Custom sports mouthguard modified for orthodontic patients and children in the transitional dentition

Young athletes with ever-changing transitional dentitions and those wearing fixed orthodontic appliances can benefit from custom-formed protective mouthguards. Modifications of the traditional vacuum-forming method are useful to fabricate mouthguards for such patients and extend the useful life of these devices. The purpose of this case report is to document fabrication of custom-formed protective mouthguards for a 10-year-old boy wearing fixed orthodontic appliances and a 9-year-old girl with a fixed palatal expander in place.
