What is a bone graft plug and how does it work?

A bone graft plug is a pre-formed collagen-based insert impregnated with bone graft material, placed dry directly into an extraction socket after tooth removal. It simultaneously achieves hemostasis, stabilizes the blood clot, and provides an osteoconductive scaffold for new bone formation — all in a single step, without the need for a separate membrane or particulate graft mixing. DSI bone graft plugs are form-fitted to the socket, eliminating graft washout and membrane dislodgement risks.

What is the difference between DSI SpongeGraft and Sponge ZenGraft?

SpongeGraft combines bovine collagen with synthetic calcium phosphate/hydroxyapatite (TCP/HA), closely mimicking natural bone composition. It offers slow, controlled resorption and is ideal for atraumatic extractions with all socket walls intact — site ready for implant in 12–14 weeks. ZenGraft combines bovine tendon collagen type I with deproteinized bovine xenograft (Zenoss), delivering faster revascularization and pronounced osteoconductive results. ZenGraft is preferred for cases with compromised socket walls, larger defects, or when faster biological healing is a priority.

Do I need a membrane when using bone graft plugs?

No. Both SpongeGraft and ZenGraft are specifically engineered to form their own biological barrier, eliminating the need for a separate collagen membrane in most cases. The collagen envelope acts as a natural membrane, limiting cell migration and accelerating healing. A separate membrane may still be recommended in cases with severely compromised socket walls or large defects requiring additional GBR support.

How long until the implant can be placed after using a bone graft plug?

With DSI SpongeGraft, the extraction site is typically ready for implant placement within 12–14 weeks. The collagen component resorbs within 4–6 weeks, while the TCP/HA mineral phase resorbs gradually over 3–6 months, providing continuous scaffolding for new bone formation throughout the healing phase. ZenGraft, with its bovine xenograft component, may offer a shorter healing window in appropriate clinical cases.

What clinical cases are bone graft plugs indicated for?

SpongeGraft and ZenGraft are indicated for: post-extraction socket preservation, alveolar ridge preservation, periodontal defects, peri-implant defects, sinus augmentation, guided bone regeneration (GBR) procedures, defects after resection or cystectomy, and wound healing post-implant surgery. SpongeGraft is ideally suited for intact 4-wall sockets following atraumatic extraction. ZenGraft is preferred for more complex defects or cases requiring faster revascularization.

Bone Graft Plugs — One-Step Socket Preservation. No Membrane Required.

Forget the complexity of traditional bone grafting. DSI bone graft plugs deliver a complete socket preservation solution in a single step — no pre-rehydration, no membrane, no mixing of particulate material. Simply place dry into the extraction socket and suture.

DIP Dental carries two complementary DSI bone graft plug formulations:

SpongeGraft — A dual-phase plug combining pure bovine collagen (Achilles tendon matrix) with synthetic calcium phosphate/hydroxyapatite (TCP/HA). The collagen phase stabilizes the clot and delivers blood flow for early angiogenesis. The mineral phase provides primary stability and slow, controlled resorption - closely mimicking the organic and inorganic composition of natural bone. No graft washout. No membrane dislodgement. Site ready for implant placement in 12–14 weeks. Ideal indication: atraumatic extraction with all socket walls intact.

Sponge ZenGraft — A fully bovine two-phase plug combining bovine tendon collagen type I with deproteinized bovine xenograft (Zenoss). The xenograft component promotes faster revascularization and delivers pronounced osteoconductive results. Superior handling for cases with compromised socket walls, periodontal defects, peri-implant defects, and cystectomy sites. Shorter healing time compared to synthetic alternatives.

Clinical indications for both: Post-extraction socket preservation · Ridge preservation · Periodontal defects · Peri-implant defects · Sinus augmentation · GBR procedures · Defects after resection or cystectomy

FDA, CE & ISO compliant. Sterile, individually packed.
