Methods and systems for diagnosing and identifying a treatment for an orthodontic condition can include a server configured to receive patient data through a website. Methods and systems can include the use of a database that includes or has access to information derived from textbooks and scientific literature and dynamic results derived from ongoing and completed patient treatments. Methods and systems can include the operation of at least one computer program within the server, which can be capable of analyzing patient data and identifying at least one diagnosis of an orthodontic condition. Methods and systems can include assigning a probability value to at least one diagnosis, and the probability value can represent a likelihood that a diagnosis is accurate. Methods and systems can include instructing a computer program to identify at least one treatment approach, a corrective appliance, or a combination thereof for the at least one diagnosis.
