Intraoral Scanning Versus Alginate Impressions in Dental Students
Procedure Time and Patient Comfort of Intraoral Scanning Versus Alginate Impressions Among Dental Students: A Randomized Clinical Trial
Dental impressions are used to create a record of a person's teeth and oral structures. Conventional impressions are made using impression material placed in a tray, whereas digital impressions are obtained using an intraoral scanner.
This randomized clinical trial compared conventional alginate impressions with digital intraoral scanning using the TRIOS 3 and Medit i700 scanners among dental students aged 18 to 24 years. Participants were randomly assigned to one of the three impression techniques. Each participant underwent recording of both the upper and lower dental arches using the assigned technique.
The study primarily compared the chairside time required for each technique and the participants' experience immediately after the procedure. Comfort, nausea, breathing, pain, dry-mouth sensation, perceived procedure speed, overall satisfaction, and preference for conventional or digital impressions were also evaluated.

Aktivní komparátor: Conventional Alginate Impression
Participants underwent maxillary and mandibular conventional impressions using alginate impression material and stock trays according to the manufacturer's instructions.
|
Maxillary and mandibular conventional impressions were obtained using Tropical alginate impression material and stock trays.
The alginate was mixed, placed in the impression tray, and used according to the manufacturer's instructions.

Popis opatření |
Časové okno |
|---|---|---|
|
Total Chairside Procedure Time
Časové okno: During the assigned impression procedure at the single study visit
|
Total chairside procedure time was measured in seconds using a digital stopwatch and calculated as the sum of the recorded procedural stages.
For the conventional alginate group, the stages included maxillary mixing, maxillary impression taking, mandibular mixing, and mandibular impression taking.
For the digital groups, the stages included patient and case information entry, maxillary scanning, and mandibular scanning.
Bite-registration time was excluded from the total procedure time because there was no equivalent stage in the conventional alginate workflow.

During the assigned impression procedure at the single study visit
|
|
Patient-Reported Overall Comfort During the Impression Procedure
Časové okno: Immediately after completion of the assigned impression procedure
|
Overall comfort during the assigned impression procedure was assessed immediately after the procedure using a 0-to-100 visual analogue scale.
Higher scores indicated greater comfort.

Immediately after completion of the assigned impression procedure
