STUDY OF THE IMPACT OF INCREMENTAL TECHNOLOGY ON MECHANICAL AND TRIBOLOGICAL PROPERTIES OF BIOMATERIALS
Journal Title: Tribologia - Year 2017, Vol 273, Issue 3
Abstract
The latest method for creating denture replenishment in CAD / CAM systems is Direct Metal Laser Sintering (DMLS) technology. With the use of DMLS, prosthodontics, implant prosthetics, and facial-cranialjaw surgery adapted to individual patient conditions can be realized. The aim is to evaluate the strength, microstructure, and tribological properties of Ti6Al4V and CoCrMo alloys obtained from DMLS technology in the aspect of therapeutic constructions. The conducted tests show that, in the DMLS technology, as compared to milling technology preceded by casting and forging or pressed powder and sintering, for the same percentage composition of elements, the micromechanical properties, microstructural and tribological change. This procedure, from which constructions for various dental applications are obtained, is the new technology preferred for making permanent restorations faced with ceramics, producing intravascular implants, and implants of the temporomandibular joint. It can be an alternative to conventional cast-based methods and CAD / CAM based milling.
