Strong adhesions between dental materials and between prostheses and tooth structures are key to successful clinical restorations. Plasma, which is produced by partial or complete ionization of gas under high energy, is a safe gas cloud with high efficiency, low energy consumption, and without secondary pollution. Plasma can change the surface structure of polymers and form an inert surface-protective layer that improves material wetting, biocompatibility, and durability. Moreover, surface treatment with plasma can increase the adhesive strength between various substrates and acrylic resin bases, fiber-reinforced complex materials, glass-ceramic materials, polycrystalline ceramics, and composite resin. This research investigates plasma bonding of dental materials to provide theoretical bases for wide plasma applications in dental clinics.
