Objective: To compare in vitro the positional accuracy of short abutment analogs splinted with dental floss versus short abutment analogs splinted with Bis-Acryl bars as a preliminary step to obtaining the working model in the preparation of implant-supported prostheses in total edentulous mandibles. Materials and methods: An aluminum master model simulating an edentulous mandible with five analogues was prepared. Using a customized tray and by means of a technique for fixing the transfers to it, thirty impressions were recorded, which were divided into three groups: SF group (without splinting), FHD group (splinting with dental floss) and FBA group (splinting with Bis-Acryl bars). Subsequently, a digital indoor micrometer was used to perform distance and height measurements between analogs. The statistical tests used were Shapiro Wilks, ANOVA and Tukey's post hoc. Results: For distance measurements, no statistically significant differences were found between groups (p = 0.674). For height, statistically significant differences were found between groups (p < 0.001). Bis-Acryl presented differences with the SF and FHD groups (p < 0.001). Conclusions: Splinting of short abutment analogs did not present significant differences in the distance measurement; however, it did present differences in the height measurement, specifically between the FBA group with the SF and FHD groups.
