Product Description
Unlike arch bars that trap debris, the small IMF Screw System screws are isolated, facilitating easier cleaning around the fixation points and dramatically improving oral hygiene and reducing the risk of periodontal inflammation.
The self-drilling and self-tapping design allows for fast, simple placement and removal of the screws, significantly reducing surgical time and eliminating the need for arch bar manipulation and the associated risk of needle-stick injuries.
The system requires minimal soft tissue dissection, preventing trauma to the gingiva and periodontium that is often associated with arch bar placement and removal.
Each screw provides a strong, fixed anchor point in the cortical bone, ensuring secure intermaxillary fixation with wires or elastics for the duration of the healing or surgical procedure.
The system is used to temporarily fix the maxilla (upper jaw) and mandible (lower jaw) together to manage fractures of the jaws, condyles, and mid-face.
Used to achieve stable occlusion and guide bone healing following osteotomies (bone cuts) in complex orthognathic surgical procedures.
Often utilized as an adjunct to plate and screw fixation (ORIF) to establish and maintain the correct occlusal relationship.

The IMF Screw System is a modern method of Intermaxillary Fixation (IMF), a procedure that temporarily locks the upper and lower jaws together. Instead of using traditional metal arch bars wired around the teeth, this system uses small, self-drilling titanium screws placed in the bone above the tooth roots. These screws have small heads or hooks that serve as secure anchor points for wires or elastics to stabilize the jaws.
It is primarily applied in trauma surgery for stabilizing simple or complex fractures of the mandible or maxilla (jaw and mid-face). It is also extensively used in orthognathic surgery to maintain the new, corrected jaw position immediately following the bone cuts, ensuring the proper occlusion is maintained during the critical early healing phase.
The key advantages are safety, speed, and hygiene. The screw system greatly reduces the risk of needle-stick injury to staff and minimizes trauma to the gums and teeth. Since the fixation points are localized, patients can maintain significantly better oral hygiene, which is critical for reducing the risk of post-operative infection compared to bulky, food-trapping arch bars.
Biomechanically, the IMF Screw System provides strong, stable, and rigid fixation by anchoring directly into the cortical bone. This direct bone fixation ensures the wires or elastics apply force precisely where needed to hold the jaw in its correct relationship (occlusion) while the underlying fracture or osteotomy heals.
The technique involves placing the screws using a specialized hand-held driver, often under local anesthesia and light sedation, or during the main surgery. The self-drilling screw tip allows it to be inserted directly through the gingiva and into the cortical bone, minimizing incision requirements. Once placed, wires or elastics are run between the opposing screws on the maxilla and mandible.
Postoperative care requires the patient to maintain a liquid diet for the period of fixation. The great advantage of the IMF Screw System is the ease of cleaning the teeth and soft tissues, leading to reduced gingivitis and plaque buildup compared to the difficult hygiene associated with traditional arch bars.
The IMF Screw System from TOOLMED represents a significant advancement in intermaxillary fixation, offering a safer, faster, and more hygienic method of achieving temporary jaw immobilization. Its efficient application and superior patient tolerance make the IMF Screw System the modern standard of care for trauma and orthognathic procedures requiring occlusal stabilization.
