Sterile, sealed boxesProduct record
A collagenated bone substitute block, not a plug: 90% deproteinized bovine bone mineral granules bound by 10% porcine collagen, cut to fit and placed dry or moistened. Two species in one product, which matters wherever a patient restricts animal-derived material. It is the most independently studied product in our database, and its manufacturer is the one voice in the category stating plainly that the collagen does not replace a membrane.
Specifications
Composition is quoted verbatim from Geistlich. Note the two species: the mineral is bovine and the collagen is porcine, and at least one US distributor listing found during research labels the product porcine outright, describing the 10% and ignoring the 90%.
Against the rest of the category
Differences of fact, taken from the published record. None is a claim that this product performs better or worse than any other.
The mineral is bovine; the collagen binder is porcine. Every other collagenated product in our database uses bovine collagen. For a patient with a religious or dietary restriction this is the deciding fact, and bovine and porcine restrictions are not the same restriction, so neither half of the composition can stand in for the whole.
Geistlich states: the collagen is absorbed after a few weeks and does not replace the barrier function of a membrane. Several plug vendors state or imply the opposite about their own collagen. That written disagreement between manufacturers is the single sharpest fact in this category, and Geistlich’s is the restrained side of it.
Deproteinized bovine bone mineral is the most studied graft material class in dentistry, and Bio-Oss specifically appears across decades of independent trials and histology. No other product in our database approaches it. That is a fact about evidence depth, not a superiority finding: reviews still do not establish any material class as clinically superior for hard-tissue outcomes.
In the manufacturer's words
Quoted rather than paraphrased, so the claim can be checked against its source.
The collagen is absorbed after a few weeks and does not replace the barrier function of a membrane.
Geistlich, Bio-Oss Collagen product documentation
Our note Quoted because it is the most restrained membrane statement any manufacturer in this category makes, and it contradicts the blanket no-membrane marketing common among plugs. Our own position is conditional in the same direction: only an intact, contained socket supports one-step placement without a separate membrane.
Low resorption rate, enabling long-term volume stability.
Geistlich, Bio-Oss Collagen product documentation
Our note Consistent with independent histology: bovine mineral particles are reported as not resorbed but surrounded by new bone at six months. Slow resorption is a designed property here, favored where long-term volume maintenance is the priority, and it also means residual particles persist rather than the graft being fully replaced.
Both quotes are Geistlich's. We reproduce them because they are unusually restrained for this category, and restraint is worth showing; reproducing them is not an endorsement of any 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 comparing ridge preservation with 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 as planned without further augmentation at 90.1% of grafted sites against 79.2% of untreated ones.
Evidence about the material class
Human histology of ridge preservation with deproteinized bovine bone mineral reports the particles as not resorbed but surrounded by new bone, at 19.0 ± 6.5% of tissue at six months. The mineral acts as an osteoconductive scaffold and a long-term space maintainer rather than being replaced. Reviews have not established this class, or any class, as clinically superior for hard-tissue outcomes.
Evidence about this specific product
Bio-Oss and Bio-Oss Collagen appear in independent peer-reviewed trials and histological studies across ridge preservation and guided bone regeneration, including the histology cited above. This is the exception in our database: for most plugs, product-level evidence is manufacturer documentation only. We have not compiled a systematic ledger of the Bio-Oss literature and do not summarize outcomes we have not reviewed.
Evidence about the procedure and about a material class is not evidence about a product, and this page keeps them apart even for the one product in the category where the third tier is genuinely populated.
State of the record
Comparable products
Grouped by what each one shares with the product above, not by preference.
MinerOss X Collagen
The nearest like-for-like: a collagenated block of anorganic bovine bone, published as 95% mineral and 5% bovine collagen. Its collagen is bovine where Bio-Oss Collagen’s is porcine.
MinerOss X Plug
Bovine mineral in plug form: 80% bovine cancellous particulate, 20% bovine collagen, in socket-shaped sizes rather than a cut-to-fit block.

The bovine-mineral option in our own range: deproteinized bovine bone mineral on a bovine Type I collagen carrier, in a 10 × 20 mm plug, five per box, price published. Single species throughout.
The synthetic-mineral contrast in plug form: 80% carbonate apatite, 20% bovine collagen, faster published resorption than bovine mineral.
A synthetic non-ceramic calcium apatite plug; radiolucent at placement, with a chemistry its manufacturer distinguishes from every other product here.
Listed because each shares something specific with the product on this page, not because any of them is better. Published reviews have not established that any material class is clinically superior for hard-tissue outcomes. One of these is ours and is marked.
Last verified 2026-08-21. Manufacturers change formulations, packaging and published claims without notice. 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
Geistlich publishes it as 90% Geistlich Bio-Oss granules, a deproteinized bovine bone mineral, and 10% porcine collagen. The mineral is bovine and the collagen is porcine: two species in one product.
Both. The 90% mineral fraction is bovine bone; the 10% collagen binder is porcine. Listings that call it simply porcine are describing the binder and ignoring the mineral. For any patient with a species restriction, both halves need checking.
No. It is a collagenated block sold by mass in four sizes, cut to fit the defect. Plugs come pre-shaped to socket dimensions; this does not, and price-per-unit comparisons against plugs are invalid without a stated normalization basis.
Geistlich states that the collagen is absorbed after a few weeks and does not replace the barrier function of a membrane. That is the most restrained membrane statement in the category, and several plug manufacturers claim the opposite about their own collagen. Whether a given case needs a barrier depends on containment, and that is the clinician’s call.
Slowly, by design. Geistlich describes a low resorption rate with long-term volume stability, and independent histology reports the mineral particles as not resorbed but surrounded by new bone at six months. It is favored where long-term volume maintenance is the priority, not where fast turnover is wanted.
