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.
This study was carried out in AL-ASSAD and Tishreen University Hospitals during
the years 2013-2015, and included 174 patients who have been treated. Male: Female ratio
was 1:2, and the average age of the sample of patients was 63. Great saphenous
vein
(medial) and internal thoracic artery Were used as grafts. analyzes blood values were
normal in all patients before surgery. after surgery it has never been transfer platelets in the
case of the beating heart .In the open-heart the average transfer platelet in patients was
(0.23), the average amount of bleeding into Drainage in the beating heart surgeries was
(902 ml) and was in the open-heart (1279 ml), the number of patients bled and the chest
was opened again because of bleeding was (14 patients) it is (8%) of total patients ,
prolonged ACT was the most important cause of the bleeding with rate (64.2%), the
percentage of patients who had Tamponade was (42.8%), the using of CPB more than 100
minutes has the greatest impact of bleeding with rate (78.5) .
This study aimed to study changes in subantral bony height when sinus membrane was elevated 6 mm without bone grafts depending on Cone Beam CT imaging.
The study sample contained 18 implants placed on 11 patients of
both genders, each patient under
went lateral-approach sinus-lift
without bone grafts and implants were inserted simultaneously and
protruded 6 mm under the elevated sinus membrane.
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 .
Surgical management of septum perforation considers challenge for surgeons
,as a lot of them hesitate before doing these operations because the high rate falling of previous traditional
surgeries for nasal septum perforation .
This study aims to e
valuate modern surgical technique using an implant of thin ( mashed) cartilaginous
piece coverd by two opposite mucous pericondrial flaps in both sides in order to close the septum
perforation .
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.
Chin area is considered as a suitable donor site for autogenous bone grafts for
alveolar ridge reconstruction before dental implantation, using large trephine bur(10mm) considers one of
several ways which appeared for bone graft harvesting. The aim
of this search is to study radiographic
density changes following chin bone harvesting for dental implantology by using large trephine bur
depending on digital panoramic radiographs.
Chin area is considered as a suitable donor site for autogenous
bone grafts for alveolar ridge reconstruction before dental implantation.
Despite the common use of chin bone grafts, some neurosensory deficiency
of the of the lower lip, chin area ,
gingiva and lower anterior teeth may
occur.
Purpose: Evaluation of neurosensory deficiency of the lower lip, chin area ,
gingiva and lower anterior teeth following chin bone harvesting for
posterior mandibular alveolar ridge reconstruction.
