Abstract
Introduction
Although
peri-implant bone loss is one of the parameters included in the
criteria for determining implant success, its prevention is of vital
importance. The goal of this article is to assess the factors that
affect peri-implant bone loss.
Material and methods
An
observational, longitudinal, retrospective study was conducted in 148
partially edentulous patients rehabilitated with implants and with a
follow-up period of 5 years or more. A total of 585 implants were
included in the study. Radiographic peri-implant bone loss was compared
with radiographic periodontal bone loss, and other characteristics such
as prosthesis design, hygiene, and implant size were studied as
potential peri-implant bone loss modification factors.
Results
In the univariate analysis, a statistically significant relationship between peri-implant bone loss and gender (P < 0.05), implant system (P < 0.01), reason for extraction (P < 0.05), splinting (P < 0.0001), and distance between the implant platform and the horizontal component of the prosthesis (P < 0.0001) were observed. In multivariate analysis, the relationship between this peri-implant loss and gender (P < 0.05), implant system (P < 0.05), splinting (P < 0.001), and the aforementioned distance (P < 0.01) remains.
Conclusions
The

the greatest effect on peri-implant bone loss This distance must be
