The aim of this study was to evaluat the influence of insertion torque on the survival of immediately placed single tooth implants and bone resorption process around it . Materials and methods : 8 healthy patients received 24 conical implants ( ID
I-BIO ) with sand blasted and acid etched surface . All implants inserted immediately in extraction sites, the sample were divided into two groups: The implants in the first group were inserted with insertion torque below 35 Ncm (mean 25 Ncm ) , while in the second group the implant were inserted with insertion torque above 35 Ncm (mean 52,2) .Implant survival and marginal bone loss MBL were evaluated after two , six and nine months for both groups .Results : four implants from the first group failed to osseointegrate, and statistical analysis of the data showed no correlation between insertion torque and peri- implant bone resorption .
