Sammanfattning
Lost teeth are increasingly replaced by implant retained prosthetic restorations. An increasing number of implants installed may lead to more complications and mistakes. Peri-implantitis is a biological complication around an osseointegrated implant. In the litterature there is growing documentations indicating that loss of osseointegration is a more complex process than previously assumed where foreign body reaction, titanium allergy, micromovements and occlusal overload might be important causative factors in addition to plaque induced infection. Because the total picture of etiological factors is unclear, optimal protocols for the treatment of peri-implant complications are not available.
The objective of this article is to present knowledge about non-infective conditions that may contribute to loss of osseointegration following successful implant placement and discuss potential causal mechanisms. A documented case illustrates loss of osseointegration after 3 years in function showing no clinical signs as bleeding or pus of peri-implant disease. Based on clinical and radiographic features occlusal overload seems to be an important causal factor.
