Analysis of accuracy of two different implant impression techniques

Background: Comparatively evaluate the accuracy of two different implant impression techniques. Materials & methods: For present study, reference models used were an edentulous mandibular cast with four analogues in anterior region and a metallic insert posterior. Two techniques studied as followed: Group 1: Polyvinyl siloxane impressions (putty light body) using stock metal tray, 2: Polyether (medium tray. Connection posts was done to screws tightened manually such that their flat surfaces facing buccally. The longer connected shorter posterior analogues. A self-calibration test performed determine obtained by single evaluator. Results: Mean error among specimens 1 0.0441 while mean 2 0.0425 respectively. While comparing study groups, non-significant results obtained. Conclusion: From above results, authors concluded both can be equal effectiveness procedures.
