Bone Graft & Membrane

Bonegraft and membrane acts as a framework facilitating and inducing the generation of new bone. It acts as a mineral reservoir and has no antigen-antibody reaction.

It is a procedure that utilizes either a natural or synthetic substitute for replacing the resorbed or lost bone. On the basis of materials used in bone grafting, it can be classified as follows. Biocompatible and 100% safe.

 

Bone Surrounding The Extracted Socket Space

After a tooth is extracted, healing of soft tissues and bone follows. Without preservation of the extraction site, the bone surrounding the extracted socket space gradually resorbs, resulting in soft and hard tissue defects.

This reduction in quantity & quality of bone, is a source of problem for future treatment options like dental implants or prostheses, affecting their functional and esthetic outcomes.

Although the process of resorption of dental ridges after extraction is unpredictable, predominant horizontal bone loss affecting the buccal bone of the ridge is the pattern majorly observed.

To combat these hard and soft tissue defects after tooth extraction, bone grafting for site preservation is the solution. Research has shown that the sockets preserved with bone grafting on average lost 2 mm less of ridge width, 1 mm less of ridge height, and were found to have 20% more bone volume compared to sockets that were not grafted.

Indications For Bone Grafting.

Dental Implants.

  • The most common application of bone grafting for dental implants. Implants need a healthy bone in an adequate amount for reintegration. Bone grafting is the best option to restore the edentulous area where a sufficient amount of bone is absent. Sinus lift graft is the procedure involving elevation of the sinus membrane and grafting bone onto the sinus floor, for secure placement of the implants.

Ridge Augmentation.

  • Defects in the dental ridge can occur due to trauma, injury, severe periodontal disease or congenitally. The bone graft can fill the ridge and jawbone uniformity is obtained.
  • Nerve repositioning –Sometimes mandibular implants requires movement of the inferior alveolar nerve to allow for the placement of implants, a bone grafting procedure might help in this case.

Types of Bone Grafts

It is a procedure that utilizes either a natural or synthetic substitute for replacing the resorbed or lost bone. On the basis of materials used in bone grafting, it can be classified as follows.

An allograft-based bone graft involves taking tissue from one individual to another individual of the same species. Factor-based bone graft they are natural growth factors used alone or in combination with transforming growth factor-beta (TGF-beta), platelet-derived growth factor (PDGF), fibroblast growth factors (FGF), and bone morphogenic protein (BMP).

Cell-based bone grafts use cells to generate new tissue alone or can be added to a support matrix, like mesenchymal stem cells.

Ceramic-based bone graft substitutes including calcium phosphate & calcium sulfate can be used alone or in combination. Polymer-based bone grafts use degradable and non-degradable polymers alone or in combination with other materials.

There Are 2 Types Of Membranes

 

RESORBABLE MEMBRANES:

One of the materials used for resorbable membranes is Collagen. It is a heavily cross-linked protein which makes it an efficient barrier.

PRF is another leading source to create a durable resorbable membrane that tends to last 7-14 days. It utilizes platelet-rich fibrin ( Fibrin is a protein involved in blood clotting). It is made by the process of centrifugation. PRF has stretched out, slimy consistency that protects the graft.

NON-RESORBABLE MEMBRANES:

Most non-resorbable membranes are made of titanium or Dense polytetrafluoroethylene. (PTFE).To hold the membrane in place and to ensure that it keeps the bone graft covered, PTFE is often used with bone tacks.

One benefit of a non-resorbable membrane is its predictability for a successful bone generation. The downside is that it has to be removed at a second procedure. The process of bonegraft and membrane removal might differ from case to case.

It can be removed by simply plucking it out of the socket, over the graft, or it might take a long procedure involving reopening the gums, removal of bone tacks followed by membrane removal.
