A Cohort Study for Clinical Evaluation of OmniMax MMF System
Study Details
Study Description
Brief Summary
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.

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.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| OmniMax MMF Patients 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. |
Device: OmniMax MMF system
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.

Outcome Measures
Primary Outcome Measures
- Root Damage [6 weeks]
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
Secondary Outcome Measures
- Time for Implantation of OmniMax MMF [Operative]
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.
- Tissue necrosis and mucosal overgrowth [6 weeks]
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.
Other Outcome Measures
- Patient Satisfaction [6 weeks]
Less screws for fixation and design of the device to protect the soft tissue is expected to increase the level of patient satisfaction and patient compliance with both, the oral hygiene and the length of fixation period.
- Gloves Perforation and Accidental Puncture [Operative]
Design of OmniMax MMF system is expected to reduce the risk for accidental glove perforation and/or wire puncture during implantation of the device.

-
Use of OmniMax MMF system as a single mean for IMF (maxillary plate and mandibular plates together with no other device combined, such as Erich bars or IMF screws).
Exclusion Criteria:

-
History of radiation therapy to the head or neck region.
-
Limited blood supply to the area of device application.
-
Insufficient quantity or quality of bone.
-
History of foreign body sensitivity.
-
History of previous use of bisphosphonates (i.e. alendronate, pamidronate, neridronate, olpadronate, ibandronate, risendronate, zolendronate).
