It's best for the orthodontist to see children by age 7 to advise if orthodontic treatment is required and the best time for that patient to be treated. The first permanent molars and incisors have usually come in by that time and crossbites, crowding and other problems can be evaluated. When treatment is begun early, the orthodontist can guide the growth of the jaw and guide incoming permanent teeth. Early treatment can also regulate the width of the upper and lower dental arches, gain space for permanent teeth, avoid the need for permanent tooth extractions, reduce likelihood of impacted permanent teeth, correct thumb-sucking, and eliminate abnormal swallowing or speech problems. In other words, early treatment can simplify later treatment.
Orthodontic treatment can be successful at any age, and adults especially appreciate the benefits of a beautiful smile. One of every five patients in orthodontic treatment is over 21. Jaw surgery is more often required for adult orthodontic patients because their jaws are not growing. Adults also may have experienced some breakdown or loss of their teeth and bone that supports the teeth and may require periodontal treatment before, during and/or after orthodontic treatment. Bone loss can also limit the amount and direction of tooth movement that is advisable.
Just as orthodontics repositions teeth, surgical orthodontics (also known as orthognathic surgery) corrects jaw irregularities to improve the patients ability to chew, speak, and breathe and for improved facial appearances. In other words, surgical orthodontics straightens your jaw. Moving the jaws also moves the teeth, so braces are always performed in conjunction with jaw correction. This helps make sure teeth are in their proper positions after surgery.
Your orthodontist will consider surgical orthodontic treatment for non-growing adult patients with improper bites and those with facial esthetic concerns. Jaw growth is usually completed by age 16 for girls and 18 for boys. All growth must be completed before jaw surgery can be performed. However the pre-surgical tooth movements can begin one to two years prior to these ages.
During your orthodontic treatment, which averages 18-24 months, you wear braces and will visit your orthodontist for scheduled adjustments to your braces. As your teeth move with the braces, you may think that your bite is getting worse rather than better. However, when your jaws are placed into proper alignment during orthognathic surgery, the teeth will then fit into their proper positions.
Surgery is performed in the hospital with an oral surgeon, and can take several hours, depending on the amount and type of surgery needed. In lower jaw surgery, the jawbone behind the teeth is separated and the tooth-bearing portion is moved forward or backward, as needed. In upper jaw surgery, the jaw can be repositioned forward or backward, or the jaw can be raised or lowered. Certain movements may require the jaws to be separated, with bone added/removed to achieve the proper alignment and stability. Other facial bones that contribute to alignment may also be repositioned or augmented.
When you have completed surgery, you should be able to return to school or work within two weeks. After the necessary healing time (about 4-8 weeks), your orthodontist "fine-tunes" your bite. In most cases, braces are removed within 6 to 12 months following surgery. After your braces are removed, you will wear a retainer to maintain your beautiful new smile.
Two-phase orthodontic treatment is a specialized process that combines tooth straightening and physical, facial changes. The purpose of two-phase treatment is to maximize the opportunity to accomplish the ideal healthy, functional, and aesthetic result that will remain stable throughout your child's life.
Putting off treatment can result in a need for more invasive treatment later in life that may not completely fix your child's smile. Early treatment is most effective for achieving lasting results.
The goal of Phase One treatment is to help the jaw develop in a way that will accommodate all of the permanent teeth and improve the way the upper and lower jaws fit together. Children often exhibit early signs of jaw problems as they grow and develop. An upper jaw that is growing too much or is too narrow can be recognized at an early age. If children over the age of six are found to have this jaw discrepancy, they are candidates for early orthodontic treatment. Also, if children around the age of eight have crowded front teeth, early treatment can prevent the need to extract permanent teeth later.
Children benefit tremendously from early-phase treatment. Receiving early treatment may prevent the removal of permanent teeth later in life, or the need for surgical procedures to realign the jaws.
Orthodontic records will be necessary to determine the type of appliances to be used, the duration of treatment time, and the frequency of visits. Records consist of models of the teeth, X-rays, and photographs. During your child's initial consultation, the doctor will take records to determine if early treatment is necessary.
In this phase, the remaining permanent teeth are left alone as they erupt. Retaining devices may not be recommended if they would interfere with eruption. It is best to allow the existing permanent teeth some freedom of movement. A successful first phase will have created room for permanent teeth to find an eruption path. Otherwise, they may become impacted or severely displaced.
At the end of the first phase of treatment, teeth are not in their final positions. This will be determined and accomplished in the second phase of treatment. Selective removal of certain primary (baby) teeth may be in the best interest of enhancing eruption during this resting phase. Therefore, periodic recall appointments for observation are necessary, usually on a six-month basis.
The goal of the second phase is to make sure each tooth has an exact location in the mouth where it is in harmony with the lips, cheeks, tongue, and other teeth. When this equilibrium is established, the teeth will function together properly. Phase Two usually involves full upper and lower braces.
At the beginning of the first phase, orthodontic records were made and a diagnosis and treatment plan was established. Certain types of appliances were used in the first phase to correct and realign the teeth and jaw. The second phase begins when all permanent teeth have erupted, and usually requires braces on all the teeth for an average of 24 months. Retainers are worn after this phase to ensure your child retains his or her beautiful smile.
