Effect of Emergence Angle on Peri-implant Status

Patient histories were collected from those who met the study criteria, and panoramic radiographs were taken. A total of 310 implants were initially assessed, and 192 implants were selected for inclusion in the study. All implant patients underwent an evaluation of plaque index , gingival index, bleeding on probing , pocket depth, clinical attachment level, and gingival recession. The peri-implant condition was determined using these indices and radiographs, in accordance with the guidelines from the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions and the 2023 European Federation of Periodontology. Patients were categorized into three groups: peri-implantitis (64), peri-implant health (64), and peri-implant mucositis (64). Additionally, gingival thickness (GT), keratinized gingival width (KGW), and gingival phenotype (GP) around the implants were measured, and the emergence angle (EA) of the implants was calculated.
