Collagen PlugsImpregnated with Bone Graft

Boxed in 5 units, 10x20mm sterile plug in each. A simple alternative to your typical allograft and membrane technique to repair a defect, with less to dislodge or wash out than a particulate-and-membrane technique.

  • The SpongeGraft Plug delivers the graft as one preformed plug: no mixing, no packing, no loose particulate.
  • The ideal indication is following an atraumatic extraction when all walls are preserved.

  • In intact, contained sockets, no separate membrane is needed. Place the plug dry and suture over it.

  • An osteoconductive scaffold the patient’s own bone forms along, ahead of implant placement.

Choosing between them

Same plug. Two minerals, and they behave differently.

The mineral inside the collagen is the whole difference. It sets how fast the graft resorbs, and that, in turn, sets how long the ridge keeps its volume.

SpongeGraft · β-TCP + hydroxyapatite. Turns over faster of the two, because the β-TCP fraction is the more soluble of the pair. It is osteoconductive: the patient’s own bone forms along the scaffold rather than being induced by it, and published human histology of β-TCP/HA grafts still finds residual particles at around six months. Generally chosen for routine sockets where a synthetic mineral is preferred.

Clinical rationale

Leave the socket empty and the ridge resorbs, most of it early

After you remove a tooth, the alveolar ridge resorbs predictably. Published research reports that a large share of ridge width and height can be lost in the months following extraction, with most of the change happening early. Wait too long to plan, and what was a routine implant site may need augmentation first.

Grafting the socket when you extract aims to limit that loss and keep enough bone volume for a straightforward implant later. In published work, grafted sites needed extra augmentation at implant placement far less often than sites left untreated.

On timing: Healing time varies with the site and patient. In favorable, contained sockets new bone can mature enough for implant placement in as little as ~3 months, while a more conservative window is around 4–6 months. Always confirm readiness clinically and radiographically before placing an implant.

From the manufacturer

About SpongeGraft

One-step grafting technique for implant preparation

Dr. Miroshnik Vladislav, DMD, Ashdod, Israel

Material and method: vertical and horizontal ridge augmentation using SpongeGraft. Immediate implant placement. 4 months post-op: panoramic + CT.

Central teeth extraction

Dr. Ira Reiz, DMD, Gaithersburg, MD, USA

Central tooth replacement. A light-cured temporary crown material was bonded to adjacent teeth until the site is healed. Layered for higher esthetic. SpongeGraft plug for the post-extraction socket; no membrane used. The site is sutured with PGA sutures.

Open sinus lifting (lateral technique) using SpongeGraft

Dr. Alexey Martynov, Almaty, Kazakhstan

Full video case: three implants installation in the maxillary zone, including lateral sinus lifting. SpongeGraft is used for void filling after the membrane lift. In this video, we cover preparation and the surgery itself.

Lateral ridge augmentation with SpongeGraft, combined with simultaneous implant placement

Dr. Miroshnik Vladislav, DMD, Ashdod, Israel

A case showing another option of using the SpongeGraft, as a bone filler to cover the exposed implant threads, without the membrane. New bone formation around the implants shown at three months.

    I have been using the Sponge plugs as a routine in my extraction site alone or combined with a biomaterial. Handling properties are excellent. I am very much satisfied with the results.

  • Dr. Zagulyaev Alexander in the reception area of his Z-dent clinic

    Dr. Zagulyaev Alexander

    In our clinics, we use mostly compressive implants with an immediate loading technique, “same day teeth”. SpongeGraft is a core part of our clinical protocol for faster and more confident implant loading.

  • Dr. Miroshnik Vladislav in scrubs in his clinic

    Dr. Miroshnik Vladislav

    SpongeGraft is much more than a post-extraction socket solution. With sufficient surgeon’s skill, it becomes a valuable tool, useful in very compromised bone cases.

Before you order

What clinicians ask before ordering

Do I need a separate membrane?

In intact, contained extraction sockets the plug can be placed without a separate membrane as a one-step procedure. Where the socket walls are deficient or the defect is not contained, a membrane is still recommended per standard grafting principles and your clinical judgment.

What if the buccal plate is missing or the socket isn’t contained?

A plug is at its best in a contained socket with intact walls, where the collagen body can form-fit the site and the walls hold the graft. Where the buccal plate is deficient or the defect is not contained, treat it as a guided bone regeneration case: add a barrier membrane, consider supplementing with particulate, and plan flap management accordingly. We would rather tell you that up front than have you use it outside its comfort zone.

