Abstrakt:	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.
