Tribological behaviour of unveneered and veneered lithium disilicate dental material

“Digitally Oriented Materials”: Focus on Lithium Disilicate Ceramics

“…Friction and wear effects of lithium disilicate on the opposing natural tooth enamel have been also investigated, with and without fluorapatite coating, showing that they were less severe in unveneered specimens [37]. The initial surface roughness did not influence the final wear but the topography of the wear pattern affected the corresponding wear loss, since a smoother final wear aspect was associated with lower wear.…”

Wear resistance and abrasiveness of CAD-CAM monolithic materials

“…Therefore, the wear resistance and abrasiveness of these materials is important. The wear properties of zirconia, [3][4][5][6][7][8] lithium disilicate, 3,4,6,9,10,11 zirconia-reinforced lithium silicate, 10 polymer-infiltrated ceramic, and nanofilled composite resin 6,10,12 when opposed to enamel have been reported. However, the multifactorial nature of wear 6,13,14 makes it important to understand the wear potential of the materials based on the composition and microstructural aspects [15][16][17] that will determine their properties.…”

Two simple methods for surface modification of lithium disilicate dental blocks with hydroxyapatite

“…As it is known from the literature, the Ca/P ratio of HA is 1.67 and it is the same as the value obtained in this method [17,18]. It was determined that the Na, Si, and K elements of the 102 EDS results from the blocks which used as substrate material [2], Al element was determined due to the blasting process applied before the coating. The high crystallinity of the HA shows that it will not dissolve easily and have a long life in the physiological environment.…”

“…Crowns are prepared according to the model. If porcelain is used, the natural tooth tone is determined and the support adheres to the tooth [2]. Ceramic dental materials used in CAD/CAM processes are classified according to their chemical content; feldspathic, low leucite-containing glass, lithium disilicate and mica reinforced, alumina and magnesium ceramics.…”
