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

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. The technique usually involves orthopedic correction, particularly in the maxilla, when such corrections are needed Eight steps usually form the frame of reference. Used as a triple-control technique, the bioprogressive method excels in proper overtreatment and for delivery of anchorage.

From the foregoing discussions, it may be recognized that a new, lighter, and sequential order of force applications is recommended.

We try to avoid leveling with round wires, for reasons that have been explained. Anchor teeth are stabilized against cortical bone; hence, cortical anchorage. A limited use of round wire is employed with this technique except for specific isolated conditions in which rricketts is a place for tipping or simple alignment and rotation of teeth.

It is difficult to appreciate these views and practices in the bioprogrezsive 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. Ironically, it can be applied in the very young and in the very old. We have attempted to examine these factors and place them in their appropriate hierarchy of significance.

Soldering of auxiliaries has been eliminated, as well as the heat treating of wires. In order to fully apply the recommendations of the proponents of this method, mechanical forecasting, physiologic forecasting, and growth forecasting principles are all employed.


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

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. In order to position and control bioprobressive teeth behind or away from cortical bone or against or away from muscle or to intrude into or extrude away from the bony alveolus, three-plane control is utilized.

While edgewise was the background, sufficient departure from traditional edgewise therapy has been made to warrant a new label, “”bioprogressive therapy. Loops or forms are bent in the wire for lighter and more continuous pressures on teeth to be moved.
