코멘트
- This is a very severe deep bite Class II div 2 case.
- 18 was extracted to ensure that UR distalization could be performed smoothly.
- The lower anterior intrusion was done successfully to level the lower arch Curve of Spee and resolve deep bite problem. Sequential intrusion protocol was used to perform lower anterior intrusion.
- 26 full zirconia crown was fabricated after aligner treatment.
- Both upper and lower esthetic crown lengthening was performed to increase clinical crown for better smile pattern.
