Periointegration for safe implants

Prof. Dr. Marc L. Nevins

"The greatest challenge remains to guarantee the longterm lifetime of an implant. After the problem of osseointegration has been solved, now periointegration is at the focus of our efforts."
Prof. Dr. Marc L. Nevins

First breakthrough in dental implantology was in 1952, when the Swedish professor Mr Per-Ingvar Brånemark conducted the groundbreaking research on "osseointegration" of titanium in the human bone. In Germany, this method has been used for implants in the mouth, jaw and face area since 1969.

However, long-term durability of the dental implants still represents a problem in dental implantology: the rate of reported peri-implantar mucositis is above 50 %, and the rate of peri-implantitis is at 12 % to 40 % (Lindhe J, Meyle J, 2008). Correspondingly, it should be assumed that - within a time period of ten years - approximately one third of all implants will develop an inflammation of the surrounding tissue, possibly resulting in loss of the implant.

In 2006, the Academy of Periointegration (AP) was founded to counter this problem. This association of experts defined design-related and medical-technical improvements to ensure inflammation-free embedding of implants into the surrounding gingiva also on the long term. This new method of healthy and long-term tissue integration of dental implants has been denominated "periointegration" by the researchers.

Subsequently, a new type of dental implant - the "PerioType" implant - that provides the required "periointegrative" features was developed jointly with the Fraunhofer Institute.

Particular the use of a new type of high-tech zirconium nitride coating in the transgingival region shows a significantly improved biocompatibility and increased apposition of gingival fibroblasts as compared to pure titanium (Becker J, 2008). Thanks to the significantly increased surface hardness, even scalers and curettes do not impair the surface properties. Furthermore, recent scientific surveys show that zirconium nitride is less prone to apposition of plaque as compared to titanium. The composition of the bacteria is significantly less pathogenic (Grössner- Schreiber B, 2012).

When using the zirconium nitride surface, patented by Clinical House Europe, together with an extremly stable inner implant connection and an innovative sealing implant shoulder (SIS), which ensures a tightness of the implant comparable to a Swiss diver's watch, the implant systems made by Clinical House Europe combine both optimal osseointegration and perfect periointegration.

Periointegration + Osseointegration = 100% safe implants
