Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Peri-implantitis

Peri-implantitis patients are those who have developed inflammation around a dental implant, leading to the loss of supporting bone and the presence of pockets of infection.

emergence profile

Intervention Type OTHER

The emergence angles of the implants were measured on panoramic radiographs.

Peri-implant mucositis

Peri-implant mucositis refers to a reversible inflammatory condition affecting the soft tissues surrounding a dental implant, characterized by redness, swelling, and bleeding on probing, without any bone loss.

emergence profile

Intervention Type OTHER

The emergence angles of the implants were measured on panoramic radiographs.

Peri-implant health

Peri-implant health refers to the condition where the tissues surrounding a dental implant are free from inflammation, with no signs of redness, swelling, bleeding on probing, or bone loss, indicating a stable and healthy implant environment.

Intervention Type OTHER

The emergence angles of the implants were measured on panoramic radiographs.
