Do Candid Pro aligners cause posterior open bites?
Answer: Posterior open bites can be a concern in aligner therapy, but understanding the causes and prevention methods is crucial. Here’s an in-depth explanation:
- Historical Context:
- Early Challenges: Early in the use of aligner therapy posterior open bites were a common issue.
- Learning Curve: Through experience and advancements, the industry has learned how to better prevent this problem.
- CandidPro's Approach:
- Case Setup: The primary factor in preventing posterior open bites is how the cases are set up. CandidPro has refined this process to minimize the risk.
- Causes of Posterior Open Bites:
- Anterior Premature Contact: Almost every posterior open bite case is due to anterior premature contact, typically between the canines (6 to 11) or the anterior teeth (22 to 27).
- Mandibular Release: When expanding the upper arch, the lower mandible tends to move forward. Insufficient overjet can result in a posterior open bite if this forward release is not anticipated.
- Prevention Strategies:
- Overjet Planning: Ensure sufficient overjet in the treatment plan:
- Anterior Overjet: No less than 0.5 millimeters and up to 1 millimeter.
- Canine Overjet: Around 0.2 to 0.3 millimeters.
- Allow for Mandibular Movement: By planning for potential mandibular forward movement, we can prevent the development of posterior open bites.
- Overjet Planning: Ensure sufficient overjet in the treatment plan:
- Benefits of Proper Planning:
- Refinement Ease: If the mandible does not move as anticipated, it is easier to reduce a slight overjet through refinements than to correct a posterior open bite.
- Patient Satisfaction: Proper case setup leads to better outcomes and happier patients.
By carefully setting up cases and anticipating mandibular movement, CandidPro aligners can effectively prevent posterior open bites, ensuring smoother and more successful treatments.
