The aim of this systematic review was to assess the primary and secondary stability of dental implants placed at sites prepared with piezoelectric bone surgery (PBS) and conventional drilling (CD). The PubMed/MEDLINE and Cochrane Library databases were searched without date or language restriction up to June 2017. Controlled clinical trials in which each patient received implants placed at sites prepared with both PBS and CD were selected. Implant stability had to be measured on day 0 and during the osseointegration period. Methodological quality was assessed using the Cochrane Collaboration tool. A meta-analysis was performed to compare primary stability (on day 0) and secondary stability (after 2 and 3months) between the two groups. The studies included were determined to have a high risk of bias. There was no significant difference between the two groups for primary stability (on day 0) (P=0.51). After 2 and 3months, secondary stability was statistically higher in implants placed with PBS preparation (P=0.04 and P=0.01, respectively). The implant survival rate was 97.5% in the CD group and 100% in the PBS group. PBS preparation improves secondary stability after 2 and 3months in comparison to CD, with similar implant survival rates. Further studies are needed to determine whether implant osseointegration periods could be shortened with PBS preparation.
