PURPOSE Use of a composite graft combining a polytetrafluoroethylene graft with an autogenous vein is an option for limb salvage in the absence of an adequate single segment vein graft. We aimed to investigate the results of infrainguinal bypass with a composite graft. MATERIALS AND METHODS We retrospectively reviewed 11 infrainguinal arterial bypasses on 11 limbs which underwent surgery from...

INTRODUCTION: Lower eyelid retraction is a common but challenging complication following blepharoplasty. A wide array of techniques has been described to address this problem including the use of posterior lamellar spacer grafts. No consensus exists on the best available spacer graft material. We performed a systematical review of studies comparing efficacy and complication rates among various ...

OBJECTIVE Moldable in situ self-stabilizing and hardening bone graft materials facilitate handling and may be suitable for membrane-free bone regeneration methods. This study aimed to compare two moldable synthetic calcium phosphate materials in a rabbit calvarial defect model. METHOD In 12 New Zealand white rabbits, four evenly distributed 6 mm diameter defects were drilled in the calvarial ...

This article is limited to a review of bone replacement graft materials used in periodontal therapy. The source, mode of bone regeneration and the respective advantages and disadvantages of autogenous, allogenic, xenogenic and alloplastic materials are discussed.

conclusions alendronate may be considered a therapeutic option for improving the bone formation process and reducing resorption in different bone grafting procedures. further detailed studies should focus on dosage and time-dependent effects of alendronate on bone remodeling. results at 6 weeks, the bone area was significantly larger in the xenograft-alendronate group (33.0% ± 5.0%) than in the...

Treatment of delayed union, malunion, and nonunion is a challenge to the orthopaedic surgeons in veterinary and human fields. Apart from restoration of alignment and stable fixation, in many cases adjunctive measures such as bone-grafting or use of bone-graft substitutes are of paramount importance. Bone-graft materials usually have one or more components: an osteoconductive matrix, which acts ...

We present an overview of the current literature and management techniques for vaginal extrusion or urinary tract erosion of graft materials used in pelvic floor reconstruction. A MEDLINE search was performed to identify literature pertaining to the incidence and management of vaginal or urinary tract exposure of graft materials commonly used in anti-incontinence and pelvic floor reconstructive...

introduction: nowadays the necessity of the existence of a certain width of keratinized gingiva is emphasized upon to maintain periodontal health and prevent soft tissue recession around teeth and dental implants. this study was carried out to compare two gingival graft procedures including connective tissue graft and graft with a combination of collagen sponge with platelet-rich plasma and pla...
