Digital preoperative design was conducted for both groups. BRT surgeries were executed with or without the aid of DN in the two groups. Accuracy outcomes evaluated angular and linear deviations at the bone ring in the donor site (BR\u2010D), recipient site (BR\u2010R), and implant entry\/apex between planned and actual positions revealed by cone\u2010beam computed tomography. Vertical augmentation\u2010related outcomes, surgical complications, and patient\u2010reported outcomes were assessed over 6\u2009months.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Twenty\u2010four patients underwent surgery while one was lost to follow\u2010up. The DN group showed significantly lower mean (SD) BR\u2010R angular (3.58 [2.07] vs. 8.77 [4.20]\u00b0) and entry deviation (1.43 [0.51] vs. 2.01 [0.70]\u2009mm). For BR\u2010D, the DN group had significantly lower angular (4.80 [2.62] vs. 12.97 [6.26]\u00b0), entry (1.45 [0.96] vs. 3.52 [1.54]\u2009mm), and apex deviation (1.28 [0.64] vs. 3.50 [1.47]\u2009mm) compared to the FA group. Implant angular deviation (3.74 [2.14] vs. 9.17 [4.39]\u00b0) and apex deviation (1.75 [0.44] vs. 2.35 [0.82]\u2009mm) was significantly lower in the DN group.
