About this study
Official title: Clinical and Radiographic Evaluation of Pin Buckle Bone Plates for Management of Anterior Mandibular Fractures: A Randomized Study
This randomized clinical study aims to evaluate the clinical and radiographic outcomes of a novel Pin Buckle bone plate compared with conventional two-miniplate fixation for the management of anterior mandibular (symphysis and parasymphysis) fractures. Twenty adult patients requiring open reduction and internal fixation will be randomly allocated into two equal groups. The study group will receive fixation using the Pin Buckle bone plate, while the control group will be treated using conventional titanium miniplates.
Clinical outcomes including pain, edema, wound healing, and postoperative complications will be evaluated during the postoperative follow-up period. Radiographic assessment using computed tomography (CT) will be performed immediately after surgery and at 6 months to evaluate bone density. The study seeks to determine whether the Pin Buckle bone plate provides improved postoperative healing and functional outcomes compared with conventional miniplate fixation.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Pin Buckle Bone PlateDevice
A titanium Pin Buckle bone plate used for internal fixation of anterior mandibular fractures following open reduction.
Conventional Titanium MiniplatesDevice
Conventional titanium miniplates used for internal fixation of anterior mandibular fractures following open reduction according to Champy's principles.
| Study group | Role | What they receive |
|---|---|---|
| Pin Buckle Bone Plate | Experimental | Participants underwent open reduction and internal fixation of anterior mandibular (symphysis or parasymphysis) fractures using the Pin Buckle bone plate. Clinical and radiographic outcomes were evaluated during the postoperative follow-up period. Receives: Device: Pin Buckle Bone Plate |
| Conventional Two-Miniplate Fixation | Active comparator | Participants underwent open reduction and internal fixation of anterior mandibular (symphysis or parasymphysis) fractures using conventional titanium two-miniplate fixation according to Champy's principles. Clinical and radiographic outcomes were evaluated during the postoperative follow-up period. Receives: Device: Conventional Titanium Miniplates |
What is being measured
The primary outcome is the main question the study is designed to answer.
Radiographic Bone Density
Bone density at the fracture site was measured in Hounsfield Units (HU) on multislice CT using standardized regions of interest to evaluate osseous healing.
Measured: Preoperative, immediately postoperative and after 6 months
Wound Healing
Wound healing was assessed clinically using the Southampton Wound Assessment Scale, which evaluates postoperative wound healing based on the presence and severity of normal healing, erythema, bruising, discharge, wound dehiscence, and infection. Higher grades indicate poorer wound healing.
Measured: Day 1, Day 7, and Day 14
Secondary outcomes (2)
Postoperative Pain
Pain intensity was assessed using a 10-cm Visual Analogue Scale (VAS), where 0 indicated no pain and 10 indicated the worst pain imaginable.
Measured: Day 1, Day 7, and Day 14
Postoperative Edema
Facial edema was evaluated clinically by visual inspection and palpation and categorized as none, low-grade, intermediate-grade, or high-grade according to the severity of facial swelling.
Measured: Day 1, Day 7, and Day 14

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Radiographic Bone Density (time frame: Preoperative, immediately postoperative and after 6 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
