Ridge Preservation

After tooth extraction, a gap called an alveolus is left:

The blood that fills the alveolus eventually clots and turns into bone. However, the previous bone contour is not retained. Without the tooth keeping it in place, the bone can reabsorb, causing issues. 

Since the gums are attached to the jawbone, they recede as the bone reabsorbs. In the case of a bridge restoration, this creates a gap that contributes to poor aesthetics, hindered hygiene, accumulated food particles, and possible inflammation:

In the case of implant restoration, bone reabsorption necessitates an extensive bone augmentation procedure beforehand. This can also lead to poor aesthetic results:

Solution

To retain the bone contour, a bone substitute material can be used, such as Geistlich Bio-Oss. This material protects the damaged portions of the alveolus and supports wound healing:

Geistlich Bio-Oss serves as a scaffold for new bone growth and is integrated with the natural bone formation after 4-6 months. 
Using bone preserving treatement (1) prevents the formation of a harmful gap during bridge restorations and (2) removes the need for extensive bone augmentation preceding an implant surgery.
