Invisalign Mandibular Advancement System: A Modern Approach to Early Jaw Correction
Early orthodontic treatment can play a crucial role in guiding jaw growth and preventing more complex problems later in life. The Invisalign Mandibular Advancement System is a modern solution for children with developing bite issues, offering a comfortable and discreet alternative to traditional functional appliances.
At Cranbourne North Dental, we provide advanced early orthodontic treatment options to help growing patients achieve healthier jaw development, improved bite function, and confident smiles.
What Is the Invisalign Mandibular Advancement System?
The Invisalign Mandibular Advancement System is designed to treat Class II malocclusions, where the upper jaw sits too far forward relative to the lower jaw. This often appears as an overbite and can affect chewing, speech, facial balance, and long-term jaw health.
This system uses custom clear aligners that gently guide the lower jaw forward while also straightening the teeth. Unlike bulky removable plates or fixed metal appliances, Invisalign offers a discreet and digitally planned approach to functional orthodontics for children.
Who Is This Treatment For?
Invisalign Mandibular Advancement is ideal for growing children and early adolescents, typically between 7 and 12 years of age, when jaw growth is still active.
Your child may benefit from early orthodontic intervention 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
Early treatment during growth can often reduce treatment time later and lower the risk of extractions or jaw surgery in adulthood.
How Does Invisalign Mandibular Advancement Work?
The system works through two coordinated processes:
1. Mandibular Advancement
Special features within the aligners guide the lower jaw forward in small, controlled steps, encouraging natural jaw growth into a healthier position.
2. Teeth Straightening
At the same time, the clear aligners gradually align the teeth, allowing jaw correction and orthodontic alignment to occur together.
This dual-action approach makes Invisalign Mandibular Advancement an efficient option for Class II early treatment.
Invisalign Mandibular Advancement with Occlusal Blocks
In addition to the standard precision-wing design, there is now a new version of the Invisalign Mandibular Advancement System that incorporates occlusal blocks, similar in concept to a traditional Twin Block functional appliance.
These occlusal blocks are built directly into the aligners and sit between the upper and lower teeth. Their role is to:
Hold the lower jaw in a forward position more effectively
Improve control of jaw posture during growth
Provide better vertical bite management
Enhance stability during mandibular advancement
This design mimics the proven biomechanics of a Twin Block appliance while retaining the benefits of clear aligner therapy.
Benefits of the Occlusal Block Design
For suitable patients, the occlusal block version offers additional advantages:
More Effective Jaw Positioning
The blocks guide how the teeth contact, helping maintain consistent forward jaw posture.
Improved Growth Guidance
This is particularly helpful for children with more significant Class II discrepancies who need stronger functional correction.
A Twin Block Alternative Without Bulk
Patients receive the benefits of a Twin Block–style appliance without metal components, speech interference, or poor aesthetics.
Still Clear, Removable, and Hygienic
Despite the added blocks, the aligners remain removable, discreet, and easy to clean.
What to Expect During Treatment
At Dental at Keys, treatment begins with a comprehensive orthodontic assessment, including:
Digital 3D scans
Bite and jaw analysis
Growth evaluation
If Invisalign Mandibular Advancement is suitable, a personalised treatment plan is created. Most children wear a series of aligners for 12 to 18 months, with regular reviews to monitor growth and progress.
