Area of Science:

  • Sports Dentistry
  • Biomaterials Engineering
  • Trauma Prevention

Background:

  • Mouthguard thickness is crucial for preventing orofacial injuries during sports.
  • Maintaining optimal mouthguard thickness post-fabrication presents challenges.
  • Evaluating novel fabrication methods is essential for improved protective equipment.

Purpose of the Study:

  • To assess a pressure-forming technique using a modified single-mouthguard sheet.
  • To determine if altering the sheet geometry impacts final mouthguard thickness and fit.
  • To optimize mouthguard fabrication for enhanced sports safety.

Main Methods:

  • Ethylene vinyl acetate sheets (3.8 mm) were prepared, with one group having its anterior margin cut.
  • Sheets were heated and pressure-formed, with displacement measured.

  • Mouthguard thickness was measured at the incisor and molar regions.
  • Mouthguard fit was assessed by measuring the gap between the mouthguard and a dental model.
  • Two-way ANOVA was used to analyze differences in thickness and fit.

    • Main Results:

    • Mouthguard thickness significantly varied across measured regions (P < .01).
    • The greatest thickness was observed at the central incisor's labial surface in mouthguards made from cut sheets (P < .01).
    • No significant difference in mouthguard fit was found between the original and cut sheets.

    Conclusions:

    • The pressure-forming method using a single, modified mouthguard sheet can produce adequate thickness.
    • Cutting the anterior part of the sheet is a viable strategy to optimize mouthguard thickness.
    • This technique offers a practical approach to fabricating effective mouthguards for sports protection.
