This study was designed to determine if a remedial program using a bite-block device could inhibit hypermandibular activity (HMA) and thereby improve the lingua-alveolar valving (LAV) abilities of four school-age children who demonstrated multiple lingua-alveolar (LA) phonemic errors. The results revealed significant improvements in LAV and LA phoneme articulatory skills in all of the children who used the bite-block device to reduce HMA subsequent to comprehensive training sessions.
