Abstract

It was found that the fixation and stability of fixed prostheses on implants are interrelated with the degree of inclination of the walls of the supporting abutments. Using mathematical analysis, the dependence of the angle of inclination of the abutment wall on its height was determined in order to achieve optimal passive packing, a theoretical justification of the stability of the crown from tipping was carried out depending on the angle of inclination of the abutment walls, their transverse width at the base and height.

Key words:

dental implantation, passive packing of a non-removable prosthesis, angle of inclination of the walls of the abutment, fixation and stability of non-removable prostheses
