[Clinical study of occlusal forces on dental implants].
The object of this investigation was to analyze occlusal force in patients applied an implant-supported prosthesis. The occlusal force was measured on four free end saddle patients applied 10 dental implants (F. E.) and two bounded saddle patients 4 dental implants. The pressure sensitive sheet and the image scanner (Dental Prescale 50H type R and Occluzer FPD 703, Fuji Photo Film Co.) were used. The occlusal force (O. F.) occurred in implanted portion was almost the same as that on a natural tooth. O. F. and O. F. bearing rate (B. R.) on the posterior dentitions applied implants tended to increase toward the distal side. The total O. F. had a tendency to increase after applying implant-supported prosthesis, and comparing implanted side with non-implanted (natural teeth) side, B. R. was equilibrium. On the other hand, occlusal contact areas, O. F. and B. R. were decreased at the most distal tooth of residual dentition on the implant side of F. E.
