Table 3 Change of mean bone score of the intramembranous bone and endochondral bone over time

From: Use of mandibular chin bone for alveolar bone grafting in cleft patients

Type of graft bone Mean bone score
POD 1W (T1) POD 6M (T2) T1–T2 (p)a POD 1Y (T3) T1–T3 (p)a
Intramembranous bone (n = 12) 4.0 3.75 ± 0.62 0.514 3.67 ± 0.65 0.319
Endochondral bone (n = 18) 3.83 ± 0.51 3.67 ± 0.84 0.767 3.50 ± 1.04 0.542
  1. Type I has a score of 4, type II has a score of 3, type III has a score of 3, and type IV has a score of 1 (p < 0.05)
  2. POD 1W evaluation within 1 week after surgery, POD 6M evaluation between 3 and 6 months after surgery, POD 1Y follow-up evaluation 1 year after surgery
