3D Printed Models in 3D Virtual Treatment Planning of Orthognathic Surgery

Completed

• Conditions: Orthognathic Surgery

• Registration Number: NCT03986723
• Lead Sponsor: AZ Sint-Jan AV

Brief Summary

Despite the shift from 2D towards 3D virtual treatment planning of orthognathic surgery, traditional plaster cast are still gold standard. The investigators aimed to compare the overall reliability and time efficiency of an digital workflow using 3D printed models, in comparison to the conventional plaster workflow.

Twenty real-life cases were planned according to both workflows and timed by a single resident.
