Objective To assess the survival percentage, clinical and radiographic outcomes of sandblasted and acid‐etched ( SLA ) dental implants and its modified surface ( SLA ctive) in protocols involving immediate and early occlusal loading. Methods MEDLINE , EMBASE and the Cochrane Oral Health Group's Trials Register CENTRAL were searched in duplicate up to, and including, June 2013 to include randomised controlled trials ( RCT s) and prospective observational studies of at least 6‐month duration published in all languages. Studies limited to patients treated with SLA and/or SLA ctive implants involving a treatment protocol describing immediate and early loading of these implants were eligible for inclusion. Data on clinical and/or radiographic outcomes following implant placement were considered for inclusion. Results Of the 447 potentially eligible publications identified by the search strategy, seven RCT s comprising a total of 853 implants (8% titanium plasma‐sprayed, 41.5% SLA and 50.5% SLA ctive) and 12 prospective observational studies including 1394 SLA and 145 SLA ctive implants were included in this review. According to the Cochrane Collaboration's tool for assessing risk of bias, one of the studies was considered to be at a low risk of bias, whereas the remaining studies were considered to be at an unclear risk. Regarding the observational studies, all of them presented a medium methodological quality based on the Modified N ewcastle– O ttawa scale. There were no significant differences reported in the studies in relation to implant loss or clinical parameters between the immediate/early loading and delayed loading protocols. Overall, 95% of SLA and 97% of SLA ctive implants still survive at the end of follow‐up. Conclusions Despite of the positive findings achieved by the included studies, few RCT s were available for analysis for SLA ctive implants. Study heterogeneity, scarcity of data and the lack of pooled estimates represent a limitation between studies' comparisons and should be considered when interpreting the present findings.
