Abstract
The purpose of this paper is to outline a simple and effective digital protocol for
in-house 3D-printing of orthognathic splints for use during single-jaw orthognathic
surgery. Using this protocol, an intraoral scanner, and virtual planning software,
computer-designed splints were fabricated by a rapid prototyping machine in-house.
The protocol was utilized for 35 consecutive patients requiring single-jaw orthognathic
surgery between January 2019 and March 2020. The total time from initial scan to splint
fabrication for each case was between 5 and 9 hours, including 3 minutes for scanning of models, 4.5 minutes for development of the splint, and 4–8 hours for rapid prototyping and post-processing. This time varied based on the complexity
of the design and the number of splints printed simultaneously. The average cost of
raw materials for each splint was $0.73 Canadian dollars.
