抄録

The wearing a removable partial denture may cause problems in oral tissues. Some of these problems can be solved by an appropriate distribution of functional forces on the abutment teeth and residual ridges. It is widely recognized that the concept of "rigid support" is effective for proper force distribution. This concept refers to the connection of rigidity in retainers and sufficient support on the residual ridges. The selection of suitable retainers is important for optimum force distribution. The cone-telescopic crown is generally accepted as being the retainer with the greatest connecting rigidity. The purpose of this study was to investigate the characteristics of stress distribution and vertical dislodgement of the denture base of four partial denture designs with cone-telescopic crowns.<BR>The results were as follows:<BR>1. The load distribution under the base of the cone-telescopic crown denture, which has two direct retainers and cross-arch stabilization (=design M1), was the smallest of the four partial denture designs.<BR>2. The apical stress on primary abutment teeth of the cone-telescopic crown denture, which has two direct retainers, was very large.<BR>3. The vertical displacement of the denture base of design M1 was the smallest of the four partial denture designs.
