Posts for tag: clear orthodontic aligners
If you are dissatisfied with the way your smile looks, and your dentist is unhappy with the way your teeth fit together — but you don't like the idea of wearing braces — clear aligners may be your best solution. How much do you know about this teeth-straightening alternative? Below are some FAQs on the subject.
What do we mean by clear aligners? Clear aligners are a system for straightening teeth that uses clear plastic removable “trays” that fit over your teeth. As the teeth move to fit the trays, new trays are substituted that are designed to continue to move your teeth into the desired position. This system is an alternative to the traditional system of brackets and wires known as braces.
How can teeth be moved to new positions? The connection that holds a tooth in place in your jaws — the periodontal ligament — is not immobile. It constantly changes its position based on the normal forces of your bite. As the ligament is pushed on one side and pulled on the other, the living cells of your mouth respond by depositing bone and cementum (the protective covering of the tooth's root) on one side and dissolving it on the other. Normally this happens in a balance, maintaining your teeth in their position. We can manage these slight changes by applying constant light forces to move teeth in a predictable way.
How long does it take to move teeth to their optimum position using clear aligners? As with braces, the process is gradual. Total treatment time can range from six months to two years.
Do the trays have to be worn all the time? As you move through the sequence of trays, each is worn for 20 hours per day for two weeks. They may occasionally be removed for important social occasions.
How does an orthodontist design the sequential trays that are used? The trays are designed using a computer, based on an assessment and images of your mouth, teeth and jaws.
What kinds of problems can clear aligners correct? This method works well to correct mild to moderate crowding or spacing. If your back teeth already fit together as they should, the system may be ideal. If you have an extreme overbite or underbite, braces might work better.
Are clear aligners an alternative for everyone? Clear aligners are recommended for adults and recently, teenagers. They are not usually recommended for young children.
Why is it important to have your teeth straightened? Besides the obvious benefit of feeling better about yourself and your appearance, straight and well-aligned teeth work better. You will experience a better-functioning bite and can improve your oral health.

Compared to traditional braces, orthodontic clear aligners seem miraculous in many ways, almost too good to be true. You may be wondering if they really work. The answer is yes — but they are not for everyone.
What are orthodontic aligners and how do they work?
Clear orthodontic aligners are an alternative to traditional braces that are used to move your teeth and transform your smile without much interference to your daily life. They are removable trays made of a clear plastic material that is essentially invisible.
When using aligners, a sequence of slightly different trays is custom-made to fit over your teeth. You must wear each one 20 hours a day for two weeks before changing to the next in the series. The aligners are computer generated, designed by state-of-the-art techniques based on models and images of your own teeth. They work because slight changes in the sequential aligners gradually shift your teeth. If they are worn consistently, the process takes from six months to two or three years.
Advantages over traditional braces are:
- The aligners can be removed for eating, drinking, brushing, flossing and social occasions.
- They have no rough edges or wires, making them more comfortable.
- Changes become visible quickly as your teeth move into their new, better positions.
Clear aligners are a good solution for correcting mild to moderately crowded or incorrectly spaced teeth. They are most effective if your back teeth already fit together properly. Clear aligners are usually effective in correcting simpler or tipping movements of teeth in two dimensions. For more complex movements, traditional braces may be required. Clear aligners are usually recommended for adults whose teeth and jaws are fully developed, and not for children.
When do you need traditional fixed braces?
Traditional braces are fixed brackets attached to the teeth through which narrow, flexible wires are threaded. They may be necessary if your teeth do not meet properly, creating too much overbite or underbite. Closing spaces where teeth are missing, rotating teeth, or other complicated situations probably make you a better candidate for traditional braces.
Each particular situation is unique. To find out if clear aligners are right for you, make an appointment with us for an assessment and diagnosis of your own situation. For more information see the Dear Doctor magazine article “Clear Orthodontic Aligners.”
Metal braces for correcting teeth alignment have long been a fixture of adolescence. But although they're effective, they tend to put a crimp on a teenager's life with changes in diet and irritation and discomfort from the devices and regular adjustments. For many teens, though, these are minor compared to the change in their appearance that comes with traditional braces, and the embarrassment they may feel.
In recent years, there's been a growing use of another orthodontic device that reduces many of these inconveniences, especially regarding appearance. Known as the clear aligner, this transparent, “almost invisible” device can be taken out for eating, cleaning or important social events.
Clear aligners are a sequential set of clear trays made of polyurethane plastic that are generated for an individual patient using information derived from x-rays, photographs or models. Each tray in the sequence is slightly different from the previous one to account for the tooth movement achieved wearing the previous tray. The patient will wear a tray for about two weeks and then, if all looks well, move to the next tray. This process continues until the teeth arrive at the proper alignment, a period of about six to twenty-four months depending on the patient's initial condition and their progress.
Up until recently, aligners were a viable option for a limited category of patients, mainly adults. Recent advances have changed that. Aligners now include tiny “power ridges” that enable them to move teeth in more than one plane, something previous versions were unable to do. “Eruption tabs” can also be incorporated into aligner sets to hold the space for permanent teeth that haven't erupted yet — a must for many younger patients. We can also temporarily bond attachments to the teeth known as buttons (made with a composite that blends in with the natural tooth color) that give more leverage and stability to the aligner.
With these changes, clear aligners are now an effective choice for a wider group of patients, including many teens. Aligners are comfortable to wear, easy to care for, and for teens acutely conscious of their appearance, less obtrusive than traditional metal braces.
