Surgical and Non-surgical Treatment of Peri-implantitis
A study testing Surgical treatment and Non-surgical treatment in people with Peri-implantitis, run by Federal University of Rio Grande do Sul at 1 site in Brazil.
Trial summary
This study will compare surgical and non surgical treatments of peri-implantitis. Peri-implantitis is an inflammation around dental implants that can lead to the loss of the implant over time if no treatment is established. The signs of peri-implantitis included bleeding of the gingiva, swelling and redness. Read more about this study

About this study
Official title: Surgical and Non-surgical Treatment of Peri-implantitis: Multi-center Randomised Controlled Trial of 12-months Follow-up
This study will compare surgical and non surgical treatments of peri-implantitis. Peri-implantitis is an inflammation around dental implants that can lead to the loss of the implant over time if no treatment is established. The signs of peri-implantitis included bleeding of the gingiva, swelling and redness. Most of times there is no pain. Patients presenting with these characteristics will be included at random to one of the treatment groups. Those allocated to the non-surgical group will received implant cleansing after local anesthesia using adequate instruments. In the surgical group, patients will be submitted to a surgical procedure around the implant for visualization and cleansing also after local anesthesia. All patients will be followed over a 12-month period. The hypothesis is that surgical treatment is better than non-surgical treatment regarding clinical, radiographic, microbiological, and immunological.characteristics.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study will compare surgical and non surgical treatments of peri-implantitis. Peri-implantitis is an inflammation around dental implants that can lead to the loss of the implant over time if no treatment is established. The signs of peri-implantitis included bleeding of the gingiva, swelling and redness. Most of times there is no pain. Patients presenting with these characteristics will be included at random to one of the treatment groups. Those allocated to the non-surgical group will received implant cleansing after local anesthesia using adequate instruments. In the surgical group, patients will be submitted to a surgical procedure around the implant for visualization and cleansing also after local anesthesia. All patients will be followed over a 12-month period. The hypothesis is that surgical treatment is better than non-surgical treatment regarding clinical, radiographic, microbiological, and immunological.characteristics.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pocket depth reduction (time frame: 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Oct 2019; AzTrials last refreshed its copy on 8 Nov 2026.
