Mandibular Fracture TraumaNCT07058597
Fixation of Fractures at Anterior Transition Zone Using Three Different Miniplates Configurations
A study testing Twinfork plate, 3D-interlocking plate and Miniplate in people with Mandibular Fracture Trauma and Mandible Fracture, run by Alexandria University at 1 site in Egypt.
Trial summary
Fractures involving the anterior transition zone of the mandible are frequently encountered and hold particular clinical significance due to the presence of the mental nerve. Consequently, mental nerve paresthesia is among the common postoperative complications associated with these fractures. Read more about this study

About this study
Official title: Assessment of Mental Nerve Integrity During Fixation of Fractures at Anterior Transition Zone Using Three Different Miniplates Configurations
Fractures involving the anterior transition zone of the mandible are frequently encountered and hold particular clinical significance due to the presence of the mental nerve. Consequently, mental nerve paresthesia is among the common postoperative complications associated with these fractures. To assess the mental nerve functional integrity during fixation of fractures at the anterior transition zone using twin fork-miniplate, 3d interlocking miniplate and two miniplates
Read the detailed description
A total of 36 patients (they were divided into three groups 16 patients in each group ) with parasymphyseal-body fractures , one group was treated with twin-fork miniplate , the second group was treated using 3d interlocking miniplate and the third one was treated with conventional two miniplates. Postoperative evaluation of the mental nerve was conducted using both subjective and objective methods at intervals of 24 hours, and at 1, 4, 6 and 12 weeks. Furthermore, an electrophysiological study was performed at 6 weeks postoperatively to measure the mental nerve's amplitude, onset latency and conduction velocity

What is being measured
The primary outcome is the main question the study is designed to answer.
Sensory nerve function
Objective assessment by using a dental probe pressure to determine any sensory changes along the distribution of the mental nerve in comparison to the contralateral side (nociceptive method).
Measured: 6 weeks
Secondary outcomes (1)
Radiographic evaluation for fracture healing
Preoperative CT scan will be obtained, immediate CT scan will be used to assess the adequacy of fracture line reduction and fixation, and then another CT will be taken at 12th week to estimate the mean bone density at the fracture line in comparison with the immediate postoperative scan.
Measured: 3 months

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Consequently, mental nerve paresthesia is among the common postoperative complications associated with these fractures. To assess the mental nerve functional integrity during fixation of fractures at the anterior transition zone using twin fork-miniplate, 3d interlocking miniplate and two miniplates

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Sensory nerve function (time frame: 6 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07058597, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jul 2025.
