Abstract

A wide choice of methods for obtaining impressions from a large number of installed dental implants leads to the question of the effectiveness and accuracy of existing methods. An accuracy assessment of the fit of the permanent prosthetic restorations based on parallel-installed dental implants was carried out after receiving the impressions with a standard closed tray, an individual open tray without splinting impression copings, splinting impression copings over and under the open tray. The accuracy of the transfer of the dental implants position was estimated by the size of the gap that occurs when fitting a permanent restoration. The smallest gap, (0,241 ± 0,06) mm, was detected using an open tray with splinting impression copings under the tray. It provides the most accurate result of the transfer of the dental implants position installed in parallel in comparison with other methods of obtaining impressions.
