Dental Ceramic Glass Block Lithium Disilicate Press Ingots HT/LT for Veneer Anterior Crown Inlaid Lab Material 10pcs/Box

• Dental Glass Ceramics (Ingot) is a worldwide popular dental all-ceramic material with highly bionic aesthetic effect. With its exquisite design experience, good strength and higher casting accuracy, it can effectively promote the pleasant cooperation between the technician end and the clinical end, and provide a comfortable diagnosis and treatment experience for both doctors and patients.

• Natural coloration with excellent aesthetic effects.
  
• Suitable for ultra-thin veneers, with enhanced acid resistance and stain resistance
  
• Minimal reaction layer, facilitating easier handling.
  
• Reliable strength with no risk of chipping.

• Material: Lithium Disilicate/Ceramic glass

• Porcelain block type:
  (Depending on the different permeability of the porcelain block can be divided into 2 categories)
  1. HT (very transparent)
  2. LT (Low transparency)

There may be a certain difference between the displayed temperature of each press oven and the actual temperature inside the oven due to model and maintenance in differences. When you use press ingots, please check if the press molding procedure is suitable for your press oven; If the edge of the restoration is incomplete or if the ring is cracked during the press flow process, please increase the maximum temperature by 3 ℃ and start again; If there are traces of tiny air bubbles on the catering surface, please lower the maximum temperature of 3 ℃ and start again; Discover the optimal press flow temperature suitable for your press oven by the above means.
