This study aims to analyze three\u2010dimensional bone gain, assess marginal bone stability in such defect configurations, and evaluate the impact of grafting outside the bone contour on the overall outcome, with a focus on iliac crest block grafts as a valid treatment option.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>The prospective cohort study evaluated patients who required vertical block grafting due to localized bone defects in the maxilla or mandible and who had received iliac grafts. Three\u2010dimensional bone gain was analyzed using cone beam computed tomography (CBCT) after 3\u2009months of bone healing for each treated site and implant position. A comparison between bone grafts inside and outside the bone contour was conducted. Marginal bone stability was measured using intraoral radiographs during routine annual follow\u2010up visits.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Seventy patients with 89 treated sites were evaluated. After 3\u2009months of graft healing, the mean vertical bone gain was 11.03\u2009\u00b1\u20093.54\u2009mm, the mean horizontal bone gain was 7.18\u2009\u00b1\u20092.00\u2009mm, and the mean graft length was 28.19\u2009\u00b1\u200911.01\u2009mm. A total of 217 implants were placed in the augmented regions. On implant level, a mean vertical bone gain of 10.44\u2009\u00b1\u20093.44\u2009mm and a mean horizontal bone gain of 6.54\u2009\u00b1\u20091.86\u2009mm were measured. Over a 43\u2010month observation period, mesial and distal marginal bone loss averaged 0.44\u2009\u00b1\u20090.92\u2009mm and 0.49\u2009\u00b1\u20091.05\u2009mm, respectively.
