Therapy of Peri-implantitis: Scaling Versus Low Abrasive Powder
Recruitment status was: Enrolling by invitation
In the last decade, the number of dental implantations continuously increases. However, at the same time, the prevalence of peri-implantitis increases, too. Although both surgical and non-surgical interventions are available for the therapy, there is no efficient and satisfying therapy option resulting in an adequate improvement of this disease.
An innovative, low abrasive powder has been introduced for the therapy of periodontitis. However, the powder might be suitable for the peri-implantitis therapy, also, and could improve the effectiveness of the therapy. The usage of this powder in peri-implantitis patients has not been assessed in a clinical trial although the effectiveness in natural teeth has been demonstrated.
The aim of this prospective, randomised, multi-centre trial is to assess the effectiveness of the aforementioned powder in peri-implantitis patients.

Primary Purpose: Treatment
|Official Title:||A Randomized Multicenter Study in the Therapy of Periimplantitis: Scaling Versus Low Abrasive Powder|
- Pocket probing depth [ Time Frame: Twelve months ]
- Assessment of pain levels [ Time Frame: One week and six months ]
- Assessment of the oral health related quality of life using the OHIP (14) [ Time Frame: One , three, six and twelve months ]
|Study Start Date:||January 2011|
|Estimated Study Completion Date:||January 2012|
|Estimated Primary Completion Date:||April 2011 (Final data collection date for primary outcome measure)|
|Experimental: Low-abrasive powder||
Procedure: Air abrasion of the implant surface with a low abrasive powder
Test treatment will be performed using the low abrasive powder in a standard air-polishing unit, which will be set up according to the manufacturer's instructions. The unit will be set to a medium water and powder setting, and the powder chamber will be filled to the indicated maximum powder level before treatment to ensure reproducible treatment conditions. The jet will be directed to the periodontal pocket for 5 s per surface (vestibular, lingual, mesio and distal) for subgingival plaque removal.
