Brief summary

Implant patients who applied to Bolu Abant İzzet Baysal University provided anamnesis. The study included 165 people with 272 implants. The study includes implants that satisfied the inclusion criteria. Plaque index (PI) \[13\], gingival index (GI) \[14\], bleeding on probing (BOP) \[15\], periodontal pocket depth (PPD), clinical attachment level (CAL), gingival recession (GR), GP, GT, and KTW were all assessed in every implant patient. The presence of peri-implant mucositis or peri-implant health was assessed using the collected indices and radiographs. The patients were split into two groups: those with peri-implant mucositis (136 implants) and those with peri-implant health (136 implants). We investigated the relationships between each parameter and periodontal health.

Interventions

OTHERImplant

The classification of peri-implant diseases is based on clinical and radiographic criteria, distinguishing between peri-implant mucositis and peri-implantitis according to the presence of inflammation and bone loss.

Inclusion criteria

* Patients aged 18-65 years who were systemically healthy, had a controlled medical conditions, and had fixed prostheses on the implants for at least 1 year following functional prosthetic loading of the dental implants.

Exclusion criteria

* Individuals with bruxism; those who smoke, were pregnant, or were breastfeeding; those who used anti-inflammatory drugs, immunosuppressants, or medications affecting the mucosa and bone; those who had undergone peri-implant disease treatment after implant placement; and those with residual cement residue and peri-implantitis related to prosthesis design or incorrectly placed implants.

Design outcomes

Primary

MeasureTime frameDescription
Gingival phenotypeBaselineIf the probe was visible when placed in the sulcus, gingiva was classified as thin (≤1 mm), and if the reflection of the probe was not visible, it was classified as thick (\> 1 mm).

Secondary

MeasureTime frameDescription
Periodontal pocket depthBaselineThe periodontal pocket depth is the measurement of the distance between the gingival margin and the most coronal region of the junctional epithelium.
Bleeding on probingBaselineThe bleeding on probing index was established as the occurrence of bleeding in the sulcus, thirty seconds after measuring the depth of the periodontal pockets in all dental implant.
Plaque indexBaselineAn index for estimating the status of oral hygiene by measuring dental plaque that occurs in the areas adjacent to the gingival margin. 0 is minimum and 3 is maximum. The situation worsens as the score increases.
Gingival indexBaselineThe Gingival Index (GI) scores each site on a 0 to 3 scale, with 0 being normal and 3 being severe inflammation characterized by edema, redness, swelling, and spontaneous bleeding. 0 is minimum and 3 is maximum.
Clinical attachment levelBaselineThe peri-implant clinical attachment level is determined by measuring the distance from the implant margin to the base of the mucosal sulcus using a Williams periodontal probe.
Gingival recessionBaselineGingival recession is the measured distance between the enamel-cementum and the gingival margin. Assessment was performed using a Williams periodontal probe.
Gingival thicknessBaselineGT was measured by inserting a number eight canal file from the buccal side of the implant until it reached the alveolar bone and then securing it with a stopper to determine the distance.
Keratinized tissue widthBaselineThe width of the keratinized gingiva was measured via a periodontal probe from the mucogingival margin to the gingival margin.
