Aim:
To investigate the role of local factors and the association with peri-implantitis and peri-implant soft-tissue dehiscence (PISTD).
Materials And Methods:
A randomly selected sample of Norwegian patients who underwent implant therapy in 2014 was examined (242 patients; 732 implants). Clinical and radiographic parameters were recorded, including soft-tissue phenotype, mucosal margin mobility, connection type, platform switching, emergence angle, implant location and presence of adjacent teeth. To account for clustering of implants within patients, mixed-effects logistic regression models were applied.
Results:
Mucosal margin mobility, bone-level implants without platform switching, emergence angle > 45°, anterior implant location and daily smoking were identified as significant risk indicators for peri-implantitis. Thin soft-tissue phenotype, mucosal margin mobility, absence of adjacent teeth, peri-implantitis and external connection were detected as significant indicators for PISTD. Peri-implantitis and PISTD were present in 8.7% and 25.0% of implants, respectively.
Conclusions:
Local factors and soft-tissue-related parameters, many modifiable during treatment planning, were associated with peri-implantitis and PISTD. Particular attention should be given to soft-tissue phenotype, connection design, platform switching and prosthetic emergence angle. The relationship between systemic and local risk factors should be further investigated.
