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 .
Early loading (2 or 6 weeks) of sandblasted and acid-etched (SLA) ITI implants in the posterior mandible. A 1-year randomized controlled clinical trial.
UNLABELLED The aim of this 1-year prospect i ve controlled clinical trial was to evaluate the effect of early loading of ITI solid screw titanium implants with a s and blasted and acid-etched ( SLA ) surface on clinical and radiographic parameters . MATERIAL AND METHODS Twenty-seven consecutively admitted patients presenting bilateral edentulous posterior m and ibular areas and in need of prosthetic reconstruction were recruited . Sixty-seven ITI st and ard solid screw implants with an SLA surface , a diameter of 4.1 mm and a length of 8 , 10 or 12 mm were installed bilaterally in molar and premolar areas according to a one-stage surgical protocol . One week ( test ) and 5 weeks ( control ) after implant placement , solid ITI prosthetic abutments were connected using a torque of 35 N cm . No provisional restoration was fabricated . Two weeks ( test ) and 6 weeks ( control ) after implant placement , porcelain-fused-to-metal single-tooth crowns were cemented . Clinical measurements were obtained at day 0 and 2 , 6 , 12 , 24 and 52 weeks thereafter . Periapical radiographs were taken immediately after implant placement , after 6 weeks and at the 1-year examination . RESULTS After 1 year , implant survival was 100 % . Two test and one control implants rotated at the time of abutment connection and were left unloaded for 12 additional weeks . At the 1-year examination , no statistically significant differences were found between the test and control sites with respect to pocket probing depths ( 2.6 mm + /- 0.5 vs. 2.7 mm + /- 0.5 ) , mean clinical attachment levels ( 3.1 mm + /- 0.4 vs. 3.2 mm + /- 0.5 ) , mean percentages of sites bleeding on probing ( 9.7 % vs. 8.3 % ) , mean widths of keratinized mucosa ( 1.8 mm + /- 0.4 vs. 1.9 mm + /- 0.5 ) , mean PerioTest values ( -1.4 PTV + /- 0.9 vs. -1.6 PTV + /- 0.8 ) or mean crestal bone loss measurements ( 0.57 mm + /- 0.49 vs. 0.72 mm + /- 0.50 ) . CONCLUSION Based on these results , loading of titanium implants with an SLA surface as early as 2 weeks did not appear to jeopardize the osseointegration healing process in the posterior m and ible . Furthermore , implants rotating at 35 N cm , if left unloaded for additional 12 weeks , did not negatively affect clinical and radiographic outcomes
