Biocompatible material bars adapted to prevent the interdental bone peak resorption following dental procedures and/or periodontal diseases are described. The biocompatible material bars have different shapes, are made out of biocompatible material and have different surface treatments, which avoid the interdental bone peaks resportion following dental procedures and/or periodontal diseases. The bars of biocompatible material are thin and likewise small-sized in length and width in order to fit the interdental bone size. The bars may have different shapes which make them suitable to be completely inserted into the interdental home, thus matching its shape and size without portions external to the bone. The bars may have surface treatments which favour their implantation and osseointegration.
