The summary describes software for treatment planning and design based on clinician input and scans, and the aligners themselves. There is no mention of AI or ML in the device description, intended use, or performance studies. The "Mentions AI, DNN, or ML" field is explicitly marked as "Not Found".
No
The Blue Sky Plan Software is a medical front-end device for managing orthodontic models, analysis, and treatment simulation. The Blue Sky Bio Aligners are a series of clear plastic appliances for treating tooth malocclusions, indicating they are the therapeutic devices, while the software supports their design and use.
Yes
The "Intended Use / Indications for Use" section explicitly states that the Blue Sky Plan Software is a "medical front-end device providing tools for ... systematic inspection, detailed analysis, treatment simulation..." These are all functions characteristic of a diagnostic device, as they involve analyzing patient data to understand their condition and plan treatment.
No
The device description clearly states that the submission includes both the Blue Sky Plan Software and the Blue Sky Bio Aligners (Z and Z FLX), which are physical aligner trays made of thermoplastic material. The performance studies also include testing on the physical aligner materials (biocompatibility and ASTM D638). Therefore, it is not a software-only medical device.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Device Function: The Blue Sky Plan Software and Blue Sky Bio Aligners are used for the planning and execution of orthodontic treatment based on 3D models of the patient's teeth. They are not used to analyze biological specimens from the patient's body.
- Intended Use: The intended use clearly describes the software's role in managing orthodontic models, analysis, treatment simulation, and virtual design of aligners. The aligners are physical devices used to move teeth.
- Device Description: The description focuses on the process of using digital models of teeth to design and fabricate physical aligners.
The device is a medical device used for treatment planning and delivery in orthodontics, but it does not fit the definition of an In Vitro Diagnostic.

Intended Use / Indications for Use
Blue Sky Plan Software orthodontic module is intended for use as a medical front-end device providing tools for management of orthodontic models, systematic inspection, detailed analysis, treatment simulation and virtual design of a series of dental casts which may be used for sequential aligners, based on 3D models of the patient's dentition before the start of an orthodonic treatment. It can also be applied during the treatment to inspect and analyze the progress of treatment, and at the end of treatment to evaluate if the outcome is consistent with the planned/desired treatment objectives.
Blue Sky Bio Aligner Z and Blue Sky Bio Aligner Z FLX are series of clear, lightweight, plastic appliances indicated for the treatment of tooth malocclusions in patients with permanent dentition (i.e. all second molars). Utilizing a series of incremental tooth movements, it sequentially positions teeth by way of continuous force.
The use of the Blue Sky Plan Software module requires the necessary training and domain knowledge in the practice of orthodontics, as well as to have received a dedicated training in the use of the software.

Device Description
A dental clinician, using a standard personal computer prescribes the orthodontic appliance based on an assessment of the patient's teeth and determines the course of treatment using the Blue Sky Plan Software. The clinician takes molds of the patient's teeth and completes a prescription form and sends the molds to the dental lab, which in turn scans the molds and uploads the .STL files of the molds in Blue Sky Plan software. This digital file is a series of CAD files (.STL) for building models that can be used to fabricate the aligners. Alternatively, the dental clinician may generate the digital files by scanning the patient's mouth directly, using an intraoral scanner, and then send the files to the dental lab.
The Blue Sky Bio Aligners (Z and Z FLX) consist of a series of clear plastic aligner trays which are fabricated with the selected thermoplastic material (either a thin polyurethane sheet or a composite of copolyester and polyurethane). Both materials are commercially used for thermoforming customized removable aligners for the intended use.
The prescribing physician reviews and approves the model scheme before the aligners are produced. Once approved by the clinician, the dental lab produces the Blue Sky Bio Aligner Z or Z FLX.
The finished aligners are sent to the dental clinician who then provides them to the patient, confirming fit and form. Over a period of time, additional aligner trays are provided sequentially to the patient by the clinician to gradually move the target teeth to the designed position. The dental clinician monitors treatment from delivery of the first aligner to the final aligner.
The trays are held in place by pressure and can be removed by the patient at any time.

Comparison to Predicate and Reference Devices:
The similarities in intended use and technological characteristics comparing the subject Blue Sky Plan Software and Blue Sky Bio Z and Z FLX aligners to the Predicates follow:
- The software has the same intended use as the Primary ● Predicate and functions similarly as noted.
- The aligners are clear plastic, customized sequential ● aligners with the same intended use and mechanism of action as the Secondary Predicate and Reference K180107:
- They are intended for realignment of teeth during . orthodontic treatment of malocclusions by way of continuous gentle force.
- They use the same thermoplastic materials as the ● Secondary Predicate.
- . They are thermoformed using similar processes as the Secondary Predicate and using the same processes as the Reference Device (K180107).
The subject device software and the Primary Predicate software have proprietary differences, but they have the same intended use and function equivalently. Furthermore, both Reference devices use the same software.
The only differences between the subject device aligners and the Secondary Predicate are the minor proprietary differences in the processes; those processes are standard in this field for thermoforming/manufacturing clear aligners. Furthermore they are the same processes used for Reference aligner K180107.
Details follow on the Substantial Equivalence Comparison Tables (Table A for the PNN code; and Table B for NXC code).
Based on the documentation presented in the 510(k), as Substantial summarized herein, it can be concluded that these clear aligner Equivalence systems are substantially equivalent to the Predicate devices. Conclusion:
