About this study

Official title: The OmniMax MMF System: A Cohort Study for Clinical Evaluation

OmniMax MMF system was designed as a device with faster application/removal time, less mucosal tissue overgrowth over the plates and screws, better tolerance for placement over prolong periods of time, better patient hygiene and a lower risk for further treatments secondary to root damage from the insertion of the screws, compared to the standard of care for maxillo-mandibular fixation and other hybrid systems. This clinical trial intends to highlight the clinical benefits of the OmniMax MMF system applied to patients undergoing repair of uncomplicated mandibular fracture(s) for whom OmniMax MMF system is used as a single mean for maxillo-mandibular fixation.

Read the detailed description

The objective of this study is to highlight and evaluate the clinical benefits of OmniMax MMF system applied to patients undergoing repair of uncomplicated mandibular fracture(s). A total of 50 subjects involved in trauma events resulting in uncomplicated mandibular fracture(s) will be enrolled at up to 5 sites from 3 surgical subspecialties: maxillofacial surgery, ENT, and plastic surgery. Subjects considered for participation will receive OmniMax MMF system for maxillo-mandibular fixation for a period of 4 to 8 weeks. Incidence of root damage associated with screw insertion, time for implantation and removal of the device, oral hygiene during the maxillomandibular fixation period, mucosal overgrowth, gingival necrosis, post-operative pain, stability of the occlusion, fracture healing, patient overall satisfaction/compliance with length of treatment, incidence of glove perforation and accidental puncture, will be evaluated in all participants who remain in IMF post-operatively. Adverse Events associated with the use of OmniMax MMF system will also be collected.

What participants receive

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

  • OmniMax MMF systemDevice

    Also called OmniMax

    OmniMax MMF system consists of arch bars and screws that work together to achieve temporary fixation of the maxilla and mandible to provide indirect or passive stabilization of fractures and maintenance of occlusion in the oral and maxillofacial region. The arch bars have hooks designed to accommodate either wires or elastic bands for temporary maxillomandibular fixation (MMF) either intraoperative or postoperative.

Study groups in NCT03075865
Study groupRoleWhat they receive
OmniMax MMFPatients involved in trauma events will receive intermaxillary fixation with OmniMax MMF system for temporary stabilization of mandibular fracture(s) to maintain proper occlusion during surgery and allow for postoperative fracture healing.
Receives: Device: OmniMax MMF system

What is being measured

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

  1. Root Damage

    Dental root damage can be caused from insertion of the screws at time of implantation. Some of these events may require further medical or surgical treatment

    Measured: 6 weeks

Secondary outcomes (2)
  1. Time for Implantation of OmniMax MMF

    The OmniMax MMF system, with a better segmentalized design and extended screw slots, allows for fixation of this device using less quantity of screws for fixation (compared to other hybrid systems). This system may impact the efficiency of the medical care by significantly reducing the operative time.

    Measured: Operative

  2. Tissue necrosis and mucosal overgrowth

    The reduced number of screws needed to fixate a full OmniMax MMF system (8 versus up to 14 in other bone-borne systems) is expected to improve the post-operative gingival tissue health, avoiding soft tissue irritation, overgrowth, compression and necrosis of the gingival area.

    Measured: 6 weeks

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Root Damage (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 NCT03075865, which also lists 22 linked publications.

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 19 Jul 2021.
