the study aims to compare 3D Interlocking miniplates with conventional miniplates in management of mandibular parasymphyseal fractures both clinically and radiographically.

A total of 12 patients with recent bilateral parasymphyseal mandibular fractures were treated with 3D Interlocking miniplates on one side and with conventional two miniplates in the other side. Clinical evaluations were carried at multiple intervals up to 6 weeks postoperatively, with radiographic assessments performed immediately after surgery and at 12 weeks to measure mean bone density at the fracture line

Inclusion Criteria:

• patients with recent bilateral mandibular fracture located in the mental foramina region.
• adults without gender predilection who agreed to follow-up,
• fractures requiring open reduction and internal fixation, and
• those medically fit for general anesthesia were included

Exclusion Criteria:

• medically compromised patients,
• fractures with infection,
• pathological or old fractures,
• completely edentulous patients,
• comminuted fractures

all data will be de-identified to protect the participant data. patients signed an informed consent for the use of their medical records and data for study

Fracture sides were allocated in a 1:1 ratio using an on-site computer software system with concealed allocation through sequentially numbered, opaque, sealed envelopes (SNOSE). Group A was treated with 3D-interlocking miniplate in one side, and Group B with conventional double miniplates configration in the other side.
