Brief Summary

A 3D printed intraoperative occlusal splint is a custom-made biocompatible resin guide that allows surgeons properly align a patient's upper and lower dentition during surgery. This alignment further places maxilla and mandible into proper position. An occlusal splint contains outlines maxillary and mandibular dentition allowing the teeth to lock into place with correct alignment. At Johns Hopkins, traditionally hand-made and industry-made 3D printed splints have been used safely. However, prior studies have demonstrated the ability of in-house 3D prints to save time and money compared to industry. In-house models are similarly produced with FDA-clear, biocompatible resin for 3D printing, and maintain equivalent safety for patients compared to industry-made models.
