Area of Science:

  • Biomedical Engineering
  • Oral and Maxillofacial Surgery
  • Additive Manufacturing

Background:

  • Rapid prototyping (RP) is increasingly utilized in oral and maxillofacial surgery for creating physical models.
  • Ensuring the accuracy of these RP models is critical for effective surgical planning and execution.

Purpose of the Study:

  • To investigate and quantify dimensional errors in medical RP models.
  • To identify specific factors contributing to inaccuracies throughout the RP production process.

Main Methods:

  • Conducted 16 linear measurements on a dry skull, a 3-D visual (STL) model, and the final RP model.
  • Analyzed errors stemming from volume averaging, threshold values, and landmark replication.
  • Examined the 'dumb-bell effect' and differences in error for internal versus external measurements.

Main Results:

  • The absolute mean deviation between the dry skull and the RP model was 0.62 ± 0.35 mm (0.56 ± 0.39%).
  • This deviation is lower than previously reported values, indicating improved accuracy.
  • The impact of threshold values on measurement error varied between internal and external measurements.

Conclusions:

  • RP technology can produce medical models with high dimensional accuracy suitable for oral and maxillofacial surgery.
  • Understanding and mitigating production-phase errors, such as threshold effects, is key to optimizing RP model fidelity.
  • Further research into the 'dumb-bell effect' can refine RP processes for even greater precision.
