About this study
Official title: Therapeutic Peri-implant Maintenance with Laser Therapy: an Extension of the LARST Study
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).
Read the detailed 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Periodontal Probing Depths (PD)
PD will be measured in millimeters. Change in PD measurements were calculated between baseline and 24 weeks
Measured: Baseline and 6 months
Secondary outcomes (2)
Change in Clinical Attachment Level (CAL)
CAL will be measured in millimeters. Change in subject CAL measurements were calculated between baseline and 6 months.
Measured: Baseline and 6 months
Change in marginal bone level (MBL)
Marginal bone level will be measured compared to baseline. Participants' standardized radiographs will be used to determine bone level changes between baseline and 6 months.
Measured: Baseline and 6 months

Questions about this trial
What is this clinical trial studying?
An observational study of Peri-Implantitis, run by University of Michigan at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Change in Periodontal Probing Depths (PD) (time frame: Baseline and 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04251793, which also lists 16 linked publications.
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 12 Nov 2024.
