Bone transplantation is often used for the reconstruction of defects. The best results are achieved with autogenous grafts because they induce no immunological reaction, but allogeneic grafts from bone banks are frequently used to provide an adequate volume of bone (Cookson et al 1988). In Germany, about 470 departments using such banks perform about 71 000 autogenous and about 25 000 allogenei...

A pleasing smile involves a harmonious relationship among the teeth, the gingival scaffold and the lip framework. In dental profession, aesthetics of the patient is the main factor to be focused on along with treating the disease of the patient. The primary goal of esthetic dental treatment is the restoration to a natural, healthy, and esthetic appearance from an otherwise damaged dentition [1]...

PURPOSE To review the radiology and histology of synthetic bone grafts resected from patients with recurrent giant cell tumour (GCT) of bone. METHODS 22 patients underwent curettage and grafting for GCT of bone using autogenous cancellous bone mixed with apatite-wollastonite-containing glass ceramic (AWGC), hydroxyapatite (HA), or a mixture of HA and tricalcium phosphate (TCP). Patients were ...

INTRODUCTION Prosthetic arteriovenous (AV) grafts are indicated in patients with failed AV fistula (AVF), exhausted superficial veins or unsuitable vessels. Increasing the proportion of prevalent hemodialysis (HD) patients using autogenous AVF should reduce the need for AV grafts and associated morbidity. This paper reviews the current role of prosthetic AV grafts in vascular access for HD. T...

The aim of this study was to determine the efficacy of a bioresorbable collagen membrane (Bio-Gide) in combination with autogenous bone grafts in the treatment of peri-implant dehiscences, fenestrations, or limited vertical defects. Eighteen titanium dental implants with exposed threads placed in 17 patients were studied. Autogenous bone was used in all cases to fill the defect and maintain the...

Mandibular fractures have a high incidence among facial bone fractures that necessitated prompt treatment. The use of autogenous graft as a fixation device for mandibular fracture may have an important role in bone healing with accepted biological effect, and normal bone growth especially in pediatric patients. Moreover it avoids the side effect of both inter maxillary fixation (IMF) and bone p...

A 19-year-old female patient visited our clinic for rhinoplasty. She complained about her low take-off point, which was apparent in profile view, and wanted slight tip projection. She refused additional cartilage harvesting from ears or ribs but consented to the use of homologous tissue, including acellular dermal matrix, for her dorsum and tip. Septoturbinoplasty was performed, and only a very...

The aim of this study was to evaluate the resorption process during the repair of autogenous bone grafts with or without coverage by an expanded polytetrafluoroethylene (e-PTFE) membrane in female rats with estrogen deficiency using the immunohistochemical technique. Eighty female rats were randomly divided into two groups (OVX and SHAM). The 40 female rats in the OVX group were subjected to ov...

PURPOSE To evaluate the effect of platelet-rich plasma (PRP) on autogenous bone graft remodeling during sinus augmentation in a rabbit model. MATERIALS Twelve New Zealand White rabbits were divided randomly into 3 groups based on their time of sacrifice (2, 4, and 8 weeks). All animals underwent a general anesthetic and harvesting of an autogenous bone graft from the right iliac crest with su...
