: Onlay bone augmentation is a challenging field, especially in esthetic zones. In implant dentistry, labial bone loss is generally recovered through autologous bone and/or biomaterials. Dental pioneers have been applying a patient-own demineralized dentin matrix (DDM) for bone regeneration. The aim of this study was to histologically and radiologically evaluate horizontal bone augmentation on an anterior atrophic maxilla using an autograft of non-vital tooth-derived DDM for implant. A 56-year-old female patient presented with severe labial bone loss. Autologous DDM was immediately pre pared for horizontal ridge augmentation. DDM blocks were fixed with titanium screws for lateral augmentation. DDM gran ules were grafted on the atrophic bone between the DDM blocks. Twelve months postoperatively, bone biopsy was per formed from the implant placement point for histological observation. X-ray computed tomography (CT) was performed before and after the DDM graft surgery. Hematoxylin and eosin sections showed that new bones were directly generated on the DDM residue. CT images showed the original buccal bone lines and root-type and wall-type DDM. The grafted DDMs were clearly found on the original bone. The outlines in the 22nd region indicated an 8.11 mm horizontal width after the implant placements compared to 4.95 mm before the augmentation. Additionally, the width at the upper level increased from 3.38 mm to 5.92 mm. DDM scaffolds contributed to the horizontal bony support required to place the implants. The patient experienced therapeutic success with DDM immediate autograft and implant surgery.

: The dental panoramic radiographs (PR) and lateral cephalographs (LC) of 140 subjects in the age group between 5 and 24 years were examined to evaluate the mandibular morphology in relation to gender and age. The examined films were divided into seven age groups. The bigonial width (BW), mandibular body height (MBH) and length (MBL), mandibular ramus width (MRW), height (MRH) and length (MRL), and gonial angle were recorded, measured and the data analyz-ed. Level of significance was set at 0.05. In our study the mean value of BW and MRW increased in both gender with in creasing age up to age 17 years, then began decreasing. The anterior and posterior MBH and MBL increased with increasing age for both genders with statistically significant differences between the first and second groups ( p < 0.05) and the fourth and fifth groups ( p < 0.05) for anterior MBH, and between the third and fourth groups ( p < 0.05) for posterior MBH and MBL ( p < 0.05). MRH and MRL also increased with increasing age with statistically significant differences between the third and fourth ( p < 0.05) and the fourth and fifth ( p < 0.05) age groups for MRH and the fourth and fifth ( p < 0.05) and fifth and sixth ( p < 0.05) age groups for MRL. On the other hand, the gonial angle decreased with increasing age but without significant differences. Knowledge of mandibular growth is important factors for diagnosis and treatment planning in ortho dontics as well as community medicine for monitoring the growth of children.

: Vascularized autologous bone grafts are widely used for mandibular reconstruction. There have also been numerous reports of occlusal reconstruction by placement of implants in the grafted bone following reconstruction of the mandible. However, the histological structure of the bone used for the graft is different from that of healthy mandibular bone, and the osseointegration process of implants placed in grafted bone is not clear. In this study, implants placed in reconstructions using grafted bone were assessed by measuring the implant stability quotient (ISQ), and their values were compared to those from implants in healthy mandibular bone. The subjects were 5 implants placed in the sites of mandibular reconstructions with vascularized fibula flaps. The controls were 54 implants placed in the molar region of healthy mandibles. All im plant placements were carried out by a two-stage procedure, and the ISQs were measured at first-stage surgery and at sec -ond-stage surgery. The ISQ values thus obtained and the change in ISQ from first-stage surgery to second-stage surgery were examined statistically. There was no significant difference in the ISQ between the two groups at first-stage surgery, but the values of the ISQ and the change in ISQ were significantly greater in the mandibular reconstruction at second-stage sur gery. This appears to be the result of histological differences between the reconstruction site and the healthy bone. The ISQ is an objective index of osseointegration of the implant. The present results suggest that observing changes in ISQ over time allows investigation of the usefulness of different types of bone grafts for implant therapy.
