Abstract
The purpose of this study was to systemically analyse the effects of photobiomodulation
therapy (PBMT) on implant stability and postoperative recovery. Electronic searches
on MEDLINE (PubMed), Cochrane Library, EMBASE, and Web of Science were completed independently
by two researchers in February 2021, and a manual search was performed for the references
of the included articles. The primary outcome was implant stability. The secondary
outcome was postoperative recovery, including postoperative pain, recovery of peri-implant
hard tissue (marginal bone loss and bone mineral density), facial swelling, and peri-implant
clinical parameters. Twenty studies were finally obtained (17 randomised controlled,
and 3 controlled clinical studies). Meta-analysis revealed that PBMT increased implant
stability at 10 days after insertion (MD 2.27, 95% CI: 0.40 to 4.13, P = 0.020), and reduced marginal bone loss at 6 months after insertion (MD −0.16, 95%
CI: −0.23 to −0.08, P < 0.001). However, no significant improvements were noted in implant stability two
weeks (P = 0.070), three weeks (P = 0.090), six weeks (P = 0.050), and 12 weeks (P = 0.080) after insertion. Qualitative analysis suggested that PBMT could not alleviate
postoperative pain, increase bone mineral density, or improve peri-implant clinical
parameters. It was effective only in reducing facial swelling. This study suggests
that the effects of PBMT on implant stability and postoperative recovery may be limited.
