Figure 1

Two CBCTs of test group superimposed by Amira software, showing bone present at T0 or at T1 (A1 and B1, respectively); soft tissue present at T0 or at T1 (A2 and B2, respectively), and bone and soft tissues present both at T0 and T1 (C1 and C2, respectively). Schneiderian membrane hypertrophy appears considerably reduced during the healing period.
