A jawbone, or mandible, is the bone that forms the lower jaw. The mandible is U-shaped and articulates with the temporal bones at the temporomandibular joints (TMJ). The TMJs are the joints that allow the lower jaw to move. The two parts of the mandible are the body and the ramus. The body is the horizontal portion of the mandible.
The ramus is the vertical portion of the mandible. The two parts are connected by a hinge joint. The mandible has a number of different functions. It supports the teeth, helps to form speech sounds, and assists in chewing and swallowing. The mandible is also involved in facial expressions.
Functions of Jawbone:
The jawbone is responsible for several functions:
- Holds the teeth in place
- Acts as a attachment site for the muscles of mastication
- Supports the soft tissues of the face
- Provides a pathway for nerves and blood vessels to reach the face
- Protects the brain from injury
How to treat Jawbone loss:
If you have lost jawbone due to periodontal disease, there are a few different treatment options available.
1. Bone Grafting
This procedure involves using bone from another area of your body, or from a donor, to replace the bone that has been lost.
2. Dental Implants
Dental implants are titanium posts that are placed into the jawbone to act as a replacement for the roots of missing teeth.
3. Dentures Or Bridges
Dentures or bridges can be used to replace missing teeth.
4. Facial Reconstruction
In some cases, facial reconstruction may be necessary to restore the function and appearance of the face.
The jawbone is a critical part of the facial structure, responsible for supporting the teeth, facial muscles, and soft tissues. Jawbone loss can be a serious problem, but there are treatment options available. If you are experiencing jawbone loss, it is important to speak to your dentist or periodontist about the best option for you.
