This randomized controlled clinical trial compared osseodensification with manual bone expanders for implant placement in 18 patients missing a maxillary anterior tooth and with moderate horizontal ridge deficiency. Ridge width, bone density, and implant stability were assessed through 16 weeks. Both groups showed within-group increases in ridge width and bone density, with no significant between-group differences in ridge expansion or marginal bone loss. Osseodensification produced significantly higher secondary implant stability at 16 weeks than manual expanders, supporting its potential use for simultaneous ridge expansion and implant placement in this population.
Key findings
- Both groups had significant within-group increases in ridge width and bone density.
- There were no significant between-group differences in ridge expansion or marginal bone loss.
- Secondary implant stability at 16 weeks was significantly higher with osseodensification than with manual expanders.
Why it matters
Implant placement in a narrow anterior ridge requires adequate stability while preserving or increasing ridge dimensions. This trial suggests osseodensification can achieve ridge expansion comparable to manual expanders while providing higher secondary stability at 16 weeks. These findings may inform consideration of site-preparation options, although the small study population and limited follow-up constrain how broadly the results can be applied.
What to keep in mind
The trial included only 18 patients and assessed outcomes through 16 weeks, limiting the evidence on longer-term implant and esthetic outcomes.
