Abstract
This study was performed to investigate the effects of impression method and design of the retainer on the stress of abutment tooth in distal extension RPD. Three different types of direct retainer such as Akers clasp. RPI clasp, and wrought wire clasp were designed . Stress on the abutment tooth was measured and analyzed with strain gauge method. Impressions were anatomic impression technique and functional impression technique. The following conclusions were drawn from this syudy. 1.The stress at the abutment tooth on all RPD was decreased in functional impression except RPI clasp retained RPD. 2.The stress at the abutment tooth on RPI clasp retained RPD was the most smallest in anatomic impression 3.While load is increase the stress at the abutment tooth was increased, but the change of stress at the buccal side of abutment tooth was not too much in functional impression.
