History

 

1960-1970: THE SIX KEYS TO OPTIMAL OCCLUSION, OPTIMAL OCCLUSION© TOOTH MEASUREMENT FINDINGS, AND THE ANDREWS2 STRAIGHT-WIRE APPLIANCE

 

Lawrence F. Andrews, D.D.S., has engaged in independent research, teaching, and publishing since 1960. Research spanning ten years led to the Six Keys to Optimal Occlusion, quantifying the tooth positions of naturally optimal dentitions, and the Andrews2 Straight-Wire Appliance. This information has been documented in a text titled, “Straight-Wire, The Concept and Appliance” (L. A. Wells, 1989). By 1980, all had gained worldwide acceptance.

 

1980-1998: THE SIX ELEMENTS OF OROFACIAL HARMONY AND THE ANDREWS ARTICULATOR SYSTEM

 

1980's - 1990's research led to finding the Six Elements of Orofacial Harmony. They are the characteristics found to be shared by individuals with both optimal occlusion and balanced faces. They are proposed as optimal goals for orthodontic treatment and as the bases for a new positionally correct classification system. This body of work has been presented in meetings and courses in the Americas, Europe, and Asia since 1990. 1980's research also led to a new articulator system, designed specifically for the needs of orthodontists. It is called the Andrews Articulator System. The system is now available from Golden Eagle Orthodontics, Inc. (website: http://www.geo-orthodontics.com).

 

Directors

 

Will A. Andrews, D.D.S. joined the Foundation in 1992 and is co-director with his father. Will has an active orthodontic practice and is involved in research and teaching.
