“…During the t-m transformation process, zirconia's stability can be enhanced by limiting crack extension through the expansion of the particle volume, which is limited by the surrounding material. This phenomenon is known as “stage transformation strengthening.” The flexural strength of partially stabilized zirconia is generally in the range of 1600-2100 MPa and a modulus of elasticity of approximately 200-210 MPa [ 56 ]. Zirconia ceramics have a very high mechanical strength at normal temperatures.…”

With the development of ceramic technology, prosthodontic ceramics are becoming a useful option for improving esthetic outcomes in dentistry. In this paper, various ceramic materials were reviewed and evaluated, and their advantages and disadvantages and indications in oral prosthodontics were analyzed objectively. The properties of resin-based ceramics, polycrystalline ceramics, and silicate ceramics were compared and analyzed. Resin-based ceramics may replace other ceramic materials in the CAD/CAM field.

In this study, the electrochemical discharge machining (ECDM) process was used to fabricate a microchannel on polydimethylsiloxane (PDMS), which is able to fabricate channels on the non-conductive materials at low cost and acceptable material removal rate (MRR). One of the main advantages of this method, in addition to much less time and cost, is the possibility of achieving high depths (up to 1000 μm). For this purpose, the effect of electrolyte concentration, rotational speed, feed rate, and machining voltage on the surface quality and surface roughness was investigated in the PDMS micromachining. It was found that the ECDM is capable of fabricating the channels with the surface quality similar to lithography. Also, with increasing the machining voltage and electrolyte concentration, the MRR increases and the possibility of mechanical contact between tool and workpiece decreases. Increasing the machining voltage and also the electrolyte concentration changes the machining regime from contact machining to electrochemical machining. Increasing the machining voltage from 38 to 42 V increases the channel cross-section by nearly 40%. Also, the surface roughness increases by 36% with increasing the voltage from 38 to 42 V. Changing the rotational speed from 0 to 10,000 rpm, due to the reduction in the thickness of gas film, reduces the side sparks and concentration of the sparks on the bottom of the tool, which reduces the surface roughness. The Response Surface Method was used to achieve a mathematical model between inputs and outputs. The model represented a Quadratic Equation to predict the outputs.
