Aim of the Study: To evaluate the changes to the radiographic
bone density of the mental bone grafts applied in terms of ring
technique until 18 months post operatively and to evaluate the
effect of the adjacency of neighboring teeth.
The objective of the present study was to investigate, in a sub-sinus
bone augmentation model in rabbits, effect of Three Calcium Phosphate
beta at different stages of the osteogenesis process. Histological and
statistical analyses were performed.
Rabbits underwent sinus augmentation procedures using Three Calcium
Phosphate beta (Cerasorb) and Collagen membrane ( Gen Derm ) .
The aim of this clinical study Was to Evaluation success
rate of the Bone Augmentation With Simultaneous Dental
Implantation using Autogenous Bone Block In Patients With
Atrophic Alveolar Ridges .
The study was contained 6 cases were augmented Wi
th
Simultaneous Dental Implantation by applying Autogenous
Bone Block technique The height and width was measured by
using computerized tomographic C T scan before and after
the surgical operation and also resorption after six months.
The common problem that may encounter surgeons were the change of the volume of iliac bone grafts which used in atrophic region in the alveolar bone because of the resorption of this grafts during healing period.
This study aimed to compare between
block graft which taken by surgical bur (trephine)and grafts which collected by bone scraper ,in this way the bone graft look like small chips .This study included 10 patients who presented the oral and maxillofacial department in dentistry faculty in Damascus university between 2010-2012 A.D. the patients suffered from sever atrophy in upper and lower alveolar bone for different underlying causes and needed to compromise these atrophy to create a suitable area for dental implantation .The iliac bone grafts were turned into a real bone in the grafted area but the block grafts were saving their volumes more than the grafts collected by bone scraper. We used Mann-Whitney U and SPSS to evaluate the data that collected during the research and the results revealed that the block iliac bone graft which used to compromise the atrophic region would resorb less than the grafts which collected by bone scraper . But these grafts showed that it would be more exposed after surgery than the bone scraper grafts .
Assessment the changes in chin morphology after harvesting bone graft from
the symphysis using cephalometric radiographs.
