The use of autogenous tooth bone graft material has been commercialized since 2008. Autogenous tooth bone grafts always require that the tooth of the patient be extracted, and thus, the use of graft material are limited in many cases. For solution of limitation in quantity and concurrent use of autogenous tooth bone graft material, the grafting of familial teeth has been suggested. It has the following advantages: the teeth of family members are used as bone graft materials, the genetic composition is identical, and potential genetic and infectious risks can be minimized. Because the teeth of family members are used, a good tissue affinity is obtained, and thus, superior bone generation rates compared to those observed for allogenic or xenogenic bones can be anticipated. We used familial tooth bone-graft materials for alveolar ridge augmentation, socket preservation, and maxillary sinus graft in some cases. In most cases, the impacted third molars of their children were prepared as bone graft material and were used for surgery. In one case, the impacted third molar from the patient's brother was used as bone graft material. We obtained satisfactory result and these cases are reported herein.

Purpose: The purpose of this study was to evaluate the histological healing process of 3 different types of xenogenic tooth bone graft material and xenogenic bone graft material. Methods: Three types of human tooth bone graft material (chips, crowns, and roots) and BioOss (Geistlich Pharma AG, Wolhausen, Switzerland) was filled at the preformed 4 round-shaped calvarial bone defects of beagle dogs. The beagles were sacrificed at 2, 4, 8, and 12 weeks, respectively, for radiological and histological evaluation. Results: Increased strength and radiopacity were detected in all graft material groups in time-dependent manner. New bone was formed and matured surrounding the graft material histologically. Also, a new bone was directly integrated with graft material. Conclusion: It was expected that newly developed tooth bone graft material would show good bone healing capacity if it was used as a graft material for the restoration of bony defect.

Autogenous tooth bone graft material contains organic and inorganic components for osteoinductive and osteoconductive healing. The clinical availability and safety of this material have been confirmed by various experimental and clinical studies. In the future, allogenic and xenogenic tooth bone graft materials, ideal scaffold using teeth for stem cells and bone growth factors, and endodontic and tooth restorative material will be developed.

Objectives: Interest in bone graft material has increased with regard to restoration in cases of bone defect around the implant. Autogenous tooth bone graft material was developed and commercialized in 2008. In this study, we evaluated the results of vertical and horizontal ridge augmentation with autogenous tooth bone graft material. Materials and Methods: This study targeted patients who had vertical or horizontal ridge augmentation using AutoBT from March 2009 to April 2010. We evaluated the age and gender of the subject patients, implant stability, adjunctive surgery, additional bone graft material and barrier membrane, post-operative complication, implant survival rate, and crestal bone loss. Results: We performed vertical and horizontal ridge augmentation using powder- or block-type autogenous tooth bone graft material, and implant placement was performed on nine patients (male: 7, female: 2). The average age of patients was $49.88{\pm}12.98$ years, and the post-operative follow-up period was $35{\pm}5.31$ months. Post-operative complications included wound dehiscence (one case), hematoma (one case), and implant osseointegration failure (one case; survival rate: 96%); however, there were no complications related to bone graft material, such as infection. Average marginal bone loss after one-year loading was $0.12{\pm}0.19$ mm. Therefore, excellent clinical results can be said to have been obtained. Conclusion: Excellent clinical results can be said to have been obtained with vertical and horizontal ridge augmentation using autogenous tooth bone graft material.

The extracted right mandibular third molar of a 37-year-old man was transplanted into the first molar area, and a bone graft procedure using autogenous tooth-bone graft material was performed for the space between the root and the alveolar socket. Reattachment was achieved after 10 months. Therefore, autogenous tooth-bone graft material is considered reasonable for bone induction and healing in the autotransplantation of teeth.

Purpose: To report the successful results of using chin bone graft and autogenous tooth bone graft material (AutoBT) in alveolar cleft patients. Materials and Methods: Five patients with alveolar cleft defects underwent alveolar bone grafting. Three patients were treated using chin bone graft, and the other two patients underwent AutoBT graft. After implant site development using chin bone graft in the fi rst three cases, endosseous implant restorations were placed. In case #4 and 5, AutoBT graft material was placed to guide the normal eruption of partially impacted maxillary right canine and to the upper docking site after distraction osteogenesis. Result: Successful implant restorations with closure of the oronasal fistula were achieved in alveolar cleft defect reconstruction using either chin bone graft (Case #1, 2, 3) or AutoBT graft material (Case #4, 5). Case #4 showed enlarged follicle of the right maxillary canine, indicating a normal eruption guide pattern. Conclusion: Both chin bone graft and AutoBT graft showed favorable outcomes in reconstructing alveolar cleft defects. Autogenous tooth bone graft opens up the possibility of avoiding harvesting autogenous bone graft with complications and morbidities.

Although many bone graft materials have been developed, powder graft materials are somewhat difficult to use in surgery. To solve this problem, a bone graft material in the form of a viscous paste was prepared. Hydroxyapatite was used as a bone graft material, and methyl cellulose was used to impart viscosity. Three cases of samples were prepared, and freeze-dried block type and sintered specimens were made from the paste. The recrystallization of the graft material in a simulated body fluid and the degree of graft adhesion with a tooth were observed by scanning electron microscopy (SEM). The test for cytotoxicity was carried out and the sample was grafted into the back of a mouse to confirm the presence or absence of side effects in the animal's body. Based on these investigations, composites of this type are expected to be applicable for bone grafts.

The author have been conducting research on the development of biomaterials using human teeth since 1993, and we recently reported the results of several of our advanced studies. Based on previous studies, new bone graft material using autogenous tooth(AutoBT) was developed. The author performed implant placement combined with GBR and sinus bone graft using AutoBT during the period of June 2009 to September 2009. During the postsurgical healing period, clinical and radiological evaluations were performed. For patients who consented to histological testing, tissue samples were obtained and histological examination was performed two months and four months after GBR and four months after sinus bone graft. Serious complications pertinent to bone graft materials were not observed, and it was shown that the level of the crestal bone in the vicinity of implants was relatively well maintained. In histologic examination after two months and four months, favorable new bone formation was observed.

The experimental assessment of autogenous tooth bone graft material (AutoBT) was conducted. Several studies on autogenous tooth bone graft material have confirmed the resorption of AutoBT over time and the formation of high-quality new bone.

Micromorphometric and histological examinations were conducted with a collected tissue specimen nine months after sinus bone graft using autogenous tooth bone graft material (AutoBT). As a result of micro-computed tomographic analysis, the total bone volume (graft material+new bone) was 76.45%, and the proportion of new bone was 45.4%. The bone mineral density and the average Hounsfield Unit of new bone were 0.26 and 1,164.69, respectively. The histological examination showed that AutoBT particles were united well with new bone. AutoBT was considered to have excellent bone healing ability after sinus graft and bone density that can resist repneumatization.
