Why a plug
What the plug format actually changes chairside
Six things that are true of both products, and that particulate-plus-membrane grafting does not give you.
One-step handling
Open the sterile blister and place the plug dry into the bleeding socket. No rehydration, no chairside mixing, no particulate to pack.
Form-fits the socket
The Type I collagen body adapts to the socket walls and holds the mineral in place through irrigation and closure, so the graft stays where you put it.
Absorbs blood, stabilizes the clot
Collagen takes up blood on contact and stabilizes the clot as you place, so haemostasis and grafting happen in the same step.
Two mineral options
Choose a synthetic β-TCP / hydroxyapatite mineral or a deproteinized bovine xenograft — same plug format, same placement, different resorption profile.
Sterile, individually packed
Each of the 5 plugs in a box is sealed in its own sterile double blister, with instructions for use included in every box.
Practice bundles with a tool
Buy in bundles and every order includes a free double-sided bone graft tool — a $59 instrument built for these plugs.
The procedure
What is socket preservation?
Socket preservation — also called ridge preservation or socket grafting — is the placement of a graft material into an extraction socket at the time of extraction, to limit the ridge remodelling that follows. It is a procedure, not a product: the clinical technique is yours, and the graft material is the part you choose and buy.
01Why the ridge is worth preserving
Alveolar bone resorbs predictably once a tooth is removed, and most of the change happens early. A systematic review of human studies reported roughly 3.8 mm of horizontal width loss and about 1.2 mm of mid-buccal height loss six months after extraction, with the fastest reduction in the first three to six months. Left unmanaged, a routine implant site can turn into an augmentation case.
02Why the material choice matters
Graft materials differ mainly in how quickly the mineral resorbs. A faster-resorbing synthetic phase turns over sooner as the patient’s own bone forms along it; a slow-resorbing xenograft persists longer as a space maintainer, which is generally favoured when long-term volume stability is the priority. Handling matters too — a carrier that holds the mineral in the socket removes the washout and packing problems of loose particulate.
03Where a plug fits — and where it does not
The ideal indication is an atraumatic extraction where the socket walls are intact and the defect is contained. In intact, contained sockets these plugs are placed as a one-step procedure without a separate membrane. Where a wall is deficient or the defect is not contained, a barrier membrane and standard guided bone regeneration principles still apply — this product does not replace that judgement.

Synthetic vs bovine
Compare the two socket preservation graft materials
Same plug, same placement, same box count. The mineral inside the collagen is the whole difference — and it decides how quickly the graft turns over.

Get practice pricingChairside workflow
Where the plug fits in the extraction visit
Four steps, in the order they happen. The clinical technique is yours — this is only where the material goes.
- 1
Extract and prepare the socket
Extract as atraumatically as the case allows, then debride and curette the socket to your normal protocol. Assess whether the walls are intact and the defect is contained before you choose the graft.
- 2
Select the graft plug
Pick the synthetic or bovine mineral for the case, and the plug count for the site. Plugs are supplied at 10 × 20 mm; sizing and trimming decisions are yours and should follow the instructions for use.
- 3
Place dry, per the IFU
Open the sterile blister and deliver the plug dry into the bleeding socket. No rehydration or chairside mixing. The included placement tool has a spatula end to deliver the plug and a bone-pusher end to seat it.
- 4
Close the site
Complete closure and suturing according to the case. In intact, contained sockets no separate membrane is needed; where walls are deficient, use a membrane and standard grafting principles as you would otherwise.
This is an overview of where the product fits in the visit, not a surgical protocol. Instructions for use are included in every box and govern handling, indications and contraindications.
Clinical-use considerations
Where these plugs fit — and where they don’t
The limits matter as much as the indications. Read this before you order.
- Intended user
- Supplied to licensed dental professionals and dental practices for use in a clinical setting. Nothing on this page is patient advice or a substitute for your own clinical judgement.
- Best-fit indication
- An extraction socket with intact walls, where the defect is contained. The manufacturer names atraumatic extraction with all walls preserved as the ideal indication.
- When a membrane still applies
- A deficient buccal wall or a non-contained defect is a different case. Use a barrier membrane and standard guided bone regeneration principles — the one-step, no-membrane description applies only to intact, contained sockets.
- Both options contain bovine collagen
- The “synthetic” option refers to the mineral phase only: both plugs use a bovine tendon Type I collagen carrier. Neither product is free of animal-derived material, which matters where a patient declines it.
- Healing time varies
- Time to implant placement depends on the site and the patient. Confirm bone readiness clinically and radiographically before placing — no timeline should be assumed from a product page.
- Billing is yours to determine
- Coding and reimbursement for socket preservation are decided by the payer and the case. We supply the material; we make no representation about coverage or payment.
Professional use. For use by licensed dental professionals only. This page is product information for a dental practice audience, not medical or clinical advice, and not a substitute for the manufacturer’s instructions for use — which are included in every box and take precedence. Always apply your own clinical judgement.

