The tmCMF Solution is intended for use as a software system and image segmentation system for the transfer of imaging information from a medical scanner such as a CT-based system. The input data file is processed by the tmCMF Solution, and the result is an output data file that may then be provided as digital models or used as input to a rapid prototyping portion of the system that produces physical outputs including anatomical models, surgical guides, and dental splints for use in maxillofacial and mandibular surgery. The surgical guides and dental splints are intended to be used for the maxillofacial and mandibular bone in maxillofacial and mandibular surgery. The tmCMF Solution is also intended as a preoperative software tool for simulating/evaluating surgical treatment options.

## V. DEVICE DESCRIPTION SUMMARY
The TechMah CMF (tmCMF) Solution is a family of personalized product solutions for trauma and reconstruction procedures in the mandible and midface. The solution is comprised of Surgeon Review Tool (SRT) software, and maxillofacial and mandibular surqical instruments (surgical quides, anatomical models, and dental splints). The surqical instruments are patient-specific devices and are designed utilizing CT and dental scan patient image data.
Surgical guides are patient-specific devices or templates that are based on preoperative software planning and are designed to fit a specific patient. These guides are used to assist a surgeon in transferring the pre-operative plan to the surgery by guiding the marking of bone for plate fixation screws and the position of the osteotomy marking slots. Surgical guides are available for treatment (maxilla and mandible) and harvesting (fibula, iliac crest, and scapula). Guides can be used in conjunction with anatomical models to verify anatomical positioning and fit.
Anatomical models are patient-specific models that are based on pre-operative anatomy and surgical planning specific to a patient. These models are used to assist a surgeon in transferring the pre-operative plan to the surgery by representing preoperative, intra-operative, and post-operative anatomical models as guidance. Anatomical models are available for treatment (maxilla and mandible), and harvesting (fibula, iliac crest, and scapula) anatomy. Anatomical models can be used to check
{6}------------------------------------------------
quide fit.
Dental splints are patient-specific devices or templates that are based on preoperative software surgical planning and are designed to fit a specific patient. Dental splints are available as single splint desired occlusions or combined splint-in-splint option. These templates are used to assist a surgeon in transferring the pre-operative plan to the surgery by guiding the dental alignment of bone and teeth.
The Surgeon Review Tool (SRT) software is used by surgeons for the review and approval of surgical plans and surgical instrument designs. The SRT software is accessed through a web interface from a surgeon's device.
## VI. INTENDED USE/INDICATIONS FOR USE
The tmCMF Solution is intended for use as a software system and image seqmentation system for the transfer of imaging information from a medical scanner such as a CT-based system. The input data file is processed by the tmCMF Solution, and the result is an output data file that may then be provided as digital models or used as input to a rapid prototyping portion of the system that produces physical outputs including anatomical models, surgical guides, and dental splints for use in maxillofacial and mandibular surgery. The surgical guides and dental splints are intended to be used for the maxillofacial and mandibular bone in maxillofacial and mandibular surgery. The tmCMF Solution is also intended as a preoperative software tool for simulating/evaluating surgical treatment options.

## VIII. INDICATIONS FOR USE COMPARISON
The tmCMF Solution has equivalent indication for use as its predicate device. The primary indication is to utilize pre-operative imaging data to perform surgical case planning and create patient-specific instrumentation to transfer the pre-operative plan on the patient in the operating room.
## Differences
- . The predicate specifically refers to maxillofacial surgery, whereas the subject device covers both maxillofacial and mandibular surgeries, which is equivalent to the reference device (K103136).
- . The predicate device does not include graft harvesting surgical guides, whereas the subject does. However, the predicate device (K120956) used by the current predicate (K192282) also included harvesting surgical guides, which is equivalent to the reference device (K210347)
- . The predicate device has a limited contact for the splint whereas the subject device has a prolonged contact for splints to allow for post-op usage of up to 30 days. However, the predicate device (K120956) used by the current predicate (K192282) also has a prolonged contact for splints to allow for postop usage of up to 30 days, which is equivalent to the reference device (K210347).
## IX. TECHNOLOGICAL COMPARISON (WITH PREDICATE DEVICE)
### Similarities to Predicate
The tmCMF Solution has the same intended use and similar technological characteristics as the identified predicate device. The system employs similar fundamental technologies as the identified predicates including input case data, manipulation, and surgical planning. The principles of operation and technological characteristics are either identical or substantially equivalent to the predicate. The system has similar technological characteristics including:
- System inputs: images from medical scanners (ex: CT), dental models, and/or . implant files (.STL)
- . System outputs: physical and/ or digital outputs such as patient-specific anatomical models, guides, and splints
- Materials: biocompatible polymers
- Sterility assurance level of 1x10-6 ●
The intended use of the subject device and the predicate both provide tools and accessories (software for image manipulation, anatomical models, splints, and guides) for use in reconstructive surgery. Additionally, both the subject and the predicate device are intended to be used by trained personnel with active support
{10}------------------------------------------------
from the surgeon.
Differences to Predicate
- The predicate specifically refers to maxillofacial surgery, whereas the subject ● device covers both maxillofacial and mandibular surgeries.
- . The predicate device does not include graft harvesting surgical quides, whereas the subject does. However, the predicate device (K120956) used by the current predicate (K192282) also included harvesting surgical guides.
- The predicate device has a limited contact for the splint whereas the subject device has a prolonged contact for splints to allow for post-op usage of up to 30 days. However, the predicate device (K120956) used by the current predicate (K192282) also has a prolonged contact for splints to allow for postop usage of up to 30 days.
## X. TECHNOLOGICAL COMPARISON (WITH REFERENCE DEVICES)
Reference device K170419:
- The reference device served as a technologically equivalent device for the ● Surgeon Review Tool (SRT).
Reference device K103136:
- . This reference device was used to establish performance equivalence data.
Reference devices K210347 and K120956:
- The reference devices served as the basis for establishing equivalence on physical product features and offerings, product material compositions and their manufacturing processes. The reference devices encompass anatomical models, surgical guides, and dental splints, with the subject device utilizing similar product features and identical materials to ensure a state of equivalence.
The addition of the reference device comparison presents another substantially equivalent device with identical physical outputs, materials, and manufacturing processes.
