JAWBONE

Introduction:

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.

Conclusion:

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.

 

FAQ’s:

1. Can the Jawbone grow back?

No, unfortunately once the jawbone has been lost it cannot grow back. In some cases a metal or artificial jawbone may be used to replace the missing bone.

2. What are Jawbone Dentures?

Jawbone dentures are a type of denture that is anchored into the jawbone. This provides a more secure fit than traditional dentures, which can sometimes slip or move around in the mouth. Jawbone dentures can also help to preserve the jawbone and prevent it from shrinking over time.

3. How long does it take for a Jawbone to heal?

It typically takes around 6-8 weeks for the jawbone to heal after surgery. However, it may take longer for the full healing process to be complete. Your doctor will be able to give you more specific information about your individual case.

4. Where is the Jawbone located?

The jawbone is located in the lower part of the face. It attaches to the skull at the temporal bones and articulates with the teeth. The jawbone is responsible for holding the teeth in place and helps to facilitate chewing.

5. Which part joins the tooth with the Jawbone?

The tooth is joined to the jawbone by the periodontal ligament. This ligament is a thin band of tissue that connects the tooth to the bone and helps to keep it in place. Without this ligament, the tooth would simply fall out.
