Bone Graft Materials in Oral Surgery and Implant Dentistry

Why Bone Volume, Graft Type, and Material Quality Matter for Implant Success

The Importance of Alveolar Bone Volume

Adequate alveolar ridge height and width are essential for successful dental implant placement. However, bone resorption commonly occurs after tooth extraction, especially when the site is not preserved with a bone graft or simultaneous implant placement.

While traumatic extractions can destroy the buccal plate, anatomical bone deficiencies are more frequently the root cause of inadequate bone volume.

Research shows that bone loss after extraction may reach up to 1.5–2 mm vertically and 3.8 mm horizontally within just six months. To prevent this, using a grafting material such as Vitality Bone allograft is critical to establish the ideal site for implant placement.

Hard tissue engineering, or bone regeneration, is widely performed by oral surgeons and implant specialists to reconstruct the alveolar ridge either before or during implant procedures.

Bone Graft Types and Their Applications

While autografts (bone harvested from the patient) are the gold standard for their regenerative potential, they require an additional surgical site. In practice, allografts (donor-derived human bone) and xenografts (animal-derived) are more commonly used due to their availability and excellent performance.

Allografts like Vitality Bone are mineralized, cell-free grafts designed to be absorbed and replaced with new, live bone over approximately four months.

Dental implant success often requires a minimum of 10 mm in bone height and 4–6 mm in ridge width—making graft selection critical for functional and esthetic outcomes.

Ideal Characteristics of Mineralized Allograft (FDBA)

Mineralized freeze-dried bone allograft (FDBA) offers key advantages in oral and implant surgery, including:

• Biocompatibility

• Biodegradability

• Mechanical strength

FDBA provides a natural scaffold with high porosity and interconnected structure. These properties support osteoblast function and promote the development of new bone by allowing cell attachment and migration.

Common Indications:

• Socket preservation

• Guided bone regeneration (GBR)

• Ridge augmentation

• Maxillary sinus elevation

• Treatment of peri-implant defects

Vitality Bone Allograft: Product Overview

Developed under the guidance of Dr. Hamid Shafie, a respected leader in implantology, Vitality Bone is processed in a U.S.-based, AATB-accredited tissue bank.

Composition:

• 70% cortical bone: Structural support and shape retention

• 30% cancellous bone: Enhanced vascularization and rapid integration

This blend delivers superior graft stability and regenerative potential, with a turnover time of approximately four months.

Turnover Rate and Particle Size

Turnover rate depends on both the technique and material characteristics:

• Cancellous particles: Resorb faster

• Cortical particles: Provide longer-term scaffolding

Vitality Bone’s 70/30 ratio offers the best of both worlds—retaining shape while remodeling in a clinically efficient timeframe.

Particle Size:

• 500–1000 microns

• Maintains space and resists compression

• Provides optimal surface area for cellular attachment

• Supports predictable healing and bone quality

Benefits of 100% Mineralized Bone Allograft

Vitality Bone is a fully mineralized FDBA, offering advantages in:

• Biocompatibility

• Space maintenance

• Structural integrity

• Osteoconduction with possible osteoinductive properties

It is suitable for a wide range of oral surgery applications including ridge preservation, sinus grafting, and GBR procedures.

FDBA vs. DFDBA: Which Is Better?

While DFDBA (demineralized bone) may offer some osteoinductive potential, FDBA like Vitality Bone is preferred in most surgical settings for its ability to:

• Promote dense bone formation

• Maintain graft shape over time

• Perform predictably in lateral ridge augmentation

Indications for Vitality Bone Allograft

• Socket preservation following extraction

• GBR ridge augmentation for implant preparation

• Maxillary sinus augmentation procedures

• Management of peri-implant bone defects

Bone Allograft Traceability and Quality Assurance

Traceability ensures surgical safety and clinical accountability. Vitality Bone is:

• Fully traceable to U.S.-based donors

• Collected under strict donor screening protocols

• Produced with robust quality systems, including:

  • Quality Assurance (QA)

  • Quality Management (QM)

  • Quality Control (QC)

Biologic Characteristics of an Ideal Bone Graft

An ideal graft should:

1. Support three-dimensional tissue ingrowth

2. Provide a scaffold for osteoblast attachment

3. Exhibit osteoinductive and osteoconductive potential

4. Maintain shape throughout healing

Vitality Bone is engineered to meet these clinical goals.

Comparison: Vitality Bone vs. Xenografts vs. Synthetic Grafts

Synthetic grafts may be used for cultural or personal reasons, but they generally lack the regenerative performance of mineralized allografts.

Summary: Why Choose Vitality Bone?

Vitality Bone offers:

• A 70/30 cortical-to-cancellous ratio

• Ideal particle size (500–1000 microns)

• ~4-month predictable turnover

• Full donor traceability

• High osteogenic potential

It is a trusted, safe, and high-performing allograft for modern oral and implant surgery.
