Abstract:

Purpose: The purpose of this study is to compare the values of the direct metal laser synthesis (DMLS) and the power of repair after the different surface processes of the infrastructures obtained through casting. Tool and Method: Examples in the form of disc were prepared with 48 drops and 48 DMLS methods from the Kobalt-Chrome alloy. Half of the casting and DMLS samples were divided into three subgroups for surface processes to be performed after the application of untouched porselen: Al2O3 grinding (C); acidization and Al2O3 grinding combination (A); silicone cutting (S). After the agents in the porselen repair kit were applied to all sample surfaces, a nano-hybrid composite resin was condensed to the middle parts. Cutting connection resistance was recorded with a universal test device. The results were analyzed statistically (α=0,05). Results: Examples obtained by conventional casting method observed higher connectivity values (p<0,05) than the samples obtained by DMLS. In the groups in which the repair connection increased with silicone coating and acidization and the coating combination with Al2O3 particles, higher connectivity values were observed compared to the groups in which the coating with Al2O3 particles was applied (p<,05). The result: The study found that laser synthesis and casting metal infrastructures showed different connectivity values.
