The use of autogenous tooth-bone graft materials (ATBG) in implant dentistry is growing in Korea. However, a KAID-level evaluation of the materials and procedures is required. Prior to the ATBG assessment, "excellent bone graft materials" had the following qualities:

1. Revascularization capacity;
2. Angiogenesis, osteoconduction, and osteoinduction ability;
3. Grafted bone matrix density and remodeling;
4. Resistance to infection
5. economical
6. simple to handle.

Angiogenesis and osteogenesis are the two most crucial graft material properties, and the reproducibility of these characteristics may be a determining factor in "excellent graft materials."

Therefore, if the graft develops into healthy tissue that withstands infection and wound dehiscence with early stabilization and epithelization, the long-term result may also be favorable. It is crucial to use any material as a bone graft for dental implants because the histology of every instance could not be clinically verified.

Because of its superior osteogenesis and resistance to infection, autogenous bone has long been considered the gold standard. However, autogenous bone is not always easy to extract, and volume loss is unavoidable during long-term follow-up. In general, adequate bone formation can take place in the case of xenogenic bone graft material, which is frequently employed in clinical practice, under favorable regeneration settings, such as sinus lift or socket preservation. Although adequate volume was maintained, it was uncertain whether bone development had truly advanced to the end despite extensive vertical and/or horizontal augmentation. Furthermore, infections in sinus graft cases could not be addressed until the xenograft was removed completely. A patient who has had implants may also have this susceptible feature of infection. The application of ATBG, which has been enhanced for the flaws, is covered in this section.
