Abstract

Regenerative therapies with platelets have been widely used in medicine over the past two decades as a means to speed revascularization to damaged/defective tissues. Within the oral cavity, the sinus is one of the least vascularized areas with healing times typically increased to augment lost or missing bone. As a result, attempts have been proposed to combine platelet concentrates with various biomaterials to accelerate new blood flow to these tissues and ultimately facilitate new bone regeneration. While platelet-rich plasma (PRP) was introduced as a first-generation platelet concentrate, more recently platelet-rich fibrin (PRF) has been developed with anticoagulant removal from centrifugation protocols. Unlike PRP, PRF forms a fibrin clot that may further be utilized as a 3-dimensional scaffold containing a concentrated pool of autologous growth factors for tissue regeneration. Over the past decade, PRF has been used both as a sole grafting material and in combination with a bone graft for sinus augmentation procedures. This article highlights the biological and clinical advantages of using PRF with or without a bone grafting material for sinus augmentation procedures and provides guidelines detailing when, where, and why to...Continue Reading

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
