Demineralized Sponge Strip

Last Updated May 14, 2020
Demineralized Sponge Strip

The demineralized spongy strip or spongy bone is a unique flexible graft manufactured by demineralizing cancellous bone.

  • Compresses temporarily for easy placement
  • Springs back to maintain space
  • Collagen-like porous structure, allows for excellent stem cell matrix and vascularization
Starting at: $149.00

Additional Information for Demineralized Sponge Strip

What is a Demineralized Sponge Strip?

Demineralized Spongy bone is manufactured via a unique acid extraction process of allograft cancellous bone, which results in a loss of the majority of the mineralized components, but with retention of collagen and the noncollagenous proteins, including growth factors. The proprietary demineralization process revolutionizes the handling properties of bone while maintaining natural growth factors. The result is a unique graft material derived from trabecular (cancellous) bone that has compressible and has elastic, sponge-like properties. The DBM allograft that is created has the open, porous structure of cancellous bone while also being compressible and elastic, with the properties of a sponge. It can be compressed to 1/3 of its original size in order to fit a space. It then springs back to fill the void without losing its original strength or shape. The Sponge Strip is therefore a perfect solution for wide variety of grafting situations faced in implant dentistry.

What are the Benefits for Demineralized Sponge Strip in Dental Grafting?

Specifically, the Demineralized Sponge Strip holds space like a block, but because of its structure, it will not perforate a flap. So in certain cases, you may find that instead of making a large vertical incision you can perform a minimal flap instead. The sponge strip is flexible and you can easily insert it even in a minimal. For a complete discussion of this you can see this video: [Implant Grafting Techniques: Demineralized Sponge Strip and Tunneling](

In addition, to working with the strip in the above scenario, the sponge strip is an excellent choice for grafting when performing the tunneling technique. You can even use it without a membrane, as the periosteum acts as a membrane.

Finally, since the sponge strip will not “migrate” or disperse, you can use it in spaces where particulate will be difficult to contain. Instead, you can place the sponge strip there.

Please note, that if you are using the sponge strip in a open flap technique, you will want to add particulate around the strip, so you have a fully grafted area (see link to video above).
