Dental caries and periodontal disease are public heath problems. 100% of people from low-medium and low socio economic levéis have caries. 92.19% of people between 35 and 74 years of age have periodontal disease. Both pathologies may cause teeth fall down. Titanium implants could improve prognosis of prosthetics treatments, but frequently requires increase bone volume, to restore shape and function. The research wants to know state of art in use of biomaterials in bone regeneration. Best biomaterial properties were shown by autologous bone (AB), however, do exist alternatives such as allograft (AL) and bone matrix (BM). AB has shown best prognosis, from endochondral (EC) and intramembranous (IM), with 357% and 642% most bone formation compared to AL IM. AB IM type is successfully compared to EC (IM shown 166% more bone formation). AB access is limited, this fact have made necessary use other biomaterials. AL combined with BM produce 224% more bone compared to AL. Membrane use improves long term stability of IM and EC bone. AB EC type is the most successful biomaterial. Considering limited access to this bone, it could be used combined with bone matrix. Membranes have shown increase long term stability of biomaterials.
