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 aligner trays and aligners, based on 3D models of the patient’s dentition before the start of an orthodontic 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 user to have 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.

Indications for use as stated in the FDA summary.
