The Twin Block Appliance

July 20th, 2022

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 Hamilton, ON 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. Organ, Dr. Kirtane, and Dr. Hart 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!

My teeth don't line up any more. Why?

July 13th, 2022

If your teeth don't line up like they used to any more, you may be suffering from temporomandibular joint disorder, often called TMD. This is a term that can actually be applied to any condition that occurs because the temporomandibular joint (TMJ) is inflamed.

The temporomandibular joint is essentially the hinge that holds your lower jaw to your skull, and when it is inflamed or damaged in any way, it can be extremely painful. You have two temporomandibular joint, one on each side of your jaw, and it is typical to experience TMD in both sides at the same time.

Shifting of the Teeth

The reason that your teeth may not line up as they once did is that the ball and socket joints are often out of alignment and, as mentioned above, often very inflamed as a result. In order to correct the problem, Dr. Organ, Dr. Kirtane, and Dr. Hart may prescribe dental orthotics such as a lower jaw splint.

Sometimes, the wisdom teeth can play a role in the shifting of the teeth as well. If shifting wisdom teeth is combined with TMD, it may be necessary to have your wisdom teeth removed. Dental splints may follow if your teeth don't shift back to their proper positions on their own.

TMD is certainly a difficult thing to deal with, so if you experience your teeth shifting, scheduling an appointment at our Hamilton, ON office is the smartest course. We want to help you get your smile back, so give us a call anytime.

Proper Diet while Undergoing Orthodontics

July 6th, 2022

Many people undergo orthodontic treatment during childhood, adolescence, and even into adulthood. Wearing orthodontic appliances like braces is sure to produce a beautiful smile. Though orthodontic treatments at Hamilton Orthodontics are designed to accommodate your lifestyle, chances are you will need to make some dietary modifications to prevent damage to your braces and prolong orthodontic treatment.

The First Few Days with Braces

The first few days wearing braces may be the most restrictive. During this time, the adhesive is still curing, which means you will need to consume only soft foods. This probably will not be a problem, however, as your teeth may be tender or sensitive while adjusting to the appliances.

Orthodontic Dietary Restrictions

You can eat most foods normally the way you did without braces. However, some foods can damage orthodontic appliances or cause them to come loose. Examples of foods you will need to avoid include:

  • Chewy foods like taffy, chewing gum, beef jerky, and bagels
  • Hard foods like peanuts, ice chips, and hard candy
  • Crunchy foods like chips, apples, and carrots

How to Continue to Eat the Foods You Love Most

Keep in mind that you may still be able to enjoy some of the foods you love by making certain modifications to the way you eat them. For example, steaming or roasting carrots makes them softer and easier to consume with braces. Similarly, you can remove corn from the cob, or cut up produce like apples and pears to avoid biting into them. Other tips include grinding nuts into your yogurt or dipping hard cookies into milk to soften them. If you must eat hard candies, simply suck on them instead of biting into them.

If you have any question whether a food is safe to eat during your treatment with Hamilton Orthodontics, we encourage you to err on the side of caution. Of course, you can always contact our Hamilton, ON office with any questions you have about your diet and the foods that should be avoided during treatment. By following our dietary instructions and protecting your orthodontic appliances from damage, you will be back to chewing gum in no time.

The Herbst® Appliance

June 29th, 2022

Maybe you’ve known people with braces and aligners—maybe you’ve worn them yourself!—so if braces or aligners are in your teen’s future, you have some idea what to expect and when to expect it.

But quite often, orthodontic issues require more treatment than braces alone can provide. When misalignment affects not only the teeth but the jaw as well, treatment can be more effective when it begins earlier and makes use of a different kind of appliance—the “functional appliance.”

During the years your child’s bones are still rapidly growing and forming, around the ages of eight to 14, functional appliances can help guide tooth movement and encourage jaw growth and development. One of the most widely used of these devices is the Herbst® appliance.

What does the Herbst appliance do?

There are several types of malocclusions, or “bad bites” treated by Dr. Organ, Dr. Kirtane, and Dr. Hart. A common condition called a Class II malocclusion occurs when the upper jaw and teeth project too far forward over the lower jaw and teeth. Signs of a Class II malocclusion might include an overjet (protruding upper teeth), and/or a small or recessive lower jaw.

While correcting this malocclusion often enhances facial symmetry, which can be very important for a child’s confidence, correcting a Class II malocclusion also promotes jaw and dental health. Misaligned teeth are more difficult to clean, which can lead to decay and gum disease. Bite problems can cause persistent jaw pain and damage to the teeth. And, with an overjet, a child’s upper teeth are more at risk for injury.

The Herbst appliance was developed to treat this kind of malocclusion. It moves the lower jaw and teeth forward to create a balanced, healthy smile.

How does the Herbst appliance work?

The Herbst appliance is fixed in place with stainless steel bands or crowns that are secured to four teeth in the rear of the mouth, often the first molars on each side of the upper and lower jaws. The band or crown on each lower tooth is equipped with a small bar that extends toward the front of the mouth.

An arm on each side links the bands or crowns on the upper teeth to the front of the bar assemblies on the lower teeth. Each arm consists of a rod that fits smoothly into a tube. The telescoping action of the rod and tube allows the mouth to open and close normally. When the mouth is closed, the arms on both sides telescope shut, forming compact cylinders that hold the jaw forward.

While a child’s bones are still growing, the lower jaw’s new forward position can stimulate further bone growth and remodeling to maintain the jaw in that forward position. The Herbst appliance also has a restraining effect on the forward movement of the upper jaw. The result is a steady, noticeable improvement in the relationship between the upper teeth and jaw and the lower teeth and jaw.

Is the Herbst appliance hard to take care of?

The Herbst appliance is fairly low maintenance, but, like any orthodontic gear, it should be treated with care.

  • It’s important to watch your child’s diet, because sticky, crunchy, and chewy foods can damage the appliance. Save the caramels for a post-treatment celebration!
  • Carefully cleaning around the appliance is necessary, because a buildup of bacteria and plaque leads to consequences like bad breath, gum disease, and tooth decay. A water flosser can make reaching and cleaning tight spots easier if a brush alone isn’t effective.
  • If the Herbst appliance is damaged, some minor fixes might be doable at home with instructions from your treatment team. But if a band or crown comes loose, or if there’s a problem you’re unfamiliar with, call our Hamilton, ON office right away.
  • To help avoid the need for minor (or major) fixes, playing with the appliance with fingers or tongue, nibbling on pens and pencils, chewing on ice, or any other risky habits should be strictly off limits.

When it comes to your child’s health, you always have high expectations. Dr. Organ, Dr. Kirtane, and Dr. Hart and our team have all the answers you’ll need about what to expect from this phase of your child’s orthodontic treatment, and just why the Herbst appliance is the very best option to create a future of attractive, healthy smiles.
