Accuracy Comparison of Implant Impression Techniques: A Systematic Review

“…Nevertheless, the registered average of 35 μm in vertical displacement seemed precise enough for single crowns, short‐span, implant‐supported fixed partial prostheses . The encode system was found to be less accurate when compared with direct and indirect technique in the parallel implant group …”

“…Ten studies evaluate different coping types . From these, seven studies advocate the open technique with square copings as the most accurate, and three studies report similar results between copings .…”

“…From the 14 studies, none advocated the indirect (closed) technique. Although six of these studies reported similar results between both techniques, other sources of inaccuracy were identified other than the impression technique, such as angulation or coping shape …”

“…Howell and colleagues and Eliasson and Ortorp evaluated and compared the accuracy of similar implant placements in working casts using impressions of digitally coded healing abutments. The encode technology presented higher accuracy levels of mean center point displacement compared with the conventional technique.…”

Limiting the dimension of a screw-access hole with an interim screw-retained prosthesis

“…The implant site is indexed to the adjacent hard and soft tissue, either with a conventional implant impression, a digital scan, or a transfer coping. [7][8][9] The technician can design the interim prostheses on the working cast with a variety of materials and methods. A common procedure is to first fabricate a diagnostic waxing as the basis for the prostheses.…”
