IMPLANT INSERTION WITH CRESTAL EXPANSION USING THE MAGNETIC MALLET

Author: Dr. Libertucci Mauro

The Magnetic Mallet is a device that uses magneto-dynamic technology to manipulate bone tissue. The force transmitted to its inserts is similar, but not comparable, to the one obtained by beating with a surgical hammer. It is not comparable because the force exerted by the Magneto-Dynamic technology is much more intense but lasts for an extremely shorter time than a manual. Thus, not only is the impact perceived by the patient as less invasive, but it is also possible to perform multiple operations, such as creating implant sites by compaction rather than by subtraction (as happens with rotating drills) and bone shaping by displacement of bone tissue .

This case is extremely didactic because it shows a ridge in areas 24 and 25 with evident resorption of the vestibular cortex treated at different times and with different methods. In fact, in 2001 a first implant was inserted in zone 24, regenerating the missing tissue in the vestibular area with a GBR using bovine bone as an osteoconductive scaffold, and in 2019, following the accidental fracture of the bridge, a second implant was inserted in zone 25 using the Magnetic Mallet to create the implant osteotomy and at the same time expand the ridge buccally. After 4 months at the reopening of the site, it is possible to notice how the expanded ridge area has the same level as the regenerated ridge area with the difference that the expanded area is totally composed of the patient’s bone while the regenerated area (as shown in the SEM photos and from the histological preparation) is a tissue composed of areas of bone but for the most part of bags of infinitesimal grains of crystallized hydroxyapatite which, when the microtome is cut, are dispersed, leaving empty gaps in the preparation. This demonstrates the countless advantages of this equipment which allows us to be minimally invasive, not to use biomaterials, to work in the absence of aerosols with a final result superior to other methods.
