Fig. 5-111. Behrman's method of burying magnets in the bone. A, First, the tissues overlying the alveolar crest are incised. B, The tissues are reflected and held away from the bone by sutures. C, A site is created for the magnet, which should lie flush or close to the superior border of the crest. D, The magnetized implant is set in place, using an orangewood stick to position it. E, A tantalum mesh, trimmed so that no more than 1 mm. rests on the marginal bone, is tried over the site. The magnet is sealed to the mesh with polytetrafluoroethylene to immobilize it. If the site is so exact that the magnet maps into place, the mesh is not needed. Once the magnet is in place, the site is irrigated and closed, suturing both the periosteum and mucosa over the site.
