A variety of studies have shown the relationship between peri-implantitis and functionally relevant polymorphisms in the genes of cytokines IL-1A, IL-1B, IL-RN and TNFA.
Using genetic testing allows for the allocation of a certain degree of inflammation to the detected combination of alleles.
Patients with degree 3-4 are considered high responders and are thus risk patients for titanium associated inflammatory processes/ loss of implant.
