The number of subjects who responded that digital impression taking was easier than conventional impression taking as an operator was greater for rubber impression materials than for alginate.
The treatment time was measured in seconds and recorded for each step by a second operator (R.T. & H.B .. Immediately after the impressions were made, the attitudes and perceptions of the subjects towards the conventional impression technique were evaluated using a standardized questionnaire.
3. The treatment comfort of the digital impression technique was higher than that of the conventional impression technique when it was performed by an experienced operator.
The effectiveness and clinical outcomes of the conventional impression technique was evaluated by measuring the total treatment time, including the individual steps: A) tray selection, B) adhesive application, C) upper/lower impression, D) bite registration.
Digital impression systems have been developed to overcome the disadvantages associated with conventional impression methods.
Vasudavan et al. [27] compared intraoral scanning and conventional impression techniques for fabrication of orthodontic retainers.
Conventional impression materials and techniques have been used successfully to fabricate fixed restorations.
With the continued development of digital impression technology, we will likely see the elimination of conventional impression taking in the near future.
