Bone regeneration and grafts

There are cases in which, for various reasons, the necessary bone is not available to be able to rehabilitate a mouth with prosthesis on implants.
In these cases it is important to carry out a study and an assessment to determine if it is possible to regenerate that lost bone, thus allowing a correct rehabilitation with dental implants.
For the placement of dental implants a minimum volume of bone is required for their anchorage, hence the importance of having a good quantity and quality of bone.
Grafts help us to recover lost tissues due to different causes, either due to dental extractions, cysts or the need to increase the amount of bone in order to carry out a satisfactory rehabilitative treatment.
There are multiple types of grafts, materials and techniques:

Types of Grafts

  • Autologous: obtained from the individual himself. Bone can be extracted from different areas of the jaw or from other parts of the body such as the hip or the fibula. The area to obtain the graft will be determined by the amount of bone required and the quality of the bone.
  • Of animal origin (xenografts): These materials come mainly of bovine or porcine origin. These materials are strictly prepared, sterilized and passed through the strictest controls in order to be used in humans. All of them are approved by the competent agencies for their use.
  • Of human origin (allografts): They are those from another genetically different individual. Like xenografts, they are strictly processed to remove any incompatible antigen present.
  • Artificial (alloplastic): These materials include Hydroxyapatite, Calcium Sulfate, ceramics, etc.

Plasma Rich In Growth Factors (PRGF)

Plasma Rich in Growth Factors (PRGF) is another factor that helps us to regenerate and prevent bone loss, for example after an extraction or after cyst removal.

Grafts

Grafts help us recover lost tissues due to different causes, either by dental extractions, cysts or need to increase the amount of bone to perform a satisfactory rehabilitation treatment.

In the case of dental implants, for its placement it is necessary to have a certain amount of bone, both in height and width and quality. The use of different types of grafts help us solve this lack of tissue.

There are different types of grafts:

Socket preservation after tooth extraction

After tooth extraction, the bone surrounding the root of the tooth begins to reshape itself and partially fill the gap left by the root.
There are techniques to promote this bone regeneration, which are performed at the time of extraction.
This technique helps prevent bone atrophy due to tooth extraction. It consists of filling the socket with a bone graft or plasma rich in growth factors and later covering it with a membrane in the necessary cases of bone grafting. The bone healing process will take several months depending on the material used and the membrane will gradually resorb. Once the bone has healed, implants can be placed.
