Infectious and inflammatory factor of resorption of peri-implant tissues. Literature review

Abstract

Today, in clinical practice, the loss of marginal bone mass around dental implants in the early stages after the installation and opening of the implant is increasingly common. Early clinical publications suggested that this bone loss occurred during the first year of prosthetics. Thus, numerous attempts have been made to minimize or eliminate such bone loss. However, the timing and cause of bone loss are not always obvious. The purpose of this review was to analyze data on marginal bone loss around dental implants in terms of biological implications to help understand changes in marginal bone around dental implants. One hypothesis for bone loss around dental implants has been related with infected interface between the implant and abutment. This review article shows that bone loss of 1.5 to 2.0 mm occurred around implant-abutment junctions at the bone level. The bone loss level was correlated with implant-abatement interface size. Recent publications indicate that such dental implant systems with large prosthetic-implant gaps may cause peri-implantitis with further implant loss.
