    Background: Primary stability (PS) is dependent on the length and diameter of the implant, micro-morphology of the implant surface, implant design, surgical procedure, bone quantity, and quality. This study aimed to compare short and standard dental implants according to primary stability in bone type IV using Resonance frequency analysis (RFA) test equipment. Methods: Seventy two dental implants; sandblasting with large grit particles and acid etching (SLA) surface (Dentium®,SimpleLine II, Seoul, Korea), SLActive surface- (Straumann Roxolid®, Basel, Switzerland), Resorbable blast media (RBM) surface- (Implance®, Trabzon, Turkey) with very short (4-mm length), short (6-mm length) and standard dental implants (10-mm length) were placed in bovine cow ribs with bone quality similar to a type IV human bone. RFA was performed to evaluate the primary stability. One-way ANOVA test was used to compare the groups ve different groups were assessed with the post hoc Tukey test. Results: Implant stability quotient (ISQ) measurements of 4-mm and 6-mm length implants were similar however, 10-mm-length implants showed statistically difference inter-groups. SLActive surface in 10-mm-length implant group showed highest ISQ value (p<0.005). When primary stability was compared in intra groups, SLA surface and RBM surface implants showed no significant difference, but 10-mm-length of SLActive surface implant showed higher ISQ value than 4-and 6-mm length (p<0.005). Conclusion: Implant design and surface characteristics might be also effective in primary stability in very short and short implants and SLActive surface implants may show better primary stability in standard implants.
