Abstract
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.
