What’s the Function of Functional Appliances?

May 24th, 2023

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 Hanover, NH 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. Donald Neely to discover how an individualized treatment plan and a custom appliance can give your child a healthy bite and a lasting smile.

Ouch! Are You Biting Your Cheeks More Often?

May 17th, 2023

You’re biting into something delicious, and, Ouch! You bite into something you didn’t mean to—the inside of your tender cheek.

Painful moments like this happen every now and again. But if you find that more frequent cheek biting means that you’re extra-cautious when eating or speaking, if you wake up with sore cheeks in the morning, or if you catch yourself gnawing on your cheeks during the day, it’s time to see Dr. Donald Neely.

Causes of Cheek Biting

Many of us experience the occasional cheek chomp when we’re eating or talking. No fun! Besides the pain, a bite can cause broken skin, inflammation, a canker sore, or a cyst. Luckily, the discomfort from these accidental bites generally resolves after a few days.  

Sometimes, though, biting becomes a more frequent annoyance. Regular bites can be caused by several conditions. One of the most common?

  • Orthodontic Misalignment

If you notice that you seem to be biting your cheek a lot when eating or speaking, it could be an orthodontic problem. When your teeth or jaws don’t align properly, if your mouth is small in proportion to your teeth, or if your teeth have shifted over time, your cheeks can feel the consequences! Dr. Donald Neely can help you discover if a misaligned bite is the source of your biting problems.

But it’s not just orthodontic problems which can cause painful cheek bites. Other causes can include:

  • Bruxism

Bruxism is a medical term for tooth grinding. If you clench or grind your teeth as you sleep, it’s hard on your teeth and on your jaws. And for some people, that nightly gnashing causes cheek biting as well.

  • Wisdom Teeth

Most of us don’t have the room to welcome four new—and large—teeth. As the wisdom teeth come in, they can cause bites, especially if they erupt leaning outward toward your cheeks. They can also push your other teeth out of place.

Treatment Options

Why visit our Hanover, NH orthodontic office? A one-time bite can be extremely uncomfortable, and might lead to inflammation or a sore spot inside your mouth. Usually, these reactions fade in a short while.

But what about continuous biting? Regular biting injuries can lead to bigger problems. Tissue can get thicker or erode. Scar tissue can build up inside the mouth. Ulcers and other sores can become larger and more painful.

If you’ve been biting your cheeks more often, your orthodontist can diagnose the cause and offer you treatment options depending on the reason for this frequent biting:

  • Orthodontic Treatment

Orthodontic treatment can improve tooth and bite alignment—and can eliminate those painful cheek bites if misalignment is what’s causing them. Today’s orthodontics offers more options than ever before, for both adults and kids.

  • Traditional braces are more effective—and more subtle—than ever, with brackets which are smaller or come in clear and ceramic styles.
  • Clear aligners are a convenient, almost invisible way to treat misalignment with a series of trays which gradually improve alignment with each new set.
  • Lingual braces are attached to the back of the teeth, so there are no visible brackets and wires.
  • Functional appliances can improve and correct bite issues which braces or aligners alone can’t treat as effectively.

Whatever the reason for painful cheek biting, you deserve to eat and speak and enjoy your day without constant “Ouch!” moments affecting your comfort and health. If these moments are happening all too often, visit our Hanover, NH office for the answers to your biting problems.

Positioned for Success

May 10th, 2023

As you near the end of your orthodontic treatment, you’re probably already imagining the day when your brackets and wires finally come off. Or the moment you’ve finished with your last set of aligners. That day might come just a bit sooner if Dr. Donald Neely and our team recommend a positioner.

While not as well-known as other orthodontic treatments, a positioner is an appliance that can shorten your time in traditional braces and aligners by weeks or even months. Curious? Read on!

  • What Exactly Is a Positioner?

A positioner resembles a clear mouthguard. Its arched shape is designed to fit snugly over your teeth. It’s sometimes called a finishing appliance, because it’s designed to make those last small adjustments to your alignment and bite. If you’re a good candidate for a positioner, it can replace your braces or aligners for your last several weeks or months of treatment.

  • How Are Positioners Made?

This appliance is custom fabricated to fit your very specific orthodontic needs. Commonly, a mold is made of your teeth. A model of your teeth is made from this mold. Precision instruments are used to move the model teeth into your ideal alignment.

Once this model of your future finished smile is complete, it is used to create the positioner. When the thermoplastic material is molded to the model, it creates an appliance with an indentation for each individual tooth in its desired final location.

