Pulverstrahlverfahren bei Periimplantitis – eine Pilotstudie

Das niedrig abrasive Pulverstrahlverfahren (Glycin 99%, Silizium 1%) zeigte in dieser Pilotstudie eine effektivere Verringerung der Sondierungstiefen nach 6 Monaten als lediglich eine manuelle Reinigung. Um diese Ergebnisse konfirmatorisch zu validieren fordert die durchgeführte Fallzahlplanung unter Berücksichtigung der Einschlusskriterien eine hohe Probandenzahl. Diese kann nur durch weitere Studienzentren erreicht werden.

In the investigated patient cohort, treatment with low abrasive powder stream (glycine 99%, silizium 1%) showed a more effective reduction of probing depths than mechanical debridement with plastic curettes after 6 months. The consideration of our strict inclusion criteria in the sample size calculation results in a large number of study participants which motivate the extension of our clinical trial to other study centers.
