Point-of-care three-dimensional printing for craniomaxillofacial trauma

Abstract

Computer-aided design, three-dimensional printing, and additive manufacturing are revolutionizing craniomaxillofacial trauma surgery. Traditionally, this is completed via third-party vendors during online web meetings. Although this is effective, it can take several weeks to have custom plates arrive, negating its use in acute facial trauma. The price of 3D printers and software needed to complete this in-house are decreasing. This allows for expedited turn around, facilitating treatment in the acute setting. This article serves as a review of fundamental 3D printing principles and describes the process of virtually reducing facial fractures, 3D printing the reduced models, and having a plate ready for surgery in hours.

Point-of-care computer-assisted design and manufacturing technology and its utility in post-traumatic mandibular reconstruction: An Australian public hospital experience

“…The manufacturing delay associated with external vendors is another limitation of 3D-printed surgical guides and other patient-specific instruments, something that likely inhibits its uptake in the acute trauma setting. 7 In a series of five patients undergoing acute mandibular trauma reconstruction, the average interval between injury and availability of an externally milled custom plate was 7 days. 5 By utilising an in-house 3D printer for construction of a point-of-care surgical guide and model, we have been able to efficiently use generic reconstruction plates pre-bent with accuracy.…”

“…However, the reliance on third-party manufacturers comes with significant drawbacks, notably increased financial costs and manufacturing delays. 6,7 Using a case of complex mandibular fracture non-union, we will illustrate our approach to producing point-of-care three-dimensional (3D)-printed surgical models to aid with the application of mandibular reconstruction plates. We use a custom 3D-printed surgical model to pre-contour the plates, allowing them to be positioned via a transoral approach.…”
