It is thought that the technique used to harvest grafts affects the number‚ activity‚ and viability of transplanted bone tissue. Experiments conducted on pig mandibles compared bone milling‚ bone drilling‚ bone scraping‚ and piezo surgery techniques. The results showed that cell viability and growth factor expression of bone morphogenetic proteins and vascular endothelial growth factors were higher in the bone
