J Korean Assoc Oral Maxillofac Surg 2012;38:221-30) Objectives: This study sought to evaluate the efficacy of collagen graft materials, as compared to other graft materials, for use in healing calvarial defects in rabbits. Materials and Methods: Ten mm diameter calvarial defects were made in ten rabbits. The rabbits were then divided into 4 groups: control, autogenous bone graft, SureOss graft,...

Bone marrow-derived cells including osteoblastic progenitors can be concentrated rapidly from bone marrow aspirates using the surface of selected implantable matrices for selective cell attachment. Concentration of cells in this way to produce an enriched cellular composite graft improves graft efficacy. The current study was designed to test the hypothesis that the biologic milieu of a bone ma...

Although various techniques have been described for treatment of severe nose deformities, these problems have high revision rates.  Conventional nasal septal surgery may not be adequate for all cases. A 21-year-old male patient with nose deformity underwent a nasal surgery. Patient had both functional and aesthetic nasal problems. Rigid fibular bone graft was used for corrective nasal ...

INTRODUCTION Autogenous iliac crest bone graft continues to be the material of choice for posterolateral lumbar intertransverse process spine fusion. However, continued interest lies in developing bone graft alternatives that can be used as either graft extenders, graft enhancers, or graft substitutes. It was the purpose of this study to evaluate the efficacy of a demineralized bone matrix/ hya...

Tendon-bone incorporation of a tendon graft within the bone tunnel is a major concern when using a tendon graft for ligament reconstruction. Successful anterior cruciate ligament (ACL) reconstruction with a tendon graft requires solid healing of the tendon graft in the bone tunnels. Improvement of graft healing to bone is crucial to facilitate early and aggressive rehabilitation and a rapid ret...

Anterior calcaneal osteotomy (ACO) with extension bone graft is commonly employed in the treatment of symptomatic supple, hypermobile flatfoot in adolescent as well as adult (>or= 18 years of age) patients. Although autogenous bone graft has been considered the gold standard, allogenic bone is widely used for this procedure because it is readily available, requires no additional procedure for p...

A micro-computed tomographic (muCT) analysis of bone healing subsequent to graft (tri calcium phosphate/TCP) placement in the maxillary sinus prior to dental endosteal implant placement was the focus of the current study. Ten trephined rod shaped human bone cores were obtained three months after the placement of particulate graft material. Using the muCT, samples were evaluated at 6 and 20 mum ...

PURPOSE Although there are a number of bone replacement graft materials that are currently available for clinical use, there are few studies that directly compare efficacy among graft treatments before implant placement. The purpose of this report was to compare 3 bone replacement graft materials (PepGen P-15 228 FLOW [DENTSPLY Friadent CeraMed, Lakewood, CO], Puros [Zimmer Dental, Carlsbad, CA...

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...
