Abstract

Background and Aims: Taking IMPRESSION from angulated implants has always been a great challenge in clinic. In this regard, studies on sectional trays are very few. The aim of this study was to evaluate and compare the dimensional and angular accuracy of IMPRESSIONs using full arch and sectional trays.Materials and Methods: Four implants (4.3×12 mm) (Implantium, Dentium) were placed in the first premolar and molar regions of a Kennedy class I mandibular acrylic model with 30° lingual angulation. Twenty open special trays (Full arch & Sectional) were made on the primary cast. The IMPRESSIONs were taken using VINYL POLYSILOXANE (VPS) and were poured with type IV dental stone. The coordinate measuring machine (CMM) was used to measure the dimensional (Z, Y, X) and angular (q) coordinates of implants. The data were analyzed using and t-test and SPSS 22. Software.Results: The type of tray had no significant effect on the dimensional accuracy in X, Y and Z axes (P>0.05) and total linear displacement (r); However, it significantly affected the angular accuracy (Dq) (P<0.05).Conclusion: Sectional tray yields less rotational displacement in IMPRESSIONs made of angulated implants.
