PMID: 21519570

A survey demonstrated that angled abutments for external-hex implant platforms are difficult to place because of the handling of the components and screwdriver. The purpose of this study was to evaluate the performance of a device facilitating the placement of prefabricated angled abutments. This new instrument features improved ergonomics and is based on the design of a modified pickup impression coping. Forty experienced professionals tested two methods of placing angled abutments in a typodont on implants replacing a maxillary central incisor and a maxillary first molar. Using the new device, the abutments could be placed with a 43.9% reduction in time compared to the original manufacturer’s instrument. Int J Prosthodont 2011;24:238–240.
