Resumen

HUAYTALLA ORE, Lizzeth Fiorella; MATTA MORALES, Carlos  y  DELGADO-COTRINA, Leyla. Position accuracy of short abutment analogs in the working model splinted with dental floss versus Bis-acryl bars in total edentulous mandibles. Rev. Estomatol. Herediana [online]. 2024, vol.34, n.2, pp.117-125.  Epub 29-Jun-2024. ISSN 1019-4355.  http://dx.doi.org/10.20453/reh.v34i2.5528.

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-Wilk, 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 show significant differences in the distance measurement; however, it did present differences in the height measurement, specifically between the FBA and SF groups, as well as between FBA and FHD groups.
