Reverse pull headgear, also known as a face mask, is a type of fixed orthodontic appliance that is used to correct underbites by pulling the upper jaw forward. It is a crucial component of orthodontic treatment for Class III malocclusions, underbites, and crossbites.
What is Underbite?
Underbite is a condition where the lower front teeth and jaw protrude in front of the upper front teeth. This can cause problems with biting, speaking, and smiling.
Why Use Reverse Pull Headgear?
Reverse pull headgear is used to correct underbite by applying gentle pressure to the upper jaw, pushing it forward and backward. This allows the lower jaw to meet the upper jaw in proper alignment, improving overall chewing function and aesthetics.
How Does Reverse Pull Headgear Work?
Reverse pull headgear consists of a metal frame that is fastened to the front of the face, usually at the chin and forehead, and elastic bands that connect to brackets on the upper teeth. The elastic bands exert tension on the brackets, moving the upper jaw forward and downward.
What Are the Different Types of Reverse Pull Headgear?
There are several types of reverse pull headgear, including:
-
Cervical headgear: This type is worn behind the neck and is used to correct an overbite.
-
Reverse-pull headgear: This type is worn on the face and consists of two padsconnected by a vertical frame that pulls the upper jaw forward.
-
High-pull headgear: Similar to cervical headgear, but the strap wraps around the back of the head.
What Are the Benefits of Using Reverse Pull Headgear?
There are several benefits to using reverse pull headgear, including:
-
It provides additional force to speed up orthodontic treatment in cases that require it.
-
It can correct severe underbites and crossbites that are difficult to treat with traditional braces alone.
-
It can help prevent the need for jaw surgery in the future by correcting jaw alignment early on.
What Are the Potential Side Effects of Using Reverse Pull Headgear?
While reverse pull headgear is generally effective, it may cause some side effects, including:
-
discomfort and soreness during the first few weeks of wear
-
rubbing on the skin, causing irritation
-
difficulty eating certain foods, such as caramels or hard candies
-
potential increased risk of tooth decay due to changes in口腔卫生 habits caused by the headgear

-
Clean the headset regularly according to the manufacturer's instructions.
