Introduction and Purpose: The aim of this study is to assess the effect of the short-term thermal aging process on the feldspatic and lithium disilicate CAD/CAM seramics of self-adjective resin simans. Method and Requirements: 80 ceramic samples of 1.5 mm thickness were obtained from Vita Mark II (VIT) and IPS e.max CAD (MAX) blocks to be used in the study and MAX ceramic disks were synthesized. All samples were diluted with 5% hydrofloric acid and applied to the surfaces. Ceramic samples were divided into two groups and attached to them with the help of 3 mm diameter and 2 mm height plastic pipes Panavia SA (PSA) and RelyX U200 (RXU) self-adjective resin shells. The samples attached to the rectum were divided into two subgroups, and half of the samples were subjected to the thermal aging process in the thermal cycle device set to 5,000 wheels equal to the stay in the bathroom between 5-55°C temperature changes 30 s, transfer time 10 s, which is 10 s. After the aging process, all samples were tested at a speed of 0.5 mm/s with a Universal test device. The data obtained was assessed by the one-way ANOVA test (SPSS 23). The highest connectivity value between groups was measured in non-thermal aging VIT-PSA ceramics (10,50 ± 2,67 MPa), while the lowest values were measured in thermal aging applied MAX-RXU samples (6,81 ± 1,37 MPa) (p<0.01). There was no statistically significant reduction in the sliding strength values in the thermal aging process applied at 5,000 in the same groups (p>0.01). The thermal aging process in a short period of time did not cause a significant decline in the phosphatic and lithium disilicate values of self-adjective resin simans to CAD/CAM ceramics.
