01 — HARD TISSUE
Bone support
Grafts and bone-void fillers can maintain space, provide a scaffold, or fill a defect while bone forms and remodels.
Clinical Education
See how regenerative biomaterials are used in dental, orthopedic, and wound-care settings--from placement to healing.
The fundamentals
Regenerative biomaterials are selected for the tissue being treated, the shape and location of the defect, and the clinical objective.

01 — HARD TISSUE
Grafts and bone-void fillers can maintain space, provide a scaffold, or fill a defect while bone forms and remodels.

02 — SOFT TISSUE
Membranes, matrices, and collagen scaffolds can protect a site, guide healing, or reinforce repaired tissue.
Clinical applications
Select a clinical area to explore typical uses. The precise indication, handling method, and expected outcome depend on the specific product and patient.
01

Hard tissue
Bone grafting materials are placed into a prepared defect to provide space and a scaffold for new bone formation.
Soft tissue
Resorbable or non-resorbable barrier membranes separate faster-growing soft tissue from the bone-regeneration space. Other collagen materials may protect oral wounds.
02

Hard tissue
Bone-void fillers occupy surgically created or traumatic defects that are not essential to the immediate stability of the bone. Product-specific formulations may have specialized uses.
Soft tissue
A biologic scaffold may be positioned over or around repaired tissue to add reinforcement while the patient’s tissue heals. It does not replace the primary repair.
03

Soft tissue
Collagen-based powders, matrices, and tissue-derived coverings may help manage the wound environment and provide a scaffold for cell migration and new extracellular matrix deposition.
Clinical literature
Selected peer-reviewed resources provide a starting point for understanding the clinical evidence supporting regenerative biomaterials across dental, orthopedic, and wound-care settings.

Most products provide a scaffold, barrier, filler, or reinforcement that supports the body’s healing process. The biological response varies by material, procedure, and patient.
Some materials resorb or remodel over time, while others are designed to remain. Your clinician should explain the specific product selected for your procedure.
No. Products that look similar can have different cleared or approved indications, contraindications, handling instructions, and clinical evidence.
Ask what material will be used, why it was selected, its source, whether it resorbs, important risks, alternatives, and what to expect during recovery.
