Achromat Esthetic Fiber Posts feature: High strength and low elastic modules for mechanical compatibility with dentin. Tooth-colored, for optimal esthetics, especially under all-ceramic crowns. Serrated and machined surface to provide maximum surface area and bond ability. Radiopaque, for diagnostic accuracy. Made of the highest-quality fibers, for high flexural strength. Bonded, rather than cemented, for extra retention and low solubility. Cannot corrode like stainless steel; for real long-term biocompatibility.
