In this study, the biomechanical properties of glass ionomer cement used for repair of incudostapedial joint bridge in ear in two different distances was investigated. A master block was used to locate the incus and stapes with a 91 degree angle constant. Two experimental groups were composed according to the distances between incus and stapes which were adjusted as 1.0 and 2.0 mm. The mixture of bone cement was applied to the gap between incus and stapes and adhere them together. Compression tests were performed to these joints. Strength value of group 1 were found significantly higher than group 2 (p=0.042). The fragility of bone cement used in 2 mm gap was 25,5% higher compared to 1 mm gap
