    Exploring today's digital dental workflow

    Shaun Keating, CDT and Dr. Jack Ringer explain why staying abreast of technological developments is crucial for lab success.

    What is the dream scenario for the dentist and laboratory’s workflow? The simple answer is that the final result is achieved in an easier manner, more accurately, with less cost and in a shorter time frame. Thanks to the ever-evolving world of dental technology, we are able to experience that scenario today!

    We all know in the business and service industry that costs are higher and errors more frequent when the human element is incorporated into the workflow, versus a machine that is designed to do the same job. This is evident in virtually every industry such as automotive, aerospace, medical and yes, even dentistry. As technology has become more sophisticated and less costly, areas where it was thought that only humans could fill are now being replaced by machinery.

    So, how does this apply to the dental world? From the dentist’s perspective, machines have not replaced the human diagnosing and treating the patient… yet. Nor have machines replaced the design and artistry of the ceramist… yet. However, there is technology now that has improved the laboratory and dentist’s workflow to be more accurate, more efficient and less costly. Where this is most evident is in the area of digital impressions.

    Conventional dental impression-taking is an aspect of dentistry that by its nature can be riddled with errors that can cause greater expense and inefficiency for both the dentist and laboratory! It is estimated that a dentist pays as much as $60 per impression, not including any redoes that may occur for a bad impression. The dentist also incurs greater costs if his/her impression results in the laboratory notifying the office that they need to take a new impression thus the office incurring the expense of another appointment for the patient; let alone the frustration and inconvenience for the patient and office. From the laboratory in this scenario they also incur the expense of pouring a model they won’t use plus needing to have a new pick up for the new impression.  Conventional impressions also require the lab to pour up a stone model, which costs man-hours plus the potential for human error when stone mixing and trimming the dies. 

    Digital impressions eliminate these errors and reduce cost by getting most of the human factor out of the equation. Capturing digital impressions is easy and is as accurate, or even more accurate, then conventional impressions. There is no distortion and no need to pour a model; though if a model is desired; that model can be imprinted or milled, also eliminating any material or human error. Since the impression is sent via the Internet, there is no cost for delivery and the lab receives it immediately. Once received by the laboratory, the impression can be immediately uploaded into the design software (CAD – computer assisted design) where the technician designs the restoration and then imports that into the milling machinery for manufacturing, followed by finishing.

    With today’s highly esthetic strengthened monolithic ceramics, the lab can produce single or multiple unit crowns and onlays efficiently, accurately and inexpensively while getting them back to the dentist within a few days verses the traditional two plus weeks. Another huge advantage for the laboratories is that they can plan and design dozens of restorations to be scheduled for milling overnight when the laboratory is closed. Again, a huge time saver plus an enormous financial savings as there are no human labor costs. Obviously the one area in the digital workflow that can allow for human error is whether the person is using the digital devices correctly or not. So be it for the dentist or laboratory technician, proper training and instruction on the use of these technologies is imperative and once this is done, the potential for errors being created becomes very rare.
