Implants were placed after performing ridge expansion by inserting screws of gradually increasing thickness. Favorable clinical outcome was obtained. During surgery, buccal cortical plate fracture did not occur. Autogenous tooth bone graft material was grafted around the implant dehiscence defects and over the buccal cortical plate. The method involving the insertion of screws for ridge expansion is a successful and predictable technique for implant placement in narrow alveolar bone. Autogenous tooth bone graft material can be used for ridge augmentation and GBR.

The aim of this study was to evaluate histomorphometrically and compare the efficiency of various bone graft material and autogenous tooth bone graft material which were used in sinus bone graft procedure. Subjects were the 24 patients who had treated with sinus bone graft using lateral approach from October 2007 to September 2009 at SNUBH. The average age was $52.51{\pm}11.86$ years. All cases was taken after 4month of procedure and divided into 3 groups according to bone graft material. Group 1: autogenous tooth bone graft material, Group 2: OrthoblastII(integra lifescience corp. Irvine, US)+Biocera(Osscotec, seoul, korea), group 3: DBX(Synthes, USA)+BioOss(Geistlich Pharm AG, Wolhusen, Switzerland). Total 37 implant placement area were included and evaluated(7 in group 1, 10 in group 2, 20 in group 3). Evaluation of new bone formation, ratio of woven bone to lamellar bone, ratio of new bone to graft material were performed on each tissue section. Kruskal-Wallis test was used for statistical analysis(SPSS Ver. 12.0, USA). New bone formation were $52.5{\pm}10.7%$ in group 1, $52.0{\pm}23.4%$ in group 2, $51.0{\pm}18.3%$ in group 3. There were no statistical significant differences between each groups. Ratio of woven bone to lamella bone were $82.8{\pm}15.3%$ in group 1, $36.7{\pm}59.3%$ in group 2, $31.0{\pm} 51.2%$ in group 3. Ratio of new bone to graft material were $81.3{\pm}10.4%$ in group 1, $72.5{\pm}28.8%$ in group 2, $80.3{\pm}24.0%$ in group 3. After 4 month of healing period, all group showed favorable new bone formation and around graft material and implant. Within limitation of our study, it is suggested that autogenous tooth bone graft material might be used as novel bone graft material for sinus bone graft.

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 authors installed implants combined with guided bony regeneration (GBR) using autogenous tooth bone graft material in the patients. In one patient, GBR and simultaneous implant placement were performed. In two patients, GBR was performed and the implants were placed after 6 months. All patients achieved favorable clinical outcomes. Excellent osteoconductive bony healing was observed in the 6 month histology examination after the bone graft.

Horizontal and vertical ridge augmentation with implant placement was performed, using a block type of autogenous tooth bone graft in a 37-year old male patient. This material was very useful for the case of severe alveolar bone resorption of a single tooth. After 13 months, excellent bony healing was obtained and final restoration was performed successfully.

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.
