REMOVABLE ORTHODONTIC APPLIANCES
Contemporary orthodontic treatment involves the use of both fixed and removable appliances. Fixed appliances, also known as braces, forms a major part of the orthodontic treatment. Although removable appliance play only a supporting role in comprehensive treatment, they are important in the orthodontic treatment of children.
Removable appliances are appliances, which can be easily removed and reinserted into mouth. They consist of wires and screws held together by a plastic base and are used to move teeth and jaws into better relationships using gentle force.
What are the uses of these appliances?
What are the parts of a removable functional appliance?
The removable appliance consists of an active element or elements (i.e. metal wires and/or screws), which exert orthodontic forces on the teeth, and retentive elements (i.e. clasps), which help, in retaining the appliance in the mouth. A plastic plate holds these two sets of elements together. It is more commonly used in the correction of teeth in the upper jaw.
How are the appliances made?
Unlike braces the removable appliances are made in the dental lab. A plaster model is created from an impression of the patient's jaw, over which the appliance is designed and made. The finished appliance is then fitted on the patient.

FIXED ORTHODONTIC APPLIANCES
There are many types of fixed orthodontic appliances available to suit the individual requirements
The type of braces you get depends on a number of factors:
The severity of your bite or tooth crookedness problems
Ceramic brackets are made of composite materials. They are very strong and generally do not stain. Adults like to choose ceramic because they "blend in" with the teeth and are less noticeable than metal. These are the type of braces actor Tom Cruise had.
The ligatures (tiny rubber bands) that hold the arch wire on to the ceramic brackets are often white or clear. This looks great at first, but the ligatures can stain). Unless you eat a lot of curry, smoke, or drink a lot of black coffee, this generally isn't a problem. Note that the ligatures are changed each time you get an adjustment -- usually, monthly. It's only the ligatures that stain, not the brackets themselves!
Inspire brand brackets, , are made of pure monocrystalline sapphire and are very translucent. They are very strong and do not stain. If your teeth are already very white, then Inspire braces will look best on you and seem to "disappear" on your teeth. If your teeth are less than white, they may tend to stand out (in this case, the Ceramic brackets would be a better choice).
Invisalign braces are great for people who do not have severe problems. The "braces" consist of strong plastic trays that are fabricated especially for you. They are indeed invisible. If your bite is not severely off and your teeth are not severely crooked, then Invisalign would be a good choice. You would be able to get your teeth straightened without anyone seeing that you are wearing "braces"! This appeals to many adults, especially people who wore traditional braces as children and then need more treatment later in life. However, if your bite is very bad, if you need extractions or require headgear or other appliances, then Invisalign will not work for you; you will need to wear traditional braces.
Your orthodontist only has some control over your Invisalign treatment. The treatment trays are computer-fabricated by Align Technologies, the company that makes Invisalign. Orthodontists and dentists that offer Invisalign receive special training from Align Technologies.
Personally, I have heard that the success rate for Invisalign is only 50%. No doubt, that "failed" 50% had problems beyond Invisalign's capabilities or were treated with Invisalign inappropriately. So, if your orthodontist says that you are not a candidate for Invisalign, you should probably believe it! If he or she says that Invisalign will work for you, then great; go for it! I have known people who have had very successful Invisalign treatment and who have been very happy with the results. Many readers of this website are Invisalign wearers.
There are a couple of other companies that do systems similar to Invisalign: OrthoClearand the Red, White, and Blue System also use clear plastic aligner devices.
What is Orthognathic Surgery?
Orthognathic surgeries are cosmetic surgical procedures performed on the face to improve the esthetics and appearance. People are becoming more conscious about their looks and are more open to procedures, which helps in improving their appearance. More and more people visit an Orthodontist to improve the alignment of their teeth and there appearance. But there are limitations to what an orthodontist can do, and that is when the role of an Oral and Maxillofacial surgeon comes into play in the form of Orthognathic surgeries.
How is the procedure carried out?
Orthognathic surgeries are basically surgeries of the jaws. These surgical procedures alter the architecture of the facial body skeleton and align then in suitable positions so as to attain a final facial profile that is pleasing or infact even more beautiful to look at. Some of these procedures are very simple where as there are others that are more time consuming, complicated and expensive. The duration of surgical procedures varies from one hour to five hours under normal circumstances. Commonly treated deformities of face include severely protruding or stunted upper or lower jaw, correction of deformity of nose etc.
What are the complications and problems associated with Orthognathic surgery?
Orthognathic surgeries like any other surgical procedures have its own complications, although these complications are not as alarming. Fatal complications as a result of Orthognathic surgery is very rare, how ever the regular risk of undergoing any surgical procedure under general anesthesia cannot be ruled out.
The first and the fore most problems that an oral and maxillofacial surgeon often comes across is the acceptance by the patient. Sometimes patients find it difficult to get accustomed to his or her new face. Another common problem faced is refusal of the patient to undergo subsequent surgery done improve the appearance of his nose which may hamper the overall result.
How is Orthognathic surgery better than braces?
As mentioned earlier, if the problems are purely dental, an orthodontist might be able to rectify the problem. But skeletal problems needed to be addressed by Orthognathic surgeries.
The advantage of 0rthognathic surgery over braces is the speed at which the results are achieved. Immediate results is the greatest advantage of this surgical procedure where as braces need to be worn for at least a period of 1 year before noticeable results are seen.
How are the results of this surgery?
The results achieved after an Orthognathic surgical procedure is immediate and is usually well appreciated by the patient. Facial disproportion like protruding retruding jaws can be corrected with good functional results. Few cases show recurrences or relapse after a few years, but to a milder degree when compared to the original deformity.
