To find the change of bone around the implants by year, we examined X-rays of the bone surrounding the implants (Oratronics: Standard and Generation-Ten) that had been installed in the mandibular molar region,and organized them into four basic classes. We examined dental X-rays of 367 cases of blade implants in the mandibular molar region. We found that the conditions of bone around the implants installed between teeth were better than those of the bone around the implants installed in the free-end portion.We also found that the conditions of the bone around the implants (Generation-Ten) were better than those of the bone around the implants (Standard).
