Prevalence oftrauma 1. In children, sports accidents reportedly accountfor 10-39% of all dental injuries. (Newsome, 2001) 2. Peak incidence of 8 to 11 years. 3. Boys are more likely to incur injuries than girls 4. Patients with an increased overjet and proclined upper incisors are more prone to trauma. (Todd & Dodd, 1983) 5. Injury to the maxillary incisors is very common and can account for as much as 80% of all cases. (Cavalleri &Zerman, 1995) Materials 1. Ethylene vinyl acetate (EVA) 2. Polyvinylchloride (PVC) material (Similar to Pressure Form Retainer). 3. Rubber base silicon.

Orthoguards They are the most recent addition to the market They have an instant fit with an incorporated channel to accommodatea fixed appliance and any potential tooth movements. Which mouthguard should I recommend? The literature does not provide clear evidence on which type of mouthguard should be recommended for orthodontic patients with fixed appliances. It is suggested that custom-formed laminate mouthguards with their greater number of layers and thickness have led to greatly improved orofacial protection. (Salam, 2008) Recommendations: All orthodontic patients wearing fixed appliances, who participate in contactsports, should wear a sports mouthguard to protect against possible dental injury.
