What is it indicated for?
CS Model+ is intended for use as a front-end software tool for management of orthodontic models, detailed analysis, treatment simulation and virtual appliance design options, including dental casts and orthodontic appliances. These applications are 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 the treatment. It can be used at the end of the treatment to evaluate if the outcome is consistent with the planned/desired treatment objectives.
The use of CS Model+ requires the user to have the necessary training and domain knowledge in the practice of orthodontics.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
