N2 - Development, progression, and therapy of periimplantitis are nonresolved emerging problems. The aim of this pilot study was to establish a model for periimplantitis in mice to have a base for tests with immune-deficient knockout organisms to improve the knowledge about development and progression of periimplantitis and to develop further therapeutic options.In 8 mice, titanium implants were inserted in the median of the palate. Four of these implants had ligatures (periimplantitis group). After 2 weeks, the animals received a special diet enriched with sugar and flavor. After 9 weeks, micro-computed tomography (micro-CT) examinations to evaluate the periimplant tissue and histologies were performed.Dental implant insertions within the oral cavity are possible in living mice. Implants with ligatures showed significantly larger periimplant bone defects than controls. The radiologic findings were confirmed by histology. At the end of the observation period, the portion of implants lost was higher in the ligature group.This is the first publication to describe the insertion of dental implants in living mice. In addition, it is the first time that periimplant infection could be induced in that species. This model will pave the way to study knockout mice with reduced or even enhanced resistance to periimplantitis.
