Abstract

Purpose: This study evaluated the marginal adaptation and microleakage of the In-Ceram Alumina, In-Ceram Zirconia and Finesse press all-ceramic porcelain systems. Material and methods: Thirty maxillary central teeth extracted for periodontal reasons without caries and cracks were divided equally into three groups and there was no control group; only the three systems were compared. Sample teeth cemented were stored in distile water for 24 hours. Then, they were applied to a repeated thermal cycle for 500 times. The samples were left in 5% of basic fuchsin dye for 24 hours. For the marginal adaptation rankings, all of the sample teeth for which cross-sections were made were moved into the metal microscope (Scherr Turico St. James/Minn./USA) and the marginal adaptation degrees were measured in both the palatinal and vestibul regions by measuring twice with x10 enlargement at micron level. For the statistical evaluations of marginal adaptation and microleakage values, Kruskal Wallis test has been used. Results: The differences between the three all-ceramic porcelain systems are not significant. The Finesse porcelain system caused the least leakage in both regions. In second place in both regions was In-Ceram Alumina. In-Ceram Zirconia caused the most leakage in bothregions. The biggest magrin gap in the palatal region was seen in the Finesse porcelain system, In-Ceram Zirconia in second place. Theleast marginal gap was caused by the In- Ceram Alumina porcelain system. Conclusions: When the microleakage scores of the In-Ceram Alumina, In-Cream Zirconia and Finesse groups are compared, the differences between the groups are not significant. When the marginal adaptation values of the In-Ceram Alumina, In-Ceram Zirconia and Finesse groups are compared in terms of palatal and vestibular values, the differences are not statistically significant.
