Maxillary osteotomy complications in piezoelectric surgery compared to conventional surgical techniques: a systematic review

A systematic review was conducted to investigate the available evidence on maxillary complications related to piezoelectric and conventional surgery. Seven databases were searched. A total of 996 maxillary osteotomies were analysed, 864 performed with conventional tools and 132 with a piezoelectric device. One hundred and fifty-six complication events were reported. The complications, in descending order of overall prevalence, were as follows: neurosensory disturbance (64.7%), haemorrhage (8.3%), oroantral communication (7.7%), soft tissue injury (7.7%), tooth injury (5.1%), infection (3.2%), osteonecrosis (1.9%), and permanent nerve injury (1.3%).
