The words “overbite” and “overjet” certainly sound similar. Both conditions concern your front teeth. Both conditions fall under the same category of bite problems—Class II malocclusions, if you want to be technical. So it’s not surprising that they’re often used interchangeably. But while there are similarities, overbite and overjet are also distinctly different.

• Overbite/Overjet Geometry

In a healthy bite, the front top teeth project slightly beyond, and slightly overlap, the bottom teeth. The key word here is “slightly.” With a Class II malocclusion, the upper front teeth project further beyond the lower teeth than they should.

Of course, teeth and bites are as individual as we are, so there are variations in just how and just how much the overlap occurs. In diagnosing an overbite vs. an overjet, the difference comes down to a matter of vertical vs. horizontal.

An overbite, or deep bite, occurs when the top teeth vertically overlap the bottom teeth more than they should for a healthy bite. Generally, when a person’s top teeth cover more than a quarter of the bottom teeth when biting down, or more than two to three millimeters, that person is said to have an overbite.

An overjet, commonly known as protruding or buck teeth, is the result of a horizontal overlap that is broader than normal. This causes the top teeth to project outward toward the lips more than they do in a typical bite. An overjet is usually diagnosed when the horizontal distance between the top and bottom teeth exceeds two to three millimeters.

• Overbite/Overjet Causes

The causes for both an overbite and an overjet might be dental (caused by tooth alignment), or skeletal (caused by bone development), or a combination of both. These bite problems can run in families. They are also affected by the size and position of the jaws and the shape and position of the teeth.

Early oral habits, such as prolonged and vigorous thumb-sucking or pacifier use, can also contribute to the development of a Class II malocclusion, particularly an overjet. Consistent pressure from thump or pacifier pushes the teeth outward as they erupt, which encourages them to protrude. These oral habits can affect the shape of the palate and jaw, too.

• Overbite/Overjet Treatments

There are many types of treatment available to correct teeth and bite misalignments. Dr. Nicola Crichigno will tailor your treatment to your specific malocclusion for the best orthodontic outcome.

If you have a mild malocclusion, and minor dental issues are the main cause of that malocclusion, either braces or clear aligners can be effective for an overjet or an overbite. Elastics (rubber bands) are often used as part of this treatment.

If the malocclusion is due to bite problems caused by uneven upper and lower jaw development, devices called functional appliances can be used with braces to help guide the growth of the jawbones while young patients’ bones are still forming. These include appliances that work inside the mouth to help the upper and lower jaws grow proportionally, and external appliances such as headgear.

In some cases, where the malocclusion is skeletal in nature as well as dental, surgical treatment might be necessary to reshape the jawbone itself. Orthodontic treatment is usually needed as well both before and after surgery.

• Overbite/Overjet Consequences

Over time, a deep overbite can cause damaged gum tissue, worn enamel, and fractured teeth. When teeth protrude because of an overjet, they can lead to self-consciousness and are more at risk for injury. Both malocclusions share dental and medical consequences, including concerns about facial and jaw appearance, problems speaking or chewing, headaches, and face and jaw pain.

Class II malocclusions aren’t all the same, and orthodontic patients aren’t all the same either. You may have a minor malocclusion or a significant one. You may have an overbite, or an overjet, or a combination of different bite and alignment concerns. Your malocclusion may not bother you at all, or it may cause pain, discomfort, or self-consciousness.

That’s why every overbite or overjet should be evaluated by an orthodontist. When you visit our Stoney Creek orthodontic office, Dr. Nicola Crichigno will be able to diagnose the exact nature of your malocclusion, the reason for it, and your best individualized treatment plan. An overbite and an overjet are different malocclusions, but you and your orthodontist want the same outcome for each: a healthy, attractive, and confident smile!

You can learn just about anything on the Internet these days. You can also order just about anything on the Internet these days.

But would you order your braces on the Internet? There’s a new trend involving websites that claim to offer a solution for straightening teeth, without your ever seeing a dentist or orthodontist in person.

These companies usually have patients take an impression of their teeth using putty and a tray. Then you mail the impressions back to the company where a dentist reportedly examines them and suggests a course of treatment using 3D modeling software.

A series of clear aligners are made, to be worn by the patient in order to attain the desired result. Although this form of orthodontic treatment may cost less than seeing an orthodontist in person, there are several reasons why you should avoid it:

• Potential health hazards are missed: If your oral health is not up to par (e.g., you have cavities, gingivitis, chipped teeth, etc.), an orthodontist would not suggest orthodontic treatment. Only after these issues are addressed would treatment be considered as an option. Whether this is the case with a person can’t be known when all the doctor sees is a set of impressions.
• Lack of information about the patient: Before you receive any orthodontic treatment, an orthodontist will have X-rays taken to make sure you are a good candidate. If the bones or teeth do not look like they would align properly with treatment, another course of care may be suggested, even necessary. None of this background is available to over-the-net orthodontic providers.
• No regular checkups: The purpose of regular checkups with Dr. Nicola Crichigno is to ensure that everything is moving properly, on schedule, and most important, safely. This lack of hands-on care with Internet orthodontics could be a hazard for you as a patient and has the potential to do more harm than good.

