| Abstract | Palate depth is highly influenced by the genetic factor and differs significantly among the ethnic groups, but most of the impression tray manufacturers disregard it and produce stock trays with uniform depth. Thus, the impression becomes inappropriate and causes a massive loss of impression material. This study aims to measure the palate depths of a young Malay population and categorise them into different classes and determine the suitability of available stock trays by comparing impression material thickness. The palate depths of 123 maxillary dental arches were measured using Mitutoyo digimatic indicator and the Class interval was used for grouping the palate depths. The Duncan Multiple Range Test and Analysis of Variance were used for assessing differences among the groups. The range of depth of the stock trays was 3.32-8.99 mm in the canine region (DCC) and 10.18-20.80 mm in the first molar region (DM1M1) while for the casts these were 6.42-10.76 mm and 17.88-23.10 mm respectively. The palate depths of Malay dental arches can be grouped into three categories (shallow, moderate and deep palate) but the available stock trays were not adequate to accommodate these palates without any adjustments to the trays. |
