For people with alveolar bone resorption and atrophy, if they want to make a healthy implant, they may first need to increase the bone mass, that is, artificial bone powder and periosteum are implanted into the missing parts of bone to increase the height and depth of alveolar bone. So, what materials are these bone powder and periosteum made of?

In fact, there are four commonly used bone meal materials

1. Allogeneic bone - bone powder made from donated bone is highly osteogenic, but relatively expensive.

Heterogeneous bone - mainly made of animal bone, mostly cattle bone and pig bone, with moderate price.

3. Synthetic bone - it is a chemical compound with low price and high utilization rate, but the osteogenesis is ordinary, but it also depends on individual constitution.

4. Autogenous bone - bone powder made from one's own teeth, or a small part of the mandible.

Note: Commonly used xenogeneic bone brands include domestic Zhongjin calf bone (BRM), Ruibang bone powder, Yirui, Haiao bone powder, and Swiss biooss bone powder.

The material of periosteum is mostly type I collagen

The periosteum is mainly made of bovine pericardium tissue, mainly composed of type I collagen, which retains the natural collagen fiber structure of the pericardium, has good elasticity, and can also provide long-term barrier effect.

The role of periosteum mainly depends on the bright spots. One is to isolate the wound from oral contact; The second is to prevent the implanted bone powder from being rapidly absorbed.

reminder:

Tip ①, there is also a titanium mesh, which can also be used to wrap bone powder.

It is suggested that ② bone graft powder has a certain absorption rate. The absorption rate of the selected bone powder material should be coordinated with the osteogenic rate of the new bone, otherwise the bone powder material is easy to be absorbed too quickly and the osteogenic effect is not very good.

Therefore, high-quality bone powder materials such as autologous bone and calf bone should be selected as far as possible.
