Résumé
Implant stability is one of the main indicators of successful osseointegration. Although
it has been measured in numerous studies, there has been little research on implant stability in
regenerated bone. The study compares primary and secondary stability between implants placed
in regenerated versus native bone and evaluates the influence of bone quality on the results. Sixty
implants were placed in 31 patients: 30 implants inserted in native bone (non-regenerated) after a
healing period of at least 6 months post-exodontia and 30 inserted in regenerated bone at 6 months
after grafting with xenograft. Resonance frequency analysis (RFA) was used to obtain implant
stability quotient (ISQ) values at baseline (implant placement), 8 weeks, and 12 weeks. Statistically
significant differences were found between implants placed in regenerated bone and those placed in
native bone at all measurement time points (p < 0.05). ISQ values were significantly influenced by
bone quality at baseline (p < 0.05) but not at 8 or 12 weeks. Greater stability was obtained in implants
placed in native bone; however, those placed in regenerated bone showed adequate primary and
secondary stability for prosthetic loading. Bone quality influences the primary but not secondary
stability of the implants in both native and regenerated bone.