How long before I can place an implant?

Healing time depends on the site and the patient. In favorable, contained sockets new bone can mature enough for implant placement in as little as roughly 3 months; a more conservative window is around 4–6 months. Always confirm bone readiness clinically and radiographically before placing the implant.

What is the difference between SpongeGraft and Sponge ZenGraft?

Both are 10 × 20 mm bone graft plugs built on a bovine Type I collagen carrier, placed the same way. The difference is the mineral phase: SpongeGraft (DS-SG1020) uses a synthetic 60% β-tricalcium phosphate / 40% hydroxyapatite blend with a balanced resorption profile, while Sponge ZenGraft (DS-ZG1020) uses a deproteinized bovine bone xenograft that resorbs more slowly, favored when long-term volume maintenance is the priority.

My patient won’t accept animal-derived material, or has alpha-gal syndrome. What are my options?

Patients decline xenograft material far more often than synthetic material, usually for religious, vegan, or personal reasons, so it is worth having both on the shelf. SpongeGraft’s mineral phase is fully synthetic (β-TCP / hydroxyapatite), while Sponge ZenGraft’s mineral is deproteinized bovine bone. Be aware that both products use a bovine Type I collagen carrier, so neither is free of animal-derived material — for a patient with alpha-gal syndrome or a strict objection to any animal tissue, that distinction matters and the conversation should be documented. Ask us and we will send the manufacturer’s composition and instructions for use so you can review the sourcing before you treat.

Can I trim the plug, and is one enough for a molar socket?

The plug is 10 × 20 mm and can be shaped to the socket. For a narrow or shallow site, trim it with sterile scissors or a scalpel to match the root form; for a wide molar socket, use more than one plug so the site is properly filled rather than stretching one plug over a defect it cannot fill. Ask us and we will help you work out a realistic per-case usage from your extraction volume before you commit to a bundle.

Do I need primary closure, or can the site be left to heal by secondary intention?

Socket grafting does not require primary soft tissue closure. Published comparisons of primary closure against secondary marginal healing over a grafted extraction site found no meaningful difference in bone volume at re-entry, and advancing a flap moves the mucogingival junction and adds swelling. Many clinicians place the plug, leave it exposed at the crest, and secure it with a cross-suture. Where you already have a flap up, or the defect is not contained, close as your case dictates.

Can I use it with PRF or PRP?

Yes — combining a collagen plug with PRF or PRP is a well-documented ridge preservation approach and clinicians do it routinely. The plug is supplied ready to place dry, so nothing about the product requires it; follow the instructions for use and your own protocol.

How is each plug supplied?

Each box contains 5 plugs, each individually packaged and sterile in a double blister, with instructions for use included. You place the plug dry, directly from the blister. No rehydration or chairside mixing required.

How do I know the stock is genuine and properly in date?

Everything ships in original, sealed manufacturer packaging from our own inventory in Lakewood, New Jersey — nothing is drop-shipped to you from overseas. Every blister carries its lot number and expiry date, and instructions for use are in every box. If you are ordering a larger bundle and want to be sure the dating suits your case volume, ask before you pay and we will confirm the lot and expiry in writing with your quote.

What code do practices bill this under?

Grafts placed into a fresh extraction site for ridge preservation are generally reported under CDT D7953 (bone replacement graft for ridge preservation), per site. Coverage varies widely between plans and many treat it as elective unless it is tied to a planned implant, so verify benefits and send a narrative with radiographs where the case warrants it. We supply the material — we can’t advise on your billing, and nothing here is a guarantee of reimbursement.

How does ordering work? Is there an online checkout?

No checkout and no account. Pick your product and bundle, send the quote request (or just call or WhatsApp us), and we reply with a written price and lead times. Confirm by email, phone, or WhatsApp and your order ships from Lakewood, NJ. Your details go to our sales team only, and there’s no rep visit unless you ask for one.

What does the free placement tool do?

The double-sided tool (SGTOOL) is an autoclavable instrument with a spatula end to grasp and deliver the graft and a bone-pusher end to condense the plug into the socket. It is purpose-built for placing the Sponge plugs, and one tool (a $59 value) is included free with every bundle purchase.

How fast do orders ship, and where from?

Orders ship from our Lakewood, New Jersey location for fast delivery across the US. Have a question about lead times or a larger order? Call or message us directly and you’ll get a real answer, fast.
