About this study

Official title: Optimized Osteosynthesis: A Comparative Analysis of Bone Mineral Density Recovery in Mandibular Body Fractures Using Patient-Specific Versus Conventional Plates (A Randomized Controlled Clinical Trial)

The goal of this randomized controlled clinical trial is to evaluate and compare the bone mineral density (BMD) recovery following open reduction and internal fixation (ORIF) of mandibular body fractures using patient-specific plates versus conventional plates. Bone density at the fracture site will be quantified using Hounsfield Units (HU) on computed tomography (CT) scans.

The main question it aims to answer is: Do patient-specific plates provide a superior recovery of bone mineral density at the fracture site compared to conventional plates in patients undergoing fixation for mandibular body fractures?

Read the detailed description

This parallel-group, randomized controlled clinical trial evaluates the efficacy of patient-specific (custom-designed) fixation plates compared to conventional plates regarding bone mineral density recovery in mandibular body fractures.

Upon consenting to participate, eligible patients requiring open reduction and internal fixation (ORIF) for mandibular body fractures will be randomly assigned to one of two groups:

  1. Group I (Intervention): Patients will receive patient-specific titanium plates pre-fabricated utilizing computer-aided design and computer-aided manufacturing (CAD/CAM) based on preoperative 3D computed tomography (CT) data.
  2. Group II (Control): Patients will receive conventional, standard stock titanium plates adapted manually during surgery.

All surgical procedures will be standardized and performed under general anesthesia by the same surgical team.

Radiological Assessment of Bone Density:

The primary outcome, bone mineral density recovery at the fracture site, will be analyzed using Hounsfield Units (HU). Patients will undergo multi-slice CT scanning at baseline (within 1 week) and at 6 months postoperatively to assess the recovery.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Open reduction and Internal fixation of a mandibular body fractureProcedure or surgery

    Patient-Specific titanium plates designed using virtual 3D planning software and fabricated via computer-aided manufacturing to match the patient's precise pre-injury mandibular anatomy.

  • Open reduction and Internal fixation of a mandibular body fractureProcedure or surgery

    Commercially available, standard stock titanium plates will be adapted and bent manually by the surgeon during the operation to fit the patient's mandibular anatomy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Bone density

    Bone mineral density recovery at the fracture site, will be analyzed using Hounsfield Units (HU).

    Measured: Patients will undergo multi-slice CT scanning at baseline (within 1 week) and at 6 months postoperatively to assess the recovery.

Secondary outcomes (2)
  1. Postoperative occlusion

    Number of participants achieving a satisfactory occlusion, defined as meeting three criteria simultaneously: dental midline deviation ≤ 1 mm, bilateral normal canine relationship, and bilateral normal molar relationship. Failure in any criterion is classified as unsatisfactory.

    Measured: One week postoperatively

  2. Incidence of Postoperative Neurosensory Dysfunction

    The number of participants who develop neurosensory dysfunction. Sensation is evaluated using the Two-Point Discrimination (2PD) test. Neurosensory dysfunction is defined as a binary categorical outcome where a participant fails to distinguish two distinct points at the standard clinical threshold (≤ 5 mm). Participants who require a distance greater than 5 mm to discriminate the two points are marked as having neurosensory dysfunction.

    Measured: One week postoperatively
