Orthodontics is a specialized field of dentistry that deals with the proper alignment of teeth and jaws. It is also known as dentofacial orthopedics. Orthodontic treatment involves the use of different types of braces and other appliances to correct bite problems such as overbite, underbite, openbite, and crossbite. These bite problems can cause various dental and oral health issues, including speech problems, tooth decay, and gum disease.

Overbite, also known as a deep bite, is a type of bite problem where the upper front teeth overlap the lower front teeth excessively. In some cases, the upper teeth may even cover the lower teeth completely. Overbite can lead to excessive wear and tear on the teeth, gum irritation, and jaw problems.

Underbite, on the other hand, is a type of bite problem where the lower teeth protrude outwards beyond the upper teeth. This can cause difficulty in biting and chewing, speech problems, and jaw pain. Underbite can also cause wear and tear on the teeth, leading to tooth decay and gum disease.

Openbite is a type of bite problem where the upper and lower teeth do not meet when the mouth is closed. This can cause speech problems, difficulty in biting and chewing, and jaw problems. Openbite can be caused by habits such as thumb-sucking or tongue-thrusting, or by jaw problems.

Crossbite is a type of bite problem where some of the upper teeth are positioned inside the lower teeth when the mouth is closed. This can cause wear and tear on the teeth, gum disease, and jaw problems. Crossbite can also lead to speech problems and difficulty in biting and chewing.

To correct these bite problems, orthodontists use different types of braces and appliances. One of the most commonly used appliances is the adjustable headgear. This appliance is used mainly to correct underbite and overbite problems. The headgear consists of a metal wire that is attached to the braces on the teeth and a strap that goes around the back of the head or neck. The adjustable headgear applies gentle pressure to the teeth and jaw, gradually moving them into the correct position.

In conclusion, orthodontics is an important branch of dentistry that focuses on correcting bite problems and improving oral and dental health. Overbite, underbite, openbite, and crossbite are common bite problems that can cause various dental issues if not corrected. The use of appliances such as the adjustable headgear can help correct these bite problems and improve overall dental and oral health.
