“…Such porosity can influence the osteoconductive characteristics of the scaffold by creating spaces for osteoblast attachment, differentiation, and growth and vascular invasion from surrounding tissues [Figure 4]. [21] Recently, Kabir et al . [22] reported that perforated root dentin matrix blocks with artificial macropores (1 mm in diameter) contributed to active bone ingrowth in critical-size bone defects of the iliac crest in adult sheep.…”

From the point of view of implant dentistry, this review discusses the development and clinical use of demineralized dentin matrix (DDM) scaffolds, produced from the patient's own extracted teeth, to repair alveolar bone defects. The structure and the organic and inorganic components of DDM are presented to emphasize the similarities with autogenous bone. Studies of DDM properties, such as osteoinductive and osteoconductive functions as well as efficacy and safety, which are mandatory for its use as a bone graft substitute, are also presented. The clinical applications of powder, block, and moldable DDM are discussed, along with future developments that can support growth factor and stem cell delivery.

“…[21] The alveolar bone volume was well maintained both vertically and horizontally, and the formed bone was not resorbed during the early stages. Histological examination showed aponeurotic fusions between the gingiva and the DDM block, osteocytic embedding, osteoclastic resorption, and vascular invasion into the DDM block.…”

“…Regarding the properties of healing, ABTB has almost same composition with autologous bone such as Type I collagen, minerals and several proteins [14,19,20]. Structurally, ABTB has 0.2-0.3 mm diamter macropores to enhance vascular invasion from the host tissues and 3-5 µm diameter micropores for exchanging proteins between host tissues and dentin matrix.…”

“…Kim et al reported that the osteoinductive and osteoconductive functions of ABTB were verified by histological examination [19,[20][21][22]. Kim et al also reported in the long term follow up study of ABTB that CBA, which were 41.78% in the mandible and 28.28% in the maxilla, appear to be closely related to decreases in BH because his phenomenon was mainly caused by a reduction in BH (17.03% in the maxilla and 40.8% in the mandible) rather than ARW (21.18% in the maxilla and 24.61% in the mandible) [23].…”

To replace the autogenous bone block graft in socket preservation technique that has disadvantages despite gold standard such as second surgery, more healing period and cost, the author introduces the surgical technique and five-year clinical outcome of using preformed autogenous tooth bone graft block (ABTB) which was fabricated from the patient's own extracted tooth, with simultaneous implant placement. Evaluations of the five-year clinical outcome were also performed with cone beam computed tomography (CBCT).ABTB is root dentin block composed of Type I collagen matrix with several osteoinductive non-collagenous proteins such as bone morphogenetic proteins (BMP) and dentin matrix proteins. Geometrically, alveolar bone morphology was maintained by ABTB as well as it has micropores (dentinal tubules) of 3-5 μm diameter and macropores of 0.2-0.3 mm diameter for enhancing osteoinductive and osteoconductive functions.Five year follow up with CBCT showed that alveolar bone volume and shape were maintained successfully which was repaired and restored by ABTB. This might become the effective technique for socket preservations given the well controlled long term follow up studies.

“…20,21 And then AutoBT materials were commercialized in 2008, many researches have been presented and positive results have been reported in clinic. [22][23][24][25][26][27][28] In a study of x-ray diffraction (XRD), the XRD pattern of the autogenous tooth bone graft material was similar to that of autogenous bone. 29 In an analysis of the inorganic component, the autogenous tooth bone graft material identified as low crystalline hydroxyapatite, which is similar to the minerals of human bone.…”
