Six months after the augmentation, dental implants were placed in all patients, and a core biopsy was performed for histological evaluation in addition to clinical and radiographic evaluation using cone beam computed tomography. The primary outcome was the mean overall clinical ridge width gain (CRWG) after 6\u00a0months of augmentation. Secondary outcomes were the overall radiographic ridge width gain (RRWG) after 6\u00a0months of augmentation and descriptive histological analysis with histomorphometric assessment of bone fraction %.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All sites healed uneventfully, and the mean overall CRWG 6\u00a0months after augmentation was 3.52\u00a0\u00b1\u00a00.56\u00a0mm and 2.24\u00a0\u00b1\u00a00.86\u00a0mm in the D and A groups, respectively, with statistically significant difference between them (<jats:italic>P<\/jats:italic>\u00a0\u2264\u00a0.001).
