David laser scanner3/11/2024 The accuracy of measurements based on complex tooth fissures were equivalent for the 2 types of model. The laser-scanned models were more accurate than the plaster cast models in defining measurements based on simple tooth fissures. The measurements were repeated 10 times by the 2 observers with 1 week between each set of measurements. The same 5 measurements were performed on each of the 3D virtual surface models of the 14 plaster casts by 2 independent observers using Meshlab software in a manner similar to that used with the digital caliper. All 14 plaster casts were digitized using a low-cost DAVID SLS 3 laser scanner. The measurements were repeated 10 times on all 14 plaster casts by each observer, with a 1-week interval between each set of measurements. The aim of this study was to compare the accuracy of measurements taken from plaster casts (gold standard) with digital models of those casts created with a low-cost structural light DAVID laser scanner.įive different measurements were taken on each of 14 plaster casts by 2 independent observers with an electronic caliper. Accurate laser scanning of plaster casts using validated, low-cost hardware represents a key issue in 3D orthodontics.
