The influence of plaque and/or excessive loading on marginal soft and hardtissue reactions around Branemark implants: A review of literature and experience

High implant survival rates are published with more than 15 years of observ ation time. Failures over time are often caused by ongoing marginal bone lo ss. Therefore, the need for reliable monitoring of the stability of periimp lant attachment and/or bone level is extremely important. Marginal bone los s around osseointegrated implants has often been associated with periimplan titis, but clinical observations cannot prove this relationship. Otherwise, the impact of excessive loading on periimplant bone has been shown in anim al studies and has been positively related to implant failure in terms of i mplant mobility and marginal bone loss. Some clinical observations support this hypothesis.
