About this study

Official title: Non Surgical Protocol for Treatment of Mucositis Using an Er:YAG Laser or an Air-abrasive Device: a Randomized Clinical Trial

Peri-implant mucositis is an important disease entity as a result of its high prevalence and the lack of a standard mode of therapy.

Non-surgical therapy of peri-implant mucositis appears to be partially effective in resolving the disease. In several cases, however, only limited improvements have been reported in the main clinical parameters (bleeding partial resolution and presence of pocket at follow-up visits) and there is a clear tendency to relapse of the disease.

In these cases it is therefore recommended to consider adjunctive therapies. Numerous approaches have been used for implant surface decontamination including mechanical, chemical and treatments by means of air-powder or laser.

The aim of the present randomized controlled clinical trial will be to assess the efficacy in improving clinical parameters of two further methods of implant surface decontamination (Er:YAG laser or air-abrasive device) after mechanical cleaning during non surgical treatment of peri-implant mucositis.

Read the detailed description

Peri-implant mucositis, defined as an inflammatory lesion of the surrounding peri-implant tissues without loss of supporting bone, is an important disease entity as a result of its high prevalence and the lack of a standard mode of therapy. Although the current epidemiological data are limited, peri-implant mucositis affects 43% of the subjects.

Numerous approaches have been used for implant surface decontamination, including mechanical, chemical and laser treatments. Using conventional mechanical means, eradication of pathogens on implant surfaces with threads and often with rough surface structures is difficult. Treatment models, such as debridement, effectively used to treat teeth with periodontitis, cannot be used in the same way on rough threaded implant surfaces. The implant rough surface structure also provides the bacteria with ''protected areas'', inaccessible to conventional mechanical removal.

A treatment protocol that may offer an advantage over traditional mechanical treatment includes the use of laser therapy. Data have shown that treatments with Er:YAG lasers have a bactericidal effect. Er:YAG laser treatment can debride the implant surface effectively and safely. Slightly better clinical results in terms of bleeding on probing and clinical attachment level have been reported by Er:YAG laser treatment as compared with traditional non-surgical mechanical debridement with curettes and chlorhexidine.

The air abrasive method for the removal of bacterial plaque on tooth surfaces has also been used in the treatment of mucositis, demonstrating no relevant adverse effects. Until recently, air-polishing devices have used a slurry of water and sodium bicarbonate (NaHCO3) and pressurized air/water. A less abrasive method using an aminoacid glycine has been proven to be effective in removing bacterial biofilm structures in deep periodontal pockets and safe by not causing emphysema. Moreover the use of a glycine-based powder does not seem to cause titanium implant surface changes.

The aim of the present randomized controlled clinical trial will be to assess the efficacy in improving clinical parameters of two further methods of implant surface decontamination (Er:YAG laser or air-abrasive device) after mechanical cleaning during non surgical treatment of mucositis.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Mechanical debridement with curettesProcedure or surgery

    mechanical debridement: Inflammatory tissue, excess cement or plaque deposits will be removed using hand instruments

  • Er:YAG laserProcedure or surgery

    mechanical debridement: Inflammatory tissue, excess cement or plaque deposits will be removed using hand instruments. Furthermore, an Er:YAG laser will be used for the implant surface decontamination.

  • Air PowderProcedure or surgery

    mechanical debridement: Inflammatory tissue, excess cement or plaque deposits will be removed using hand instruments. Furthermore, an Air-Powder treatment will be provided on the implant/abutment surface.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Bleeding on probing changes

    changes of bleeding on probing, evaluated as present if bleeding will be evident within 30 s after probing, or absent, if no bleeding will be noticed within 30 s after probing

    Measured: baseline, 1, 3, 6 months

Secondary outcomes (4)
  1. probing pocket depth changes

    changes in probing pocket depth, measured from the mucosal margin to the bottom of the probable pocket

    Measured: baseline, 1, 3, 6 months

  2. mucosal recession changes

    changes in mucosal recession, measured from the mucosal margin to the restoration margin or implant neck

    Measured: baseline, 1, 3, 6 months

  3. clinical attachment level changes

    changes in clinical attachment level, measured from the restoration margin or implant neck to the bottom of the probable pocket at six aspects per implant (mesio-vestibular, mid-vestibular, disto-vestibular, mesio-oral, mid-oral, and disto-oral.

    Measured: baseline, 1, 3, 6 months

  4. complete disease resolution (percentage)

    At the implant level, the level of disease resolution was defined as complete when BoP was = 0 out of six sites per implant

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing Mechanical debridement with curettes, Er:YAG laser and Air Powder in people with Peri-implant Mucositis, run by Università Vita-Salute San Raffaele at 1 site in Italy.

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 4 inclusion and 9 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 3 Mar 2023. 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 Italy. 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. Some participants in this study may receive a placebo. 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?

Bleeding on probing changes (time frame: baseline, 1, 3, 6 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 3 Mar 2023.
