Background: Jaw bone and iliac bone
are the most frequently used autologous bone sources for dental implant
placement in patients with atrophic alveolar ridges. However, the comparative
long-term stability of these two autologous bone grafts have not yet been
investigated. The aim of this study was to compare the stability of
simultaneously placed dental implants with autologous bone grafts harvested from
either the iliac crest or the intraoral jaw bone for
severely atrophic alveolar ridges.
Methods: In total, 36
patients (21 men and 15 women) were selected and a retrospective medical record
review was performed. We compared the residual increased bone height of the
grafted bone, peri-implantitis incidence, radiological density in newly
generated bones (HU values), and implant stability using resonance frequency
analysis (ISQ values) between the two autologous bone graft groups.
Results: Both autologous bone
graft groups (iliac bone and jaw bone) showed favorable clinical results, with similar long-term implant
stability and overall implant survival rates. However, the grafted iliac bone
exhibited more prompt vertical loss than the jaw bone, in particular, the
largest vertical bone reduction was observed within 6 months after the bone
graft. In contrast, the jaw bone graft group exhibited a slower vertical bone
resorption rate and a lower incidence of peri-implantitis during long-term
follow-up than the iliac bone graft group.
Conclusions: These findings demonstrate that
simultaneous dental implantation with the autologous intraoral jaw bone graft
method may be reliable for the reconstruction of edentulous atrophic alveolar
ridges.
