1 Engineering Your Invisalign Treatment Plan To Conquer a Wide Variety of Cases Dr. Willy Dayan Orthodontics is not just Straight Teeth Skeletal Foundation Posterior Interdigitation Anterior Guidance Transverse Relations Vertical Dimension of Occlusion Lip Support Lip Competency Neutral Zone Straight Teeth Smile Lines Comprehensive Orthodontic Diagnosis Align upper and lower arches is not a treatment plan! 4 2 Dr. Willy Dayan DDS ( 1986) and Diploma of Orthodontics from the University of Toronto (1991) Orthodontic practice in Toronto, Canada, focused on Cosmetic and Rehabilitative Orthodontics. Invisalign Super Elite Provider and member of the Aligntech Institute Faculty Lecturer at the University of Toronto, and Guest Lecturer at Tel Aviv University and Hadassah University in Jerusalem Featured speaker at the Pankey Institute, Invisalign Forum and Invisalign Summits, and numerous Align events worldwide. Member of the AAO and CAO, and other dental organizations Married to Ellen Dayan ( Restorative Dentist ), and 4 great children, Laurel, Ariel, Jamie, and Jory Intra-orally Extra-orally Should these people get the same treatment plan and same retainers? Customize our retention the way we customize our treatment plan! Biological Variation! Engineering Your Invisalign Treatment Plan To Conquer a Wide Variety of Cases Outline 1) Diagnosis and Treatment Plan...It Still Matters 2) Understanding Bio-mechanics of Invisalign 3) They are All Invisalign Cases! 6 Orthodontics is not just Straight Teeth Skeletal Foundation Posterior Interdigitation Anterior Guidance Transverse Relations Vertical Dimension of Occlusion Lip Support Lip Competency Neutral Zone Straight Teeth Smile Lines Comprehensive Orthodontic Diagnosis Align upper and lower arches is not a treatment plan! Who is the clinician and who is the technician. Doctor your ClinCheck!

2 Engineering Your Invisalign Treatment Plan To Conquer a Wide Variety of Cases Outline Upper Lateral Incisor Bodily Movement Need 2 points of contact to create a rotational moment. 1) Diagnosis and Treatment Plan...It Still Matters 2) Understanding Bio-mechanics of Invisalign 3) They are All Invisalign Cases! 10 A Review of Bio-Mechanics of Invisalign! Translating Roots Mesially or Distally Willy s Golden Rules of ClinCheck Analysis Controlling Root Tipping. 1) Think Like Plastic and Feel Like a Tooth. 2) Stop watching the video as teeth moving, but think of it as aligners surfaces changing. Focus on the correction of LL2 and LR2 Some Clinical Examples 11 Levelling Deep Curve of Spee Translating Roots Mesially or Distally What the tooth needs to feel, and what we need to see! What if the bicuspids have optimized rotation attachments?!?! 9 12

3 Translating Roots Mesially or Distally Opening Space for a Missing Maxillary Lateral Incisor I tried that and it did not work, so my conclusion could be... Invisalign can t do that!!! But is that true? cc1 Go To ClinCheck 1 A ClinCheck Treatment Plan after the first plan did not work! Progress Xrays cc2 Go To ClinCheck 2 ( instructed by orthoclined.com ) Not finished yet Conclusion: Ask not what Invisalign can do. but ask yourself what you can do with Invisalign!!!

5 Bite Turbos: Incisors or Cuspids? Vertical Challenges Deep-bite and Openbite The idea is to have the ledges act as a removable anterior bite plane to avoid excessive posterior contact of upper and lower aligners. Go to Cuspid Turbos Clincheck The reality of too much overjet allows mandible to close distal to ledges. Assessing The Vertical Dimension of Occlusion Bite Turbos: Incisors or Cuspids? The idea is to have the ledges act as a removable anterior bite plane to avoid excessive posterior contact of upper and lower aligners. Go to Cuspid Turbos Clincheck The reality of too much overjet allows mandible to close distal to ledges. What does it tell you about the forces on the teeth that have created this equilibrium? Bite Turbos: Incisors or Cuspids? Vertical Challenges: Deep Anterior Overbite The idea is to have the ledges act as a removable anterior bite plane to avoid excessive posterior contact of upper and lower aligners. ClinCheck is not teeth moving, but the force system to get them there. 30
