Block bone graft in the implant therapy

Bone filler materials maybe serve serveral purposes in guided bone regeneration (GBR) procedures:

- Support the membrance to avoid membrance collaps

- Act as scaffold for bone ingrowth from the recipient site

- Stimulate bone ingrowth from the repient site

- Supply a mechanical shield against pressure from the overlying soft tissues

- Protect the augmanted volume from resorption

Moreover, the clinical indications for using bone filler materials range from grafting minor peri-implant defects to the regeneration of large continuity defects.

Bone augmentation materials include:

- Autografts (bone fillers can be derived from the person being treated)

- Allografts (from a donor and used in another individual within the same species)

- Xenografts (consist of bone mineral derived from animals or bonelike minerals derived from calcifying carals or algae)

- Alloplastic materials (synthetically derived)

Autografts are still considered the gold standard in osseous reconstructive surgery


Autograft may be havested from intraoral or extraoral donor sites such as: chin, mandibular body, iliac crest,...
