When the SUN equals the SUA, it allows the case to be a reciprocal anchorage case; when not, partial or total resistance is needed with space closure in the extraction option (SUA) of the problem. The most common extraction case to camou-flage a dental or skeletal orthodon-tic problem non-surgically remains the bimaxillary protrusion. 12 tioners would be on a supportive orthodontic foundation to read and study the newly published Andrews textbook: The Six Elements of Orthodontic Philosophy: Goals, Diagnosis, Classification, and Treat-ment. 14 7.

Conclusion The Andrews Extraction Classifi-cation of Treatment System and accompanying Fully-Programmed Advanced Brackets using the Andrews SW Methodology allows the clinician to deliver quality and sufficiency of orthodontic treat-ment. In the words of Andrews, “it baffles me why everyone doesn’t use a fully programmed appliance.” The American Orthodontic Soci-ety has adopted the Andrews Static Six Keys to Optimal Occlusion and the Roth functional mutual protec-tive scheme of occlusion as a portion for the AOS Academy of Diplomates Credential Exam. 13 Second generation SW practi-26 Spring 2026 JAOS
