A method of formulating a reinforcement lithium disilicate ceramic ingot was proposed. The ceramic ingot was broken manually with a mallet to finer particles. The sectioned ingot is ball milled along with 10% of nano zirconia by weight to obtain the desired powder. The reinforced powder is condensed in a 5 ml disposable syringe by powder slurry technique. The compacted ceramic were sintered at 900°C to obtain ceramic ingots. The reinforced ceramic ingots were used in pressable ceramic machines to obtain the desired advantages of zirconia reinforcement and pressable ceramic system.

| Introduction|| |
Dental ceramic is widely preferred indirect restorative material. The clinical usage is enhanced with the ceramic advancements. Various modifications and techniques have been adapted to improve the strength of ceramic to increase its applications and has been well-documented.,, Though increased application and newer material are available, the lacunae exist in enhancing the usability of conventional ceramics. This procedure describes a method of customizing a pressable ingot with reinforcement of nano zirconia particles to achieve better strength and increase the applications pressable ingots.
| Technique|| |
- Manually break the ceramic ingot into small particles with the mallet
- Ten percentage nano zirconia particles were added to ceramic particles and ball milled for 24 h to obtain the desired ceramic particle size, and uniform manipulation of zirconia
- Cut the center of a 5 ml disposable syringe (DISPOVAN; Hindustan Syringes & Medical Devices Limited, India) [Figure 1]
- Combine the reinforced zirconia lithium silicate powder and modeling liquid (IPS Classic; Ivoclar Vivadent Inc.) to desirable consistency
- Load the syringe with manipulated material and through the open-end
- Condense the mixture mechanically through the open-end of syringe [Figure 2]
- The packed material is removed and sintered in a ceramic furnace at 900°C to form an ingot [Figure 3]
- The reinforced sintered ingot was used in the pressable ceramic machine (Programat EP 5000/G2; Ivoclar Vivadent Inc.).
| Discussion|| |
The use of reinforced lithium disilicate ingot enhances its usage. The properties of reinforced ceramic porcelain are anticipated to increase because of the nano zirconia reinforcement. The procedure adapted can be an additional step in fabricating procedure but this simplified technique enhances its applications. In addition, more analysis is essential to recognize the variations in the material properties of reinforced ingot caused due to the procedure in fabrication.
| Conclusion|| |
A method of fabrication of reinforced ceramic ingot was elucidated. The technique can increase material properties and function.
