Stress Distribution Pattern of a Calculated Standardized Force on Maxillary and Mandibular Jaws with Proclined Maxillary Anterior Teeth with and without the Use of Mouthguard: A 3D Finite Element Analysis

Abstract

A bstract Aim To evaluate the stress distribution of calculated standardized force on maxillary and mandibular jaw bones with proclined maxillary anterior teeth with and without the use of a mouthguard. Materials and methods It's a finite element analysis (FEA) study. Maxillary and mandibular jaw models with and without mouthguard (4 mm) were created using a cone-beam computed tomography (CBCT) scan of a 13-year-old male patient with proclined maxillary anterior teeth. Calculated standardized forces were applied on the maxillary central incisors in the horizontal direction of the created model. The von Mises stresses (MPa) were analyzed on the maxillary and mandibular jaw. Results Higher von Mises stresses were analyzed in the maxillary and mandibular jaw model without a mouthguard compared to the model with a mouthguard. Forces were more evenly distributed in the maxillary and mandibular jaw models with a mouthguard. Conclusion A mouthguard can be used to reduce and evenly distribute the stress on the maxillary and mandibular jaw with proclined maxillary anterior teeth when exposed to real-life situation forces. Clinical significance The force of injury is influenced by the size of the object or the velocity at which the athlete hits the object/individual. There is a need to evaluate the force at which the individual athlete hits the object/surface based on average height, weight, and velocity/performance at that particular age. As the age of the athlete's advances, there is a change in the height, weight as well as performance. This factor will influence the impact and severity of the trauma caused during sports activities. So, these parameters should be considered while designing the mouthguard for its better effectiveness. How to cite this article Doiphode AR, Kalaskar R.
