Digital model setup for fabricating mouthguards for the orthodontic patient: A cutting-edge report

Abstract

Objective:

This cutting-edge report presents a technique for virtually preparing the orthodontic patient’s model for fabrication of an individualised sports mouthguard.

Technique:

Using the stereolithography (STL) file from an intraoral scan, a step-by-step guide to trim the model and prepare it for three-dimensional (3D) printing, using free software (Meshmixer; Autodesk Inc., San Francisco, CA, USA), is provided. This method employs a 3D drawing tool to create a buffer space between the teeth, orthodontic appliance and mouthguard material before printing. The purpose of the buffer space is to accommodate minor tooth movements, ensure proper protection and improve the mouthguard’s lifespan.

Conclusion:

Orthodontic patients should wear mouthguards during sports activities to protect orofacial structures. The proposed method successfully prepares a 3D-printed model with a buffer space, which can be used to fabricate an effective sports mouthguard. While familiarity with 3D-modelling software is required, this method can enhance mouthguard fabrication and minimise potential distortions inherent in traditional impression techniques using alginate or other materials.