Available in a variety of materials, a positioner is most often designed as a clear single piece, covering both your upper and lower teeth. This makes sure that your teeth are not only aligned properly, but that your upper and lower teeth are working together for a healthy bite. Openings in the positioner provide airways which allow you to breathe easily.

  • How Do Positioners Work?

Because your teeth haven’t settled firmly into place yet (this will happen as you wear your retainer), they’re still able to move. That’s why your positioner is shaped to fit your teeth in their future ideal placement, not where they are at present.

Positioners require your active participation. Your teeth move to the ideal spots molded into the positioner through “exercise”—biting down on your appliance for 15-20 seconds before relaxing your bite, usually every 10-15 minutes during your daily wear. The gentle force provided by your jaw muscles helps guide your teeth into position more quickly. Dr. Donald Neely will give you instructions on just how to—and how often to—do these exercises.

  • How Long Are They Worn?

Positioners are commonly worn at least four hours a day to start with and all night long, or Dr. Donald Neely might recommend 24 hour a day wear for the first week. As you progress, you’ll wear them for shorter periods during the day, gradually tapering off until your treatment is complete.

Depending on the amount of correction that’s still needed, positioner use ranges from several weeks to several months. One thing that will ensure that your time in a positioner is as short as it can be is your willingness to follow our instructions. The speed and effectiveness of your final tooth movements is largely up to you!

  • Caring for a Positioner

Gentle treatment is best. Clean your positioner before and after wearing it using a toothbrush and mild toothpaste. Never boil it or expose it to heat. We will give you instructions for how to clean it more thoroughly, if needed.

Like retainers, clear aligners, and mouthguards, a positioner needs to be protected when it’s not in your mouth. Your positioner will come with a case, so be sure to use it!

Positioners aren’t recommended for every orthodontic patient. But if you feel this might be an option worth pursuing, talk to us when you visit our Hanover, NH office. A positioner could be an effective, time-saving step on your path to a lifetime of healthy smiles.

The Twin Block Appliance

May 3rd, 2023

Orthodontic treatment involves a lot more than just straightening your teeth. For a healthy smile, your bite must be healthy as well! This means that the upper and lower jaws need to fit together properly and comfortably.

If your bite is out of alignment because of jaw misalignment, orthodontic treatment can help correct the shape and position of your jaws with devices called functional appliances. These appliances are most often used for young patients whose bones are still growing, and are designed to treat malocclusions, or bite problems.

Common malocclusions such as overbites and overjets can occur when the upper teeth protrude further than they should, or the lower jaw is positioned too far back, or both. The Twin Block appliance can be used in such cases to help move your lower jaw and teeth into alignment with your upper jaw.

Why “Twin”? Because the Twin Block appliance is two separate pieces, each made of wire and smooth acrylic. Both pieces are crafted to fit precisely over your upper and lower arches and can be adjusted as your treatment progresses. The top plate can also be adjusted, if necessary, to widen the upper palate.

Why “Block”? Acrylic blocks cover the biting surfaces of several of your upper and lower teeth. These blocks fit together like a 3D puzzle. When you bite down, the upper blocks interlock with the lower blocks, pushing the lower blocks forward just a bit before you can bite down completely. Over time, bit by bit (and bite by bite), the Twin Block appliance advances your lower jaw and teeth to create a balanced, comfortable bite.

For the quickest and best results, you should wear your Twin Block appliance as directed. It’s made to be worn comfortably while you sleep, eat, and otherwise go about your day. (It’s a good idea to check with our Hanover, NH orthodontic team to see about removing it when you’re active, especially for swimming and contact sports.) When it’s time to brush, the Twin Block appliance is removable. This means that you can clean your teeth and your appliance easily.

And, while it’s made to work hard for you, it’s not indestructible. Don’t expose your appliance to heat or hot water, as the plastic may warp. Use the cleaning methods we recommend. Finally, when your appliance is out of your mouth, keep it in its case! You don’t want your appliance to end up carefully wrapped in a napkin in the nearby recycling bin. Or, even worse, in your dog’s mouth instead of yours.

The Twin Block appliance might fit together like a puzzle, but there’s nothing puzzling about how to achieve your best and fastest results. Your success really depends on you. Follow Dr. Donald Neely and our team’s advice, wear your appliance as directed, and you’ll be on your way to a healthy, comfortable bite and an attractive, confident smile!
