| Summary: | Moritz Waldecker, Dr Med Dent/Charlotte Trebing, Dr Med Dent/Stefan Rues, Dipl-Ing/Rouven Behnisch, MSc/Peter Rammelsberg, Prof Dr Med Dent/Wolfgang Bömicke, PD Dr Med Dent, MSc: Purpose: To investigate the effect of training on scanning times of complete-arch scans (CAS) performed - by first-time users, with a distinction made between specific training (repeated practice of CAS) and - nonspecific training (simple use of an intraoral scanner for a sextant scan in the context of a student CAD/CAM course). Methods: Thirty-six students with no experience in intraoral scanning were randomized into - three groups (n = 12 per group) according to the number of specific CAS training sessions: three sessions (3S), - two sessions (2S), and one session (1S). Each student performed 10 CAS per scanning session. These sessions - were scheduled at baseline (T<sub>0</sub>), T<sub>1</sub> (2 weeks after T<sub>0</sub>), and T<sub>2</sub> (4 weeks after T<sub>0</sub>) for group 3S; at T<sub>0</sub> and T<sub>2</sub> for - group 2S; and at T<sub>2</sub> for group 1S. Before the final scanning session in each group (ie, the first scanning session - in group 1S), the students participated in a CAD/CAM course (3 weeks after T0) in which a monolithic crown - was fabricated in a fully digital chairside workflow. The scanning time was measured as the time between - the activation and termination of the scanning mode of the intraoral device. Data were analyzed using SPSS - Statistics 25 (IBM). The level of significance was set to α = .05. Results: A continual decrease in scanning time - was observed for all groups as experience in intraoral scanning increased. The mean scanning times were - as follows: for group 3S, 305 seconds at T<sub>0</sub>, 246 seconds at T<sub>1</sub>, and 233 seconds at T<sub>2</sub>; for group 2S, 380 - seconds at T<sub>0</sub> and 303 seconds at T<sub>2</sub>; and for group 1S, 355 seconds at T<sub>2</sub>. When compared to group 1S after - it had received nonspecific training only, the effect of a single specific training session in groups 3S and 2S - was not significant (P = .4428). However, two specific training sessions had a significant effect on scanning - time compared to nonspecific training only (P = .0005). Conclusion: Training does affect the scanning time - required for CAS. To perform such scans in a time-efficient manner, dental practitioners should undertake - training that comprises at least 12 CAS. |