Every purchased box is billed at the $219 list price; the free boxes and tool are what the bundle adds, so the “effective per box” figure above is total paid divided by total boxes received, not a discount. Prices exclude any applicable tax. Need a different quantity, or a mix of both materials? Ask and we’ll quote it.
Included with every bundle
The placement tool, and why it’s in the box
Double-sided autoclavable instrument: a spatula end (Ø5.8 mm) to grasp and deliver graft material, and a bone-pusher end (Ø5.0 mm) to condense the plug into the socket. Purpose-built for placing the Sponge plugs. One tool — reference SGTOOL, listed at $59 — is included free with every practice bundle, whichever graft material you choose.
- Spatula end (Ø5.8 mm) grasps and places the plug
- Bone-pusher end (Ø5.0 mm) condenses it into the socket
- Stainless head you autoclave and reuse, no disposables
- Made for the Sponge plugs, so you don’t improvise with a flat instrument
Clinical evidence
What the evidence supports, at three different levels
Evidence for the procedure is not evidence for a material class, and neither is evidence for a specific product. These are kept apart on purpose.
Evidence about the procedure
Grafting the socket reduces ridge loss — but does not stop it
A meta-analysis comparing ridge preservation with unassisted socket healing reported roughly 1.3–1.5 mm less bucco-oral width loss and 0.9–1.1 mm less height loss in grafted sites. In the same analysis, implants could be placed in the planned position without further augmentation at 90.1% of grafted sites, against 79.2% of untreated ones. A European Federation of Periodontology workshop consensus put the preventable reduction at roughly 1.5–2.4 mm horizontally and 1–2.5 mm at the mid-buccal. Resorption is reduced, not eliminated.
Evidence about the material classes
Both mineral classes are osteoconductive — they differ in turnover
β-tricalcium phosphate / hydroxyapatite blends and deproteinized bovine bone mineral are both osteoconductive: they act as a scaffold along which the patient’s own bone forms, rather than forming bone themselves. The practical difference is resorption rate — the β-TCP fraction is the more soluble of the synthetic pair, while deproteinized bovine mineral resorbs slowly and residual particles persist as space maintainers. Reviews of socket-sealing and grafting materials have not established that any one material class is clinically superior for hard-tissue outcomes, so the choice is a case-by-case judgement, not a ranking.

Evidence about these specific products
What exists for SpongeGraft and Sponge ZenGraft, stated plainly
We are not aware of published randomized controlled trials on these two DSI plugs specifically. What does exist is manufacturer-published clinical case documentation and evaluations from clinicians who use them — useful for seeing handling and technique, but not the same class of evidence as the studies above. We would rather say that than let general socket-preservation data stand in for a product claim.
Figures above describe published results for socket preservation as a procedure and for material classes in general. They are not outcome claims for 5-plug DSI SpongeGraft or Sponge ZenGraft boxes, and no clinical outcome is guaranteed.

Before you order
Socket preservation graft questions, answered
What is a socket preservation bone graft?
A socket preservation bone graft is a graft material placed into an extraction socket at the time of extraction to limit the ridge remodelling that follows. Implanex supplies it in plug form: a Type I collagen sponge carrying a bone mineral, shaped to sit in the socket. The plug is the material — the socket preservation procedure itself is the clinician’s.
What is the difference between the synthetic and bovine graft plugs?
Only the mineral inside the collagen. SpongeGraft (DS-SG1020) carries a synthetic 60% β-tricalcium phosphate / 40% hydroxyapatite mineral with a balanced resorption profile. Sponge ZenGraft (DS-ZG1020) carries deproteinized bovine bone mineral, which resorbs slowly and is favoured when long-term ridge volume maintenance is the priority. Both use the same bovine Type I collagen carrier, the same 10 × 20 mm plug and the same placement.
How many graft plugs come in a box?
5 plugs per box, each individually sealed in its own sterile double blister, with instructions for use included. That applies to both the synthetic and the bovine product.
Does the product require mixing or rehydration?
No. The plug is placed dry, straight from the blister, into the bleeding socket. There is no chairside mixing, no rehydration step and no loose particulate to pack.
Is a membrane always required?
In an intact, contained extraction socket the plug can be placed as a one-step procedure without a separate membrane. Where a socket wall is deficient or the defect is not contained, a barrier membrane and standard guided bone regeneration principles still apply. Treat “no membrane” as a description of the contained-socket case, not a general rule.
What plug size is available?
Both products are supplied as 10 × 20 mm plugs. Sizing for a given socket, including whether to trim or use more than one plug, is a clinical decision and should follow the instructions for use.
How quickly are orders shipped, and from where?
Orders ship next day from our Lakewood, New Jersey location, for delivery across the United States. If you need a specific lead time or a larger quantity, call or message us and you will get a direct answer.
How do the practice bundles work?
Bundles are priced on the number of paid boxes. Buy 5 and you also receive 1 free box and 1 free placement tool; buy 9 and you receive 2 free boxes and a tool; buy 13 and you receive 3 free boxes and a tool. Every purchased box is billed at list price — the bundle value is in the free boxes and the tool, not a per-box discount. Bundle pricing starts at 5 paid boxes; ask us if you need a different quantity.
Are placement tools included?
Yes — one double-sided bone graft tool (SGTOOL), a $59 instrument, is included free with every bundle. It is double-ended and autoclavable: a spatula end to grasp and deliver the plug, and a bone-pusher end to condense it into the socket.
