Abstract

Aim: The aim of this study was to measure the effect of different attachments: telescopic crown, double Akers’ (DA)clasp, distal clasp (DC)-retained removable partial dentures (RPDs), and cantilever bridge on the intrusive movement of the abutment teeth. Materials and methods: A model imitating mandibular ridge of Kennedy Class I was fabricated with first and second premolar as abutments. A telescopic crown, DA, DC-retained RPDs, and cantilever bridge were fabricated. Each partial denture was placed at a time on the model; 50 N force was applied on each partial denture using ZWICK universal testing machine. The intrusion of the abutments was recorded using SOLARTON device. Data were collected and tabulated. Results: The mean values of the intrusive movement in telescopic separated (TS) RPD, telescopic joined (TJ) RPD, DA RPD, DC RPD, and cantilever bridge in tooth 35 were 147, 75, 57, 334, and 307 μm respectively, and in tooth 45 were 136,81, 65, 435, and 335 μm respectively. Conclusion: It can be concluded from the retrieved data that DA clasp-retained RPD caused less intrusion of the abutments than telescopic crown-retained RPD, followed by the DC than cantilever bridge. Clinical significance: The DA clasp is most favorable in the utilization in mandibular Kennedy Class I situation followed by telescopic crowns.
