Purpose: The aim of our study is to examine whether there is a difference between the internal compatibility of metal-ceramic restorations produced by the methods of casting, milling, DMLS (Direct Metal Laser Sintering) and LaserCusing.®Tools and Methods: For the purpose of evaluating internal conformity, 48 prepared premols and molar teeth are modeled on a bronze metal basis.The 12 pieces of metal infrastructure produced by the methods of casting, milling, DMLS and LaserCusing were simulated on the metal dots after the application of porselen.®The samples taken in the acrylic pattern after simulation were freezed to the middle line in the bukkolingual direction.Subsequently, under a stereomicroscope, the internal range values were recorded by making 30 measurements on each backdrop tooth. The analysis of internal interval data was statistically evaluated by one-way variance analysis (p<0.05).Results: The lowest average internal range values were observed in restorations produced using the LaserCusing method and statistically significant differences were found between all other methods (p<0.05).®Result:The study found that the LaserCusing method was more successful in terms of internal conformity of restorations than the casting, milling and DMLS methods.®
