Despite of the positive findings achieved by the included studies , few RCTs were available for analysis for SLActive implants .
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 .
Three-year data from a randomizd, controlled study of early loading of single-stage dental implants supporting maxillary full-arch prostheses.
PURPOSE The aim of this 3-year r and omized controlled trial ( RCT ) was to compare biologic and technical treatment outcomes and patient satisfaction after early ( < or = 14 days postimplantation ) loaded implants with those of implants loaded after a healing period of 3 to 4 months in the edentulous maxilla . MATERIAL S AND METHODS Twenty-four patients with completely edentulous maxillae were r and omized into a test group ( n = 16 ) and a control group ( n = 8) . All patients received 5 or 6 solid screw-type titanium implants with s and blasted , large-grit , acid-etched ( SLA ) surfaces . In total , 142 implants were placed and 139 implants were loaded with full-arch prostheses  . Clinical assessment s were obtained at loading and after 3 , 6 , 12 , 24 , and 36 months . Radiographs of implants and existing teeth were taken at loading ; after 6 , 12 , 24 , and 36 months ; and at 12 , 24 , and 36 months , respectively . RESULTS The cumulative implant success rate 3 years after loading was 100 % . At the 3-year examination the mean ( P < or = .005 ) , distal ( P < or = .005 ) , and mesial ( P > .05 ) crestal bone levels were better in the test group . No significant differences between the test and control groups were noted for any other outcome measure . The most common adverse event in both groups was tooth-crown fracture . DISCUSSION A review of the literature , both printed and electronic , revealed no study fulfilling the criteria of an RCT dealing with the early loading of maxillary full-arch prostheses . This study fulfills those criteria . CONCLUSION In this study population it has been concluded that the early ( approximately 2 weeks ) loading protocol is a viable alternative to the st and ard ( 3 to 4 months ) protocol in the rehabilitation of a completely edentulous maxilla with a complete implant-supported fixed prosthesis
