A technique is presented in which acrylic resin extensions from the labial surface of the anterior tissue base of a Kennedy Class IV removable partial denture are used as retentive elements to minimize motion around the axis of rotation. The labial rests, formed by extending the base material of the prosthesis onto the mesiobuccal surfaces of the anterior abutments, act as guiding planes, preventing rotation of the prosthesis. The rests also improve esthetics by covering the interdental spaces often found between the prosthesis and the abutment teeth. The technique has been used successfully with 26 patients over a 3-year period.
本文介绍了一种技术，即在肯氏IV类可摘局部义齿前牙组织基托唇面制作丙烯酸树脂延伸部分，将其用作固位元件，以最大程度减少围绕旋转轴的移动。通过将修复体的基托材料延伸至前基牙的近中颊面形成唇侧支托，该唇侧支托起到导平面的作用，防止修复体旋转。支托还通过覆盖修复体与基牙之间常见的牙间隙来改善美观。在3年期间，该技术已成功应用于26例患者。
