What Is A Membrane For Implant
A membrane is simply a barrier that acts mechanically and biologically against cell invasion that is not included in the formation of bones.
The essential function of a membrane barrier is that it allows selective cell repopulation and also helps in guiding the rapid increase of various tissues during the healing process.
If a barrier membrane is not utilized, it will result in soft tissue integration and exposed bone growth.
The membranes used in GBR techniques are divided into two categories;
• Non resorbable membranes are membranes that do not react, thus requiring a second surgical procedure to remove after completion of bone regeneration.
• Resorbable dental membrane are membranes that can decompose quickly and that restoration rates varies of a membrane material An ideal membrane should have the following characteristics;
It should have the ability to maintain space to allow the process of bone regeneration.
Compatibility of the tissue – it should be able to elicit the least amount of inflammation of the membrane and the host tissue interaction to avoid infection. It should be able to provide blood clot stabilization that allows the regeneration process to progress.
The membrane’s surface should be able to prevent the fibrous tissue from attacking the graft site because that would lead to membrane porosity.
Larger pore size may inhibit bone formation by allowing overpopulation of fast-growing. The membrane should be highly durable and should have an excellent mechanical strength to protect the blood clot and to prevent the passage of unwanted cells and bacteria.
It should have a predictable rate of resorption; this means that the resorption membrane time should coincide with the regeneration rate of born tissue.
It should always be easy to modify and manipulate that is it should be able to maintain adequate stiffness to prevent the graft site from collapsing.
