DLyte surface finishing for the dental industry

Digitization and automation technologies for manufacturing processes have reached the prosthetic industry to improve productivity and quality of fixed and removable partial dentures, crowns and bridges, among other implantology prosthesis.

It is more and more common for companies of the dental sector to integrate new equipment into their laboratories to enhance production performance and reduce manual work.

However, polishing of metal dental pieces has remain a tedious and strenuous manual polishing method. It takes a long time, and several steps to obtain a homogeneous surface finish, offering low productivity and generating dust, dirt and noise in the laboratory.

DLyte has designed a new solution to improve competitiveness in the prosthetic market, solving problems of manual polishing and allowing you to increase the productivity and quality of the final products. Our system offers high-quality polishing for cobalt-chrome, stainless steel and titanium, while respecting tolerances, ensuring mirror finishing and homogeneous results while preserving the initial shape.

The DLyte machinery ensures better results than manual polishing in just one step. The polishing action is based on a unique and innovative technique of dry electropolishing that reaches all internal cavities that cannot be accessed mechanically and it also allows the polishing of parts from any casting, sintering or milling manufacturing process.

It’s a new standard in dental polishing.


The DLyte process does not require any rubber tip, electrolytic bathing or brushing, but simply an abrasive preparation beforehand. By reducing the traditional multi-step process, DLyte improves working conditions, and drastically reduces the toxicity of the current polishing. In addition, DLyte achieves better corrosion resistance than liquid electropolishing.

This corrosion resistance is dependent not only on the selection of the most suitable alloy, but also on the correct treatment of the material. DLyte is a unique system that is able to remove roughness drastically and improve the corrosion resistance of the metal pieces while also reducing the number of processes required in the manufacturing process.

The medical and dental device sectors require clinically proven processes and products which ensure their compliance with the most demanding safety regulations. The manufacturer must guarantee that the devices meet all appropriate requirements. In particular, they must perform a risk/benefit analysis and evaluate the biocompatibility and the toxicity of the materials used. DLyte processes have been shown to be biocompatible.


Some of the most important applications of our technology for the dentistry sector are:

  • Removable partial dentures
  • Dental implants
  • Orthodontic appliances
  • Dental crowns
  • Dental bridges

Common materials

01. Cobalt Chrome

CoCr is a popular material for medical applications, such as dental and cardiovascular implants, due to its unique combination of biocompatibility, strength, corrosion resistance, and good aesthetic appearance. Its alloys have superior mechanical properties, with high resistance to corrosion, wear, and fatigue.

02. Titanium

An appealing and popular material that can be alloyed with iron, aluminum and vanadium, among others, to produce strong and lightweight alloys. Its most useful advantages are corrosion resistance, strength-to-density ratio, biocompatibility, durability, and hypoallergenic and aesthetically attractive properties.

03. Stainless steel

An iron alloy with a minimum of 10.5 percent of chrome, which produces a passive layer that prevents corrosion. This versatile material is widely used in the industrial sector, due to its strength, biocompatibility, durability, aesthetic attractiveness, hypoallergenic properties, and profitability. It withstands high temperatures.
