Abstract :

Background: Peri-implantitis is an irreversible inflammation that leads to crestal bone loss around the implant. Its symptoms include radiographic bone loss, increased probing depth, bleeding on probing, and pus discharge. This study aimed to investigate the relationship between radiographic bone analysis and clinical factors in patients with peri-implantitis.Materials and Methods: This cross-sectional observational clinical study was conducted on 38 patients with symptoms of peri-implantitis, referred to the private department and dental clinic of Isfahan Azad University. At first, by obtaining informed consent, periapical digital imaging was taken from the patient's implant with a parallel technique and the amount of vertical bone resorption was checked in millimeters. The amount of vertical bone resorption of the implant was divided into three categories: vertical bone resorption was less than 1.5 mm, between 1.5 and 3 mm, and more than 3 mm. Then, the amount of bleeding, the depth of probing, and the presence of pus were checked. Data were analyzed with t-test, ANOVA, and Pearson's correlation coefficientResults: There was a significant and direct difference between bleeding on probing and vertical bone resorption (P<0.001, r=0.466). There was also a significant and direct difference between probing depth and vertical bone analysis (P<0.018, r=0.278). The pus variable was negative for all peopleConclusion: Bleeding on probing and depth of probing have a direct relationship with vertical bone resorption in patients with peri-implantitis and with the increase of radiographic bone resorption, depth of probing and bleeding on probing increases in patients.
