<p>We perform the comparative analysis of the areas of external surfaces of dental implants containing both threads and annular grooves of different profiles. It is shown that, for implants with threads and grooves with the same triangular profiles, the surface areas of one- and two-way threads exceed the surface areas with annular grooves by 0.05% and 0.1%, respectively. According to the results of calculations, the surface area primarily depends on the pitch and height of the groove profile. Thus, the smaller the pitch and the larger the height of the profile, the larger the surface area. The comparison of the surface areas of implants with groove profiles of similar shapes demonstrates that, for the same outer diameters, the surfaces containing small grooves have larger surface areas than the surfaces with large grooves. For the same outer and inner diameters and the same pitch, the surfaces with grooves of rounded profiles and the surfaces with grooves of rectangular profiles have the surface areas larger than the surfaces with grooves of triangular profiles by 10.2 ± 5.7 % and 30.5 ± 10.6% on the average, respectively.</p>

摘要

We perform the comparative analysis of the areas of external surfaces of dental implants containing both threads and annular grooves of different profiles. It is shown that, for implants with threads and grooves with the same triangular profiles, the surface areas of one- and two-way threads exceed the surface areas with annular grooves by 0.05% and 0.1%, respectively. According to the results of calculations, the surface area primarily depends on the pitch and height of the groove profile. Thus, the smaller the pitch and the larger the height of the profile, the larger the surface area. The comparison of the surface areas of implants with groove profiles of similar shapes demonstrates that, for the same outer diameters, the surfaces containing small grooves have larger surface areas than the surfaces with large grooves. For the same outer and inner diameters and the same pitch, the surfaces with grooves of rounded profiles and the surfaces with grooves of rectangular profiles have the surface areas larger than the surfaces with grooves of triangular profiles by 10.2 ± 5.7 % and 30.5 ± 10.6% on the average, respectively.
