NCT07295743

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Emergence angle

    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 .

    Baseline

Secondary Outcomes (8)

  • periodontal pocket depth

  • bleeding on probing

Study Arms (3)

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.

Other: emergence profile

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.

Other: emergence profile

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.

Other: emergence profile

Interventions

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