Abstract

Objective

To explore the technology of combination with computed tomography (CT), computer aided design (CAD), finite element analysis (FEA), and Selective Laser Melting (SLM) in manufacturing a titanium custom-fitting surgical guide well matched with the patient mandible in order to realize mold-free manufacturing.

Methods

A model of a custom-fitting surgical guide was built by CT scanning machine and Solidworks software, and then the model was imported into Ansys software to carry out simulation analysis with nonlinear contact method. Finally, the model above was imported to SLM molding equipment, the titanium custom-fitting surgical guide was proposed via titanium powder melted with layer by layer using a high-speed scanning galvanometer.

Results

The maximum equivalent stress of the mandible and surgical guide was distributed uniformly and reasonably, the titanium custom-fitting surgical guides formed by SLM molding equipment provided high accuracy and high density.

Conclusion

The combination of CT, CAD, FEA, SLM technology can fulfill mold-free manufacturing of surgical guides and the manufacturing cycle is shorten as well.
