简要总结
The study was conducted at the Division of Periodontology, Bolu Abant İzzet Baysal University Faculty of Dentistry. Participants were systemically healthy individuals aged 18 to 70 who had received dental implant prostheses within the past five years and had high-quality panoramic radiographs. The peri-implant status of the subjects was evaluated using various indices and radiographic analyses in accordance with Chicago's Classification of Periodontal and Peri-Implant Diseases and Conditions. Additionally, measurements of gingival thickness, gingival phenotype, keratinized gingival width, and emergence angle were performed.
详细描述
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.

结局指标
主要结局
Emergence angle
时间窗: Baseline
EA was determined by measuring the angle formed between the long axis of the implant and a tangent line drawn to the restoration. A line was initially drawn along the long axis of the implant at its outside collar. Subsequently, a second line, tangent to the restoration, was drawn from the platform. The angle at which the junction occurred was recorded as the EA .
