A student of Cephalometrics, Dr. Beistle has developed and promoted the use of Sassouni-Plus analysis along with the concept that that maxilla is the modern-day “diagnostic arch.” Dr. Beistle believes that the “condition ” of the maxilla (including the maxillary dentition) is the key to facial esthetics and TMJ integrity. He should be considered a conservative in the area of extraction believing that most crowding is “illusionary” caused by dental arch constriction, lingualversion of the dentition and an over-closed vertical dimension.
