Study Notes

Importance of Mouth Guards (MGs)

Mouth guards are designed to absorb shocks, protecting the mouth, jaw, and face from trauma.
Approximately 50% of all sports injuries affect the oral cavity.
In contact sports, dental trauma represents 10-40% of injuries in children, predominantly impacting maxillary incisors.

Ideal Characteristics of Mouth Guards

Should cover all teeth and provide good protection without being overly thick or heavy.
Must be comfortable with minimal discomfort and should not interfere with speech or breathing.
Effective MGs have moderate shock absorption, low water absorption, and durability.

Functionality of Mouth Guards

Shock absorption minimizes the transmission of forces to teeth and other tissues.
Provides protection against hard tissue injuries, thereby reducing the likelihood of avulsion injuries.
Soft tissue injuries, such as those to lips and tongue, are also reduced.
Supports jaw protection by maintaining space and alignment, decreasing the risk of condylar fractures and concussions, ultimately protecting the brain.

Types of Mouth Guards

Type I: Preformed (Stock Type)
- Available in small, medium, and large sizes from retailers.
- Low retention and protection; no adaptability for fit.
- Unsafe due to reliance on clenching for stability.
Type II: Boil-and-Bite
- Preformed shell that can be adapted by heating and molding.
- Often inadequate with potential for poor fit and comfort, leading to risk of injuries.
- Considered as a last-minute option but may harbor fungal growth.
Type III: Custom Made (Low Vacuum)
- Requires dental visits for fitting and molding.
- Made from ethylene vinyl acetate (EVA) ensuring good retention and comfort.
- Reduces speech, breathing issues and salivation, leading to improved usage experience.
Type IV: Pressure Laminated
- Similar to Type III but manufactured under pressure; often providing a more precise fit.

Fitting Specifications for Custom Mouth Guards

Should fit snugly and not be easily dislodged by lip movements.
Thickness specifications include:
- Minimum thickness of 3mm and ideally 3-4mm for optimal energy absorption
- Never exceed 6mm to maintain effectiveness.

Considerations for Pediatric Patients

Selection of the mouth guard should be based on age, stage of development, type of sport, and financial comfort of parents.
Custom fitting is essential, especially for growing children to ensure continued effectiveness and protection.
