Two piece dental implant by Nobel Biocare
Different zirconia dental implant systems have been developed for the replacement of damaged or missing teeth and two different zirconia implant designs are available on the market: one-piece restorations and two-pieces restorations. One-piece restoration systems show high fracture resistance and expose minimal surface area susceptible for hydrothermal aging. A drawback is that the restorations (final or provisional) need to be cemented to the abutment, a procedure that can increase the plaque accumulation in this area. The two-piece restoration is a screw-retained implant system such as the NobelPearl™ ceramic implant by Nobel Biocare shown in the video above.
