“…When a fixed prosthesis is supported by implants, the average maximum occlusal force acting on the first premolar and molars is reported to be approximately 200 N. 34 A previous in vivo study demonstrated that the direction of the occlusal load is approximately vertical for implants in the lower first molar region. 35 Therefore, a vertical load of 200 N was applied to the right terminal of the framework in all models (cantilever loading).…”

“…Mericske-Stern et al (25) reported maximum occlusal force of 206.1±87.6 N for the first premolars, 209.8±88.2 N for molars, and 293.2±98.3 N for second premolars in patients wearing implant-supported partial fixed prostheses. Strain gauge studies in implantology generally use low loads varying from 20 to 300 N (8)(9)(10)(11)13,22) and other works used custom-built load-application devices (8)(9)(10)(11).…”

Load-Application Devices: A Comparative Strain Gauge Analysis

In view of the low loading values commonly employed in dentistry, a load-application device (LAD) was developed as option to the universal testing machine (UTM), using strain gauge analysis. The aim of this study was to develop a load-application device (LAD) and compare the LAD with the UTM apparatus under axial and non-axial loads. An external hexagonal implant was inserted into a polyurethane block and one EsthetiCone abutment was connected to the implant. A plastic prosthetic cylinder was screwed onto the abutment and a conical pattern crown was fabricated using acrylic resin. An impression was made and ten identical standard acrylic resin patterns were obtained from the crown impression, which were cast in nickel-chromium alloy (n=10). Four strain gauges were bonded diametrically around the implant. The specimens were subjected to central (C) and lateral (L) axial loads of 30 kgf, on both devices:

Purpose: The aim of the present study was to use finite elemental analysis (FEA) to evaluate bone stress near an implant placed at the border between the mandible and fibular graft in mandibular reconstruction. Materials and Methods: A fibular model (FM) and transplantation model (TM) were constructed for FEA. In TM, mandible was on the mesial side and the fibular graft was on the distal side. The implant was positioned at the center of both bone models. In TM, it was placed on the border between the mandible and fibular graft. A 10-mm implant was used in the monocortical model and a 15-mm implant was used in the bicortical model. The loading force was set at 100 N, the angle was set at 90˚, and the loading position was set as center, mesial, or distal on the upper surface of the prosthesis. Von Mises equivalent stress values of the bone near the implant collar and apex at the middle line between buccal and lingual side were measured. Results: In all models, stress values were significantly lower with center loading than with distal loading and mesial loading. In center loading, the stress values were significantly lower in the bicortical model than in the monocortical model. There were no significant differences in stress values between FM and TM in all conditions. Conclusions: Bone stress was least with the center loading position, which was further decreased by bicortical fixation. There was no increase in mechanical stress associated with placing an implant at the border between the mandible and the fibular graft.
