Mastering the PIR Protocol: My Sequential Approach to Class II Division 2 Treatment
Class II Division 2 malocclusion is complex, with retroclined incisors, deep bite, and vertical challenges. The PIR protocol—Procline, Intrude, Retract—offers a clear sequence to manage these cases with stability and precision. Read how to optimize biomechanics, avoid pitfalls, and achieve predictable long-term outcomes.


Improving Molar Rotation with a Dual Attachment Strategy
Molar rotation with aligners is tough—size and roots make movement unpredictable. Dual attachments, placed buccally and lingually, create a couple force for pure rotation and better control. With precise planning and placement, this method reduces auxiliaries and improves predictability in rotations over 10°.
