Subject to the limitations of this study, the use of any installation load greater than 0 N is recommended for the installation of ball and Locator attachments on a denture base.

Influence of female attachment installation load on movement and resultant forces in implant overdentures, Journal of Prosthodontics, Vol. The resultant force decreased with increasing installation load for all attachments.

In particular, the resultant force on implants on the loading side of the Locator attachment significantly decreased when the installation load was increased from 0 to 50 N, and that for magnetic attachment significantly decreased when the installation load was increased from 50 to N.

For the residual ridges on the loading side, the direction of the forces for all attachments changed to downward with increasing installation load. The two implants and bilateral molar ridges were connected to three-axis load-cell transducers, and a universal testing machine was used to apply a 50 N vertical force to each site of the occlusal table in the first molar region.

Furthermore, the yaw Euler angle increased with increasing installation load for the magnetic attachment. The denture movement was measured using a G 2 motion sensor. Three types of attachments, namely ball, Locator, and magnetic attachments were used.

Regarding magnetic attachments, our results also recommend installation on a denture base using any installation load greater than 0 N, and suggest that the resultant force acting on the implant can be decreased by increasing the installation load; however, a large installation load of N should be avoided when installing the attachment on the denture base to avoid increasing the denture movement.

Three installation conditions, namely, the application of 0, 50, and N loads were used to install each attachment on the denture base. An acrylic resin mandibular edentulous model with two implants placed in the bilateral canine regions and removable overdenture were prepared.

The load transfer and denture movement were then evaluated.1. 市川 哲雄, 渡邉 恵: 局部床義歯(部分床義歯)の支持,把持,維持の考え方, 年8月. 2. 市川 哲雄: 患者さんのエイジングに備える高齢者への歯周治療と口腔管理. 1. Introduction [2] The supply of freshwater that supports human health and enterprise is basically constant, representing only about 1% of the water available worldwide.

Good quality, nonsaline water is the global asset most important in satisfying the increasing demand for basic food, fiber, feed and fuels.
