Invisalign Mandibular Advancement System: Early Jaw Correction for Growing Smiles
Early orthodontic treatment can have a lasting impact on your child’s bite, jaw development, and facial balance. The Invisalign Mandibular Advancement System is a modern solution for children with developing overbites, offering a comfortable and discreet alternative to traditional functional appliances.
At Dental at Keys, we provide advanced early orthodontic intervention to guide jaw growth and reduce the need for complex treatment later in life.
What Is Invisalign Mandibular Advancement?
This treatment is most effective for growing children aged 9 to 14, when jaw growth is still active.
Your child may benefit if they have:
A noticeable overbite
A small or retrusive lower jaw
Difficulty biting or chewing
Crowded or misaligned teeth
Early signs of jaw imbalance
Treating these issues early can reduce treatment time later and lower the risk of extractions or jaw surgery.
How Does It Work?
Invisalign Mandibular Advancement works in two ways at the same time:
Jaw Advancement
Special features in the aligners guide the lower jaw forward in small, controlled steps, encouraging healthier jaw growth. This is known as functional therapy.
Teeth Straightening
At the same time, the aligners gradually move the teeth into better alignment.
This dual approach makes it an efficient option for Class II early treatment.
Invisalign with Occlusal Blocks (Twin Block–Style Design)
There is now a new version of Invisalign Mandibular Advancement that includes occlusal blocks, similar in concept to a traditional Twin Block functional appliance.
These occlusal blocks are built into the aligners and sit between the upper and lower teeth. They help to:
Hold the lower jaw in a forward position more effectively
Improve control of jaw posture during growth
Provide better vertical bite management
Increase stability during treatment
This design offers the biomechanics of a Twin Block appliance with the benefits of clear aligner therapy, making it an excellent Twin Block alternative for suitable patients.
If you are concerned about your child’s overbite or jaw growth, early advice is invaluable. The Invisalign Mandibular Advancement System, including the newer occlusal block design, offers a modern and effective approach to early jaw correction.
