Sintered "3D" Metal Appliances

The Future is Now.  Try our Custom-Fit 3D Bands Today.

All Sintered Metal Appliances are available with bands, full crowns, or open occlusal crowns.  As we stated earlier, there are no more band fitting appointments and painful separators!  Each band or crown is custom made to the 3D scan you took of the patient.  All path of insertion complications are considered at the time of CAD design leaving you a hassle free delivery to your patient.

The simple answer...

A machine shoots lasers into a metal powder to "print" the 3D part that was designed using software in either Stainless Steel or Chromium Cobalt alloys.  A build tray adjusts so that the parts can be built layer upon layer.

It requires very expensive equipment and very technologically advanced software to do...but it results in a hyper accurate fit.

For the tech nerds, according to ScienceDirect.com... Selective laser sintering (SLS) technology (invented in the mid-1980s by an American businessman) is a rapid manufacturing technique, which uses high-power CO2 lasers to fuse particles together. The laser sinters powdered materials (metallic, ceramics, or polymer materials like white nylon powder). For each successive laser scan, the build platform or bed is to be lowered. The unique feature of this process is that it repeats one layer at a time until it reaches the desired height of the object. During the building process, it does not need any additional support materials because the unsintered support from other powders surrounds and protects the model. The unsintered powders are manually removed after printing. SLS produces durable, high-precision parts, and it can use a wide range of materials. It is a perfect technology for fully functional, end-use parts, and prototypes.

  • Digital accuracy & precision fit
  • Made of Stainless Steel, rather than Chromium Cobalt, which allows us to use on ANY fixed appliance!
  • Lower profile and more comfortable for the patient
  • No separators needed
  • No band fit appointments needed
  • Easier to seat and bond

When we first ventured into Sintered Metal Appliances, Chromium Cobalt was the only option we had.  Chromium Cobalt is a metal alloy used commonly in sintered orthodontic appliances because of its strength and durability.  However, unlike traditional 304 and 316 Stainless Steel used in orthodontics, Chromium Cobalt is not as flexible, thus not as adjustable as a stainless steel wire...and that is exactly the feedback we received.

Because of this, Dobson Ortho Laboratory utilizes STAINLESS STEEL for our Custom-Fit Bands, so we are welding the same metal alloys, rather than welding cobalt to stainless steel.  This results in a stronger weld and a more flexible option for making a Sintered Metal Appliance.

Reliance Orthodontic Products has been one of the most trusted names in our industry, which is exactly why we recommend their products as part of your bonding and delivery protocol for Sintered Metal Appliances.  Before you delivery the appliance, make sure you have the following:

  • Blue Gel Etch (REF# BEGS)
  • Bristle Brushes (REF# BB250)
  • Mixing Wells (REF# MXW)
  • Assure Plus (REF# PLUS)
  • Self Mix Band Lok (REF# SMBLB)

All of these items can be purchased directly from Reliance Orthodontic Products by calling 800-323-4348 or ordering online at RelianceOrthodontics.com.

Reliance Orthodontic Products has worked with orthodontists to publish this delivery protocol on RelianceU.tech.  All information on our website is derived from the protocol as published by Reliance and published or linked on our website for your convenience.  Click HERE to view the printed version of the Delivery Protocol.

Our lab DOES NOT own an SLS printer that is used to print the custom sintered appliances.  We have to send the design to a 3rd party to print.  BEFORE YOU ORDER, please note that these types of appliances are NON RETURNABLE as they are custom made to your patient.  You are responsible to ensure that the scans that you have sent to Dobson Ortho Laboratory are complete and accurate.  We can only warranty the fit to the models provided.

If you decide to change the design or cancel the appliance after it has already been sent out, you will be responsible for the charges incurred for the labor and materials.

Ordering a Sintered Metal Appliance REQUIRES intra-oral scans.  We cannot provide an Sintered Metal Appliance on plaster casts.
