Bottom Line: In total, 36 patients (21 men and 15 women) were selected and a retrospective medical record review was performed.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.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.

ABSTRACT

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.

Graphs present the percentage BOP (a) and PPD (b) in the two groups during the follow-up period. Within 2 years postoperatively (T3), there is no significant difference in BOP and PPD between the two groups. However, the intraoral jaw bone graft group (Group 2) has a significantly lower percentage of BOP and PPD than the iliac bone graft group (Group 1) at T4 (2–3 years postoperatively) and T5 (>3 years postoperatively). Different letters denote statistical differences between groups (p < 0.05)

Mentions: The mean ISQ value was 69 ± 9 in Group 1 and 71 ± 10 in Group 2; there was no statistical difference between the two groups (Fig. 6f). During the follow-up period (T3–T5), the percentage of BOP and PPD was measured for each implant site. Within 2 years post-operatively (T3), there was no significant difference in BOP and PPD between the two groups. However, the jaw bone graft group (Group 2) had a significantly lower percentage of BOP and PPD than the iliac bone graft group (Group 1) at T4 (2–3 years postoperatively) and T5 (more than 3 years postoperatively) (p < 0.05). These results indicate that intraoral jaw bone grafts could provide stronger resistance against peri-implantitis than iliac bone grafts (Fig. 7).Fig. 7
