Air Polishing Effective Strategy to Maintain or Improve Outcomes of Surgical Therapy for Peri-Implantitis
Air Polishing Effective Strategy to Maintain or Improve Outcomes of Surgical Therapy for Peri-Implantitis suggests a new study published in the Clinical Oral Implants Research
The aim of the present study was to evaluate the efficacy of a supportive peri-implant care (SPIC) protocol after surgical therapy of peri-implantitis, combining ultrasonic mechanical debridement and glycine powder air polishing.
Thirty subjects diagnosed with peri-implantitis and treated by means of access flap were randomized 6 months later into two different SPIC groups: the test group combined a piezoelectric ultrasonic instrumentation with a specific implant PEEK tip and glycine powder air polishing, while control group received the same ultrasonic instrumentation together with a rubber cup and a polishing paste. Patients were followed for 12 months, with intermediate SPIC visits every 3 months. Clinical, radiological, microbiological and biochemical outcome variables were registered and calculated.
Results
After 12 months of SPIC, probing depths (PD) showed a mean reduction of 0.33 ± 0.11 mm, with significant differences (p < .001) between the test (−0.84 ± 0.43 mm) and the control group (+0.18 ± 0.73 mm). Healthy peri-implant tissues defined by PD <5 mm, absence of BoP (or in only one site around the implant), and no additional bone loss (<0.5 mm), were observed at the final visit in 83% of the implants (87% in the test group and 80% in the control group, p = .255). No adverse events were reported by the subjects participating in the study.
The SPIC protocol including mechanical ultrasonic debridement and glycine powder air-polishing demonstrated significantly better efficacy in terms of PD reductions. A strict SPIC protocol can maintain for 1 year, or even improve, the results obtained after surgical treatment of peri-implantitis.
