  • 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.

  • 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.

  • Class I malocclusion is essentially a dental dysplasia. Rotations, individual tooth malpositions, missing teeth, tooth size discrepancies, etc., fall under this classification. There are two types of class I malocclusions. One is identified by and insufficient denture base to accommodate the teeth; the other has more denture base than tooth material, creating spaces in the arch. The tooth material-to denture base discrepancies may be slight, calling for only a little increase in arch length for alignment and the correction of minor rotations. Discrepancies may also be great, in which case it becomes necessary to reduce tooth material by extraction, so as to make the tooth material more in proportion to the size of the denture base. The author had attempted orthodontic treatment of a class I malocclusion case of 13-year old boy in which high canines and impacted mandibular second premolars were involved. The author obtained good results.

  • 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.

  • This study evaluated the mineral crystalline structure of an autogenous tooth bone graft material. The crystalline structures of the autogenous tooth bone graft material enamel (AutoBT E+), dentin (AutoBT D+), xenograft (BioOss), alloplastic material (MBCP), allograft (ICB) and autogenous mandibular cortical bone were compared using XRD. The XRD pattern of AutoBT dentin and ICB was similar to that of autogenous bone.

  • 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.

  • In this research, a material test machine is developed which uses a small electro-magnetic actuator and a leverage mechanism. The leverage mechanism amplifies the force from the electro-magnetic actuator. The electro-magnetic part operates more silently and cleanly than a hydraulic part. In a tooth material study, a test machine does not require a large force capacity because it handles only $4mm^2$-sectioned and short-span specimens. Conventional test machines such as those by Instron and the BOSE Enduratec ELF3200 have too high aforce capacity for a tooth material study. A test machine for a tooth material study requires an acting force only on the order of tens of Newtons (N) operating at several Hertz.

  • A study was conducted to investigate the possibility of a composite material containing a composite resin as a matrix and hydroxyapatite (HAp) powder as a substitute material for tooth repair. As the content of HAp increased, hardness value (111.9 HV at 9%) increased and flexural strength (73.3 MPa at 9%) decreased. Observation of the microstructure after immersion in a simulated body fluid (SBF) solution confirmed a dense structure due to mutual coagulation and curing. It was thought that fine HAp recrystals were formed with the lapse of time, and they were entangled to form a condensation structure and had a dense structure. In addition, since the activity was shown by the ion migration on the surface of a tooth, it was highly likely that a biocompatible bond occurred during tooth contact. Therefore, it could be used as a substitute material for tooth repair.

  • A study for investigating the effects of the cutting conditions (radial depth of cut feed per tooth) and the number of tooth on the side wall of prismatically milled workpiece is described. This study is available not only for understanding the geometrical characteristics of the end milled side wall but also for finding the optimal cutting conditions. In this work, the side wall geometry was characterized by the straightness and the location of maximum peak point. Through this study, it was revealed that the geometrical characteristics of the end milled side wall are strongly related to the material removal per tooth and the number of tooth.

  • 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.
