Fabrication of a facial shield to prevent facial injuries during sporting events: A clinical report

Flexural properties and shock‐absorbing capabilities of new face guard materials reinforced with fiberglass cloth

“…Therefore, a new technique and a more easily moldable thermoplastic resin are necessary to manufacture a FRP material with a large number of fiberglass cloth sheets. If a medical splint material with a higher softening temperature (CP or ED) were used for the experimental FRP material, we would expect the mechanical and shock absorption properties of the material to be better; however, the handling properties would be worse, and special equipment would be required for manufacturing (6–9, 11, 13, 14). Thus, the null hypothesis, in which the flexural and shock absorption properties of the 1.6‐mm‐thick experimental FRP FG materials are not significantly different from those of the 3.2‐mm‐thick commercial FG materials, was partially accepted.…”

“…Flexural properties and shock-absorbing capabilities of new face guard materials reinforced with fiberglass cloth Maxillofacial traumatic injuries sometimes occur in contact sports such as soccer, rugby football, and American football (1)(2)(3)(4)(5). The face guard (FG) has been introduced as a protective device for the early and safe return to play of athletes after sustaining maxillofacial traumatic injury, and the effectiveness of FGs has been widely recognized (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16). However, the guidelines for FG fabrication have not yet been established, and FGs have been fabricated through trial and error with materials and designs selected based on clinical usage (17).…”

Improvement of the Shock Absorption Ability of a Face Guard by Incorporating a Glass-Fiber-Reinforced Thermoplastic and Buffering Space

“…A face guard (FG) is a protector worn by an athlete that allows a speedy and safe return to play after sustaining maxillofacial traumatic injury (which can occur in contact sports [1–6]), and they are widely recognized as an effective form of treatment [7–18]. A FG must fulfill the following three requirements: (i) to protect the player from reinjury (protection ability), (ii) to avoid injury to other players (safety), and (iii) to avoid a narrowing of the player's field of vision (maintain performance) [10].…”

Avaliação de protetor nasal para atividades desportivas: análise por elementos finitos

“…Uma das soluções para evitar este afastamento é usar, durante a prática desportiva, um protetor nasal (11,12). O protetor deve evitar que, durante um impacto, o osso em processo de reparação seja deslocado ou sofra refratura.…”

“…A fratura nasal ocorre em três ocasiões: contra outro esportista, contra o solo e contra algum equipamento da quadra ou campo (3,11), entretanto a causa mais comum de fratura nasal é o impacto contra outro jogador que chega a 43%, seguido por impacto de cotovelo-cabeça e cabeça com cabeça (26) O estudo da biomecânica do impacto oferece a possibilidade de prevenção de injúrias através da otimização e aperfeiçoamento de mecanismos de proteção (28,32). Para tanto se deve saber que:…”
