About

The present study represents an extension of the previously concluded randomized clinical trial "Laser-Assisted Regenerative Surgical Therapy for Peri-implantitis" (HUM00124386). The aim of the study is to compare the adjunctive effect of laser over mechanical debridement alone in the maintenance of peri-implant tissues after surgical treatment of peri-implantitis (gum disease around implants).

Full description

The same 24 subjects, previously treated with surgical regenerative treatment of peri-implantitis following the LARST protocol, will be invited to return for three follow-up visits. During the follow-up visits, clinical measurements, x-rays, and pictures of the inside of their mouth will be taken to evaluate the success of their peri-implantitis treatment. If needed, additional laser treatment of the dental implant may also be provided according to the same randomization of subjects in the original study. No placebo laser application will be provided.

Enrollment: 16 patients

Sex: All

Volunteers: No Healthy Volunteers

Inclusion criteria

• Subjects who were previously enrolled subjects in the randomized clinical trial of laser-assisted regenerative surgical therapy

Exclusion criteria

• Unable to reach the subject
• The implant is mobile or lost

Premature Exclusion Criteria:

• The researcher believes that it is not the best interest of the subject to stay in the study
• If the subject becomes ineligible to participate based on the exclusion criteria
• If the subject's medical condition requires interventions which preclude involvement in the study (radiation therapy, chemotherapy, etc.)
• If the subject does not follow study related instructions
• The study is suspended or canceled.
