Abstract
Objective: To compare the experience curves between two intraoral scanners (Trios® and Medit®) among undergraduate dental students (Fifth and sixth year) and to determine whether iterated scanning could affect scan time.
Method: Twenty-four undergraduate dental students were recruited in this study, the dental students were allocated into two groups, Medit® and Trios®. Each subject was required to scan according to this sequence: one time in dentoform, ten times in patient, one time in dentoform. The scan time and actual time were recorded in two terms namely the actual time and scan time. Actual time refers to time since the begining until the end of scanning session. The scan time represents the time that was shown in the software.
Result: The average of the actual time of twelve sessions was greater with Medit® than Trios®, but a greater decrease in average of actual time was observed in Medit®. Unlike the learning rate of Medit®, Trios® was influenced by patient factor.
Conclusion: The learning rate for Medit® was faster whereas the average actual time of Medit® was greater than Trios®. There was slightly difference between experience curve of Medit® and Trios®.

What was the patient factor that influenced the learning rate?
Comparing between these two scanners, which one was perferable in term of actual time and scan time?
1.Do you think, the different of examinor between fifth year or sixth year student affecting result in the actual time?
2, You comparision of scaner time between teeth in dentoform and teeth in patient oral cavity. It's different of structure. So, What was you scanned the teeth in phantom head or only dentoform?
Regarding to ทญ สุปราณี เบ็ญจสุพัฒนนันท์ questions,
1. What was the patient factor that influenced the learning rate?
- Patient factors: such as the maximum mouth opening width, number of teeth, the tongue movement, salivary flow could possibly affect the complexity of scanning, however, most related studies have shown no relationship between these factor and scanning time. Even so, we had tried to minimize these variations by setting patient criteria to within normal range, for instance, the patient must have at least 38mm for maximum mouth opening width.
2. Comparing between these two scanners, which one was preferable in term of actual time and scan time?
- From our data collection, Trios® had performed faster scanning time in both actual time and scan time than Medit®. However, no significant difference was found.
Regarding to Dr.Rutapakon Insawak's questions,
1. Do you think, the different of examiner between fifth year or sixth year student affecting result in the actual time?
- We think that there might be some difference as fifth year student has less clinical experience, which may result in longer scanning time. Surprisingly, there was no significant difference between the fifth and the sixth-year dental students.
2. You comparision of scanning time between teeth in dentoform and teeth in patient oral cavity. It's different of structure. So, What was you scanned the teeth in phantom head or only dentoform?
- Regarding to reduce the variation of patients which could affect the scanning time, our study had designed to confirm the result by scanning the dentoform in the phantom head in the first and the last session of scanning. In addition, the operators could gain their experience on intraoral scanner before performing in the real patient.
