Sterile, sealed boxesCategory comparison
They are not two versions of the same product. A collagen plug, such as HeliPlug or CollaPlug, contains no mineral, is absorbed within days to a few weeks, and is indicated for controlling bleeding and protecting the wound. A bone graft plug carries a mineral scaffold that stays in the site for months and is indicated for grafting. Both are plug-shaped, both go into an extraction socket, and they do different jobs.
The difference
Two products that share a shape and a socket, and share very little else.
| Attribute | Bone graft plug | Collagen plug |
|---|---|---|
| Contains mineral | Yes. A synthetic or bovine mineral held in a collagen carrier | No. Collagen only |
| Time in the site | Months, as a scaffold | 10 to 14 days (HeliPlug) to roughly 2 to 4 weeks (CollaPlug), then absorbed |
| Manufacturer’s stated indication | Extraction socket and ridge preservation grafting | Control bleeding and protect the surface of the wound from further injury |
| Bone-formation claim | Osteoconductive: a scaffold along which the patient’s own bone forms | None made by the manufacturer |
| Typical hemostatic role | The collagen carrier takes up blood as it is placed | Hemostasis in 2 to 5 minutes, which is its primary purpose |
| Examples | OsteoGen, RegenerOss, SpongeGraft, Sponge ZenGraft | HeliPlug, CollaPlug |
Indication wording is quoted from each manufacturer’s own published material. Integra indicates HeliPlug for application to moist or bleeding oral wounds created during dental surgery, to control bleeding and protect the surface of the wound from further injury.
Why the distinction matters
Ridge remodeling after an extraction runs over months, and most of the dimensional change happens in the first three to six. A material absorbed within a few weeks is not present for the period during which a scaffold would do its work. This is not a criticism of the dressing: its manufacturer publishes the absorption window plainly and makes no bone-formation claim on the strength of it.
Covering a socket is better than leaving it open, and a dressing stabilizes the clot, controls bleeding and protects the site while soft tissue closes. Published work on collagen plugs in socket preservation reports them as a simple and inexpensive option. What the literature does not support is treating one as equivalent to a mineral graft where ridge volume is the objective.
A collagen dressing costs a fraction of what a mineral plug costs, which is exactly what invites the substitution. The gap reflects what is in the box: one contains a mineral scaffold and one does not. We cannot put figures on that comparison, because most bone graft plug prices in the US are not published at all.
At least one product sits in the bone grafting aisle, is called a bone filling material, and contains no mineral. Foundation, distributed in the US by J. Morita, is bovine atelo-collagen, and its own manufacturer states that it is not a bone substitute. It also carries the most forward implant-timing claim we found in this category, describing implants placed in some cases as early as eight weeks.
We report that claim because the manufacturer publishes it. We do not adopt it, and no timeline on this site is presented as an outcome to expect. Time to implant placement depends on the site and the patient, and bone readiness needs confirming clinically and radiographically.
None of that is a lesser use. It is the use the product is indicated for, and a dressing chosen for those reasons is the correct product.
Clinical evidence
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
A meta-analysis of ridge preservation against unassisted 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, with implants placed in the planned position without further augmentation at 90.1% of grafted sites against 79.2% of untreated ones. Those trials tested grafting. They are not evidence for what a collagen dressing alone achieves.
Evidence about the material classes
Mineral grafts act as a scaffold along which the patient’s own bone forms, rather than forming bone themselves, and reviews have not established that any one material class is clinically superior for hard-tissue outcomes. Human histology finds residual graft particles persisting at five to six months for both synthetic and bovine mineral, which is part of how a scaffold works rather than a shortcoming. Collagen alone offers no mineral phase to persist.
Evidence about these specific products
We are not aware of published randomized controlled trials establishing outcomes for most of the individual plugs named on this page, ours included. The distinction this page draws does not rest on trial data: it rests on what each manufacturer states its product contains and what it is indicated for, which is published and checkable.
Evidence for grafting a socket is not evidence for covering one, and neither is evidence for a named product. The tiers above are kept apart for that reason.

Every value on this page was read from the source listed against it on that date, and confirming current specifications against the instructions for use in the box remains the clinician's call.

Common questions
No. A collagen plug such as HeliPlug contains no mineral and no bone-derived material. Its manufacturer indicates it for controlling bleeding and protecting the wound surface, and makes no bone-formation claim. A bone graft plug carries a mineral scaffold and is indicated for grafting.
They are indicated for different things. A collagen dressing covers and protects the site and is absorbed in 10 to 14 days; ridge remodeling continues for months after that. Where maintaining ridge volume for a planned implant is the objective, a dressing is not a substitute for a graft. Where hemostasis and wound protection are the objective, it is the right product.
CollaPlug is a collagen wound dressing in the same category as HeliPlug: collagen only, absorbed within roughly two to four weeks, indicated for bleeding control and wound protection. The FDA device registry lists both under Integra LifeSciences. A bone graft plug contains a mineral phase held in a collagen carrier and stays in the site for months as an osteoconductive scaffold.
Because of what is in it. A collagen dressing is collagen; a graft plug also contains a synthetic or bovine mineral. We cannot give you the two prices side by side, because most US bone graft plug pricing is only shown to signed-in trade accounts.
Yes. Foundation, distributed in the US by J. Morita, is sold as a bone filling material and sits in the bone grafting aisle, and it is bovine atelo-collagen with no mineral component. The manufacturer states that it is not a bone substitute. Checking the composition rather than the shelf is the reliable way to tell.
