What I Learned from Professor Khoury’s Advanced Bone Grafting Course

Last week, I had the privilege of attending an advanced bone regeneration course with Dr. Fouad Khoury-an undisputed leader in the field of advanced bone grafting.

Dr. Khoury has pioneered many of the techniques that are now taught by top educators in dental surgery around the world. A highly sought-after lecturer, he has traveled extensively and studied bone regeneration techniques globally, refining and systematizing approaches that prioritize biology, long-term stability, and predictable outcomes.

Why Do We Perform Bone Grafting?

Many patients seeking dental implants simply do not have an adequate volume of bone to properly support them. A helpful analogy is placing a large plant into a container that’s too small—without enough foundation, long-term stability is compromised.

In some cases, implants are placed in narrow ridges or shallow bone in an effort to reduce treatment time or cost. However, biology and function ultimately prevail. The forces of mastication combined with natural bone remodeling can lead to bone loss over time—whether crestal bone loss around the implant collar or buccal bone loss along the facial aspect. Long-term success requires respecting the biology of bone and creating sufficient volume to withstand functional load.

Types of Bone Grafting Materials

Bone grafting materials vary by region and philosophy:

• Allograft (United States): In the U.S., processed human donor bone is predominantly used. These grafts are rigorously screened and processed in accordance with FDA and AATB standards.

• Xenograft (Europe): In many European countries, bovine-derived xenografts are more commonly utilized. A widely known example is Bio-Oss.

• Synthetic Options: Laboratory-produced grafting materials are also available, along with plant-based or seaweed-derived “vegan” bone substitutes.

Each material has its indications, benefits, and limitations.

The Gold Standard: Autograft

Despite the variety of materials available, the gold standard remains autogenous bone grafting—harvesting bone directly from the patient, typically from an intraoral donor site.

The advantages are significant. Autogenous bone retains living cells and biologic activity. It supports natural remodeling and releases bone morphogenetic proteins (BMPs), which stimulate pluripotent stem cells and osteoblasts to form new bone. This biologic potential allows for more predictable integration and long-term stability.

One of the key takeaways from Dr. Khoury’s course was this: successful implant dentistry is not about simply placing an implant—it’s about building and preserving the biologic foundation that supports it for decades. Respect the biology, create adequate volume, and long-term function will follow.
