Mouthguards are used for protection to prevent and reduce injury to teeth. Among various types of
mouthguards, custom-fitted ones provide the best protection. However due to their high manufacturing
time and cost and unsuitability to be designed parametrically, existing custom-fitted mouthguards are
not practical enough. 3D printing technology offers new possibilities to overcome these issues. For
this purpose, a methodology is developed in which a parametrically designed mouthguard is to be
created using data from a 3D scanned teeth model of a person to manufacture by a 3D printer. Coronal
and apical boundary curves for both buccal and palatal sides of teeth are offset away from the teeth
surface to create the outer surface of the mouthguard between these curves and surface of the scanned
teeth are used for the inner surface of the mouthguard. The 3D printing techniques and materials that
can be used to manufacture the highly customized parametric mouthguard design are investigated. The
performance of the designed mouthguard model is investigated using finite element (FE) analysis
under the injury loading conditions.
