Abstract

Aim: This study was designed to evaluate of using 3D miniplates versus lag screws
in mandibular parasymphyseal fracture Subjects and Methods: fourteen patients with
parasymphyseal fractures were divided randomly into two groups and were treated
with 3D miniplates and 2 lag screws. The outcome parameters recorded were infection,
occlusion derangement, nerve affection, teeth related to fracture line. The data collected
was be analyzed statistically using (SPSS) V21. Results: The results showed that 2
cases in group (A), 3 cases in group (B) had postoperative infection. Four patients in
each group showed with slightly infection after one week this degree of malocclusion
disappeared. One patient had paresthesia in group (A), while 2 patients in group (B)
had paresthesia. There was no statistically significant difference between 3D miniplates
and lag screw system in all recorded parameters at all the follow ups. Conclusions: 3D
miniplates were found to be better than 2 lag screws in easy of surgery and operative
time. However, the lag screws were favorable for cases where fracture line was oblique.
