Dental restorations and prostheses are meant to enhance the patient's oral health. However, since they affect the smile, they must be highly aesthetic to blend with other teeth and provide a natural look.
For this reason, dentists and laboratory technicians have several tools that help them achieve fine finishes and smooth and brilliant polishing on any restoration they make.
One of these tools at their disposal is the dental lathe. A machine that can be equipped with burs and mops to enhance the restoration's appearance.
What Is A Dental Lathe?
A dental lathe is a dental laboratory machine designed to polish different types of restorations and cut and trim their edges. Therefore, providing the practitioner with the tools necessary to create a prosthesis or restoration with high-quality finishes.
A dental lathe is a simple but effective machine. It consists of a large high-speed motor that causes the spindles at the side to spin.
The practitioner can place different polishing or abrasive tools in the spindles. Therefore, when the dental lathe machine is turned on, the polishing attachments begin spinning at high speed. The practitioner only has to press the restoration or prosthesis against the spinning tool to polish or trim it.
There are different dental lathe models available. Some of them feature a single spindle, while others feature two. In this case, the spindles are located at both ends of the machine.
Furthermore, some models are integrated with lights to improve viability while working.

For safety measures, these devices are fixed directly to the workbench. This provides stability and prevents the device from moving or vibrating.
Also, some models are equipped with suction boxes. These boxes are placed around the spindle area and suction any debris and particles produced while polishing and trimming.
Furthermore, other models come with a clear plastic cover that separates the spindle from the practitioner. This cover works as a protective barrier that blocks any debris that might be ejected and fly toward the practitioner's eyes.
How Does A Dental Lathe Work?
The dental lathe works with ease. The machine is electrically driven, meaning that the practitioner just has to plug it into a wall outlet and press the switch to activate it.
Also, it has a safety mechanism that keeps the spindle in place. Furthermore, the head of the device can be replaced with different models to fit various polishing and abrasive tools.
