The Invisalign volume-based tier designations (e.g. Platinum Elite (PE), Platinum (P), Diamond (D) and Black Diamond (BD) are based on the number of historical Invisalign cases that a provider has submitted over a defined period of time. The tier system does not represent a doctor’s clinical experience or clinical skills in orthodontic treatment. The Invisalign provider tier level designations are not recognised as specialty areas by any applicable dental associations and have no relevance to a practitioner’s dental or orthodontic skill, or a particular treatment outcome. An Invisalign provider’s Invisalign volume-based tier designation is simply a tool that a patient can use for considering a practitioner’s experience with Invisalign treatment. You should always make your own judgement in selecting a practice and provider to start your Invisalign treatment. It should also be noted that the clinical outcome from Invisalign treatment to is based on a lot of different factors that can include the condition of your teeth, compliance, the treatment plan, and the doctor’s orthodontic experience.
