PURPOSE The purpose of the present study was to evaluate the histologic results of bone cavities that were surgically created in the mandibles of Cebus apella monkeys and filled with autogenous bone, PerioGlas, FillerBone, or Bone Source. MATERIALS AND METHODS Surgical cavities 5 mm in diameter were prepared through both mandibular cortices in the mandibular angle region. The cavities were ra...

autogenous tooth transplantation (att) can be considered when there is a hopeless molar tooth and suitable donor present. this report presents an unconventional case of successful att of a third molar replacing the adjacent fractured second molar in a 33 year old woman. this wisdom tooth had completely developed roots. root-end filling with calcium enriched mixture (cem) cement was performed in...

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...

Conventional surgical procedures designed for autogenous tissue material may not be appropriate when using acellular dermal matrix (ADM) for the treatment of gingival recessions. This article describes a new surgical technique that addresses the unique and sensitive aspects of ADM specifically to improve esthetic outcomes and gain increased clinical predictability when treating Miller Class I a...

Purpose: The purpose of this retrospective analysis was to evaluate the medium-term results of arthroscopic treatment of chondral and osteochondral lesions of the knee with autogenous osteochondral transplantation (AOT). Type of Study: Case series. Methods: Thirty-three skeletally mature patients with symptomatic, full-thickness cartilage lesions of the femoral condyles, between 1 and 2.5 cm in...

In the supersymmetric seesaw model of neutrino masses, augmented by the nonAbelian discrete tetrahedral symmetry A4, a specific pattern of neutrino mixing is automatically generated if one of the three heavy singlet neutrino superfields acquires a nonzero vacuum expectation value. This pattern turns out to be exactly that of tribimaximal mixing, i.e. sin θ23 = 1/2, sin 2 θ12 = 1/3, and sin 2 θ1...

Self-healing concrete (SHC) has received a tremendous attention due to its advanced ability of automatic crack detection and crack repairing compared to the standard concrete. Two main approaches which considered as to-date self-healing mechanisms are autogenous and autonomous healing. In the past several years, the effort of the research has been focused on experimental works instead of numeri...

We described a new technique (called ‘bicuspidization’), which is performed by using autogenous material, without replacement of the aortic valves for the surgical treatment of aortic stenosis and/or insufficiency and tested it in in vitro sheep model. Different stress conditions were simulated by applying three different flow patterns (hemodynamic challenge tests) successively by using a centr...

Methods: A field trial was conducted on one group of nursery pigs (N=330). Pigs were randomly allocated to one of four groups that each received one of the following treatments at weaning: an experimental autogenous vaccine administered intramuscularly (IM) (n = 90); a standard autogenous vaccine administered IM (n = 90); a commercial bacterin, administered intraperitoneally (IP) (n = 60); or n...

We treated 15 patients with atrophic nonunion of a diaphyseal fracture of the humerus with an associated bony defect using an autogenous cancellous bone graft and a plate to bridge the defect. There were nine men and six women with a mean age of 48 years. The mean length of the bony defect was 3 cm. At a mean follow-up of 30 months only one fracture failed to unite. This suggests that, in the p...
