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.
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.
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.
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.
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.

评估在有和没有使用护齿器的情况下，对上颌前牙前倾的上颌和下颌颌骨施加计算出的标准力时的应力分布情况。
这是一项有限元分析（FEA）研究。使用一名13岁上颌前牙前倾男性患者的锥形束计算机断层扫描（CBCT）创建了有和没有护齿器（4毫米）的上颌和下颌模型。在创建模型的水平方向上，对上颌中切牙施加计算出的标准力。分析上颌和下颌的冯·米塞斯应力（MPa）。
与使用护齿器的模型相比，未使用护齿器的上颌和下颌模型中分析出更高的冯·米塞斯应力。在使用护齿器的上颌和下颌模型中，力分布得更均匀。
当暴露于现实生活中的作用力时，护齿器可用于减少并均匀分布上颌前牙前倾的上颌和下颌颌骨上的应力。
受伤力受物体大小或运动员撞击物体/个人的速度影响。有必要根据特定年龄的平均身高、体重和速度/表现来评估个体运动员撞击物体/表面的力。随着运动员年龄的增长，身高、体重以及表现都会发生变化。这个因素会影响体育活动中造成的创伤的冲击力和严重程度。因此，在设计护齿器以提高其有效性时应考虑这些参数。
