Optical impressions of implants in the edentulous arch are challenged by absence distinct surface morphology between multiple implant scan bodies. The purpose this vitro study was to evaluate a newly developed aid various designs and colors improve accuracy multi-implant scans.A universal three different (circular, square, irregular) materials (colors: beige, gray, white) applied bodies master model six an maxilla. Ten scans using intra-oral scanner each were acquired. Reference scanning performed desktop optical scanner. Alignment at first body three-dimensional modeling inspection software deviations for trueness precision calculated signed nearest-neighbor method then statistically analyzed (α = .05).Overall, beige irregular had highest showed significant differences compared unsplinted scans. more heterogenous results decreased when aid. Ease use observed with gray due its increased elongation break.The evaluated led improved Even though design color trueness, poor fracture strength tested material requires further improvement.
