Osseodensification vs Conventional Drilling Technique, Clinical Comparative Study

Background Osseodensification (OD) is a non-extraction implant site drilling concept developed by Salah Huwais in 2013, it utilizes a multi-step drilling process that allows autograft compaction along the implant site wall and bone preservation.The autograft›s compaction and residual bone shards› presence increase the autograft›s stability.Objectives To assess the effect of the drilling procedure on implant stability changes by using the OD drilling technique and compare it with that of the conventional technique.Materials and Methods This case-control observational study included nine patients who received a total of 18 dental implants (DI) for both groups, each patient received two implants (one for the study group and the other one for the control group) inserted in the same jaw either adjacent or bilaterally in the same location.DIs were installed after the preparation of the implant site using either the OD technique (study group) or the conventional technique (control group).Preoperatively, Cone-beam computed tomography (CBCT) was used to assess the alveolar bone dimensions and to make sure that bone density was less than 850 Hounsfield units (HU), corresponding to D3-D5 of Misch bone density classification.The primary and secondary implant stability was assessed using the Osstell Mentor device (Goteborg, Sweden) and was recorded as an implant stability quotient (ISQ).Results Regarding the primary stability, there was a statistically non-significant difference between the two groups (P-value 0.932), while for the secondary stability, the control group demonstrated significantly higher ISQ values than the study group (P-values 0.022).Conclusion The OD technique did not indicate a more positive result in terms of implant stability than the conventional one.
