Özet:

The aim of the study is to evaluate the impact of metal primary, Nd: YAG laser and welding surface processes on the welding connection resistance between Co-Cr alloy surface and co-cover resin and acrylic artificial tooth materials. Methods and Requirements: The study used Co-Cr metal alloy (Magnum H60, Italy), two different coating resins (Sinfony and VisioCem, 3M ESPE, Germany) and two different artificial teeth (Acrylux, Italy and Ivoclar Vivadent AG, Liechtenstein). 240 Co-Cr samples were sanded with Al2O3. Examples were divided into 4 groups for resin and artificial tooth materials and 6 subgroups for surface processes (n=10). Groupe 1 has not been implemented surface processing (control). Other groups were subjected to different surface processes (Group 2: metal primer, Group 3: rocatec, Group 4: Nd: YAG laser, Group 5: Nd: YAG laser+rocatec and Group 6: Nd: YAG laser+metal primer). After completion with 2 different artificial teeth and 2 different coating resin, the connection resistance was assessed by the coating connection test. The highest connectivity values were seen in the laser+rocatec groups and the lowest values in the control groups. Different surface processes and different coating materials have been effective in linking the skeletal substructure to the refined upper structure (P<.001). Artificial tooth and coating grids do not show significant differences in relation to their connectivity (P>0.05). PROTECTION and RESULT: Applying different surface processes to the metal surface increases the measuring connection values. The application of rocatec or metal primary with laser and laser to the metal surface increases the connection resistance.
