ABSTRACT The poor soft tissue integration around titanium implants creates a microgap that serves as a pathway for pathogen invasion, resulting in infection, inflammation, and the progression of peri‐implantitis. As the implant’s transmucosal component, the abutment determines the degree of peri‐implant soft tissue attachment.

Tracking with GPS and accelerometers shows that great evening bats in subtropical China use two overwintering strategies: some remain in continuous hibernation, while others switch between torpor and activity as temperatures change. This behavioral flexibility, shaped by climate, underscores the importance of protecting diverse roosting habitats for ...
