RESUMEN

AIM: This investigation aimed to evaluate the 1-year survival of implants placed after staged lateral alveolar ridge augmentation using equine-derived collagenated xenogeneic bone blocks (CXBBs) or autogenous bone block (ABB). MATERIALS AND METHODS: Fifty patients who underwent lateral augmentation in a previous trial were included. The primary outcome measure was implant survival at the 1-year follow-up, and secondary outcomes included implant success, peri-implant clinical and volumetric parameters, pink aesthetic scores (PES) and patient-reported outcome measures. Data analysis involved Fisher's exact test, the Mann-Whitney U-test and the Wilcoxon signed-rank test. RESULTS: In this study, no late implant failures were observed. The cumulative survival rates were 78.6% for the CXBB group and 90.9% for the ABB group, with no difference between the groups. Similarly, the success rates were 53.6% and 63.6%, respectively, showing no significant difference. Peri-implant clinical and volumetric parameters indicated the presence of healthy peri-implant tissues surrounding implants placed in both CXBB- and ABB-augmented sites. PES were 8.5 and 11.0 for implants placed in CXBB- and ABB-augmented sites, respectively. Furthermore, patient satisfaction rates were high and similar between the groups. CONCLUSIONS: Dental implants placed in both CXBB- and ABB-augmented ridges demonstrated no statistically significant differences in clinical, volumetric and aesthetic outcomes, along with high patient satisfaction rates.

RESUMEN

Recombinant human bone morphogenetic protein-type 2 (rhBMP-2) is used in oral and maxillofacial procedures due to its endochondral bone formation capacity, and this is also the reason for its use off-label in jaw reconstruction. This study reports a case of an extensive central giant cell lesion along the mandibular body and symphysis. Treatment consisted of enucleation and curettage followed by off-label use of rhBMP-2 associated with bovine bone xenograft. The literature concerning mandibular reconstruction using rhBMP-2 was also reviewed.
