Abstract: At the beginning of every implantological intervention - especially in compromised situations- there is the reconstruction of the intraoral bony defects. For predictable and long-term stable results, the choice of the procedure and the implementation of the technique by the surgeon are of crucial importance.

In the presented procedures, the Biological Bone Augmentation (BBA concept) and the Split bone block technique SBBT (according to Prof. Fouad Khoury) are presented, in which preferably the patient's own and vital bone is used as the so-called "Gold standard". The advantage lies in the osteoinductive and osteogenetic potency of the autologous bone. At the same time, innovative modifications are presented, which may represent a facilitation and simplification of the previous methods.

In this context, the careful, safe and at the same time time-saving harvesting of the bone as well as the safe reconstruction of the defects are discussed in particular.

Learning Objectives:

1. Acquire an understanding of how to harvest cortico-cancellous bone blocks from the external oblique line.
2. Learn the BBA Concept (Biological Bone Augmentation with pure autogenous bone) and the Split Bone Technique (by Prof. Khoury).
3. Learn how to deal with advanced bone defects, including vertical defects and importance of advanced soft tissue management techniques in the context of bone augmentation.
4. Identify complications in treatment and learn a new approach in bone harvesting to simplify the procedure.
