Bone Grafts & Membranes

Bone Grafts & Membranes for GBR, Sinus Lift, Ridge Preservation and Periodontal Defect Repair

Bone grafts and barrier membranes are the guided bone regeneration (GBR) and guided tissue regeneration (GTR) materials used to rebuild alveolar bone lost to extraction, periodontal disease, infection or implant dehiscence — restoring volume and contour for predictable implant placement, ridge preservation or periodontal repair. Dentalkart stocks xenograft and alloplast bone graft particulate plus bio-resorbable collagen membranes from Geistlich, NovaBone and XCEM.

Types of Bone Graft & Membrane

Xenograft bone substitute (deproteinised bovine)

Deproteinised bovine cancellous granules that retain native trabecular architecture for predictable osteoconduction in extraction sockets, sinus lifts and ridge augmentation — the gold standard slow-remodelling graft, for example, Geistlich Bio-Oss Collagen Spongious Bone Substitute.

Bioactive glass alloplast (Perioglas)

Synthetic calcium phosphosilicate (Bioactive Glass) particulate that bonds chemically to bone and releases ions which stimulate osteogenesis — ideal for periodontal intrabony defects and contained ridge defects. For example, NovaBone Perioglas 6 x 0.5cc.

Porous alloplast granules

Porous synthetic granules with macro and micro-porosity that promote vascular ingrowth and progressive resorption-replacement with native bone — ideal for ridge preservation and contained defects, for example, NovaBone Porous Granules 1 x 0.5cc 0.25gm.

Bio-resorbable collagen GBR membrane

Type-I bovine collagen barrier membrane that excludes soft-tissue ingrowth and protects the graft during the 4–6 month healing window — resorbs naturally without second surgery, for example, XCEM Osspore Collagen Membranes.

When Bone Grafts & Membranes Are Used

• Socket preservation immediately after tooth extraction
• Guided bone regeneration (GBR) around implants with dehiscence or fenestration defects
• Lateral and crestal sinus floor elevation for posterior maxillary implants
• Periodontal intrabony and furcation defect regeneration (GTR)
• Ridge augmentation before staged implant placement
• Cyst-cavity and apicectomy site fill
• Horizontal and vertical ridge augmentation

How to Choose the Right Bone Graft & Membrane

1. Match graft type to defect: xenograft (Geistlich Bio-Oss) for slow remodelling + volume stability; alloplast (NovaBone Perioglas, Porous Granules) for full resorption-replacement in contained defects.
2. Pick particle size by site — 0.25–1.0 mm for extraction sockets and GBR; 1.0–2.0 mm for sinus lift cavities.
3. Use a bio-resorbable collagen membrane (XCEM Osspore) wherever soft-tissue exclusion is required — typically all GBR cases and lateral-window sinus lifts.
4. For periodontal intrabony defects, bioactive glass (Perioglas) outperforms passive xenografts because of ion-stimulated osteogenesis.
5. Hydrate the graft with sterile saline or patient blood before placement; pack with light pressure to avoid crushing the granules.
6. Verify CE/FDA/CDSCO marking, lot and expiry on every sterile vial — graft material has a 24–36 month shelf life.

What are bone grafts and membranes used for?

Bone grafts and membranes are used together to rebuild alveolar bone lost to extraction, periodontal disease, infection or implant dehiscence. The graft provides the osteoconductive scaffold for new bone formation, and the barrier membrane excludes soft-tissue ingrowth during the 4–6 month healing window — together restoring volume and contour for predictable implant placement or periodontal repair.

What is the difference between xenograft and alloplast bone graft?

The difference between xenograft and alloplast bone graft is origin and remodelling behaviour. Xenografts (Geistlich Bio-Oss) are deproteinised bovine bone — slow-remodelling, hold ridge volume long-term, ideal for delayed implant placement. Alloplasts (NovaBone Perioglas bioactive glass) are synthetic — resorb fully as new native bone replaces them, ideal for contained defects.

Do I need a membrane every time I place a bone graft?

You need a membrane every time the graft site has a soft-tissue boundary that could collapse into the defect — most GBR, sinus lift lateral windows, and ridge augmentation cases. For contained four-wall extraction sockets the graft is often stable without a membrane, but for dehiscence and fenestration around implants a resorbable collagen membrane (XCEM Osspore) is essential.

How long do collagen GBR membranes take to resorb?

Collagen GBR membranes typically resorb in 4 to 24 weeks depending on cross-linking. Native non-cross-linked Type-I collagen breaks down in 4–8 weeks. Cross-linked or layered membranes like XCEM Osspore last 16–24 weeks — long enough to cover the early osteogenesis phase before resorbing naturally without a second surgery to remove them.

Are the bone grafts and membranes on Dentalkart genuine and CDSCO-compliant?

Yes, every bone graft and membrane on Dentalkart is genuine and CDSCO-compliant. All Geistlich, NovaBone and XCEM products are sourced direct from the manufacturer or authorised Indian distributor and ship in sealed sterile primary packaging with the original lot number and expiry date printed for every surgical SKU.
