Background: Fractures of the mandibular corpus and angulus are affected by different forces result from different
strength of the muscles that influenced them. Therefore, it is presumed that there is a different in healing rate.
Fractal dimension radiologic analysis assesses the trabecular pattern, due to it can be used to observe the healing
process of bone fractures.
Purpose: The study aimed to compare the healing process of mandibular corpus and angulus fractures with fractal
dimension analysis (FD) of trabecular patterns on panoramic radiographs through ImageJ software as consideration
to

combined with maxillomandibular fixation (MMF) at Hospital in 2017–2023. Observations were
carried out on postoperative 1st day, 2nd week, 8–13th week and >
13th week respectively.
Results: Twenty-five subjects who met the inclusion requirements were involved in the study. The results of Two-
Way ANOVA statistical test and Fisher’s LSD post-hoc showed that the FD values of corpus fracture were
significantly greater than that of mandibular angulus with p 0.000 (H1), 0.003 (H2), 0.03 (H3), 0.000 (H4)
respectively. In both groups of mandibular corpus and angulus fractures, there was a significant effect of time
with p =
0.00 in each group. The longer the observation time, the more trabeculae patterns were formed in the
healing process of corpus and angulus fractures.
Conclusion: Post ORIF observation of corpus fracture shows a greater trabecula formation value which indicates
faster healing when compared to mandibular angulus fracture. |
