Dry & Wet Milling Machines
Dental 3D Printers
A milling machine is a computer-controlled device used to produce dental prostheses, such as crowns, bridges, and implants, from blocks of ceramic, zirconia, or other materials.
The machine uses a high-speed rotating bur to precisely mill the prosthesis according to the digital design created by the dentist or technician using CAD/CAM software. The milling process results in highly accurate and precise dental restorations that fit perfectly in the patient's mouth.
Wet Milling Machine
Wet milling machine operates with a coolant or water to lubricate and cool the cutting tool during the milling process. This helps to reduce heat and friction generated during the milling process and ensures the accuracy and precision of the final restoration.
Wet milling machines are capable of milling a wide range of materials, including ceramics, resins, and metals. They can produce highly precise restorations with smooth surface finishes and accurate marginal fit.
Wet milling machines are often preferred over dry milling machines because they generate less dust and debris, making them safer and more environmentally friendly. However, wet milling machines can be more time-consuming than dry milling machines due to the need to clean and maintain the coolant system.
They also require a more extensive cleaning process between each use to prevent cross-contamination between different materials. Additionally, the use of coolant may affect the mechanical properties of some materials, such as the strength and color of dental ceramics.
Dry Milling Machine
Dry milling machine operates without using any coolant or water to lubricate or cool the cutting tool. Instead, the machine uses a high-speed spindle and cutting tool to remove material from the block of material, such as zirconia or lithium disilicate, in a process called "milling."
Dry milling machines are known for their precision and accuracy. However, the machine can generate a significant amount of heat, which can affect the quality of the restoration or damage the machine itself.
Therefore, proper maintenance and monitoring of the milling machine are important to ensure the quality of the final product.
