The Effect and the Potential Use of Magnetic–Dam Barrier in Guided Bone Regeneration: A Laboratory Study

Guided bone regeneration (GBR) has been shown to be an optimal technique accelerate the process thanks action of membrane barriers that promote tissue healing through osteogenesis, inducing repopulation with osteoprogenitor cells prevent invasion non-osteogenic tissue. However, current membranes, such as expanded polytetrafluoroethylene or rubber dam, have some disadvantages could potentially reduce effectiveness GBR. Recently, scaffolds magnetic properties tested rapid osteogenesis. The aim this laboratory study was evaluate intensity field generated by a custom-made dam magnetised neodymium-iron-boron (Nd2F14B) (three layers latex filled Nd2F14B powder on inner surface) and understand effects cell viability. A 750 G, 400 900 G surface long wide sides 3 2 cm in contact dam. At distance 1 mm from 300 150 measured respectively. After 72 h, MG-63 osteoblast-like line showed slight decrease proliferation (85 ± 10) compared unmodified (95 6) control population. According our findings, cofferdam is able generate static significantly affect contrast other nonabsorbable membranes. Further studies subsequent clinical trials are needed significant improvements can achieved using type
