Area of Science:

  • Dentistry
  • Digital Dentistry
  • Prosthodontics

Background:

  • Complete arch fixed implant restorations require precise digital workflows.
  • Accurate superimposition of digital scans is crucial for complex prosthodontic cases.
  • Traditional methods can be challenging due to the absence of stable intraoral landmarks.

Purpose of the Study:

  • To present a complete digital workflow for fabricating complete arch fixed zirconia implant restorations.
  • To demonstrate a novel technique for accurate digital model superimposition.
  • To overcome challenges associated with limited intraoral landmarks in digital dentistry.

Main Methods:

  • Utilized an intraoral scanner and a double digital scanning technique.
  • Employed a novel scan body and impression pin for accurate data capture.
  • Digitally designed, fabricated, and verified prosthesis prototypes before definitive fabrication.

Main Results:

  • Achieved accurate and reproducible superimposition of Standard Tesselation Language (STL) files.
  • Successfully fabricated and delivered definitive zirconia prostheses using the digital workflow.
  • Demonstrated the technique's applicability in both arches, regardless of landmark stability.

Conclusions:

  • The presented digital workflow enables precise fabrication of complete arch fixed zirconia implant restorations.
  • The novel scanning technique and components facilitate accurate superimposition of digital models.
  • This workflow offers a reliable solution for complex implant prosthodontic cases, even with limited intraoral landmarks.
