Device Story

HDH Treatment Planning System is a software-based tool for dental professionals; imports 3D digital scans of patient dentition (from intra-oral scans or analog impressions); enables systematic inspection, measurement, and simulation of tooth movements; allows virtual design of dental casts for sequential aligner trays or retainers. Output is exported as STL or OBJ files for fabrication. Used in clinical settings by orthodontists/dental professionals; assists in developing virtual treatment plans; facilitates orthodontic diagnosis and treatment simulation; benefits patients by enabling customized, sequential orthodontic appliance design.

Clinical Evidence

No clinical data performed; bench testing only. Software verification and validation testing conducted per FDA guidance; all results met acceptance criteria.

Technological Characteristics

Software-based device programmed in C++. Hardware requirements: Windows 8/10 (64-bit), >=8GB RAM, >=1GB video memory, 10GB HDD, Intel Core i5 2500 or equivalent, network connection.

### Table 1. Predicate Device Information Comparison

{6}------------------------------------------------

{7}------------------------------------------------

The software output for the predicate device is represented by custom metal bands, indirect bonding transfer trays and dental casts, whereas the subject device designs only dental casts.

### Clinical Testing:

Clinical testing is not a requirement and has not been performed.

## Substantial Equivalence Conclusion:

By definition, a device is substantially equivalent when the device has the same intended use and the same technological characteristics as the predicate device. The subject and the primary predicate devices share intended use including software used by dental professionals in orthodontic treatment planning for management of patients and orthodontic models, inspection, measurement and analysis of the models, treatment simulation, preparation and export of a series of virtual dental casts. The subject and the primary predicate devices share the same operating principle.

The software output for the predicate device is represented by custom metal bands, indirect bonding transfer trays and dental casts, whereas the subject device designs only dental casts. The difference in the software output along with the supported types of digital data is insignificant and do not require further testing to ensure the correct product operation; thus, the difference does not affect safety or efficacy of the subject device.

The subject and predicate devices share digital imaging tools based on 3D orthodontic models for orthodontic case archiving, diagnosis, treatment planning and CAD design, and virtual planning of orthodontic treatments simulating tooth movements.

Performance data demonstrates that any differences in technological characteristics do not raise different questions of safety or effectiveness.

The conclusion drawn from the data included in this submission demonstrates that the HDH Treatment Planning system is substantially equivalent to the cleared predicate device.
