Introduction: Coverage of bone grafts is very important in reconstructive surgery. In edentulous alveolar ridges this coverage is particularly important for supporting dental prostheses. Here we present the case of a patient with a large deficient maxillary anterior region that was reconstructed with a bilateral palatal submucosal periosteal connective tissue flap: a soft tissue reserve for up...

OBJECTIVE This study investigated the role of occlusion in the development of biomechanical properties of alveolar bone in the miniature pig, Sus scrofa. The hypothesis tested was that the tissues supporting an occluding tooth would show greater stiffness and less strain than that of a non-occluding tooth. DESIGN Maxillary teeth opposing the erupting lower first molar (M(1)) were extracted on...

BACKGROUND Porphyromonas gingivalis has been shown to invade osteoblasts and inhibit their differentiation and mineralization in vitro. However, it is unclear if P. gingivalis can invade osteoblasts in vivo and how this would affect alveolar osteoblast/osteoclast dynamics. This study aims to answer these questions using a periodontitis mouse model under repetitive P. gingivalis inoculations. ...

PURPOSE To study were to reproduce an alveolar bone defect model in Wistar rats to be used for testing the efficacy of stem cell therapies. Additionally, we also aimed to determine the osteogenesis process of this osseous defect in the 1 month period post-surgery. METHODS The animals were randomly divided into two groups of 7 animals each. A gingivobuccal incision was made, and a bone defect ...

PURPOSE This randomized clinical trial was conducted to assess the safety and effectiveness of the ErhBMP-2 in alveolar bone regeneration as well as preservation of the β-TCP bone graft material that contains ErhBMP-2. MATERIALS AND METHODS This study involved 72 patients at the 3 study centers. The patients, who were divided into 2 groups: the experiment group who had ErhBMP-2 coated TCP/HA ...

Rehabilitation of the atrophied edentulous maxilla is complicated. Often the residual bone height is insufficient for implant placement due to crestal bone resorption and pneumatization of the sinus.The meticulous management of the available residual bone, the atraumatic sinus lifting procedure, and the proper selection of the implants are the keys to successful dental implantation in resorbed ...

The purpose of this paper is to discuss the management of the cleft maxilla with emphasis on the controversies concerning the decisions which a cleft palate team makes with limited evidence but strong beliefs in the anticipated outcomes. The orthodontist and the surgeon need to collaborate in determining the timing and sequencing of alveolar bone grafting. Currently the emphasis on secondary bo...

AIM To identify by ultrasonography (DermaScan C, Cortex Technology1) the reference points necessary to monitor the horizontal bone resorbtion and to assess the accuracy of the measurements by comparing with Cone Beam Computed Tomography images, having direct microscopic section measurements as a gold standard. MATERIAL AND METHODS We performed the examinations on the lingual side of the alveo...

Periodontal disease is one of the most common infectious diseases of humans. Immune responses to infection trigger loss of alveolar bone from the jaw and eventual tooth loss. We investigated the contribution of B cell IgD to alveolar bone loss by comparing the response of B cell normal BALB/cJ mice and IgD deficient BALB/c-Igh-5(-/-J) mice to oral infection with Porphyromonas gingivalis, a gram...
