In Vitro Micro-CT Assessment of a Novel Implant–Abutment Connection Under Static and Cyclic Loading

Applied Sciences
The implant–abutment connection (IAC) is a critical determinant of the mechanical and biological performance of dental implants. Connection design and insertion torque may influence fatigue resistance, micromovement, and microgap formation, thereby ...
