What is Orthodontics?

Orthodontics is the branch of dentistry that specializes in the diagnosis, prevention, and treatment of dental and facial irregularities. The technical term for these problems is "malocclusion," which means "bad bite."

Dr. Kneib applies either fixed or removable corrective appliances to bring teeth, lips, and jaws into proper alignment and to achieve facial balance. Fixed orthodontics are brackets or appliances cemented or bonded to the teeth. Removable orthodontics are any appliances that can be removed by the patients during treatment. Any orthodontic care may need multiple phases of care. All orthodontic care needs an initial workup before treatment is rendered and diagnosed.

Fixed Orthodontics

Fixed Orthodontic technology is a specialty of dental technology that is concerned with the design and fabrication of dental appliances for the treatment of malocclusions, which may be a result of tooth irregularity, disproportionate jaw relationships, or both.

There are three main types of orthodontic appliances: active, passive and functional. All these types can be fixed or removable. We provide orthodontics for both children and adults!

​Removable Orthodontics


If you’ve always wanted straight teeth, but never liked the idea of having braces, Invisalign® may be the perfect treatment for you. Invisalign® is a clinically proven method to straighten teeth that uses a series of clear removable aligners instead of metal wires or brackets.

Determining if Invisalign® is right for you

Our office will give you an initial examination to determine if the Invisalign® treatment is right for you. If it appears that it is an option, we will take photographs, X-rays, and an impression of your teeth.

Dr. Kneib, a certified Invisalign® dentist, will then complete further diagnostic analysis to verify that Invisalign® will work for you and create a treatment plan that will determine exactly how the teeth will be straightened. At that time, we will also be able to let you know the estimated cost and length of the Invisalign® treatment and determine if you qualify for orthodontic insurance benefits.

When the treatment plan is finalized, your records will be sent to Invisalign® along with instructions from Dr. Kneib. Using the latest advances in 3-D computer technology, Invisalign® then translates those instructions into a series of aligners, customized specifically for you.

The Invisalign® Process

The total treatment time for most Invisalign® patients averages between 9 and 15 months. During that time, most patients will wear between 18 and 30 different aligners. As you replace each aligner with the next one in the series, your teeth will move—little by little, week by week—until they have straightened into the final position your dentist has prescribed. Typically, each set of aligners is worn for about two weeks. You should wear the aligners at all times to achieve the best results, only removing them to eat, drink, brush, and floss. You will also visit our office once every six weeks to ensure that your Invisalign® treatment is progressing as planned.

MTM Clear Aligners: An alternative for minimal treatment

Other than the more commonly known clear aligner, Invisalign®, Kneib Dentistry offers an alternative, called “MTM Clear Aligner”. MTM treatment is typically for the less severe orthodontic cases that present minimal crowding of teeth. The main focus of this treatment is to address anterior teeth (front six teeth). MTM literally stands for “Minor Tooth Movement”, which means that this treatment is usually quicker and requires less visits to the dentist. Due to the minimal amount of treatment, it typically translates to a less costly form of orthodontic care.


Retainers are the appliances that keep your teeth straight at the end of treatment. This is a very important phase of treatment as without them your teeth could go slightly crooked again throughout growth and even in adulthood. As a general rule, we recommend that teenagers wear their retainers at least until they finish growing and that adults wear them indefinitely.

They come in two general forms. Removable retainers look like a much thinner version of a rugby player’s mouth guard; in fact, they are almost identical to an Invisalign® aligner (see above). This type is usually worn just in bed at night. Fixed Retainers consist of a fine wire glued to the tongue side of the teeth; these are generally left in place for an extended period of time.

Retainers are the last vital element of Orthodontic treatment.
