The present study aimed to enhance the efficiency and efficacy of the Al/Cu joint production process implemented by the company VEMID Ltd., Jagodina, Serbia, by attaining sound joints within a very short welding time. For this purpose, the present study aimed at investigating the accuracy and the quality of the continuous drive friction welding (CDFW) process, as well as the optimum combination of CDFW parameters with highest joint efficiency in terms of investigated properties.

The aim was to investigate whether fiber-post placement had an influence on the fracture resistance of endodontically treated immature teeth.
Materials And Methods: To simulate immature teeth, the apical third of 20 intact mandibular premolars was resected.
