Indications for Use
The OsteoMed ICON IMF Screw System is intended and indicated for the temporary ligature and wire lock fixation for temporary constriction and stabilization of fractured bone segments in the oral cavity in conjunction with primary fixation devices.
Device Story
System consists of 2.0mm and 2.4mm titanium alloy screws and stainless steel ligature wire; used for temporary stabilization of fractured jaw bone segments. Implantation involves either pilot hole creation (standard screws) or self-drilling (AutoDrive screws). Instruments include drill bits, wire cutters, pliers, drill guides, and screwdrivers. Used in oral cavity by clinicians; screws provide rigid fixation points for wire to prevent bone segment movement. Benefits include temporary stabilization of fractures during healing. Non-sterile; requires sterilization before use.
Clinical Evidence
Bench testing only. No clinical data. Performance testing included failure torque, insertion torque, pull-out force, and bending force testing per ASTM F543. Results demonstrated equivalence to primary predicate (K962774) and reference predicate (K974785).
Technological Characteristics
Materials: Titanium alloy (ASTM F136) for screws, stainless steel for wire. Instrumentation: stainless steel, anodized aluminum, medical grade polymer. Principle: Rigid fixation and wire lock stabilization. Connectivity: None. Sterilization: Non-sterile, requires user sterilization. Form factor: 2.0mm/2.4mm diameter screws, 10-20mm lengths.
Indications for Use
Indicated for temporary ligature and wire lock fixation for temporary constriction and stabilization of fractured bone segments in the oral cavity in conjunction with primary fixation devices.

# Substantial Equivalence Discussion:
The OSTEOMED 2.0mm ICON Standard IMF Screw and the 2.0mm ICON AutoDrive IMF Screw are the same as the predicate device (2.4mm QuickFix MMF Screw, K962774) in the following ways:
- The screws have the same Regulatory Classification (21 CFR 872.4880 DZL)
- The screws have the same indication for use.
- The technology and features of the screws are the same (screws to fixate and allow ligature with wire)
- The range of the screw length is the same as, or encompassed by, that of the predicate:
- o Overall Length = 10mm 20mm
- o Thread Length = 5mm 15mm
- . The length of the screw head, the head diameter, and cross-sectional areas through the wire holes are the same as the predicate device.
- . The 2.0mm ICON Standard IMF Screw has the same number of wire fixation holes (1) as the predicate
{6}------------------------------------------------
- The screws are manufactured from the same materials (Titanium alloy per ASTM F136) as the predicate and therefore have the same biocompatibility.
- The instrumentation and materials used in conjunction with these screws are the same
- The screws are packaged and sterilized in the same manner and same parameters as the predicate device.
Differences between the new devices and the predicate, do not affect safety and effectiveness
- The 2.0mm ICON AutoDrive IMF Screw has more wire fixation holes (2) than the predicate (1) ●
- The 2.0mm ICON Standard IMF Screw has a smaller cross-sectional area through the wire fixation holes (1.43 mm²) than the predicate (2.04 mm²)
- The 2.0mm ICON AutoDrive IMF Screw has a different tip (sharp, pointed, single threadcutting flute) than the predicate (blunt, rounded) but was equivalent to the reference predicate.
The performance testing comparison listed below showed the new devices were equivalent and did not raise new safety and effectiveness issues.
## Performance/Clinical Data:
The OsteoMed ICON IMF Screws (2.0mm Standard IMF screws and the 2.0mm AutoDrive IMF screws) were compared to the OsteoMed QuickFix 2.4mm standard MMF Screws (K962774-primary predicate) and the 2.0mm AutoDrive Screws (K974785-reference predicate). The 2.0mm AutoDrive IMF screws and the 2.0mm standard IMF screws underwent verification testing to ensure that the design features meet the required mechanical strength criteria for their intended use compared to the predicate device. The intended use of the OsteoMed ICON IMF Screw System is the same as OsteoMed 2.4mm QuickFix screw system (K962774).
The performance testing included failure torque testing of the new devices and the predicate devices in accordance with ASTM F543. All devices met the minimum failure torque requirement based on screw diameter according to the standard. Also, insertion torque testing in accordance with ASTM F543 was performed for all devices met the required failure torque to insertion torque (FT/IT) ratio of FT/IT > 1.0 according to the standard. Lastly, pull-out force and bending force testing was performed on the new devices using equivalent methods to those shown in the primary predicate 510k K962774 and compared against the predicate device results in K962774. The performance testing showed that the new devices were equivalent to the predicate device. Simulated use was performed as part of validation for the new screws and were found to be equivalent to the predicate device.
Biocompatibility and Sterilization testing was justified to the already tested predicate device. No changes to materials, packaging, or sterilization were made, therefore the new devices are equivalent to the predicate device.
OsteoMed believes that these non-clinical tests have demonstrated that these devices are safe and effective as the predicate device; therefore, clinical testing is not required to support substantial equivalence.
## Substantial Equivalence:
The substantial equivalence of the OsteoMed ICON IMF Screw System is based on similarities in intended use, indications for use, material, function, technology, performance, design, sterilization, and operational principles to the OsteoMed QuickFix (K962774, primary predicate) and design, material and operating principles as the AutoDrive self-drilling features for the OsteoMed AutoDrive Bone Screw (K974785) reference predicate.
{7}------------------------------------------------
## Conclusion:
Substantial equivalence was shown through failure torque testing, insertion torque testing, pull-out force testing, and bending testing when compared to known standards and to the predicate devices. The indications, design, technology and operational principles are similar between the subject devices and primary predicate OsteoMed 2.4mm QuickFix MMF Screw (K962774), and reference predicate OsteoMed 2.0mm AutoDrive Screw (K974785), therefore OsteoMed believes that the OSTEOMED 2.0mm ICON Standard IMF Screw and OSTEOMED 2.0mm ICON AutoDrive IMF Screw do not raise any new safety or effectiveness issues.
The assessment of the non-clinical data demonstrated the devices were as safe and effective as the predicate devices OsteoMed QuickFix (K962774) and AutoDrive Bone Screw (K974785). In conclusion, the OsteoMed IMF Screw System have been evaluated and proven to be substantially equivalent to the predicate device.
