Q: Does the media breakdown or need to be discarded after use?
A: The only 2 medias that breakdown from usage are the DM-CC38 Cut Media and the DM-PP10 Refine Media. When they breakdown they simply shrink in size so no need to discard. It has been found that after running those medias for average recipes, replenishing the media back to its specified depth is as follows: DCPC250- 1oz and DCPC500- 2oz. This would depend on the material being finished as different materials require different RPM and run times.
Q: What is the average total media and soap cost per cycle / per barrel:
A: Cut cycles: DCPC250- $0.72 and DCPC500- $1.44
A: Refine cycles: DCPC250- $1.16 and DCPC500- $2.32
A: Polish cycles: DCPC250- $0.09 and DCPC500- $0.19
A: Support Removal cycles: DCPC250- $0.03 and DCPC500- $0.06
Q: Can different media and different recipes be running simultaneously?
A: Because each recipe has a specific RPM and specific run time for the media and object’s material type, you cannot run multiple medias and recipes simultaneously. However, you can run similar objects / materials with the same media and recipe in different barrels.
Q: How long does it take to change medias in the barrel liner to run different media and materials?
A: 3-5 mins at the most.
Q: Who will support the AutoFinish equipment and medias?
A: Zahn Dental.
Q: What is the equipment warranty period?
A: 3 years.
Q: What are the differences between the 2 models of AutoFinish?
A: The biggest difference is the barrel size. The DCPC500 can finish approximately double the objects per barrel compared to the DCPC250. Both will finish all objects that have been validated. The DCPC250 is better for small objects like crown and bridge as there is less media to sift those objects from. The DCPC500 has the advantage or more space for movement of large objects like dentures and nightguards. It is recommended for crown and bridge labs to consider the DCPC250, Removables labs to consider the DCPC500, and full-service labs to consider one of each.
Q: What is the recommendation for cleaning the machine?
A:It is recommended to wipe all soap and water residue from the inside of the machine at the end of the day with a towel and water. Make sure
to clean the clamps well to ensure the locking mechanism locks properly.
Q: How do I remove media if it gets stuck in an object?
A: If the media gets stuck and another AutoFinish step still needs to be run to finish the object, use a dull instrument to remove. If the media gets stuck on the last step, you can ultrasonic the object in water for 1 minute and the media will release.
Q: What identifies as a Denture w/ Exposed Metal?
A: Denture that has exposed metal on the outer surface. This includes Hybrids with Ti-bases or a bar already bonded, Partial Dentures with a metal framework, and stay plates with ball clasps. This is due to the potential for the exposed metal to abrade and discolor the plastic materials.
Q: What is the difference between the Low Impact Printed Denture and High Impact Printed Denture recipes?
A: The main differences are the speed at which the machine operates and the time each cycle is run. Some Denture print materials and designs are more fragile than others which can cause fractures to occur, only when multiple dentures are run in the same barrel, on the High Impact Printed Denture recipe. If this occurs, you need to consider the Low Impact Printed Denture Recipe to avoid such fractures. Not all Print materials are the same and thickness in the design needs to also be considered.
Q: How do we protect the margins of crowns from abrasion during the AutoFinish process?
A: For Zirconia Restorations, there is no need to protect the margins due to the properties of zirconia materials. For Full Cast Restorations, you will need to fill the inside of the restoration with Henry Shine VPS Putty up to the inside of the margins.
Q: Will running the Zirconia Polish cycle more than once improve the result?
A: No. The polishing media / recipe does not change the surface of the zirconia, it is designed only to create a high shine. Running the cycle more than 60 mins can cause damage to the barrel liner due to excessive heat. If the result is less than desirable, the technician should consider changing the green state finishing protocol / tools used to ensure the surface is smooth after sintering.
