BACKGROUND We recently demonstrated that a 2-year subantimicrobial-dose doxycycline (SDD) regimen (double-masked, placebo-controlled clinical trial) in postmenopausal (PM) women exhibiting mild systemic bone loss (osteopenia) and local bone loss (periodontitis) reduced the progression of periodontal attachment loss (intent-to-treat analysis) and the severity of gingival inflammation and alveola...

Alveolar preservation can minimize bone resorption after tooth removal and additional topical antibiotics might also be considered. The goal of this study was to observe alveolar with albumin gentamycin-coated allograft compared unfilled control sockets mandibular third molar removal. Twenty-two patients were involved, 11 in the group test group. CBCT analysis micromorphometric performed. After...

The aim of the present study was to evaluate the clinical efficacy of platelet-rich fibrin (PRF) in preserving the alveolar ridge following human tooth extraction. A total of 28 patients were divided into two groups: The experimental and control groups (n=14 each). Following tooth extraction, the experimental group was implanted with PRF membrane, whereas the control group was not. The gingival...

Periodontal diseases are chronic inflammatory diseases that can result in resorption of the alveolar bone of the jaw. We have developed a murine model in which alveolar bone loss is induced by oral infection with Porphyromonas gingivalis, an oral anaerobic bacterium associated with periodontal disease in humans. Here we compared a strain of immunocompetent mice (C57BL/6J) to the same strain of ...

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 ...

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...

BACKGROUND Jaw bone and iliac bone are the most frequently used autologous bone sources for dental implant placement in patients with atrophic alveolar ridges. However, the comparative long-term stability of these two autologous bone grafts have not yet been investigated. The aim of this study was to compare the stability of simultaneously placed dental implants with autologous bone grafts harv...

Post-extraction crestal bone resorption is common and unavoidable which can lead to significant ridge dimensional changes. To regenerate enough bone for successful implant placement, Guided Bone Regeneration (GBR) is often required. GBR is a surgical procedure that uses barrier membranes with or without particulate bone grafts or/and bone substitutes. There are two approaches of GBR in implant ...
