The Problem: Bone Loss After Tooth Extraction
When a tooth is lost or extracted, the surrounding alveolar bone begins to resorb. Studies show that up to 50 % of ridge width can be lost within the first 12 months. Without adequate bone, placing a dental implant becomes difficult — or impossible.
What Is Bone Grafting?
Bone grafting is a surgical procedure that replaces missing bone with a graft material. The material acts as a scaffold, encouraging the body's own cells to regenerate new bone tissue over time.
Types of Bone Graft Materials
Xenograft (Bovine-Derived) Derived from processed bovine bone, xenografts offer excellent osteoconductive properties and slow resorption rates — ideal for ridge preservation and sinus lifts. Kindway BioReZens' xenograft granules are deproteinised and gamma-sterilised for maximum safety.
Alloplastic (Synthetic) Hydroxyapatite (HA) and β-tricalcium phosphate (β-TCP) ceramics mimic natural bone mineral. They are 100 % synthetic, eliminating any risk of disease transmission, and are available in various particle sizes for different clinical scenarios.
Allograft (Human-Derived) Processed from donor human bone tissue, allografts combine osteoconductive and osteoinductive properties. They are most commonly supplied as demineralised bone matrix (DBM).
Autograft (Patient's Own Bone) Harvested from the patient's own body (e.g., chin, ramus, or iliac crest), autografts are the gold standard because they contain living cells. However, they require a second surgical site, increasing morbidity.
When Is Bone Grafting Needed?
- Socket preservation — immediately after extraction to maintain ridge volume
- Ridge augmentation — before implant placement in a resorbed ridge
- Sinus lift — to increase bone height in the posterior maxilla
- Peri-implant defect repair — to address bone loss around existing implants
Clinical Success Rates
Guided bone regeneration (GBR) with barrier membranes and particulate grafts reports success rates of 90–97 % in peer-reviewed literature, making it one of the most predictable procedures in modern implant dentistry.
