medium term follow up of peri-implantitis treatment
Brief summary
This study is a medium-term (6-9 years) follow-up of the health of the tissues surrounding the implant which was treated for peri-implantitis (peri-implant infection) in an already completed study with a 12 month follow-up. Patients who were treated in a randomised controlled trial with a 12 month follow-up will be invited to attend for examination of the implant and an x-ray to assess the bone levels at the implant. Participants will be asked to complete a questionnaire about their overall satisfaction following treatment.
Detailed description
Follow-up of 40 participants who were already enrolled in a randomised controlled trial comparing access flap with and without guided bone regeneration for the treatment of peri-implantitis. The 12 month outcomes have been published. doi: 10.1111/clr.14116 This study will provide a medium term (6-9 years) follow-up of the participants Participants will be invited to attend an examination. Full mouth probing Full mouth bleeding and plaque scores Peri-implant probing depth and recession measurements at the treated implant An intraoral radiograph to evaluate marginal bone levels at the treated implant Questionnaire to evaluate satisifaction with the treatment Participants will receive maintenance care at the treated implant.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of implants with peri-implant health | minimum 6 years | implant present + peri-implant probing depths ≤ 5 mm + absence of bleeding BOP ( 1 spot of bleeding allowed) + absence suppuration + no additional bone loss as compared to baseline measures |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| peri-implant probing depth (mm) | minimum 6 years | probing depth at 4 sites per implant. Deepest peri-implant probing depth |
| peri-implant bleeding on probing (presence or absence) | minimum 6 years | number of sites with presence or absence of BOP |
| peri-implant suppuration (presence or absence) | minimum 6 years | presence or absence of suppuration on probing or palpation |
| peri-implant mucosal recession (mm) | minimum 6 years | level of peri-implant mucosa measured from fixed a reference point as compared to baseline |
| radiographic marginal bone level (mm) compared to bone level at baseline | minimum 6 years | from intraoral radiograph |
| patient reported outcomes on VAS scale 0 - 100 mm | minimum 6 years | VAS questionnaires - regarding overall satisfaction with appearance of implant following treatment, overall satisfaction with implant treatment, Would you have had an implant if you had known you would need the treatment. Do you have pain at the implant site, do you have a bad taste from the implant site. |
| radiographic marginal bone level ( mm) compared to 12 month marginal bone level | minimum 6 years | mesial and distal radiographic marginal bone levels (mm) compared to the marginal bone levels at 12 months following treatment |
