The bone preparation block - an interesting instrument in the oral surgery
Stoetzer, Marcus / Rana, Majeed / von See, Constantin / Gellrich, Nils-Claudius
Introduction: Augmentation procedures in preimplant surgery uses a standard method. Different methods for extraction and processing of autologous bone used. The acquisition of bone chips and the the harvesting of bone blocks. Bone blocks and chips are both brought to the place where they are needed for augmentation, wherein the bone block is fixed by means of osteosynthesis in the final position. For a successful osseointegration not only the safe seat of the bone is important, but also a corresponding conturation in which the graft must be securely fixed, which often represents a challenge to the clinician. This are exactly the reasons why the bone-preperation block was developed.
Material and Method: With more than 300 patients were anatomically shaped bone graft from different points, taken with different dimensions. In the preperation block, they were worked with rotating and oscillating process outside the mouth. After processing, the bone was to be augmented in the situs and the fixation with osteosynthesis.
Results: In all patients the secure fixation of the samples collected and to ensure extra-oral bone graft conturation under water cooling. None of the patients broke the bone or damaged by excessive pressure in texture. Late graft losses were not as well.
Discussion: Safe fixation is a must for the extra-oral work, under water cooling, to augmenting of autologous bone blocks. Even the use of bonescrapers clamped on bone is ensured due to the secure fixation. The preperation block is therefore a useful and necessary complement to the existing augmentation sets.
