resulting digital denture file.

Main Methods:

  • A complete denture was scanned using a desktop scanner to capture its surface geometry.
  • Open-source software was employed to process the scanned data and generate an STL file.
  • The generated STL file served as a digital replica of the physical denture.

Main Results:

  • The described technique successfully produced an accurate Standard Tessellation Language (STL) file representing the complete denture.
  • The desktop scanner provided detailed 3D surface data of the denture.
  • The resulting digital file is a precise duplicate of the scanned denture.

Conclusions:

  • This digital technique offers an accessible method for creating Standard Tessellation Language (STL) files of complete dentures.
  • The generated digital denture files have significant potential for applications such as surgical implant placement planning.
  • The technique facilitates the fabrication of duplicate dentures and the long-term digital archiving of denture data.
