Statement of problem: How osseodensification osteotomy affects the implant stability and crestal bone level in patients requiring implant placement in low-density bone compared with conventional osteotomy is unclear.
Purpose: This systematic review and meta-analysis analyzed how implant stability and crestal bone level vary in a low-density bone in osseodensification osteotomy and conventional osteotomy.
Material and methods: The SCOPUS, PUBMED, and Google Scholar databases were searched, along with a manual search, for articles published between January 2013 and January 2024. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed to select the studies for review. A total of 5 studies were included in this systematic review. The Joanna Briggs Institute (JBI) tools were used to conduct the risk of assessment of the included articles, and forest plots were generated for the included articles (α=.05).
Results: The data were assimilated from a small sample size of 109 patients and 198 implants. The meta-analysis found that osseodensification resulted in significantly higher implant stability quotient (P<.05) values at baseline and follow-up, while the crestal bone level changes were not found to be significant (P>.05) at baseline or on follow-up visits.
Conclusions: The osseodensification drilling protocol displayed an advantage over the conventional drilling protocol regarding higher primary stability and secondary stability, as well as bone expansion in low-density bone. No significant difference in crestal bone loss was found in either technique at baseline or at follow-up.
