Biomechanical Stability of Dental Implants in Augmented Maxillary Sites: Results of a Randomized Clinical Study with Four Different Biomaterials and PRF and a Biological View on Guided Bone Regeneration

Figure 3

Macroscopical clinical demonstration of clean detachment of the periosteum from the bone with Piezotome surgery utilizing the cavitation effect: no remnants of the osteogenic layer of the periosteum are visible on the bone; the perforating blood vessels are cleanly cut.
