January 20, 2026 updated by: Suez Canal University

Evaluation of the Efficacy of Custom-Made Inter-flex Three-Dimensional Plate in Treatment of Mandibular Fracture A Randomized Controlled Clinical Trial

The goal of this clinical trial is to learn if The use of a 3D-designed Inter-flex plate will achieve safe and desirable anatomical & functional restoration with reduced operative time in mandibular fracture,

  • Improvement of occlusal and inter-cuspal relation in addition to stabilized intra-fragmentary mobility,
  • Offer greatest resistance to displacement

Detailed Description

Mandibular fractures most commonly accompany facial trauma, with nearly half of the patients requiring surgical repair. The treatment of fractures prioritizes the restoration of functionality through The realignment of fractured segments. Conventional methods, such as titanium plates, have been employed for this purpose; however, certain limitations have been observed, such as there is a chance of potential infection and mal-union in mandibular fracture site. Leading to the development of patient specific plates. Furthermore, recent advancements in digital technology in Dentistry enable creation of virtual models and simulations of surgical Procedures. Aim: Is to evaluate the effect of custom-made Inter-flex three dimensional plate vs conventional ready-made Titanium plates in Management of Mandibular Fracture Methodology: This study will be conducted on 20 sites with mandibular fracture in patients. The sites of fracture will be divided into two groups (Group I and Group II) randomly and equally via www.randomizer.org Group I: site with mandibular fracture will be treated with custom made Inter-flex three dimensional plate in site of mandibular fracture, Group II: site with mandibular fracture will be treated with a ready-made Titanium plates in site of mandibular fracture. The postoperative clinical evaluation included presence of infection, stability of the mandibular lower border, state of occlusion, maximal mouth opening. Postoperative radiographic examinations to evaluate the accuracy of reduction and bony union using postoperative c.t 24hour and 3 months by measuring the inter-fragmentary gap and the Intergonial distance.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mobility of fracture segments
Time Frame: 24 hour after surgery

assessed through bimanual digital manipulation

  • Stable >> no movement of fragments.
  • Nonstable >> presence of movement.
24 hour after surgery
State of occlusion
Time Frame: after 24 hours and after 3 months of surgery
will be assessed by asking the patient to bite in maximum intercuspation at each follow-up (intact/deranged) also by recording molar relation as (satisfactory or deranged).
after 24 hours and after 3 months of surgery
Radiographic evaluation
Time Frame: 24 hour after surgery and after 3 months
  • The linear inter-fragmentary gap between the fractured segments in mm
  • Intergonial distance was measured between the most inferior, lateral, and posterior points of the mandible bilaterally as determined on CT in mm.
24 hour after surgery and after 3 months
