Dental implant infection study tracks patient experience through treatment
NCT ID NCT07694323
First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This study follows 45 adults with peri-implantitis—an infection around dental implants—to see how treatment affects their oral health-related quality of life and pain. Researchers measure patient-reported outcomes at diagnosis, after non-surgical and surgical treatments, and at a 6-month follow-up. The goal is to understand what patients experience during therapy, not to test a new treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help dentists tailor peri-implantitis treatments to improve patient comfort and quality of life.
- What could go wrong
- This is an observational study with only 45 participants, so findings may not apply to all patients. It measures patient experiences, not treatment effectiveness.

Who is studied
Adults (≥18 years) diagnosed with peri-implantitis according to the 2017 World Workshop classification who require surgical treatment following non-surgical therapy. Participants will be recruited from the Departments of Periodontology at the Hospital Odontològic Universitat de Barcelona (HOUB), the Clínica Universitària d'Odontologia of the Universitat Internacional de Catalunya (CUO-UIC), and the Universitat de València (UV).

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
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.
