luunkorvausmateriaali

Luunkorvausmateriaali, often referred to as bone graft substitute or bone void filler, is a biomaterial used in orthopedic and dental surgery to fill bone defects. These defects can arise from trauma, tumor resection, or congenital conditions. The primary purpose of luunkorvausmateriaali is to provide a scaffold for new bone formation, facilitating healing and restoring the structural integrity of the bone.

There are several types of luunkorvausmateriaali. Allografts, derived from human donors, are processed and sterilized bone tissue. Autografts, taken from the patient's own body, are considered the gold standard due to their osteoconductive and osteoinductive properties. Synthetic materials, such as hydroxyapatite, tricalcium phosphate, and bioactive glasses, are also widely used. These synthetic options offer the advantage of avoiding donor site morbidity and potential disease transmission.

The selection of a specific luunkorvausmateriaali depends on factors such as the size and location of the defect, the patient's overall health, and the desired healing rate. Some materials are purely osteoconductive, providing a surface for bone cells to grow on, while others are osteoinductive, actively stimulating bone formation. In some cases, a combination of materials or the addition of growth factors may be employed to enhance the regenerative process. The use of luunkorvausmateriaali is a critical component in modern bone reconstructive surgery.
