Whenever we bite down, we’re applying force with our jaw muscles. Functional appliances direct these forces to create healthier tooth and jaw alignment. They’re used to help correct bite problems and to encourage symmetrical jaw growth.

Functional appliances aren’t always necessary. Because every child’s teeth and bite are different, orthodontic treatment at our Mesa office is carefully tailored to your child’s individual needs.

• For the child with minor tooth misalignment, traditional braces or aligners might be all that’s needed.
• For the child with a minor malocclusion, or bite problem, an orthodontist might use elastics (rubber bands) to bring teeth into healthy alignment.
• For the child who has a more serious malocclusion, involving both tooth and jaw alignment, an orthodontist might recommend a functional appliance.

A severe Class II malocclusion can be caused when the upper jaw or teeth are positioned too far forward, and/or the lower jaw is too small or positioned too far back. Common Class II malocclusions include:

• Open bite—the front teeth don’t touch when the back teeth bite down, or the back teeth don’t touch when the front teeth close.
• Overbite—some overbite is normal. A deep overbite occurs when the upper teeth significantly overlap the lower teeth.
• Overjet—the upper front teeth protrude further horizontally than they should.

Today’s functional appliances come in a variety of designs to treat Class II malocclusions. They can be fixed or removable. They can be used with or without braces. Some are designed to expand the upper palate to make sure there’s room for all the permanent teeth. What they all do is advance the position of the lower teeth and jaw to create a healthier, more comfortable bite.

Fixed devices are attached to the teeth and meant to be used full-time. These include the Forsus™ device, the Herbst® appliance, and the MARA appliance.

• Forsus Device

This appliance works with braces. A spring coil rod is most often attached to bands on the first molars on the upper jaw. It’s then connected to the arch wire on the lower jaw. Just like elastics—but more effective!—these spring coil rods provide gentle forward pressure that encourages the lower jaw and teeth forward.  

• Herbst Appliance

The Herbst appliance also applies forward pressure to the lower jaw using telescoping rods connecting the upper and lower teeth. The rods expand as the mouth opens, and telescope together as it closes, positioning the lower jaw further forward while the upper jaw is held back. The Herbst can be worn alone or with braces, and can also be used to expand the upper palate.

• MARA Appliance

The MARA (Mandibular Anterior Repositioning Appliance) uses an adjustable “elbow” piece connecting bands on upper and lower molars to guide the lower jaw and teeth forward when the jaw closes.

Removable appliances such as Bionator and Twin Block appliances can also improve Class II malocclusions. They are meant to be worn for a specific number of hours each day, and can be taken out for sports or other activities as needed. Because it’s essential to get all the necessary hours in, removable appliances require commitment!

• Bionators

A bionator is made of wire and acrylic, and it looks a lot like a retainer. The wire fits around the upper front teeth. It’s attached to a smooth piece of acrylic that sits behind the upper teeth and is shaped to guide the lower jaw forward when biting down. The bionator can also be adjusted to expand the upper palate.

• Twin Block Appliance

The twin block appliance uses two separate pieces made of wire and smooth acrylic. Both pieces are modeled to fit precisely over the upper and lower arches. The acrylic “blocks” fit over the biting surfaces of the teeth, working together like a 3D puzzle. When your child bites down, the upper blocks slide into place behind the lower blocks, pushing the lower jaw and teeth forward. The top plate can also be adjusted to expand the upper palate if needed.

Because these appliances are best used while a child’s bones are still growing and developing, dentists and orthodontists recommend an orthodontic evaluation by age seven. Early treatment with a functional appliance can help correct serious bite problems before or together with braces. In some cases, functional appliances may reduce the need for headgear or surgery.

Todays’ orthodontic technology has made functional appliances more comfortable and efficient than ever before. Talk to Dr. Nathan R. Yetter to discover how an individualized treatment plan and a custom appliance can give your child a healthy bite and a lasting smile.

Every year, Americans all over the world celebrate the birth of the country and its independence on the Fourth of July. There are countless ways that people celebrate and they range from community parades and large scale gatherings to concerts, fireworks displays, and smaller scale celebrations among family and friends. For some people, July 4th is synonymous with baseball, while for others it is all about the beach of barbecues. However you celebrate, you can be sure that red, white, and blue is visible everywhere throughout the area.

The Beginnings of Fourth of July Celebrations

Although it wasn't officially designated as a federal holiday until 1941, the actual tradition of celebrating Independence Day goes back to the time of the American Revolution (1775 – 1783). At the time of the American Revolution, representatives from the 13 colonies penned the resolution that ultimately declared their independence from Great Britain. The continental congress voted to adopt the Declaration of Independence on July 2nd of 1776. Two days later, Thomas Jefferson's famous document that is now known as the Declaration of Independence, was adopted by delegates representing the 13 colonies.

