INTRODUCTION Dental appliances are common parts of dentistry and orthodontics. A dental appliance refers to any device that helps with your treatment plan for you. These appliances can be permanent or removable. They help to repair damaged teeth, straighten crooked teeth, and replace missing teeth. Dental appliances are fitted to your mouth specifically to give you the best outcome from your orthodontic care.

THERE ARE TWO TYPES OF DENTAL APPLIANCES * Permanent Dental Appliances *Removable Dental Appliances

PERMANENT DENTAL APPLIANCES RAMY BAHAA

1. CROWNS AND FILLINGS Though you may not think of crowns and fillings as “appliances,” they’re dental devices that replace missing tooth parts once you’ve had a cavity repaired.

2. BRIDGES A bridge is fixed between your existing teeth when you’ve had to have a complete tooth extraction or are missing one or more teeth in a row. Unlike partial dentures, you do not remove your bridge. It remains a permanent part of your teeth, both to maintain your bite’s existing structure and to keep daily tasks like eating easy and normal for you.

3. BRACES While not permanent for your entire life, braces are permanent in the sense that they remain on until your teeth have been moved into alignment.

REMOVABLE DENTAL APPLIANCES RAMY BAHAA

1. PROSTHETIC The most common type of prosthetic dental appliance is dentures. Dentures exist in several forms: partial and full. Partial dentures fit in part of your mouth where there are missing teeth. The new style of partial dentures are constructed of a flexible material that moves more naturally and easily with your mouth. Full dentures replace complete tooth loss on the upper jaw, lower jaw, or both jaws.

2. MOUTH GUARDS Mouth guard typically means the type of guard you wear during sports events, but there are also night guards that protect against tooth grinding that happens during sleep. Whether you wear a mouth guard for sport or to keep you from grinding your teeth at night, that guard counts as a dental appliance. Another type of guard, called the tongue thrust guard, prevents you from pushing your tongue against your front teeth while your mouth is closed. This kind of behavior can result in crooked teeth and bite problems.

3. AIRWAY AND SNORING Nighttime teeth grinding is just one oral problem people face while sleeping. Snoring can signify you’re not breathing as well as you should while you sleep, and it can disrupt your partner, too. Snoring dental appliances will change the position of your jaws or tongue while you sleep, opening up your airways and cutting back on the soft tissue that vibrates and causes snoring. As a bonus, you can’t grind your teeth while you’re wearing one of these devices, either. Snoring is a sign of sleep apnea, too. If you have sleep apnea, your doctor and dentist might work to come up with a dental appliance solution to this issue. Sleep apnea can be a dangerous condition which leads to heart problems and in extreme cases, death. Dental appliances are only one treatment option for sleep apnea, and may be used in conjunction with other treatments.

4. ORTHODONTIC RETAINERS The completion of treatment with brackets and arch wires or Invisalign marks the beginning of the retention phase. This final treatment phase lasts for at least two years. Your final orthodontic result depends on your retainers, so don’t short-change this investment in your smile. Retainers must be removed before brushing, and they should be brushed before placing them back in your mouth. Retainers keep your teeth in place after having orthodontic work done. When you have your braces removed, your orthodontist will fit you with a retainer. Typically you wear the retainer at night to keep your teeth in place, though some patients have to wear it day and night for a while after having braces removed.

5.PALATAL EXPANDER Bonded to the upper molars, the Rapid Palatal Expander is an orthodontic appliance that creates more space in the upper jaw. It often is used to provide a better relationship between the upper and lower jaw, or when the upper teeth are crowded or blocked out of the dental arch. This appliance is used in children who are still growing. A child’s connective tissue between the left and right halves of the upper jaw is responsive to expansion. The expander widens the palate bit by bit each time the patient turns a screw in the center, using a special key we provide. The pressure created during this phase encourages bone growth between the right and left sides of the jaw, and ultimately results in increased width.

6. SEPARATORS Separators/spacers are little elastics that fit tightly between teeth to create more room for bands to be placed around them later. Spacers can fall out once the space is created. You can tell whether they must be replaced by slipping some dental floss between the teeth. If the floss gets stuck, the spacer hasn’t made enough room and must be replaced prior to your banding appointment.

7.HUMPHREY’S APPLIANCE Occasionally, as a 6-year molar erupts, it can get caught under the curve of the baby tooth in front of it. One way to correct this is by extracting the baby tooth it is caught under (and is causing damage to), then moving the 6-year molar back to its proper spot using an orthodontic appliance. Then, a holding appliance would be placed until the permanent premolar is ready to replace the baby tooth that was lost. In some cases, we are able to use a Humphrey’s Appliance to both save the baby tooth, AND move the 6-year molar backward. Once the permanent tooth has been moved into its proper position using the Humphrey ‘s Appliance, the appliance can be removed. This eliminates the need for a holding appliance, because we did not have to extract the baby tooth.

CARING FOR DENTAL APPLIANCES :- YOU NEED TO CAREFULLY BRUSH YOUR PERMANENT DENTAL APPLIANCES, THE SAME WAY YOU BRUSH YOUR NATURAL TEETH. YOUR DENTIST WILL RECOMMEND SPECIFIC BRUSHING TECHNIQUES, BUT GETTING ALL SURFACES OF THE TOOTH AND BRUSHING FOR AT LEAST TWO MINUTES IS RECOMMENDED. Cleaning removable appliances is a bit different. For some, you can brush them with toothpaste and rinse them before putting them back in. Others you can clean in denture cleaning solution and store in a safe case when you’re not using them. Your dentist or orthodontist will go over the cleaning specifics. Always make sure you clean your appliances well, because bacteria can grow on them, putting your oral health at risk. Dental appliances help to fix oral problems that many people face. If you’re wondering about getting a dental appliance to straighten your teeth or help with sleep, talk to your dentist today. The right treatment plan and appliance could significantly improve your quality of life.
