Sp-Block

Tissue of origin   Equine cancellous block
Tissue collagen   Preserved
Physical form   Rigid dried block
Composition   100% cancellous bone
Re-Entry Time   Variable depending on characteristics and irroration grade of grafting site and on clinical conditions of patient - about 8 months
Packaging   Collagenated Block: 10x10x20mm

 

Characteristics: cancellous block of equine bone produced with an exclusive Tecnoss process which avoids ceramization of the hydroxyapatite crystals, thus accelerating physiological resorption. Sp-Block supports new bone formation: thanks to its rigid consistency it is able to maintain in time the original graft volume, which is particularly important in case of large regenerations. Moreover, its collagen content facilitates blood clotting and the subsequent invasion of regenerative and repairing cells, favoringrestitutio ad integrum of missing bone. 

The block's complete biocompatibility and bioavailability have been demonstrated by tests conducted at the Università degli Studi di Torino, according to the ISO 10993 method. Because of their marked "hygroscopicity", they can function as carriers of selected medication and drugs.


Handling: Sp-Block must be hydrated before use for 5/10 minutes with sterile lukewarm physiological solution or with antibiotics. Afterwards, it can be adapted to the receiving site which must be accurately decorticated in order to guarantee maximum contact; the block must always be fixed with osteosynthesis microscrews and should be protected with a resorbable barrier (Evolution membrane).
 

CLINICAL INDICATIONS SUMMARY

Dental and Oral Surgery: horizontal bone augmentation of wide volume requiring grafts with good scaffold properties.

Maxillofacial Surgery: partial or total reconstruction of destroyed anatomical parts due to traumas and tumors. 
 


CLINICAL INDICATIONS OVERVIEW


A bone graft is a material used to repair a bone defect or deficiency contour and/or volume. The use of these materials in regenerative procedures is based on the assumption that they are osteoconductive i.e. serve as scaffold for new bone formation.

The entire OsteoBiol line consists of xenografts, i.e. biomaterials deriving from heterologous bone and soft tissues. The Tecnoss patented manufacturing process used to obtain these materials is able to achieve biocompatibility preserving part of the collagen matrix of the animal bone and avoiding at the same time high temperatures that would cause ceramization of the bony tissue: the result is a unique biomaterial, consisting of mineral component and organic matrix, with a porous surface extremely similar to autogenous bone and able to resorb progressively while new bone formation takes place.
