Resin Related Questions

Q: IS MIXING 3D RESIN REQUIRED PRIOR TO PRINTING?

A. 3D printing resins contain chemicals of different weights; therefore, it is essential to thoroughly mix the resin prior to starting a new print job.

  • For resin already in the resin vat, use a silicon blade to gently stir in settled ceramic
    fillers at the bottom of the resin tank.
  • Before dispensing the resin from the bottle, use a plastic spatula to stir the bottom of
    the bottle for several minutes before dispensing or mix using an automated bottle roller
    for 30 minutes.
  • If the bottle has been in storage for excess of a month, it is recommended to roll the
    bottle for 1 hour to allow ceramic fillers to reintegrate back into suspension.
Q: WHAT SHOULD I DO WITH THE RESIN LEFT IN THE VAT?

A: It is best to designate a vat with a specific resin. Store covered vat in a cool, dark area when not in use. Alternatively, unused resin can be poured into the original bottle for storage.

When pouring resin from a tank or other vessel back into the bottle, always pour through a fine mesh filter. This will trap partially-cured debris and prevent resin contamination of the rest of your bottle, prolonging the life of your materials.

Q: WHAT ENVIRONMENT SHOULD THE RESINS BE STORED IN?

A: 3D photopolymer resins are light-sensitive, sensitive to ambient office lights and sunlight from a window. Therefore, it is essential to not leave resin bottles open. Resin that has been poured into a resin tank should be covered if not used.

It is best to store resin between 65F and 85F. Printing temp should be set to 30 degrees Celsius for optimum performance if applicable. If the bottle is stored in colder lab conditions as indicated above, it is recommended to place resin bottle with lid tightly sealed in a warm water bath.

Q: WHAT IS BEST PRACTICE TO REMOVE MY PRINT FROM THE BUILD PLATFORM?

A: For best results, use spring-loaded clippers to remove printed design from supports.

Alternatively, use a sharp-edged metal spatula to carefully pry and remove the finished print from the build platform. Always remember to push the blade away from your body to avoid injury.

Q: How long does the post processing procedure usually take for a AOX provisional or restoration?

A: Total elapsed time between removing AOX provisional from the 3D printer and taking to the final light cure process will take approximately 45 minutes for an experienced technician to complete.

Total elapsed time between removing a single crown restoration from the 3D printer and taking to the final light cure process will take approximately 35 minutes for an experienced technician to complete.

Q: Total time needed for a completed denture? (Denture Base + Full Arch)

A: Total elapsed time when printing a denture base and tooth arch simultaneously will take approximately 2-4 hours to complete dependent on 3D printer type, selected layer thickness, and orientation strategy implemented.

Rodin Sculpture Related Questions

Q: How long do Rodin Sculpture restorations last compared to Zirconium blocks?

A: Rodin Sculpture has a very similar formulation to Pac-Dent’s flowable composites such as Opticomp and Optiflow. Because of this, it has the same longevity, lasting a minimum of 5 years.

Q: What is the strength comparison between Zirconium and Rodin Sculpture?

A: Rodin Sculpture may not have the same strength properties compared to Zirconia products but has a low flexural modulus meaning that Rodin Sculpture is not brittle which minimizes chance of restoration failure.

Q: If part of the full arch is damaged, does the entire thing have to be reprinted?

A: This is one of the advantages to 3D printing, you can reprint archived CAD designs and fabricate a new full arch without bringing the patient in for a rescan or new VPS impression. It is possible to repair minor chips with acrylic based composite systems.

Q: How many crowns per bottle? How many full arches per bottle?

A: Single crown weight is roughly 3-5 grams on average when accounting for support structures and uncured resin waste. A conservative crown count would be approximately 240 crowns per 1.2kg bottle of Rodin Sculpture.

Q: Print Time per crown? Print time for full arch?

A: Print speeds are determined by many factors. That being said, you can print as fast as 20 minutes per crown and 30 minutes per full arch if printing at 150μm layers depending on the 3D printer.

Q: What would you approximate the time saved to be?

A: Efficiency speeds of 3D printing and postprocessing can deliver a finished crown in ⅓ time faster compared to milling and glazing a finished crown.

Q: How would a doctor use the ADA insurance code to get reimbursements?

A: Permanent crowns printed with Rodin Sculpture qualify for ADA insurance code D2740. This is because our material can be classified as “predominantly ceramic” as it contains over 50% ceramic filler.

Software Related Questions

Q: What software do you recommend?

A: Nesting software is specific to the 3D printer used. Ackuretta Sol in combination Alpha3D, Asiga MAX in combination with Composer, etc. to generate sliced print files. Design software specific for generating dental restoration CAD files is a separate yet critical component to the esthetics of the final product. Top design suites include ExoCad, 3Shape, META, Itero.

Q: Would you say there is a steep learning curve on the software?

A: Difficult to answer- really depends on the student's ability to grasp 3D printing concepts and the experience of the instructor. In most cases, it takes a couple weeks of training to have a sound understanding.

A: Single crowns, veneers, inlays, and onlays.

Q: WHAT TYPES OF PROVISIONALS CAN BE PRINTED WITH RODIN SCULPTURE?

A: 3 unit bridges, full arch denture teeth, all-on-x Provisionals.

Q: WHAT IS THE PROCESS FOR DIGITAL WORKFLOW FOR 3D PRINTING?

A: The doctor will prep the targeted tooth/teeth, scan the mouth with an intraoral scanner to take a digital impression. The scan data will be converted to a file that can be imported to a dental design software platform such as 3Shape, ExoCAD, Meta. The restoration or denture appliance will be created and converted to a 3D printable (.STL) file.

Misc. Questions

Q: What bonding material is used for the dentures? Does Pac-Dent sell their own bonding material?

We recommend using the Denture Base material or Rodin Glaze as they are the same basic formulation as Rodin Sculpture. This means when the product is light cured, the resin will create a strong bond between the denture base and sculpture

Q: Can the Rodin materials work on Sprint Ray Printers?

Sprint Ray is a closed-system printer company, meaning that materials have to be validated by them and uploaded as print profiles. At this time, Pac-Dent resins are not yet validated by Sprint-Ray.
