Background: Various implant impression techniques and materials have been proposed. Some clinical factors, such as the angulation or depth of implants, may affect the accuracy of the implant impressions. Lee et al. (Lee JPD 2008) reported that the splint-technique ensures a greater accuracy if compared to the non-splint technique, and, in case of 4 or more implants, the pick-up technique proves most appropriate. Polyether (PE) and VPS were the recommended materials for the implant impressions.
