Glass ceramics are subject to continuous improvement. Innovations and improvements in this area give hope for the development of the ideal all-ceramic restoration, which is strong, invisible and possible to adjust and polish in the conditions of each dental office, without having to return to the laboratory for additional glazing. The apparent smoothness of each structure is the basis of its clinical durability and prophylactic effect. It is important for the dentist to be aware of the condition of the surface after he made any corrections. Sometimes these corrections could lead to further com...
Glass ceramics are subject to continuous improvement. Innovations and improvements in this area give hope for the development of the ideal all-ceramic restoration, which is strong, invisible and possible to adjust and polish in the conditions of each dental office, without having to return to the laboratory for additional glazing. The apparent smoothness of each structure is the basis of its clinical durability and prophylactic effect. It is important for the dentist to be aware of the condition of the surface after he made any corrections. Sometimes these corrections could lead to further complications if no measures are taken. There is a difference in smoothness of the ceramic surface before and after clinical corrections. There are various protocols, including a set of different materials (burs, rubbers, felts, polishing pastes) and techniques for clinical polishing of different types of ceramic materials. The study aimed to investigate the changes in the parameters of surfaceroughness of test samples made of lithium disilicate press ceramics after different treatments.
