Adult Anterior Growth Appliances and Orthodontic Expanders
Welcome to the TMJ Sleep and Breathe Center in northern Virginia. Our patients are adults who have painful symptoms in their jaw, neck and back. Most also variably clench their teeth, have sleep problems and teeth that are not aligned. The structural cause to these problems is inadequate space and balance in the jaws and airways. At least that is how it starts out. Our practice integrates adult palate expanders, posture correction, breathing exercises and myofunctional therapy. Our treatments help people smile, bite, breathe, sleep and posture better. Our therapy can eliminate the need for night guards, bite splints and CPAP and mouth breathing habits forever.
Adult Palatal Expander Options:
No one appliance or treatment is the best for every case. Every patient is different and needs to be individually diagnosed. We design treatment plans and appliances depending on the diagnosis and the specific needs of each patient. For example a patient with severe sleep apnea will be treated differently than someone with only jaw pain and head aches.
Our Treatment Modalities:
- Adult palate expander appliances
- Myofunctional tongue therapy
- Breathing exercises
- Posture restoration therapy.
- Alleviate TMJ pain and headaches
- Restore healthy breathing patterns
- Decrease airway resistance
- Balance the bite
- Improve posture
- Balance upper and lower jaw relationships
- Correct tongue function
The DNA Appliance:
The DNA appliance was originally invented by Dr. Singh. The technology has since been purchased by Vivoslife.com The DNA has a sister appliance called the mRNA appliance which is a combination of a DNA appliance with a standard mandibular repositioning feature. The DNA device is perhaps the most versatile of the adult expanders. It is probably the most comfortable appliance among the adult appliances.
The Homeoblock Appliance:
The Homeoblock appliance was invented by Dr. Belfor and is exclusively for adults. The device is an anterior growth appliance that works by stimulating bone growth with a unilateral bite block. The theory is everyone has one side of their face that is under developed more than the other. The bite block is placed on the weaker side and stimulates bone to grow to start growing. The Homeoblock is custom designed to address the individual needs of each patient. The device is highly customizable and versatile. The Homeoblock is very similar to the DNA appliance, but may be better in cases where there are more facial asymmetries and cranial strains. The DNA and Homeoblock appliances are both adapted Schwarz devices with a special spring and bite plane area.
The ALF Appliance:
The ALF appliance is the “advanced lightwire functional.” It is a light gauge wire that is very flexible and springy. The ALF typically stays in the mouth all the time and is not removed by the patient. It puts a constant outward springy pressure and its growth potential is aided by tongue movement. The tongue pushes on the device and creates an increase in expansive pressure during swallowing and talking. The ALF is custom made to fit around teeth in narrow spaces. The device is especially helpful when there is severe crowding because it is so small. The ALF results in a decent amount of teeth movement and will usually need to be followed by conventional braces or Invisalign.
The Crozat Appliance
The Crozat appliance looks similar to the ALF but it works a bit differently. The Crozat is better at expanding the posterior palate than the ALF. The ALF is better at expanding the anterior part of the maxilla than the Crozat. The Crozat wire is typically a heavier gauge than the ALF. The wire crosses across the back part of the palate whereas the ALF passes behind the front part of the mouth. The Crozat like the ALF uses tongue pressure and function to promote jaw development.
What are Palatal Expanders?
We prefer the use of the term “growth appliances.” They are small retainer-like devices that promote growth of the jaws. The goal is to grow the jaws into a more optimal size and shape. Teeth will have space to fit. The tongue will have room to move freely. And air will pass without resistance between the nose, mouth and lungs. Growth appliances work by applying a light force in the direction the jaws need to grow. They are not mechanical devices and do not cause pain. The appliance mimics tongue pressure and encourages proper tongue position. Appliance therapy is synergistic with swallowing and tongue movement. Most kids only need to wear the appliances at night for 6-9 months during treatment. The appliances are usually not worn during the day or while eating.
Does Palate Expansion Work for Adults?
Yes. Light and flexible springs on adult expansion appliances increases bone cell activity and makes expansion possible for many adults. Growth is a lot slower in adults vs kids, but it does work. There is more to it than “expansion” though. Small changes in upper and lower jaw positions makes a big improvement in tongue position, posture and airway resistance.
Palatal Expanders Compared to Braces
Braces are for straightening teeth. Growth appliances grow the jaws to be a more optimal size and shape. Optimal treatment is to first grow the jaws to be the correct size and shape. And then straighten the teeth and balance the bite. Many times during expansion, the teeth will naturally get straighter and less crowded and crooked. Sometimes orthodontics is necessary after expanders, whereas in others, an acceptable cosmetic result can be obtained with expanders alone.
Removable vs Fixed Adult Expanders
Some orthodontic growth appliances stay in the mouth all the time hence the term “fixed.” Other appliances are removable and can be taken out of the mouth by the patient. Removable appliances are more comfortable because they do not get in your way while talking or eating. They are usually only worn at night time. Also, it is not always good to have an appliance in the way of normal forces places on teeth top to bottom. Biting pressure on the teeth keeps the upper a lower jaw bones in sync. The ALF and the Crozat are fixed appliances whereas the Homeoblock and DNA appliances are removable.
