Background: Iliac osteotomies in adolescent patients may accompany graft related difficulties such as graft absorptionand delayed union. A new modification of iliac osteotomies has been proposed to address these difficulties.Methods: A total of 24 consecutive hip joints in 21 juvenile or adolescent patients who were candidate for salter ortriple pelvic osteotomy were included....

BACKGROUND Bone grafts are frequently used in orthopaedic surgery. Graft remodelling is advantageous but can occur too quickly, and premature bone resorption might lead to decreased mechanical integrity of the graft. Bisphosphonates delay osteoclastic bone resorption but may also impair formation of new bone. We hypothesize that these effects are dose dependent. In the present study we evaluate...

Background: Dural substitutes are commonly utilized to repair dural defects incurred during routine neurosurgical procedures. The ideal dura substitute should effectively seal the defect, encourage neoduralization, and regenerate native dura prior to graft resorption. Cerafix® Dura Substitute is a novel non-biologic, fully-resorbable graft that has previously been shown to successfully repair c...

Background: Secondary alveolar bone graft has been widely used for the closure of maxillary bone defects in patients with cleft lip and palate (CLP). However, the log-term stability of grafted bone in detail remains unclear. Purpose: To evaluate the nature of longitudinal changes in the grafted bone from autogenous iliac bone in patients with CLP for more than 2 years after the surgery. Methods...

Purpose. Bone atrophy after tooth loss may leave insufficient bone for implant placement. We compared volumetric changes after autogenous ramus block bone grafting (RBG) or guided bone regeneration (GBR) in horizontally deficient maxilla before implant placement. Materials and Methods. In this retrospective study, volumetric changes at RBG or GBR graft sites were evaluated using cone-beam compu...

Introduction: The bone volume maintenance is important for ideal esthetic and functional outcomes. Due to the resorption, there a loss of socket width three dimensionally resulting in narrowing shortening alveolar ridge contour. In present study we aim evaluate autogenous demineralized dentin (ADDM) graft formation new bone. Materials Methods: We compared 200 extraction sites with ADDM various ...

Alteration of the geometrical surface configuration of cortical bone allografts may improve incorporation into host bone. A porous biodegradable coating that would maintain immediate structural recovery and subsequently allow normal graft healing and remodeling by promoting bony ingrowth could provide an osteoconductive surface scaffold. We investigated the feasibility of augmenting cortical bo...

Background: Although, different grafts are used for nasal tip plasty in cases with under projected or ill defined tip, the selection of a graft material, which provides sufficient amount of tissue with least donor site morbidity and low recipient site complication is challenging. The objectives of the present study were to examine the usefulness of cartilaginous dorsum as a proper material for ...

BACKGROUND The purpose of the present study was to evaluate different types of maxillary pre-prosthetic surgery using autogenous bone graft and suggest a guideline for maxillary reconstruction to place implant. METHODS 181 patients (125 females and 56 males), age range from 16 to 76 years old, were operated at the Maxillo-Facial Service of the Lille's 2 Universitary Hospital Center (Chairman ...

background: alveolar ridge preservation could be performed immediately following tooth extraction to limit dimensional changes of alveolar process due to bone resorption. the aim of this study was to compare the clinical and histologic outcomes of socket preservation using two different graft materials; deproteinized bovine bone mineral (dbbm) and demineralized freeze‑dried bone allograft (dfdb...
