Implantology is the branch of dental medicine that has gone through the greatest development and progress in recent years. A large number of implants also led to the development of periimplantitis. Peri-implantitis is a condition characterized by bleeding on probing, increased probing depth compared to previous measurements, and loss of alveolar bone on the radiograph compared to the initial radiograph after the bone remodeling phase. It occurs with the progression of periimplant mucositis, which is characterized by bleeding, edema and erythema, but bone loss is absent compared to peri-imlantitis. Abutment is a prosthetic element that represents the connection between an osseointegrated implant in the bone and the prosthetic superstructure that attaches to it. It is attached to the implant with a retention screw, and serves as a support for the prosthetic replacement. Abutment can be fixed to the implant with an external and internal connection, and the internal connection can also be in the form of a conical connection. The most common materials from which abutments are manufactured are titanium and zirconium oxide ceramics. The prosthetic superstructure can be retained on the abutment with cement and screw. The most significant problems that occurs with the connection of implants and abutments are micro-loosening, micro-movements and screw loosening. Research has shown that the abutment profile should be flat or concave with an emergence profile <30 °. The material from which the superstructure is manufactured does not hold a great significance if the surfaces are well polished and have adequate seating, however zirconium oxide is still recommended for abutments in the anterior region. The method of retention of the prosthetic superstructure with a screw gives better results. Oral hygiene and regular recalls along with professional clening are also important factors in prevention of periimplantitis.