It’s not worth the risk of getting orthodontic treatment over the net just to save some money. Our Stoney Creek office is committed to working with you, whatever your financial situation may be.

Let’s work together to give you the smile you deserve!

By now, you’re very familiar with the basic building blocks of your braces. Brackets, wires, and ligatures are no mystery to you. But suddenly, you’re hearing a brand new term—“power chains.” What exactly are these power chains, and why does your orthodontist think you need them? Let’s see how power chains are *linked* to your orthodontic treatment.

• First, why power chains?

They’re not really chains in the necklace or bike chain sense—in fact, they’re only very rarely made with metal. These chains are most often a string of O ring loops just like your elastic ligatures, attached in a row to resemble a chain.

Chain lengths are tailored to your specific needs. Dr. Nicola Crichigno will attach each individual loop in the chain around a single bracket, linking selected teeth together. Chains might stretch across a few teeth, several teeth, or your entire upper or lower arch.

• Second, why power chains?

Because these chains are usually made of the same elastics that your ligatures, or bands, are made from, they want to hold their original shape. They will try to return to that original shape even as they are stretched between your brackets. As they contract, they help move your teeth together. 

Over time, just like an over-stretched rubber band, they lose their elasticity, and won’t work as effectively. That’s why you’ll probably get a new power chain whenever you come in to our Stoney Creek office for an adjustment.

• Third, why power chains?

This is the most important question. How can a power chain improve your smile?

Usually, power chains become part of your treatment after the first phase of alignment. They can be used to help align your teeth or correct your bite, but are most often used to close gaps between the teeth.

You might have a gap after a tooth has been extracted. Or, as your teeth move into their new positions, you might suddenly see noticeable spaces between them. Power chains move the teeth closer together to eliminate these gaps, and do it more quickly than brackets and wires alone can do.

• How long will you need them?

This is something Dr. Nicola Crichigno will discuss with you. Whether it’s a matter of weeks or months, your treatment plan is designed to move your teeth into their best positions, and to do it carefully for a lasting, healthy alignment.

• Power chain options

Depending on the size and spacing of your teeth and your treatment plan, these chains usually take one of three forms: closed/continuous, short, and long. The only difference is the distance between the rings.

We will choose the type of chain that’s best for your treatment. Your contribution is to personalize your power chain. Power chains come in a rainbow of colors, allowing you to mix and match. You can even coordinate with your ligatures if you have ties as well as chains. If your goal is to have your braces blend in, various shades of white, silver, or clear colors are available. Want to mix things up? Choose a different color with every adjustment.

• Anything else?

You might experience some discomfort for the first few days with a new power chain, just as you might with any adjustment. Dr. Nicola Crichigno will have suggestions for making those first days as comfortable as possible.

Also, like brackets and ligatures, power chains can trap food particles, so be sure to follow our instructions for keeping your teeth and your braces their cleanest.

Now that you’re all caught up on what power chains are and what they can do for you, let’s mention one more benefit. This is a process where you can actually see the gaps between your teeth closing over the weeks you wear your power chains. Keep a selfie record of your progress as you create your beautiful, healthy smile. That’s an em*power*ing experience!

The purpose of braces and other forms of orthodontic treatment at Crichigno Orthodontics is to correct malocclusion, also known as crooked or crowded teeth, or “bad bites.” Past orthodontic practice dictated that wisdom teeth be removed, especially in cases of crowding.

The wisdom teeth are the last teeth to come in, and are officially known as the third molars. The teeth typically erupt, or break the surface of the skin, in young people between the ages of 13 and 20.

Sometimes, wisdom teeth are impacted. That means they cannot break through the gum tissue. This typically happens when the mouth or jaw is too small to accommodate the teeth. Impacted wisdom teeth can become infected, and some dentists and orthodontists may want to remove them as prophylaxis to prevent possible future infection.

Justification for removing wisdom teeth

Dr. Nicola Crichigno will tell you that in some cases, wisdom teeth attempt to come in the wrong way, either tilting in the jaw, or sideways. If the mouth is too small to accommodate these additional teeth, they inevitably become impacted. Swelling or infection of the gum flap above an impacted wisdom tooth may cause pain. The greatest danger is pericoronitis, a potentially dangerous infection that can occur in the gum area around an impacted wisdom tooth, or around a wisdom tooth that has erupted.

Orthodontists base their decision to remove wisdom teeth on each patient's individual circumstances. To learn more about the impact wisdom teeth have on orthodontic treatment, or to schedule a visit with Dr. Nicola Crichigno, please give us a call at our convenient Stoney Creek office!
