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.

Comparison of the changes in increased bone height after bone graft (a-d), analysis of radiological intensity (HU values) in the newly generated bone using CT views at T3 (e), and implant stability quotients (ISQ values) by resonance frequency analysis results at T2 (f). a & b In both inlay and onlay type bone grafts, Group 1 shows a more prompt vertical bone loss than Group 2; there is statistical difference in remaining bone height between the two groups at T4 and T5. The intraoral jaw bone graft group has more residual grafted bone height than the iliac bone graft group after 2–3 years postoperatively (p < 0.05). c & d Changes in the vertical bone height were compared in the maxillary and mandibular ridges. In the maxillary fixtures, the intraoral jaw bone graft group showed a statistically lower vertical bone resorption rate at T4 and T5 than the iliac bone graft group (p < 0.05). A similar tendency for vertical bone resorption was observed in the mandibular fixtures, with no statistical difference between the groups (p > 0.05). e CT views at T3 (1 year postoperatively) reveal similar HU values in the newly generated bones between the two groups (p > 0.05). f Implant stability tests by resonance frequency analysis at T2 (5–6 months postoperatively) exhibit similar ISQ values between the two groups (p > 0.05).

Mentions: The implant stability quotients (ISQ) were measured by Osstell™ Mentor (Osstell, Gothenburg, Sweden) during the second implant surgery procedure at 5 to 6 months after fixture placement (T2) (Fig. 6). The ISQ was measured at least three times for each fixture, and was represented as the mean ± standard deviation (SD) of both the subantral inlay-type and the onlay-type bone graft groups. For all fixtures, the incidence of peri-implantitis was analyzed by probing pocket depth (PPD) and bleeding on probing (BOP) during the annual follow-up periods (T3 ~ T5). The data were digitalized and statistically evaluated between the two groups.

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.
