The main goal of this study was to understand the effects of insertion forces on the wear properties of dental implants. It is hypothesized in this study that titanium dental implants may be subjected to wear during implantation, which can result in particle generation and accumulation in the surrounding tissues. Metal particle accumulation may contribute to adverse tissue reaction and diseases like peri‐implantitis. To quantify particle generation upon implant insertion, 4 dental implants (Straumann USA LLC, 10 mm) were inserted in sawbone blocks of increasing densities, 10 PCF, 20 PCF, 30 PCF, and 40 PCF (pounds per cubic feet, PCF), simulating implantation in the bone. After insertion, each implant was removed from the block, which were sectioned for microscopic inspection. The internal surface of the sectioned blocks, the surface of the implants, and the compositions of the particles were analyzed with 3D microscopy (Keyence, VHX200), Scanning Electron Microscopy (JEOL 5600), and powder X‐ray (Bruker D8 Advance). 3D microscopy and Scanning Electron Microscopy revealed the presence of metal debris deposited in each density of sawbone . The amount of particles deposited was observed to decrease with increasing sawbone density. Powder X‐Ray Diffraction confirmed that particles generated were mainly composed of titanium. Therefore, this study illustrates how the insertion of dental implants may lead to the generation of metal particles in the encompassing tissue. This suggests that deformation of the implant surface and particle accumulation may start to develop in stages as early as insertion.
