Back in march this year, for the 3Shape Navigate event, I was asked to reflect on how digital technology enhances my workflows and communications with my lab. I asked my lab partner Yassine, a master dental technician, from Dental Excellence Laboratory, to join in and reflect on the five key areas that have significantly improved by digital workflows.
The way that we used to work before, with conventional analog impressions, had problems with accuracy, deliveries, and the operational side of things; there was a whole host of problems. According to Yassine, ‘digital intraoral scans are more accurate and precise to work with and of better quality than analog impressions. The result being a more predictable outcome. My daily work has improved, thanks to the introduction of the digital workflow.’
Digital scans improve Yassine’s lab work at Dental Excellence Laboratory in four ways:
Yassine advises conventional labs to speak with a digital lab to better understand the benefits of the digital workflow. Concluding that analog workflows cannot compare to digital, and that digital dentistry is “the way forward and the future.”
The benefits of digital dentistry are not only in the ease of communication between lab and clinic, it’s also clearly illustrated in treatment workflows.
Digital technology enables communications to be smoother and more efficient when it comes to implant planning, which comprises 80% of my practice’s work. For one, with a digital scan, the lab technician can digitize the actual restorative elements. With implant restorative cases, every element is crucial for minimizing the level of inaccuracy.
Digital dentistry mitigates risks and errors. Ultimately meaning that the fit of any restorative work is absolutely spot-on.
In the session, I demoed a smile makeover case in which I began the workflow with a 3Shape TRIOS intraoral scan. The scan was used to digitally evaluate the patient's mouth, simulate a smile, and then digitally communicate this with his lab.
With the digital dental impression, I can discuss treatment options and the treatment plan with the patient. Once the clinic part is done, the scan is sent off to the lab to create a diagnostic wax-up, which the restoration is based on.
Yassine reflects on the lab side of the workflow - which looks as follows:
“We can also compare the smile design to the upper and lower arches, to the opposing arch, and we are ready to print. After three hours, the printed model is ready.”
Digital workflows enable me to decrease the number of patient appointments down from four to two with clear aligner treatments. This table breaks it down for every appointment in the workflow.
|Appointment number||Digital workflow||Analog workflow|
|1||Scan patient, pictures, simulate “before” and “after” on screen||Patient consultation|
|2||Deliver clear aligners||Analog impressions and pictures|
|3||X||Show simulation of “before” and “after” for the alignments|
|4||X||Physically fit the clear aligners|
For labs, there are major advantages with digital clear aligner workflows. In the analog process, where we start with conventional dental impressions, the lab receives these by post, they then have to cast these up into models, and use a series of different models to make and create the aligner system. This would then need to be returned to us as a simulation to share with the patient.
Within the digital workflow, this is all done simultaneously. As soon as the digital scan is taken, a simulation of the clear aligner system is created almost immediately, and then the clear aligners are printed and delivered to us within a week.
