من المشاكل التي قد تواجه الجراحين تغير حجم الطعوم الحرقفية المستعملة في تطعيم الفقدان العظمي في العظم السنخي و ذلك بسبب الامتصاص الذي يحدث في هذه الطعوم خلال شفائها و تحولها إلى عظم بشكل كامل. هدفت هذه الدراسة لاجراء مقارنة بين الطعوم المأخوذة من الحرقفة على شكل قطعة عظمية block bone graft بواسطة السنابل الاسطوانية المجوفة Trephine و بين الطعوم العظمية التي يتم الحصول عليها بواسطة المكاشط العظمية bone scraper، حيث تألفت عينة الدراسة من 10 مرضى من الذكور من المراجعين لمشفى جراحة الوجه و الفم و الفكين في كلية طب الأسنان جامعة دمشق في الفترة الزمنية بين 2010-2012 م، و كان المرضى يعانون من ضمور واضح في مناطق الارتفاعات السنخية العلوية و السفلية لأسباب عديدة و بحاجة لتطعيم عظمي لتعويض هذا الفقدان و تحقيق المكان المناسب لاستقبال الزرعات السنية. لوحظ تحقق الالتحام العظمي في الطعوم العظمية الحرقفية و تحولها بشكل كامل إلى عظم طبيعي، و لكن كانت الطعوم الحرقفية القطعية محافظة على حجمها بشكل أكبر من الطعوم العظمية المأخوذة بالمكشط العظمي. استعمل اختبار Mann-Whitney U و البرنامج الحاسوبي SPSS لتحليل البيانات، حيث أظهرت النتائج أنه عند إعادة الترميم العظمي لمناطق الضمور باستعمال الطعوم الحرقفية القطعية فإن هذه الطعوم لم تتعرض للامتصاص كما هو الحال عند استعمال الطعوم العظمية المأخوذة بالمكشط العظمي، و لكنها كانت تتعرض إلى الانكشاف و تراجع اللثة حول حواف الطعم بشكل تالٍ للعمل الجراحي مع أفضلية واضحة للطعوم المأخوذة بالمكاشط العظمية عليها في هذا الجانب.
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 .

The aim of this study is to evaluate the combination of
autologous factors, platelet rich fibrin (PRF), with bone grafts,
beta tricalcium phosphate (βTCP), In Improving the Prognosis of
Surgical Treatment of periapical lesions .
Non Vascularized fibular Bone Grafts are consider one of the most method
which used in limp sparing surgery.
This study aims To knowledgement the early and later complications of the Non Vascularized fibular
grafts in bone reconstruction following
bone tumor resection.
the retrospective study was performed at 40 patients with malignant and benign
tumors, the study lasted from January 2007 to January 2011. during this period 40 surgical operation
were performed. This study depends on the arshef of bone Tumors unit- Albairouni hsspital.
The need to repair dentoalveolar atrophy and bone defects has resulted in
developing techniques and sources of graft materials، and the use of autogenous bone grafts continues to
represent the ‘gold standard’ in reconstructive surgery of the oral a
nd maxillofacial region.
This study aims to assessment the complications of autogenous bone harvesting from retromolar region of
mandible by trephine burs.
Soft laser applications continue to improve local bone mineral density which is considered the most important factor in dental implant success.
This study aims to evaluate the Trabecular to Cortical bone ratio (TCr) index -as a simple easy measureme
nt index- that expresses the bone mineral density. This is to be able to predict the success of dental implants.
The study included 40 patients, who had a single implant in the lower molar region. The patients are divided into two groups: 20 patients had an implant with a soft laser application, i.e. GaAlAs laser (wavelength 830 nm), and 20 patients had an implant without a soft laser application.
Ordinary Analog periapical radiographs were used with calibration Stepwedge of pure aluminum, a medical Dijora program was used to measure radiographically local bone density in the periapical radiographs, and a panoramic Tomography was made to study TCr and two bone density indices (thickness ratio x density ratio) and (equivalent Aluminium thickness). All were measured during the period before implantation and 3, 6, and 9 months after the implantation.
The study found a strong linear correlation between the TCr and (thickness ratio x density ratio) 0.001>P, R2= 0.842 36(r = 0.8. and equivalent Aluminium thickness(
0.001> P, R2 = 0.656735, (r = 0.8).
The study shows that TCr index expresses both radiographic indices which reflect the local bone density, which means that the TCr is associated with such density. Therefore, it can be used as an easy way to predict the quality of bone, and prognosticate the success of dental implants.
Our present study aimed at evaluating vertical resorption
following ramus and chin grafts applied in the split space after sixmonth
implant delay.
