Accurate impression is essential factor for prosthesis fabrication. Various impression techniques
have been used to generate a definitive cast that will ensure the accurate clinical fit of implant
fixed complete dental prosthesis. Intraoral scanners can take implant impressions using light
beam without impression material or individual tray which were used by conventional technique.
Also, digital implant impression can eliminate the distortion of impression material, infection,
selection of tray and reduce the patients’ discomfort. Purpose of this study was taking the
efficient digital impressions through knowing the characteristic and principle of various intraoral
scanners.
At 1986, Mormannn et al. developed the CEREC (Chairside Economical Restoration of Esthetic
Ceramics, Sirona, Bensheim, Germany) system which was used to make inlay milling the feldspathic
porcelain at chairside and this was beginning of CAD/CAM (computer-aided design /
computer-aided manufacturing) instruments at dentistry.
There are many characteristic and limits of digital impression using intraoral scanner. Each
intraoral scanner has specific instructions and principles.
Obtaining digital impression using intraoral scanner with attention, it may express better result,
reduce the time and cost than conventional impression technique. And it is considered to deliver
satisfactory prosthesis to patients.
