NIWOP – No Implantology Without Periodontology

PD Dr. Kristina Bertl, PhD MSc MBA

Unfortunately, both peri-implant mucositis and peri-implantitis are common biological complications around dental implants. Peri-implant mucositis and peri-implantitis are diagnosed in almost every second and fourth patient, respectively (Derks & Tomasi 2015).

To reduce the prevalence of these biological complications, the NIWOP approach by W&H aims to provide a reminder of the facts we actually already know. NIWOP steht für „No Implantology without Periodontology“ – a principle that no oral health professional should call into question. Nonetheless, we repeatedly see cases in daily clinical practice where this principle has unfortunately not been upheld in full. And it is precisely in this context that the NIWOP clinical workflow is intended to be applied and be helpful.

This workflow starts long before implantation itself and applies long after the prosthetic restoration has been fitted. It is divided into 3 areas/phases:

  1. Pretreatment and establishment of a healthy periodontal condition
  2. Implantation
  3. Aftercare/follow-up phase

Prophylaxis measures have a very important role to play in 2 of these 3 areas – in pretreatment and in the aftercare/follow-up phase.

The NIWOP approach will be explained in more detail in upcoming articles, especially the science behind it – and there will be a particular focus on the areas in which prophylaxis should be indispensable.
