RESUMEN
<p><b>OBJECTIVE</b>An electric monitor of bruxism had been invented in order to evaluate the curative effect of cuspid occlusal upheaving splint and stabilization splint.</p><p><b>METHODS</b>20 patients with bruxism were randomly divided into two groups. A cuspid occlusal upheaving splint or a stabilization splint was fabricated respectively for patients. The vertical dimension for each splint was 0.5 mm lower than mandibular postural position. Sleeping time, bruxist time and times of bruxism were recorded with bruxism monitor that was invented for studying bruxing.</p><p><b>RESULTS</b>The bruxist time and the times of bruxism were decreased obviously in patients with cuspid occlusal upheaving splint, while no significant difference was shown before and after using the stabilization splint.</p><p><b>CONCLUSIONS</b>The bruxism monitor can automatically measure and record the data of bruxism with splint, which is valuable for clinic. The curative effect of cuspid occlusal upheaving splint is better than that of stabilization splint for treating bruxism.</p>
