Orthodontic malocclusions are classified according to the position of the teeth and the relationship of the bones in the jaw.
Class I
is a normal relationship between the upper teeth, the lower teeth and the jaws or a balanced bite.Class II
is when the first lower molar is posterior (or more toward the back of the mouth) than the first upper molar. In this abnormal relationship, the upper front teeth and the mandible project farther forward than the lower teeth and the mandible.It has a convex profile with a retracted chin and lower lip. Class II problems can be caused by insufficient growth of the lower jaw, excessive growth of the upper jaw, or a combination of both. In many cases, class II problems are genetically inherited and can be aggravated by environmental factors, such as thumb sucking. Class II problems are treated by redirecting growth to harmonize upper teeth, lower teeth, and jaws.
Class III
is when the first lower molar is anterior (or more toward the front of the mouth) than the first upper molar.In this abnormal relationship, the lower teeth and jaw project farther forward than the upper teeth and jaws. It has a concave appearance in profile with a prominent chin. Class III problems are usually caused by overgrowth on the lower jaw, a weed on the upper jaw, or a combination of both. Like class II problems, they can be inherited genetically. The American Association of Orthodontists recommends that you be evaluated by an orthodontist when your child is 7 or 8 years old to detect problems that could benefit from early-stage treatment.
The skeletal or dental origin of malocclusion and, in class III skeletal malocclusions, mandibular prognatism or maxillary deficiency are important for choosing early intervention and selecting the device for treatment. While millions of children and adults each year choose to begin orthodontic treatment, there are many different types of orthodontic treatment to choose from. Your orthodontist can recommend braces for major orthodontic problems or if you want to close gaps and align your teeth quickly. Biphasic orthodontics prevents younger patients from having to receive severe orthodontic treatment later in life. Laster at Laster Orthodontics has implemented a way to make orthodontics faster and more accurate than traditional methods.
Then, Laster instructs robots to bend cables to move teeth more precisely than traditional orthodontic practices. No matter what type of orthodontic treatment you choose, it will create a beautiful smile to be proud of. Early treatment of class III malocclusions with a double reverse extension and locking face mask (PFM and RTB) could be effective because if orthodontics are implemented early while teeth and jaw bone are still developing, orthodontic treatment will be easier and less severe. The ADA and orthodontic professionals strongly advise against use of these types of treatments, which are not controlled and can cause lifelong damage to mouth. Orthodontic camouflage for class III skeletal malocclusions is a valuable service for patients and their families who cannot or do not want to consider orthognathic surgery. Camouflage treatment strategies in patients with class III malocclusions who are not developing with mild to moderate skeletal discrepancy can be achieved solely with movement of orthodontic teeth. Orthodontics is a branch of dentistry that focuses on correcting teeth and structure of patient's jaw to improve smile in general.
Crowded teeth, jaw problems, or cross bites aren't permanent condition, and orthodontic treatment can help you live life you've dreamed of.
