The pathogenesis of periimplantitis is multifactorial. Professor Dr. Stefan Renvert, University of Kristianstad/Sweden, outline in this fourth part of his lecture series (held on the EDA Early Dental Workshop) the risk factors, that promote the development of periimplantitis. The domestic oral hygiene plays an important role in this.
Therefore the dentist has a great responsibility, especially in patients that already suffered from periodontal problems: He has to instruct these patients in cleaning the periimplant tissue most properly and has to integrate them in an individually shaped recall programm. Besides the oral hygiene risk factors for periimplantitis are regular tobacco consumption, imbalanced nutrition, alcohol abuse and psychosocial distress. Genetics also are an issue.
The gingival biotype has to be listed here, too. A small volume of keratinized gingiva often involves an increased plaque accumulation and therefore an increased tendency for tissue inflammation, recessions and loss of attachment. So this is another important risk factor in the genesis of periimplantitis.
