Description
Intraoral impression making is a basic technique in dental practice that is used to generate an imprint of the oral situation. Inaccurate impression may result in prosthesis misfit, which may lead to mechanical and/or biological complications. The current gold standard is the physical impression made with an elastomeric impression material. Recently, the advent of digital technology is developing expeditiously. Digital impressions have emerged as alternative to conventional impression technique and materials. The purpose of this in vivo study was to compare the accuracy of digital scanning and conventional techniques in partially edentulous dental impressions. Complete-arch impressions were obtained using two conventional (polyvinyl siloxane, PVS; direct scannable condensational silicone, S-CS) and one digital (3Shape Trios, TRI) techniques. The cast measurements were compared with intraoral measurements. No significant differences in trueness and precision were found between digital impression and conventional silicone impressions (p>0.05). Within the limitations of this
in vivo study, digital intraoral impression systems showed similar accuracy comparable to highly accurate conventional impression techniques. These techniques can also provide excellent clinical results within their indications and can be used as alternative to conventional impression techniques.
