An absorbable collagen membrane was placed over the graft material and the surgical site was sutured. Cone\u2010beam computed tomography was taken immediately and 5\u2009months after ARP.

However, one patient who received split\u2010mouth treatment was excluded, resulting in data from 38 patients being analyzed. In radiological evaluation, the changes in midbuccal alveolar bone height at 5\u2009months were \u22120.753\u2009\u00b1\u20090.112 and \u22121.018\u2009\u00b1\u20090.111\u2009mm in the SBX group and PBX groups, respectively (<jats:italic>F<\/jats:italic>\u2009=\u20092.895; <jats:italic>p<\/jats:italic>\u2009=\u20090.098; mean difference [MD] 0.265; 95% confidence interval [CI]\u2009=\u2009\u22120.051 to 0.582). Changes in the horizontal ridge width were measured at three levels (\u22121, \u22123, and \u22125\u2009mm) below the most coronal aspect of the crest and showed a decrease in both groups, with no significant differences between the groups. The percent new bone area of the SBX group (39.156\u2009\u00b1\u20092.505) was significantly different from that of the PBX group (22.749\u2009\u00b1\u20092.476) (<jats:italic>F<\/jats:italic>\u2009=\u200922.171; <jats:italic>p\u2009&lt;<\/jats:italic>\u20090.001; 95% MD 16.407; CI\u2009=\u20099.333 to 23.481).
