Area of Science:

  • Biomaterials Science
  • Dental Technology
  • Orthodontics

Background:

  • Vacuum-formed mouthguards are commonly used for protection in sports and orthodontics.
  • The fabrication process, particularly heating temperature, can significantly impact the physical properties and fit of mouthguards.

Purpose of the Study:

  • To investigate the effect of different heating temperatures on the thickness and fit of vacuum-formed mouthguards.
  • To determine the optimal heating temperature for fabricating high-quality mouthguards.

Main Methods:

  • Mouthguard sheets (3.8 mm ethylene vinyl acetate) were vacuum-formed at 80°C, 100°C, and 120°C.
  • Mouthguard thickness was measured at specific anatomical landmarks (central incisor, first molar).
  • Mouthguard fit was assessed by measuring the marginal gap at the cervical margin.

Main Results:

  • Mouthguard thickness varied significantly across different regions and temperatures (P < 0.01).
  • The highest thickness was observed at the labial surface of the central incisor and buccal surface of the first molar when fabricated at 120°C (P < 0.05).
  • Optimal mouthguard fit was achieved at a heating temperature of 120°C (P < 0.05).

Conclusions:

  • A heating temperature of 120°C is recommended for fabricating vacuum-formed mouthguards to ensure optimal thickness and fit.
  • Precise control over heating temperature during fabrication is essential for producing effective mouthguards.
