The soft tissue around dental implants serves as a protective barrier between the oral cavity and the underlying bone. These peri-implant tissues are recurrently challenged my numerous hazards that can have adverse effects on the implant longevity, such as plaque, load, and prosthetic interference. The implant abutment material seems to be of decisive importance for the quality of the attachment between the mucosa and the surface of the abutment. Different materials are available for the fabrication of implant abutments. Because of their dark color, metal abutments were reported to cause a grayish discoloration of the surrounding soft tissues, compromising the esthetic outcome in the esthetic zone. Ceramic abutments are of increasing interest, not only because of their tooth-like color but also for their possible biologic advantages. Although there is currently no mutual consent that ceramic abutments perform superior to titanium alloy abutments, the results of human histology studies indicate, that zirconium-dioxide may have a more favorable effect on the health of the peri-implant tissues.

However, achieves a high strength due to the metal internal connection with the implant and the metal/titanium insert or base.
