SpongeGraft vs. ZenGraft: choosing the right bone graft solution for optimal outcomes

SpongeGraft vs. ZenGraft: choosing the rightbone graft solution for optimal outcomes

In the field of oral surgery and implantology, effective wound management and bone regeneration are paramount for successful treatment. Dental professionals rely on a variety of advanced biomaterials to achieve optimal healing and create a stable foundation for implants. DSI Dental Solutions offers an extensive range of biomaterials, including absorbable sponges and bone grafts. Among these, DSI SpongeGraft and DSI ZenGraft stand out as innovative bone-impregnated collagen plugs designed for post-extraction site regeneration and various bone defect repairs. Both respond to the need for effective, predictable, and minimally invasive grafting techniques, especially where traditional allograft, membrane, or particulate approaches present risks like washout or membrane dislodgement. These products simplify bone regeneration following tooth extraction, periodontal surgery, or implant placement by combining graft stability, biological cues, and ease of handling. This blog highlights their compositions, applications, and key differences to help clinicians make informed decisions.

The Need for Bone Grafting Products

Tooth extraction and oral surgeries typically result in residual bony voids. These defects, if untreated, may lead to ridge atrophy, impaired healing, poor implant stability, and compromised aesthetics. Conventional methods - such as particulate grafts covered with resorbable membranes - often risk material displacement, incomplete integration, or require multiple procedural steps. Modern biomaterials like DSI SpongeGraft and ZenGraft have emerged to simplify the process, minimize infection risk, eliminate the need for membranes, and optimize both biological and procedural outcomes.

General Overview of DSI SpongeGraft andDSI Sponge ZenGraft
DSI SpongeGraft is a plug composed of two-phase composition of bovine tendon collagen type I and a calcium phosphate/hydroxyapatite formula. Its design closely mimics natural bone, offering biological cues for healing and structural stability for new bone growth. The mineral component resorbs slowly, supporting long-term regeneration. It readily adapts to extraction sockets and defects without pre-rehydration or risk of particulate washout, forms its own membrane, and delivers rapid healing suitable for early or delayed implant placement (12-14 weeks).

Key features:‍

• Cost-effective, single-step application in intact sockets
• Self-sealing and volume-maintaining: prevents tissue collapse and graft washout
• Expedited wound healing and cell migration containment
• Simple adaptation, easy to trim/shape for custom fit
• No membrane required: forms own protective layer
• Suitable indications: ridge preservation, periodontal defects, maxillofacial procedures, sinus augmentation, post-implant healing

Product Overview: DSI ZenGraft
DSI ZenGraft is a two-phase composition of bovine tendon collagen type I, impregnated with deproteinized bovine xenograft. The xenograft particles promote revascularization, stabilize blood clot formation, and areoptimized for bone conduction and integration. This product is especially valuable in more complex cases - such as sockets with compromised walls - byenhancing particle adhesion and osseoconductivity. It possesses both osteoinductive and osteoconductive properties, contributing to robust bone regeneration.

Key features:

• Ideal for complex defects, including those with missing socket walls
• Superb physical characteristics for repair of various bone defects
• Promotes predictable,  strong healing and long-term volume stability
• Stabilizes clots and encourages revascularization through xenograft composition
• No membrane required; slow absorption allows optimal bone conduction
• Convenient handling and easy placement
• Suitable indications: generalized maxillofacial and periodontal surgery, defects around implants, post-resection, cystectomy, crest/hole preservation

Differentiating Features
While both products are excellent for bone regeneration, their core compositions and specific benefits lead to distinct optimal uses. The key difference lies in the type of bone graft material used to impregnate the collagen matrix.
SpongeGraft combines pure bovine collagen with a synthetic bone substitute (calcium phosphate/hydroxyapatite). This composition aims to mimic natural bone while providing a predictable scaffold for new bone formation and excellent volume stability. It is effective for maintaining the volume of the extraction socket and supporting early healing, which is crucial for subsequent implant placement or aesthetic outcomes.
ZenGraft, on the other hand, integrates bovine tendon collagen type I with deproteinized bovine xenograft. Xenografts are natural bone substitutes derived from animal sources, which are typically processed to remove organic components, making them biocompatible but retaining their natural bone structure. This xenograft component provides osteoinductive and osteoconductive properties, meaning it can actively stimulate the formation of new bone and serve as a scaffold for bone growth. This natural origin component often contributes to a potentially faster healing process in a wider array of bone defects.

Below is a side-by-side comparison of theirkey characteristics:

Clinical Applications: Selecting theRight Material
Understandingthe unique characteristics of each product allows clinicians to select the mostappropriate solution for specific patient needs. Contemporary literatureconsistently demonstrates that deproteinized bovine grafts (a key component in ZenGraft)offer strong biocompatibility and bone integration, with less inflammation andimproved new bone formation compared to older graft types. Meanwhile,plug-style solutions like SpongeGraft help avoid dimensional lossassociated with extraction and deliver new bone faster for early implantation. Tochoose effectively, dental professionals should assess the type and size of thebone defect, the required healing time, and the need for active boneregeneration stimulation.

• Choose SpongeGraft for  routine socket preservation, minimal trauma cases, and situations where socket walls remain intact. It excels in eliminating washout and delivering quick, predictable healing suitable for expedited implant placement. Its ability to maintain socket volume and prevent tissue collapse is highly beneficial for preserving the alveolar ridge and improving long-term aesthetic outcomes.
• Choose ZenGraft for more demanding cases - such as defects with missing walls (especially buccal), after cystectomy or resection, or when enhanced osseoconduction and graft particle adhesion are needed. Its collagen-xenograft blend supports stable integration and bone regeneration even in challenging conditions. Also - its natural xenograft component contributes to active new bone formation providing slightly slower healing period. In the procedures such as Open Sinus Lifting (Lateral technique) the osteoinductive and osteoconductive properties of ZenGraft can be particularly advantageous.

Compared with classical procedures, both products outperform conventional approaches by removing the need for additional coverage membranes, slashing procedure time and reducing risks of membrane displacement or incomplete healing. This makes them ideal for guided bone regeneration (GBR) and other procedures where containment and biological compatibility are critical, where they can act as a bone filler even without a barrier membrane, as demonstrated in clinical cases.

Convenienceand Outcome Optimizatio

• Easy trimming and placement: Both products are easily shaped to fit defects, reducing chair time and simplifying procedures
• Volume maintenance: Prevents tissue collapse and ensures preservation of ridge for aesthetic restoratio
• Sterile, cost-effective, and predictable: Available in individual blisters, each plug provides a reliable, reproducible outcome for clinicians.
• Both suitgeneral maxillofacial and periodontal procedures, minimize infection risk,enable faster healing, and result in improved long-term restorative outcomes.

Conclusion
DSI SpongeGraft and ZenGraft set a new benchmark for bone grafting in dental and maxillofacial surgery. Their innovative compositions eliminate membrane dependence and particulate washout while providing stable integration, easy handling, and clinically predictable healing -whether the case is routine or complex. Choosing the right product depends on socket and defect morphology, with SpongeGraft excelling in intact sockets and ZenGraft optimizing outcomes in multifaceted or compromised sites. Both deliver lasting support for implants, aesthetics, and oral health restoration. By carefully considering the specific clinical scenario and desired patient outcomes, dental professionals can leverage the strengths of each product to achieve superior results in bone regeneration – so both products are “must – have” in the arsenal of all professional implantologists.
