Intra-Oral Flap Splint Fabrication: A 3D Printing and Digital Impression Approach.

Intra-oral flaps serve as a valuable solution for small to medium-sized oral cavity defects, yet complications such as flap sagging, tension at suture lines, mastication-related injuries, and patient discomfort remain challenges. The use of intraoral splint to support the flap diminishes these risks and complications. Conventional intraoral impression techniques are fraught with risks, including impression material infiltration and muco-compression, compromising blood supply. To overcome these challenges, the integration of digital impressions and 3D printing offers a novel solution for fabrication of intraoral splint.
