Abstract
A screw for dental implants whose geometry was designed from nine parameters (diameter, length, body angle, pitch, coronal thread angle, apical thread angle, apical rounding, thread width and thread depth) that allow to calculate the distribution of its mechanical load. This geometry allows the distribution of efforts to optimize bone remodeling and improve osseointegration.
