In the beginning everything was developed by attempt and mistakes, all appliances were hand made till the discovery of X-Rays and the Roentgenography. Before the advent of chrome alloy stainless steel , orthodontists had to be skilled craftsman as well as doctors. In fact, much of their time was spent devising, constructing, and maintaining their own oral appliances. Archie Brusse, and those inventive changes were first presented in , in Oklahoma.

Bioprogressive Therapy as an Answer to Orthodontic Needs. Part II
For these and many more reasons "Robert Ricketts" is considered by many "the best orthodontist in the world", and I consider myself fortunate to follow its guidelines and philosophy, which was taught to me by my teachers who had been a student of Ricketts. Below I will briefly explain his 10 philosophical principles. It is not so simple, although it is absolutely viable. Requires full knowledge of the patient's current conditions, conditions that preceded the growth, and the professional must know deeply the specific effects of the treatment. Know the growth and take advantage of this. The opposite can aggravate the treatment. It should be noted that Dr.
Bio-Progressive Therapy, Part 5: Orthopedics in Bio-Progressive Therapy
T he different concepts related to dentofacial orthopedics resulting from application of headgears seem to elicit more controversy than any other area of orthodontics, almost to the extent that each individual orthodontist seems to be able to expound at length on the merits of his or her own unique approach. As practical clinicians, we tend to think of distal headgear traction as useful for anchorage or as a method of correcting Class II malocclusion. As a guide, we faithfully inspect the occlusion of the upper and lower first molars and, when we have reached that ideal of a Class I occlusion, we discontinue the headgear; or perhaps we have the patient wear the headgear as long as we perceive they can tolerate it, then finish the case with Class II elastics. This seems to be the most expedient approach. Any approach to headgear therapy is right if it accomplishes the result we desire for that one individual case.
