What Are DMLS Crowns?
DMLS crowns are fabricated using Direct Metal Laser Sintering (DMLS), a cutting-edge 3D printing technology. This process uses a laser to selectively fuse metal powder particles layer by layer, creating a highly accurate and customized crown. The manufacturing process for DMLS crowns includes the following steps:
Digital Scan
An intraoral scanner takes a digital scan of the patient’s tooth or the area requiring the crown. This scan generates a precise 3D digital model of the tooth and its surrounding structures.CAD Design
The digital scan is imported into computer-aided design (CAD) software, where the crown is designed based on the patient’s unique dental anatomy and requirements.DMLS 3D Printing
The CAD design is sent to a DMLS 3D printer. The printer uses a laser to sinter metal powder particles layer by layer, constructing the crown with exceptional precision.Post-Production Processes
After 3D printing, the crown undergoes additional procedures such as heat treatment and polishing to enhance its mechanical properties and aesthetics.Cementing the Crown
The finished crown is cemented onto the prepared tooth using dental cement, ensuring a precise and durable fit.
DMLS technology allows for the production of highly precise, customizable, and biocompatible dental crowns, making it a significant advancement in restorative dentistry.
The DMLS Process | DMLS Crown | CAD CAM Crown In Vadodara
- DMLS is a form of 3D printing that uses a laser to melt metal powder particles together to form solid objects.
- The process begins by creating a 3D model of the dental crown using computer-aided design (CAD) software.
- They then loaded the model into the DMLS machine, which spreads a thin layer of metal powder over a build platform.
- The laser selectively melts the powder particles in a predetermined pattern, according to the 3D model of the crown. The build platform then moves down, and another layer of powder is added and melted. This process is repeated until they build the entire crown up.

- One of the key advantages of DMLS crowns is their precise fit. With traditional crown fabrication methods, dentists often face challenges in achieving an accurate fit due to manual errors or inconsistencies in the manufacturing process.
- However, DMLS technology ensures a perfect fit by precisely layering and fusing metal particles according to a digital design. This results in a crown that seamlessly integrates with the patient’s natural dentition, providing optimal functionality and comfort.

Materials Used for Biocompatible DMLS Crowns
Biocompatible metal alloys are commonly used for DMLS crowns to ensure safety and durability. The most frequently used materials include:
Cobalt-Chrome (Co-Cr)
Cobalt-chrome alloys are widely used for their exceptional durability, biocompatibility, and wear resistance. These alloys are ideal for long-lasting dental restorations.Titanium and Titanium Alloys
Known for their low density, high corrosion resistance, and excellent biocompatibility, titanium crowns are lightweight and suitable for patients with metal sensitivities. They are a great option for lighter, more patient-friendly restorations.Other Metal Alloys
Alloys such as stainless steel, gold, and precious metal blends (e.g., gold-platinum) are also used. These materials are chosen based on the patient’s preferences, specific dental needs, or aesthetic considerations.
