Vitoss Bone Graft Substitute
Vitoss Bone Graft Substitute is the #1 selling synthetic bone graft with over 425,000 implantations worldwide.1
The success of Vitoss Bone Graft Substitute is founded on proven results and experience, including numerous human clinical studies (including prospective and peer reviewed).2
Vitoss Bioactive Bone Graft Substitute combines the optimized design of standard Vitoss with a unique bioactive additive that facilitates faster bone remodeling. Vitoss BA2X Bone Graft Substitute, launched in 2011, contains increased levels of bioactive glass and has shown through in-vitro testing to induce two times the deposition of calcium phosphate onto the surface of the implant while retaining the same handling properties as Vitoss BA Pack.3
Vitoss and Vitoss Bioactive Bone Graft Substitute are intended to be used for filling bony voids or gaps of the skeletal system (i.e., the extremities, pelvis, and posterolateral spine), and may be used with saline, autogenous blood, and/or bone marrow.
Additional forms of Vitoss launched in 2012 include Vitoss BBTrauma, available in pack form, exclusively sold for trauma surgery and created with a greater specific surface area of bioactive glass than Vitoss Bioactive, and VitoMatrix, a resorbable, porous Beta-Tricalcium Phosphate bone graft material intended to fill, augment, or reconstruct periodontal or bony defects of the oral and maxillofacial region.
Features & Benefits
- Structure – Despite having similar chemistries, many products perform differently due to different structure. Vitoss has an open, interconnected structure that facilitates 3-D bone regeneration. 5
- Porosity – Only materials with interconnected porosity will allow for 3-D regeneration of bone as opposed to creeping substitution. 6 Additionally, increased porosity has been shown to lead to higher fusion rates. 6 Vitoss is a highly porous calcium-phosphate (up to 90% porous). 7
- Bioactivity 8– Bioactive glass has shown positive bonding-to-bone properties. 9-11 Upon implantation, the ionic constituents (Si+, Na+, Ca2+) of bioactive glass are released into the surrounding environment and react with the bodily fluids. 15-18 This reaction produces the deposition of a thin layer of physiologic CaP at it’s surface, thus attracting osteoblasts to the layer to create a matrix that promotes an osteostimulatory effect. 9-15 This may lead to the bonding of new bone to the scaffold.
- Chemistry - Chemistry affects the rate of resorption. Vitoss is composed of B-TCP and is stable at physiologic pH. It resorbs during the natural remodeling process of bone. Evidence suggests that B-TCP resorbs in the most relevant time frame. 19
Imbibe Bone Marrow Aspiration & Delivery (BMA)
The Imbibe product platform is a family of disposable single use products designed to harvest bone marrow in order to deliver an osteogenic and osteoinductive component to Vitoss bone graft, as well as to assist in the delivery of Vitoss to the surgical site.
The Imbibe products have been designed specifically to enhance the clinical utility of Vitoss Bone Graft Substitute for the surgeon, and to facilitate the aspiration of bone marrow.
Vitoss Bone Graft Substitutes are intended for us as bone void fillers for voids or gaps that are not intrinsic to the stability of the bony structure. Vitoss Bone Graft Substitutes are indicated for use in the treatment of surgically created osseous defects or osseous defects created from traumatic injury to the bone.
Vitoss Bone Graft Substitutes are intended for filling bony voids or gaps of the skeletal system (i.e., the extremities, pelvis and posterolateral spine) and may be combines with saline, autogenous blood, and/or bone marrow. Following placement in the bony void or gap, the scaffold resorbs and is replaced with bone during the healing process. The osteostimulatory nature of Vitoss BA and Vitoss BA2X has not been correlated to human clinical experience.
