To evaluate longitudinal changes in oral health-related quality of life (OHRQoL) and other patient-reported outcomes (PROMs) throughout the different stages of peri-implantitis therapy, including diagnosis, non-surgical treatment, surgical treatment, and 6-month follow-up. Secondarily, to explore the influence of clinical, implant-related, and surgical factors on patient-reported outcomes and treatment experience.

Inclusion Criteria:
* Adults (≥18 years) diagnosed with peri-implantitis according to the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions (Berglundh et al., 2018).
* Implants presenting bleeding on probing (BoP) and/or suppuration on probing (SoP), increased probing depth, and progressive bone loss compared with previous records.
When previous records are unavailable, implants will be included if they present bleeding and/or suppuration on gentle probing, probing depth ≥6 mm, and a bone level ≥3 mm apical to the most coronal portion of the rough implant surface.
\- For patients requiring multiple peri-implantitis surgeries, only the first surgical intervention will be included.
Exclusion Criteria:
* Patients who, following non-surgical peri-implantitis treatment, present ≤1 site with isolated bleeding on probing, no suppuration on probing, probing depths ≤5 mm, and no progressive bone loss compared with pretreatment bone levels.
* Contraindications to surgical peri-implantitis treatment, including plaque index \>20% and bleeding on probing \>10%.
* Previous radiotherapy to the head and neck region.
* Uncontrolled diabetes mellitus/hyperglycaemia (HbA1c \>7%).
* Pregnancy or breastfeeding at the time of enrollment.
* Alcohol or substance abuse.
* Previous surgical treatment of peri-implantitis at the same implant.
* Inability to complete the postoperative pain assessment (VAS) or the oral health-related quality of life (OHRQoL) questionnaires.
Primary outcome measure(s)
Change in Oral Health-Related Quality of Life (OHRQoL) — T0 (immediately after diagnosis), T1 (6 weeks after non-surgical treatment), T2 (6 weeks after surgical treatment), and T3 (6 months after surgical treatment) Change in oral health-related quality of life throughout peri-implantitis treatment, assessed using the Spanish version of the Oral Health Impact Profile-14 (OHIP-14sp). The total OHIP-14sp score ranges from 0 to 56, with higher scores indicating worse oral health-related quality of life. The outcome will be expressed as the total OHIP-14sp score and compared across the four study time points.
Unit of Measure: OHIP-14sp total score (0-56)
