Implant with an axial orientation that is not in line with the needs of prosthetic rehabilitation may occur for various reasons. As a result, the impression procedure may be adversely influenced. Inaccuracies during impressions inevitably lead to laboratory errors resulting in lack of precision and misfit of the restoration. The accuracy of the implant cast depends on many factors; the type of impression material, implant impression technique, the implant angulation, the die material accuracy, and the master cast. All these techniques and factors were introduced and investigated for accuracy, but results were not always consistent. The purposes of the present review were to investigate 1) The scientific data related to different aspects of angulated implant impression accuracy and 2) To examine the clinical factors affecting the implant impression accuracy.
