Abstract

Purpose: Evaluation of the resistance to dislodging resistance in the conventional overdenture, mini-poll coping, and telescopic crown. Materials and methods: A sample size of 45 participants (15 in each group) was determined. Partially edentulous patients with only the two lower canines present were selected. After the fabrication of the three prostheses, using a force gauge, a dislodging pushing force was applied to the three groups at the labial frenal notches. Measurements were taken at insertion, after 1 and 3 months. One-way analysis of variance (ANOVA) and Tukey was calculated for the groups. Results: The mean values for the conventional overdenture, mini-poll, and telescopic at insertion were 2.45 ± 0.095, 6.47 ± 0.101, and 6.66 ± 0.239 newton (N), respectively. The mean values for the conventional overdenture, mini-poll, and telescopic after 1 month were 3.58 ± 0.13, 8.5 ± 0.5, and 7.80 ± 0.435 N, respectively. The mean values for the conventional overdenture, mini-poll, and telescopic after 3 months were 3.7 ± 0.147, 8.56 ± 0.598, and 8.56 ± 0.452 N, respectively. Conclusion: The mini-poll coping and telescopic crown recorded the highest retentive values, however, the mini-poll had the advantage of much lower cost when compared with the telescopic crown.
