When most people think of orthodontics, they immediately envision rows of metal or ceramic brackets. However, as a specialist with over 25 years of experience, I view braces as just one set of tools in a much larger kit. To achieve a truly Healthy Functional Bite, we must often address the relationship between the upper and lower jaws - the “foundation” of the smile.
When the teeth are relatively straight but the jaws don’t align correctly, we utilize functional appliances. These devices are the “hardware” upgrades that allow us to guide growth and correct bites with clinical precision.
Correcting the “Overbite”: The Herbst and Forsus Appliances
One of the most common challenges we face is a Class II malocclusion, where the lower jaw sits too far behind the upper jaw. In a growing patient, we can use fixed functional appliances to encourage the lower jaw to develop into a more forward, healthy position.
The Herbst Appliance: This is a highly effective, time-tested device that is bonded to the molars. It uses a telescoping mechanism - similar to a piston - to hold the lower jaw forward. Because it is fixed in the mouth, it works 24/7 without requiring the patient to remember to wear elastics. It is a masterpiece of digital innovation and mechanical engineering that helps avoid the need for jaw surgery later in life.
The Forsus Fatigue Resistant Device: Often used in conjunction with braces, the Forsus appliance uses a specialized spring module. It applies a continuous, light force to move the upper teeth back and the lower teeth forward. It is a more streamlined alternative to the Herbst and is excellent for fine-tuning the bite during the later stages of treatment.
Widening the Horizon: Palatal Expanders
As discussed in our comprehensive approach to Phase 1 treatment, the Palatal Expander is used when the upper jaw is too narrow. By gently widening the two halves of the upper jaw before they fuse, we create the necessary space for permanent teeth and correct crossbites. This not only improves the “fit” of the teeth but can also have positive effects on the nasal airway, supporting better systemic health and breathing.
The Role of TADs (Temporary Anchorage Devices)
In the past, complex tooth movements often required the use of external “headgear.” Today, we utilize digital technology to place TADs - tiny, temporary titanium pins that act as fixed anchor points in the bone. These allow us to move specific teeth in ways that were previously impossible without surgery. They provide a level of customization and control that ensures predictable, stable results even in the most nuanced cases.
Why the “Specialist” Perspective Matters
Choosing the right appliance is a matter of meticulous clinical diagnosis. At Fine Orthodontist, we don’t just “straighten teeth”; we engineer a functional system where the muscles, joints, and teeth work in perfect harmony. Whether we are using the FineLine Aligner System or a complex functional appliance like the Herbst, every decision is evidence-based and tailored to the patient’s long-term health.
