Wow, you know more than I do right now! I haven't seen anything about the training dates for the larger mills yet. I know we are training on the PM1 right now, but that is only for blocks and not disks.
When we finally release 3Shape 2017 for our customers we will follow shortly after that with the release of our Digital Denture Professional (DPP) add-on software. This will give the option to be able to mill the teeth individually, in sextants, or full arches for bonding to the milled denture base. If you don't want the option to mill the teeth, and just want to use carded tooth stock, you won't have to buy the DDP add-on (last thing I was told).
Ide alized workflow with DDP will be as follows:
1. Dentist/Denturist will take preliminary impressions and a centric tray bite registration. They will also use our UTS-CAD to take measurements for the Campers Plane and Bi-pupillary Line. These will either be scanned in the office or sent to the lab for scanning. No need to pour impressions.
2. Lab will scan (or accept scans) and design combination custom tray / bite rims. The bite rims will have an area designed into it to accept our Gnathometer CAD, for the clinician to take an intraoral tracing for determining the VDO. These get sent back
3. Clinician will border mold and take a wash impression inside the tray/bite rim. At this point they can mark the high lip line, mid-line, cuspid line. If the scanner being used has the ability to do texture scanning, this can be done in marker. If not then either a positive or negative mark must be added to see these references in the scan. The clinician will then insert the Gnathometer CAD into the bite-rim and determine the VDO and lute the upper and lower impressions with bite registration or impression material. This then gets scanned or sent to lab for scanning.
4. Final impression / Bite registration gets scanned and sent to DDP software for design. Cast analysis is done in the software, teeth are picked from all Ivoclar or Candulor molds and automatically set. Lab tech will make any changes for esthetics, characterization or function. Tissue is then designed/characterized and either a wax-tryin (actually wax and carded/milled teeth) or what is called a Monoblock (solid white denture base and denture teeth) is milled for try-in. These are sent back to the clinician for evaluation with the patient.
5. The clinician tries in the Monoblock dentures with the patient and evaluates the mid line, esthetic plane, fit, etc. If nothing needs changing, the clinician calls the lab and tells them to mill the finals. If changes are needed, then the monoblock can be added to, adjusted, marked on, or even have another wash impression taken inside it. This then can be returned to the lab for adjustments and/or rescanning.
6. If all was good the lab will mill the denture base and teeth (if milling teeth) and bond the structures together, polish the outer surfaces (no pumice really required, as the mill creates a very shiny surface already). The finished dentures are returned to the clinician for insertion.
These are the basic steps for a full U/L denture. There will be similar workflows for full upper or lower against natural dentition, and immediate dentures (removing teeth in the software). Of course some steps will be able to be skipped or modified to suit your workflows.
