# Manually Correcting a Class II, and Adding Button Cutouts

### Key Steps:


1. **Assess the Situation:**
   * Identify the Bolton discrepancy and determine the need for correction.
   * Check the width of the lateral incisors (<6.4 mm) to confirm the issue.

     
2. **Modify Plan in 3D Controls:**
   * Click on "Modify Plan" and access 3D controls for adjustments.

     
3. **Placing Button Cutouts or Slits:**
   * Preferably place button cutouts on the distal aspect of the tooth to prevent elastic slipping.
   * Attachments should be placed on the tooth to prevent unwanted movement.
   * For lower teeth, place buttons on the first molar. For upper teeth, choose between the canine or first premolar.
   * Consider placing button cutouts on lingual surfaces for crossbite correction if needed.

     
4. **Ensuring Proper Occlusion:**
   * Adjust the position of teeth to achieve even biting between premolars and molars.
   * Use the maintain function to lock teeth and create spacing if necessary for alignment.
   * Ensure a Class I molar and canine occlusion.

     
5. **Building Up Teeth (if needed):**
   * If laterals are smaller, create space around them for build-ups.
   * Discuss options with the patient for aesthetic improvements.

     
6. **Instructions for Technicians:**
   * Request sequential distalization on both sides, moving only two teeth at a time.
   * Start with the second molar, then move the first molar when 50% finished.
   * Progress to the second premolar only after the first and second molars are complete.
   * Move central and lateral incisors as a block unit.
   * Leave space around heavily rotated teeth to prevent friction.

     
7. **Submission for Modification:**
   * Once adjustments are made, submit the plan for modification.

     



Instructions to Technicians:   
  
*Please complete sequential distalization on both sides. Only move two teeth at a time. Begin with the second molar, then when it's 50% finished its movement, start moving the first molar. Only begin moving the second premolar when the second molar is finished moving. Complete this pattern of only moving two teeth at a time for all of the other teeth. The only exception is to move the central and lateral incisors as a block unit.*
