Bone Grafting With Split Bone Block Technique (Khoury Technique) – Management of Hard and Soft Tissue – Thomas Hanser, DMD, MSc, MSc, MOM

Recorded on April 9th, 2025

Description:

This webinar will describe the indication, scientific background and the clinical implementation of the so-called Split Bone Block Technique (Khoury Technique). This alveolar augmentation technique is based on the use of autogenous bone transplants, which are harvested intraorally using a safe and minimally invasive protocol. A specific preparation of the autogenous bone grafts is demonstrated to increase their biological potential and accelerate their healing.

In addition to stabilizing the bone grafts, their hermetic soft tissue closure using innovative flap designs is also shown. In addition to shortening patient treatment time, the grafting technique demonstrated enables predictable and long-term stable volumetric and biological tissue stability in the context of lateral and vertical alveolar ridge augmentation. The philosophy of the Split Bone Block Technique is documented in the webinar through numerous different clinical cases and surgical videos.

Upon completion of this presentation, participants should be able to:
1) Select appropriate anatomical structures and instruments for safe and minimally invasive intraoral bone graft harvesting.
2) Describe the specific preparation of autogenous bone grafts to increase their biological potential, accelerate their healing and shorten patient treatment time.
3) Identify the clinical and biological factors for predictable, reproducible, volumetric and biological long-term tissue stability with autogenous bone grafts in lateral and vertical alveolar ridge augmentation.
