Flexural properties of leucite and lithium disilicate ceramic materials after repeated firings

Endocrown restorations: Influence of dental remnant and restorative material on stress distribution

“…Leucite-reinforced glass-ceramic has been evaluated as an alternative to lithium disilicate for endocrown restorations and presented bonding strength to dentin similar to that of lithium disilicate [25], but with lower mechanical strength [26]. Fig.…”

Flexural strength comparison of self-synthesised porcelain with the sintering temperature of 1150 degree Celsius and 1200 degree Celsius

“…With the initial load and the speed of adding a more significant load will cause the fractured sample to be faster and the measurement results to be able because the force borne by the specimen becomes a dynamic force. 1,2,8,9 Differences of the flexural strength at 2 different combustion temperatures can be caused by the level of maturity associated with crystalline formation and porosity on porcelain. Crystalline formed on this self-synthesis porcelain was crystalline leucite.…”

“…In order to obtain porcelain with better mechanical properties, the time and temperature of sintering of self-synthesis porcelain must be readjusted. [2][3][4]…”

“…1,2 Occlusal forces associated with the masticatory forces of the posterior region range from 700-760 N which means dental porcelain with a thickness of 1-2 mm must have a flexural strength of 100-120 MPa in the occlusal area of the posterior teeth. [1][2][3] Flexural strength can be tested in various ways including three-point bending, four-point bending, or biaxial flexural strength test. 1,2 Felspathic porcelain has flexural strength between 60-80 MPa.…”

“…[1][2][3] Flexural strength can be tested in various ways including three-point bending, four-point bending, or biaxial flexural strength test. 1,2 Felspathic porcelain has flexural strength between 60-80 MPa. This material has a lower strength than the material used for all-ceramic, this is because felspathic porcelain is usually supported by metals in metal-ceramic restorations.…”
