COMPARING THE EFFICACY OF OSSEODENSIFICATION OVER CONVENTIONAL DRILLING TECHNIQUE ON IMPLANT STABILITY AND BONE DENSITY IN LOW BONE DENSITY SITES: A SYSTEMATIC REVIEW AND META-ANALYSIS

Abstract

Purpose of the research

To assess the efficacy of osseodensification (OD) over conventional drilling technique (CD) on implant stability and bone density in low bone density sites.

Materials and methods

An electronic and manual search were conducted to analyze the effect of OD over CD technique on implant stability and bone density in human-based randomized controlled trials (RCTs) and nonrandomized controlled trials (NRCTs). The risk of bias was assessed using (RoB 2.0) and (ROBINS-I) tools for RCTs and NRCTs respectively. The meta-analysis was applied with RevMan 5.4, using the random-fixed effects model. Heterogeneity was assessed by a Q test and quantified with I² statistics.

Results

Our literature search identified 1454 publications, of which only 6 met all the inclusion criteria. The meta-analysis of the included studies showed that the implant stability quotient (ISQ) was greater in OD than in the CD group without being statistically significant both immediately and at the follow-up period after implant placement, with a standardized mean difference of 2.13 [95%CI = −0.08, 4.35] with P = .06 and 1.81 [95%CI = −0.41, 4.03] with P = .11 respectively. The difference in bone density in the OD compared to the CD group was statistically significant, immediately after implant placement with a standardized mean difference of 2.14 [95%CI = 0.68, 3.59] with P = .004 and nonsignificant at 3 to 7 months with a standardized mean difference of 1.54 [95%CI = −0.34, 3.43] with P = .11.

Conclusion

The findings of the present review and meta-analysis show that dental implants placed using the OD technique reveal greater implant stability and improved bone density in areas with low bone density compared to the CD technique. However, more clinical studies are needed to validate the findings.
