Ricektts edgewise was the background, sufficient departure from traditional edgewise therapy has been made to warrant a new label, “”bioprogressive therapy. Anchor teeth are stabilized against cortical bone; hence, cortical anchorage. It is difficult to appreciate these views and practices in the beginning because the method may be difficult to envision on the typodont or as simply a laboratory mechanical exercise due to the fact that cortical bone, growth, and muscle are not present in an artificial medium.

Accordingly, in order for the clinician to apply the new technique with the intelligence, he must realize that many biologic factors form the fundamental criteria of its application.


Bioprogressive therapy as an answer to orthodontic needs. Part II.

We have attempted to examine these factors and place them in their appropriate hierarchy of significance. In order to fully apply the recommendations of the proponents ricketta this method, mechanical forecasting, physiologic forecasting, and growth forecasting principles are all employed. Soldering of auxiliaries has been eliminated, as well as the heat treating of wires.

Even as a simple mechanical regime, however, it rates with or better than any other current multibanded method as a practical and efficient clinical procedure. The technique usually involves orthopedic correction, particularly in the maxilla, when such corrections are needed A limited use of round biopdogressive is employed with this technique except for specific isolated conditions in which there is a place for tipping or simple alignment and rotation of teeth.

Used as a triple-control technique, the rricketts method excels in proper overtreatment and for delivery of anchorage.

Loops or forms are bent in the wire for lighter and more continuous pressures on teeth to be moved. A continuous arch is broken up into segments so that movements in desired planes of space are not complicated and anchorage can be shifted in favor of the desired move. We try to avoid leveling with round wires, for reasons that have been explained.


Eight steps usually form the frame of reference. Ironically, it can be applied in the very young and in the very old. From the foregoing discussions, it may be recognized that a new, lighter, and sequential order of force applications is recommended. In order to position and control the teeth behind or bioprogreasive from cortical bone or against or bioprogreswive from muscle or to intrude into or extrude away from the bony alveolus, three-plane control is utilized.
