<![CDATA[Purpose: For successful osseointegration of an immediately loaded implant, the fundamental element isprimary stability. Establishment of primary stability is influenced by combination of various factors one ofthem being implant geometry. Evaluation of primary stability and the factors influencing it is essential forsuccessful treatment outcome.Methods: A total of 20 patients were divided into two groups. the implant placed in group I was with squarethread designs (Ankylos® implant ,DENTSPLY, Sirona) and group 2 was V shaped thread design MIS sevenimplant( MIS implant Ltd, Israel) in the pre molar-molar region. The stability was assessed with the aid ofresonance frequency analysis (Osstell™, Integration Diagnostics, Sweden) at the time of implant placement,at three months and at six months. A repeated measure ANOVA and Bonferroni Pairwise comparison wasused to compare the ISQ within each group.Results:There was a statistically significant difference in the stability at baseline to six months (p=0.006),from baseline to three months (p=0.006) and from three months to six months (p<0.001) in both the groups.Correlation could be found between implant geometry and stability observing improved stability in group 1compared to group 2.Conclusion: The result from this material showed that the all implants were successfully osseointegratedwith a mean ISQ of 80 and 71 at six months in group I and group II respectively. Implants with square threadsshowed a higher stability at baseline, at three months and at six months in comparison to the v shaped thread.]]>
