Diagnostics of periimplantitis is the topic of the second part of the lecture series of Professor Stefan Renvert, University of Kristianstad/Sweden, held on the EDA Early Dental Workshop. By mere clinical assessment of the periimplant soft tissue a periimplantitis is hard to differentiate from a periimplant mucositis. Both pathologies show flush and swelling of the gingiva, but only periimplantitis involve loss of the marginal bone.
Radiological examination of those most times crateriform bone loss is inevitable. Obligate too is the probing of the implants. Prof. Renvert advises the use of a plastic periodontal probe. Because of their flexibility they can be used even in region, which are difficult to access because of the superconstruction. It is most important to use the same probing product in the recall too, for this is the only way to achieve repeatable and therefore comparable probing depths.
