Biofilm removal from implants supported restoration using different instruments: a 6-month comparative multicenter...

Area of Science:

• Dental Implantology
• Periodontology
• Biomaterials Science

Background:

• Peri-implant mucositis is a prevalent inflammatory condition affecting implant-supported restorations.
• Effective biofilm removal is crucial for managing peri-implant diseases and maintaining implant health.

Purpose of the Study:

• To compare the efficacy of four different instruments in removing biofilm from implant-supported restorations.
• To evaluate the impact of various non-surgical therapeutic approaches on peri-implant inflammation.

Main Methods:

• A comparative multicenter clinical study involving 89 patients with peri-implant mucositis.
• Treatment groups utilized ultrasonic scalers (plastic tips), titanium curettes, airflow with glycine powder, or rubber cup with polishing paste.
• Clinical parameters including modified Plaque Index (mPI), modified Bleeding Index (mBI), probing depth (PD), and recession (REC) were assessed over six months.

Main Results:

• No significant differences in the reduction of peri-implant mucosal inflammation were observed among the four treatment groups immediately after therapy.
• All tested non-surgical therapies demonstrated effectiveness in reducing peri-implant mucositis.
• Sonic scaler with a plastic tip and rubber cup with polishing paste showed a trend towards higher efficacy in biofilm removal.

Conclusions:

• Non-surgical therapy is a viable and effective treatment for peri-implant mucositis.
• Ultrasonic scalers with plastic tips and rubber cups with polishing paste may offer superior outcomes for biofilm removal in managing peri-implant conditions.
• Further research could explore long-term efficacy and patient-reported outcomes for different instrumentations.
