The summary does not mention AI, ML, or related terms, and the device description focuses on patient-specific 3D printed implants and accessories for surgical planning transfer, not AI/ML-driven analysis or decision support.
Yes
The device is described as an implant system for bone repositioning, fixation, and reconstruction of the maxillofacial skeleton, midface, mandible, and chin, which directly addresses medical conditions and aims to restore normal function.
No
The device is an implant system intended for bone repositioning, fixation, and reconstruction of the maxillofacial skeleton, midface, mandible, and chin. It is a treatment device, not designed to diagnose a condition.
No
The device description explicitly states it is a "System" that provides "patient-specific plates and patient-specific osteotomy and drill accessories," which are physical components. The performance studies also detail mechanical and biocompatibility testing of these physical implants and accessories.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The TruMatch CMF Titanium 3D Printed Implant System is a surgical implant system used for bone repositioning, fixation, and reconstruction within the patient's body. It is a physical device implanted during surgery.
- Intended Use: The intended use clearly describes surgical procedures on the maxillofacial skeleton.
- Device Description: The description focuses on patient-specific plates and surgical accessories, not analysis of biological samples.
- Input: The input is a CT scan of the patient, which is used for planning the surgical procedure and creating the patient-specific implants, not for analyzing biological markers.
The device is a surgical implant system, not a diagnostic tool that analyzes samples outside the body.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-clinical testing was conducted including:
- Performance testing of the TruMatch CMF Titanium 3D Printed implants and accessories:
- Mechanical performance of the subject device compared to the predicate devices: ASTM F382 (static and fatigue four point plate bending). Results: The subject device has a higher static bending strength and has fatigue bending properties compared to the predicate devices.
- Compatibility testing: Combination of user need validation lab and engineering rationale. Results: The subject device is compatible with the Synthes fixation system.
- Biocompatibility testing:
- Cytotoxicity: ISO 10993-5 (L929 Neutral red uptake Cytotoxicity). Conclusion: no cytotoxic effect.
- Sensitization: ISO 10993-10 (Kligman Maximization test). Conclusion: in compliance with requirements of the ISO 10993-10 guidelines.
- Intra-cutaneous reactivity: ISO 10993-10 (Intra-cutaneous Injection Test). Conclusion: in compliance with requirements of the ISO 10993-10 guidelines.
- Systemic toxicity: ISO 10993-11 (Systemic injection test). Conclusion: test passed and is considered negative based on standards set by ISO 10993-11.
- Chemical characterization: ISO10993-18 (Chemical Characterization of Materials (2005)). Conclusion: chemical characterization as per report.
- Assessment of allowable limits for leachable substances: ISO 10993-17 (Establishment of allowable limits for leachable substances). Conclusion: no toxicological concern remains, further biological testing are considered not justified.
- Sterilization testing:
- Steam sterilization validation according to ISO 17665-1:2006, ISO 11737-2:2009 and ISO 14161:2009. Conclusion: The implants, accessories and models can be sterilized to a SAL of 10^-6 using the recommended steam sterilization instructions.
Clinical performance was assessed by analyzing 5 clinical studies from published literature including patients from 8-21 years and adults. Key results include:
- Schendel et al. 1978: The surgical-orthodontic correction of mandibular deficiency in growing children (8 to 16 years of age) can be employed to achieve excellent results. Mandibular advancement by a modified sagittal osteotomy proves to be an acceptable procedure with good skeletal stability. Dentofacial growth following surgery will be harmonious and not adversely affected. Direction of growth varies, with the mandibular plane angle becoming more vertical with an increasing mandibular plane angle.
- Precious et al. 1985 (1) & (2): Surgery for the correction of dentofacial deformities can be performed on children and adolescent patients with little morbidity and few complications. The correction of dentofacial deformities in children using orthodontic and surgical means can be carried out reliably if careful attention is paid to the systematic evaluation of each deformity.
- Li et al. 2017: The maximum positional and orientational differences between the planned and post-operative positions were within 1.1 mm and 3°. The system is capable of accurately and effectively transferring the surgical plan without the use of a surgical splint. No complications were reported in the article.
- Heufelder et al. 2017 (Subject device): In this study all the operations were performed successfully, without any unexpected incidence. The results demonstrate the high predictability of maxillary positioning by CAD/CAM fabricated customized surgical guides and patient specific osteosynthesis plates.

Both the subject device and all predicates are manufactured in commercially pure titanium and have the same fixation method.
Both the subject device and the predicate devices are not provided sterile and have the same sterilization method, moist heat.
The manufacturing technique differs between the subject device and the reference devices. While the subject device is manufactured by additive manufacturing, the predicate devices are machined.
The subject device is made patient specific, manufactured from patient CT scan data, while the predicate devices are provided in a standard shape and adapted to the patient intra-operatively.

| Results and analysis | The surgical-orthodontic
correction of mandibular
deficiency in growing children (8
to 16 years of age) can be employed to
achieve excellent results. Mandibular
advancement by a modified sagittal
osteotomy proves to be an acceptable
procedure with good skeletal
stability.
Dentofacial growth following surgery
will be harmonious and not adversely
affected. Direction of growth varies,
with the mandibular plane angle
becoming more vertical with an
increasing mandibular plane angle. | Surgery for the correction of
dentofacial deformities can be
performed on children and
adolescent patients with little morbidity
and few complications. | The correction of dentofacial
deformities in children using
orthodontic and surgical
means can be carried out reliably
if careful attention is paid to the
systematic evaluation of each
deformity. Selected cases from more
than 100 children whom we have
treated are presented to
illustrate salient clinical features of
specific deformities. | The maximum positional and
orientational differences between
the planned and post-operative
positions were within 1.1 mm and
3°. The system is capable of
accurately and effectively
transferring the surgical plan
without the use of a surgical splint. No
complications were reported in the
article. | In this study all the operations were
performed successfully, without any
unexpected incidence.
The results demonstrate the
high predictability of maxillary positioning
by CAD/CAM fabricated
customized surgical guides and patient
specific osteosynthesis plates. |
Based on published literature findings of the subject device and similar bone plate devices and a risk analysis, it can be concluded that the subject device can be used for treatment of the adolescent patient population (greater than 12 to 21 years of age), if additional precautions are taken into account:

Important considerations in achieving quality outcomes for the treatment of facial deformities in growing patients include accurate diagnosis and patient selection and proper treatment planning.
Conclusion
Non clinical tests and a review of clinical performance data demonstrate that the TruMatch CMF Titanium 3D Printed Implant System is substantially equivalent to the predicate devices.
