A prospective study evaluating a protocol for 6 weeks' loading of SLA implants in the posterior maxilla: one year results.
Experimental and clinical studies have shown that modification of implant surfaces can result in increased bone-to-implant contact at earlier times thus reducing the healing period between surgery and prosthesis . S and blasted and acid-etched ( SLA ) implants are in this category and have successfully undergone early loading in patients with good bone quality and quantity . Nevertheless , premature loading of SLA implants was not routinely possible in predominantly trabecular bone , such as the posterior maxilla , as it is often characterized by a deficiency in initial bone to implant contact . The purpose of this prospect i ve clinical investigation is to evaluate the efficacy of a modified surgical protocol followed by loading SLA implants at 6 weeks in the posterior maxilla . Drilling was limited to the minimum , and most of the site preparation was produced with osteotomes . Screw tapping was never performed and primary stability was always achieved . Abutment connection was carried out at 15 Ncm 43 ( + /- 1 ) days after surgery and provisional restoration was fabricated . Further abutment tightening at 35 Ncm was performed after an additional 6 weeks . Of the 36 SLA implants placed in 19 patients , one was lost before final restoration .  Clinical and radiographic measures were taken at baseline and 1 year postoperatively . The preliminary results suggest that , by means of the surgical and restorative technique presented , SLA implants are suitable for loading at 6 weeks in the posterior maxilla . More years of observation will verify whether osseointegration can be equally maintained over a long period
