The goal of this clinical trial is to learn whether a home-use light device helps control gum inflammation around dental implants in adults who have a full set of fixed teeth attached to implants. This gum inflammation, called peri-implant mucositis, is common and reversible, but can lead to more serious problems if it is not controlled. The device is meant to be added to the usual professional cleaning and hygiene care, not to replace it.
The main questions it aims to answer are:
* Does adding the home-use light device reduce gum bleeding around the implants more than the usual care alone? * Does it reduce the depth of the space around the implants and the amount of harmful bacteria?
Researchers will compare adults who receive the usual professional care plus the home-use light device with adults who receive the usual professional care alone, to see if the device improves gum health.
Participants will:
* Receive professional cleaning and personalized instructions on how to keep their implant teeth clean at the start of the study. * Be placed by chance into one of two groups: usual care plus the home-use light device, or usual care alone. * Use the light device at home each day for 4 weeks (if in the device group) * Visit the clinic at the start, after 2 weeks, and after 4 weeks for gum checkups and to have bacteria samples taken.
