Double-up Technique for Correction of Ridge Contour Deficiencies.

Implant site preservation has become standard treatment for the management of extraction sites to avoid or limit alveolar ridge atrophy following tooth extraction. Multiple techniques and materials have been utilized because of their ability to enhance bone healing and bone-forming capacity in extraction sockets and maintain alveolar ridge dimension for optimal implant placement. This article describes a novel method of contour ridge augmentation using a ribose-based cross-linked multilayered dual soft- and hard-tissue absorbable scaffold that also yields exceptional dental implant esthetics.

Surgical Treatment of Peri-implantitis with Guided Bone Regeneration Using Dehydrated Amnion-Chorion Membranes: A Case Report with a 2-Year Follow-up.

Peri-implantitis is an increasingly prevalent condition that, if left untreated, can lead to implant failure and loss. Numerous regenerative treatment modalities have been reported in the literature with varying degrees of success. Unfortunately, there is little consensus regarding optimal methods for predictable regeneration of the peri-implant bone lost due to the disease.

Horizontal Guided Bone Regeneration Using a Dehydrated Amnion/Chorion Membrane: A Case Report.

This article describes a novel approach for horizontal guided bone regeneration (GBR) using a dehydrated amnion/chorion membrane (dHACM) in conjunction with a composite mixture of cortical autogenous particulate bone scrapings and mineralized bovine bone particulate in the anterior maxilla, allowing for placement of dental implants in a previously deficient alveolar ridge. The grafted region was reentered 8 months after GBR surgery, and a substantial increase in horizontal bone width was observed. Endosseous dental implants were placed with excellent primary stability in a prosthetically driven manner (which could not have been done prior to GBR) and successfully restored with a screw-retained bridge prosthesis.

Treatment of Gingival Fenestration With a Double Pedicle Flap Approach and Dehydrated Amnion-Chorion Membrane: A Case Report.

Introduction: Although gingival fenestrations (GFs) occur with relative infrequency, their actual incidence is thought to be much higher. Furthermore, if left untreated, these mucogingival defects can lead to unfavorable sequelae which can compromise the esthetics and stability of the teeth affected. Most GFs require surgical treatment for closure.

Characterization of patients presenting for treatment to a university refractory periodontal diseases unit: three case reports.

Background: Of the many forms of periodontal disease, refractory periodontal diseases are the least characterized. They are defined as the continued degeneration of the periodontium despite adequate management. This has led to the suggestion that there may be a systemic component that is a contributing factor to the development of this condition.

Collagen phagocytosis by fibroblasts is regulated by decorin.

Decorin is a small, leucine-rich proteoglycan that binds to collagen and regulates fibrillogenesis. We hypothesized that decorin binding to collagen inhibits phagocytosis of collagen fibrils. To determine the effects of decorin on collagen degradation, we analyzed phagocytosis of collagen and collagen/decorin-coated fluorescent beads by Rat-2 and gingival fibroblasts.
