Objective: This in vitro study introduced methods to measure the volume of sleep bruxism-like indentations to be used in the evaluation of bruxing intensity. Material and Methods: Indentations of different sizes and depths were created on seven clear heat-cured acrylic blocks. The volume of all indentations was first measured by a profilometer as the gold standard, then by scanning the negative replicate of the indentations obtained from polyvinyl siloxane impressions both with double impression technique (IOSD) and putty silicone only (IOSP), using an intraoral scanner, and lastly by weighing the blue inlay wax used to fill the indentation. Agreements between the intraoral scanning and blue inlay wax methods compared to the profilometer were tested using ICC. Results: ICCs between IOSD, IOSP, inlay wax and the profilometer were 0.963, 0.950, and 0.999 respectively. The average volumetric error tended to be greater with IOSD (30.51±8.34 %) and IOSP (35.68±10.29 %) compared to that of blue inlay wax (24.87±10.29 %). Blue inlay wax was apparently superior to IOSD and IOSP in quantifying small and deep indentations. Conclusion: Both intraoral scanner and blue inlay wax had high agreement in volumetric measurement of acrylic indentations while the wax method performed the best. These methods could be used to measure the amount of wear on occlusal splints.
