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 manufacturing portion of the system that produces physical outputs, including anatomical models, surgical guides, dental splints, and implants for use in maxillofacial, midface, and mandibular surgery. Implants are intended for bone fixation and reconstruction. restoration of bone defects, and intended to provide continuity in regions where the bone is missing and/or to augment the bone by means of an onlay device in the maxillofacial skeleton, midface, mandible, and chin in adolescents (greater than 12 to 21 years of age) and adults. The tmCMF Solution is also intended as a preoperative software tool for simulating/ evaluating virtual surgical treatment options.

TechMah CMF (tmCMF) Solution is a family of personalized product solutions for Reconstructive, Orthognathic, Trauma, and Augmentation procedures in the mandible and midface (including orbital floor, medial and lateral orbital walls). The solution is comprised of Surgeon Review Tool (SRT) software and maxillofacial and mandibular surgical instruments (surgical guides, anatomical models, and dental splints) and implants. The surgical instruments and implants are patient-specific devices and are designed utilizing CT and dental scan patient image data.

Surgical guides are patient-specific devices or templates based on pre-operative software planning 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/drilling of bone for plate fixation screws and the position of the osteotomy marking/cutting slots. Guides can be used in conjunction with anatomical models to verify anatomical positioning and fit. Surgical guides can be used with either tmCMF Solution patient-specific implants or compatible off-the-shelf DePuy Synthes implants.

Anatomical models are patient-specific models that are based on pre-operative anatomy and surqical planning specific to a patient. These models are used to assist a surgeon in transferring the pre-operative plan to the surgery by representing pre-operative, intra-operative, and post-operative anatomical models as quidance. Anatomical models can be used to check quide fit and facilitate the pre-bending of a non-patient-specific off-the-shelf plate.

Dental splints are patient-specific devices or templates based on pre-operative software planning designed to fit a specific patient. 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.

Implants are patient-specific devices that are based on pre-operative software planning designed to fit a specific patient. These implants are integral components for CMF (craniomaxillofacial) procedures, facilitating bone repositioning, fixation, reconstruction, and the restoration of bone defects. They are designed according to the pre-operative surgical plan to ensure continuity in regions where bone is absent and to provide structural integrity to the maxillofacial skeletal components, midface, mandible, and chin. This could include stabilizing fractured or intraoperatively cut bone, fixating harvested graft segments, or augmenting bone defects. Implants can be used in conjunction with surgical guides and anatomical models to assist with anatomical positioning and fit.

The Surgeon Review Tool (SRT) software is used by surgeons for the review of surgical plans, surgical instruments, and implant designs. The SRT software is accessed through a web interface.

The tmCMF Solution's acceptance criteria and the study proving it meets these criteria are detailed below.
1. A table of acceptance criteria and the reported device performance:

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

The document mentions "Cadaveric Benchtop Performance Testing" as part of the benchtop performance evaluation. However, it does not specify the sample size (number of cadavers or cases) used for this test set, nor does it explicitly state the country of origin or whether the data was retrospective or prospective. It only states that a comparison of pre-operative surgical plan to post-operative CT measurements was performed.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

The document does not provide information on the number of experts used to establish the ground truth for the test set or their specific qualifications. It mentions that the "Surgeon Review Tool (SRT) software is used by surgeons for the review and approval of surgical plans and surgical instrument designs," implying surgeon involvement in the process but not specifically for ground truth establishment for a test set in the regulatory submission context.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

The document does not describe any specific adjudication method (such as 2+1 or 3+1) used for establishing ground truth or evaluating the test set.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

The document does not mention a multi-reader multi-case (MRMC) comparative effectiveness study or any effect size related to human reader improvement with or without AI assistance. The tmCMF Solution is described as a software system for image segmentation, surgical planning, and the production of physical outputs, with the Surgeon Review Tool (SRT) facilitating surgeon review and approval, but not explicitly as an AI assistance tool for human readers in a diagnostic setting that would typically involve a MRMC study.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

While the document describes the tmCMF Solution as a "software system and image segmentation system," it also highlights the "Surgeon Review Tool (SRT) software is used by surgeons for the review and approval of surgical plans and surgical instrument designs" and "Physician Interaction with Planning and Physician Model / Guide Approval." This indicates that the device is intended for human-in-the-loop performance, with the surgeon involved in the review and approval process. A standalone algorithm-only performance is not explicitly described as a primary evaluation method.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

For the "Cadaveric Benchtop Performance Testing," the ground truth was established by "Comparison of pre-operative surgical plan to post-operative CT measurements." This suggests that the ground truth for accuracy was based on direct measurement from CT scans after the surgical plan was implemented on cadavers, rather than expert consensus, pathology, or long-term outcomes data.

8. The sample size for the training set

The document does not provide any information regarding the sample size used for the training set of the tmCMF Solution's "software system and image segmentation system."

9. How the ground truth for the training set was established

The document does not disclose how the ground truth for the training set was established.
