This may lead to high compression forces and elevated insertion torques. It has been postulated that disturbance of the local microcirculation may occur, leading to necrosis of the osteocytes and bone resorption.<\/jats:p><jats:p><jats:bold>Purpose:<\/jats:bold> Report on the clinical outcome of 42 implants placed with an insertion torque equal or greater than 70\u2003Ncm and evaluate bone levels around these implants.<\/jats:p><jats:p><jats:bold>Materials and Methods:<\/jats:bold> This prospective study included 48 patients treated with 66 4.5\u2003mm diameter Tapered Screw\u2010Vent implants (Zimmer Dental\u00ae, Carlsbad, CA, USA). Maximum insertion torque (MIT) was recorded with an electronic torque measuring device (Tohnichi\u00ae STC200CN, Hitachi, Tokyo, Japan).<\/jats:p><jats:p>Nine implants (control group) presented MIT between 30 and 50\u2003Ncm (mean\u2003=\u200337.1\u2003Ncm) and 42 implants (experimental group) MIT greater than 70\u2003Ncm (mean\u2003=\u2003110.6\u2003Ncm, range: 70.8\u2013176\u2003Ncm). Marginal bone levels were recorded at the time of loading and 1 year later for the two groups.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> After 2\u20133 months of non\u2010sumerged healing, all implants were clinically stable. Mean marginal bone resorption was 1.03\u2003mm (SD\u2003=\u20030.44) for the control group (low torque) and 0.72\u2003mm (SD\u2003=\u20030.56) for the experimental group (high torque) at time of loading, and 1.09 (SD\u2003=\u20030.62) and 1.24\u2003mm (SD\u2003=\u20030.75), respectively, after 1 year. There were no significant differences between the two groups for bone stability and implant success rate.<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> The use of high insertion torques (up to 176\u2003Ncm) did not prevent osseointegration. Marginal bone levels in the control and experimental groups were similar both at the time of loading and 1 year later.<\/jats:p>","DOI":"10.1111\/j.1708-8208.2011.00351.x","type":"journal-article","created":{"date-parts":[[2011,5,20]],"date-time":"2011-05-20T22:20:05Z","timestamp":1305930005000},"page":"227-233","source":"Crossref","is-referenced-by-count":53,"title":["Clinical
