OBJECTIVE To assess the survival percentage , clinical and radiographic outcomes of s and blasted and acid-etched ( SLA ) dental implants  and its modified surface ( SLActive ) in protocol s involving immediate and early occlusal loading .
A 5-year prospective multicenter study of early loaded titanium implants with a sandblasted and acid-etched surface.
PURPOSE For dental implants to be successful , osseointegration must occur , but it is unknown how much time must pass for osseointegration to be established . Pre clinical studies suggested that titanium implants with a s and blasted and acid-etched ( SLA ) surface were more osteoconductive and allowed more rapid osseointegration than machined or turned implant surfaces . The hypothesis of this study was that implants with an SLA surface could be loaded in half the conventional healing time of machined-surface implants and that , after loading , the implants would be successful for 5 years . MATERIAL S AND METHODS A prospect i ve multicenter clinical study was conducted with 439 implants placed in native bone in 135 edentulous and partially edentulous patients . Abutments were attached to the implant with 35 Ncm of torque without countertorque after 6 weeks in type I to III bone and after 12 weeks in type IV bone . The patients were carefully evaluated for 5 years . RESULTS Most implants were placed in nonsmoking , nondiabetic patients with a mean age of 55 years ( range , 21 to 82 years ) . Eighty percent of the implants were 10 or 12 mm long , 96 % had a diameter of 4.1 mm , and 78 % were placed in type II or III bone . Patients maintained good oral hygiene and were satisfied with the restorations . Four implants failed , and one implant was deemed unsuccessful between surgery and the 1-year postloading visit . No implants failed or were unsuccessful in subsequent years . The cumulative survival and success rates for 385 implants in 120 patients after 5 years were 99.1 % and 98.8 % , respectively . CONCLUSION Implants with an SLA surface can be restored in 6 weeks for type I to III bone and 12 weeks for type IV bone . Furthermore , they can be maintained after loading for 5 years with very high success and survival rates
