Patients will be randomly divided into two groups:

Erythritol group: erythritol with a particle size of ~14 µm will be used for 5 seconds (AIRFLOW® PLUS EMS) Ultrasonic scaler group: a piezoelectric handpiece with peek inserts (Mini Piezon EMS; PI EMS) .
Different subgroups will be defined according to the material of the dental crown of the related implant.
The mechanical debridement appointments will be carried out at the baseline, after 6 months, and after 12 months, after instruction and motivation of the patient, completion of the clinical chart with the recording of the Probing Depth (evaluation in mm of the peri-implant sulcus taken by a periodontal probe; 4 surfaces of the gingival margin are detected: vestibular, palatal/lingual, mesial, distal), Bleeding on Probing and Plaque Control Record.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Probing Depth (PD)
Evaluation in mm of the peri-implant sulcus taken by a periodontal probe. 4 surfaces of the gingival margin are detected: vestibular, palatal/lingual, mesial, distal.
Measured: Baseline (T0), 6 months (T1), 12 months (T2)
Change in Bleeding on Probing (BoP)
Evaluation of the presence or absence of gingival bleeding during a probing with a dichotomous scoring (yes/no) of bleeding sites. The sum of the bleeding sites is divided for the total sites and multiplied per 100.
Measured: Baseline (T0), 6 months (T1), 12 months (T2)
Change in Plaque Control Record
% assessment of the amount of plaque on dental surfaces; it is detected on 4 surfaces: distal, mesial, vestibular, lingual / palatal. The number of sites with plaque is divided by the total number of sites available in the mouth and multiplied by 100. Results indicate the index as a percentage.
Measured: Baseline (T0), 6 months (T1), 12 months (T2)

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The aim of the study is to assess the effect of a 12-month peri-implant protocol with erythritol orultrasonic scaler with peek inserts for dental implants with crowns made by different materials .
Patients will be randomly divided into two groups:
Erythritol group: erythritol with a particle size of ~14 µm will be used for 5 seconds (AIRFLOW® PLUS EMS) Ultrasonic scaler group: a piezoelectric handpiece with peek inserts (Mini Piezon EMS; PI EMS) .
Different subgroups will be defined according to the material of the dental crown of the related implant.
The mechanical debridement appointments will be carried out at the baseline, after 6 months, and after 12 months, after instruction and motivation of the patient, completion of the clinical chart with the recording of the Probing Depth (evaluation in mm of the peri-implant sulcus taken by a periodontal probe; 4 surfaces of the gingival margin are detected: vestibular, palatal/lingual, mesial, distal), Bleeding on Probing and Plaque Control Record.

Questions about this trial
What is this clinical trial studying?
A study testing Erythritol prophylactic powders and Ultrasonic scaler with peek inserts in people with Peri-implant Mucositis, run by University of Pavia 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 3 inclusion and 4 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 8 Apr 2025. 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. 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 Probing Depth (PD) (time frame: Baseline (T0), 6 months (T1), 12 months (T2)). The study lists 3 primary outcomes in all. 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 8 Apr 2025.