First States to Recognize the Fourth of July

In 1781, Massachusetts became the first state (or commonwealth) whose legislature resolved to designate July 4th as the date on which to celebrate the country's independence. Two years later, Boston became the first city to make an official designation to honor the country's birth with a holiday on July 4th. In that same year, North Carolina's governor, Alexander Martin, became the first governor to issue an official state order stipulating that July 4th was the day on which North Carolinians would celebrate the country's independence.

Fun Facts About the Fourth of July

• The reason the stars on the original flag were arranged in a circle is because it was believed that would indicate that all of the colonies were equal.
• Americans eat over 150 million hot dogs on July 4th.
• Imports of fireworks each year totals over $211 million.
• The first “official” Fourth of July party took place at the White House in 1801.
• Benjamin Franklin didn't want the national bird to be the bald eagle. He believed that the turkey was better suited to the coveted distinction. John Adams and Thomas Jefferson disagreed with him, and he was outvoted, so the bald eagle became the official bird of the United States.

For many, the tradition is something entirely different. Along the coastal areas of the United States, people may haul out huge pots to have lobster or other types of seafood boils. Others may spend the day in the bleachers at a baseball game, or at a park, cooking a great traditional meal over an open fire. No matter how or where you celebrate, one thing is certain: all Americans celebrate July 4th as the birth and independence of our country.

Dr. Nathan R. Yetter and our team at East Valley Orthodontics wish you a safe and happy Fourth of July!

Parents want the best for their teens and often ask us about the perks of Invisalign Teen clear aligners compared to traditional braces. Invisalign treatment is a style of braces that skips the usual metal and wires, and uses a clear, thermoplastic material to create removable aligners instead.

Aligners are custom-made for each patient and replaced every two weeks to attain gradually straighter teeth.

Is Invisalign treatment as effective?

As long as your child wears the aligners as directed, the answer is yes: they are just as effective as traditional braces. A small blue spot on the back of each aligner will fade after two weeks of proper wear. This enables Dr. Nathan R. Yetter to tell whether the child is wearing the aligners.

Can Invisalign aligners be removed?

The recommended amount of time to wear Invisalign aligners is at least 20 hours a day. They can be removed for up to four hours per day to eat, brush teeth, play sports, or play musical instruments. This makes brushing and flossing easier and helps maintain good oral hygiene!

How long does treatment take and what is the cost?

Each patient is different. Dr. Nathan R. Yetter can determine how many months your child may expect to wear the series of aligners after a consultation.

Typically, your teen will wear Invisalign clear aligners about as long as traditional braces The cost is also similar to that of other traditional braces; however, there is no set fee. The cost will depend on your child’s unique orthodontic needs.

Overall Success

Invisalign Teen treatment has had remarkable success, and patients love having straighter teeth without the embarrassment of metal braces. As your son or daughter becomes more confident, the patient will actually be more likely to keep up with the treatment and complete it sooner.

Do you ever find yourself gnawing at your nails? Nail-biting is a very common and difficult to break habit which usually has its beginnings in childhood. It can leave your fingers and nail beds red and swollen. But if you think that your nails are the only ones getting roughed up by nail-biting you'd be mistaken—so are your teeth!

According to a study by the Academy of General Dentistry, those who bite their nails, clench their teeth, or chew on pencils are at much higher risk to develop bruxism (unintentional grinding of the teeth). Bruxism can lead to tooth sensitivity, tooth loss, receding gums, headaches, and general facial pain.

Those are some nasty sounding side effects from chewing on your nails. Most nail-biting is a sign of stress or anxiety and its something you should deal with. So what steps can you take if you have a nail-biting habit?

There are several things you can do to ease up on nail-biting:

• Trim your nails shorter and/or get regular manicures – Trimming your nails shorter is an effective remedy. In so doing, they'll be less tempting and more difficult to bite on. If you also get regular manicures, you’ll be less likely to ruin the investment you’ve made in your hands and fingernails!
• Find a different kind of stress reduction – Try meditation, deep breathing, practicing qigong or yoga, or doing something that will keep your hands occupied like squeezing a stress ball or playing with a yo-yo.
• Wear a bitter-tasting nail polish – When your nails taste awful, you won't bite them! Clear or colored, it doesn't matter. This is also a helpful technique for helping children get over the habit.
• Figure out what triggers your nail-biting – Sometimes it's triggered by stress or anxiety and other times it can be a physical stressor, like having hang nails. Knowing what situations cause you to bite your nails will help you to avoid them and break the habit.
• Wear gloves or bandages on your fingers – If you've tried the steps above and they aren't working, this technique can prove effective since your fingernails won't be accessible to bite.

If you're still having trouble with nail-biting after trying these self-help steps, it's best to consult your doctor, dermatologist, or Dr. Nathan R. Yetter. For some, it may also be the sign of a deeper psychological or emotional problem.

Whatever the cause, nail-biting is a habit you need to break for your physical and emotional well-being. If you have any questions about the effects it can have on your oral health, please don't hesitate to ask Dr. Nathan R. Yetter during your next visit to our Mesa office.
