عنوان انگلیسی Comparative investigation of primary stability of four different dental implants in low‑density bone model
چکیده انگلیسی مقاله Background: Primary stability is one of the prerequisites of immediate loading. The aim of this study was to compare the primary stability of four different implant systems in low‑density bone models. Materials and Methods: In this in vitro experimental study, 20 fixtures from four implant body designs were selected: Zimmer Tapered Screw‑Vent (ZTSV), NobleReplace Tapered (NRT), Replace Select Tapered (RST), and Dentium SuperLine (DSL). Fixtures were inserted in low‑density bone models according to manufacturer drilling protocol by one surgeon. Measurement of insertion torque value (ITV), resonance frequency analysis (implant stability quotient [ISQ]), and reverse torque value (RTV) was recorded for each fixture. The data were analyzed with one‑way ANOVA and post hoc tests (Tukey honestly significant difference) ( P < 0.05). Results: ZTSV had significantly lower amount of insertion torque in comparison to other systems ( P = 0.045). RTV was significantly lower in ZTSV in comparison to DSL and NRT ( P = 0.004). ISQ value in NRT (ISQ = 67) was significantly higher than other systems ( P = 0.000). The lowest amount of ISQ was in RST system (ISQ = 53) with significant difference ( P = 0.000). Conclusion: This study demonstrated that primary stability of different implant systems was not comparable and implant design was effective on ITV, RTV, and ISQ. Key Words: Dental implants, immediate dental implant loading, resonance frequency analysis, torque
