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.

| Measure | Description | Time Frame |
|---|---|---|
| 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. | 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. | 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. | Baseline (T0), 6 months (T1), 12 months (T2) |
