About this trial

This is an interventional screening trial for Peri-Implantitis focused on measuring implant, titanium, dental

Eligibility Criteria

25 Years - undefined (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • Is the subject ≥ 25 years of age?
  • Does the subject have an implant with a probing depth ≥ 5mm, bleeding on probing, and radiographic bone loss of > 2mm?
  • Is the subject committed to the study and the required follow-up visits?

Exclusion Criteria:

- Is the subject immune compromised? Is the subject diabetic? Does the subject take steroid medication? Does the subject regularly use non-steroidal anti-inflammatories? Is the subject pregnant or intending to become pregnant during the duration of the study? Has the subject had previous implantoplasty? Did the subject take any antibiotics in the last 3 months?

Outcomes

Primary Outcome Measures

Titanium Dissolution
The primary outcome of the clinical trial will be titanium dissolution in periimplant plaque following treatment quantified using inductively coupled mass spectrometry (ICMS)

Secondary Outcome Measures

Expression of pro-inflammatory cytokines in response to titanium
We will determine whether PBMCs from peri-implantitis persons and controls have a differential pro-inflammatory response to titanium particles.

5. Study Description

Brief Summary
Peri-implantitis is an inflammatory disease that leads to loss of jawbone around dental implants. Recent discoveries have identified increased release of Titanium (Ti) particles around implants as being associated to peri-implantitis. In this ancillary study to the Dental Hygiene and Peri-Implant Tissues Homeostasis trial the objective is to determine potential triggers of increased Ti dissolution from the implant surface and the mechanisms by which Ti dissolution products amplify peri-implant inflammation. Results from this study will determine whether there is a differential response to Ti particles across individuals, which may alter susceptibility to peri-implantitis.
