Chairside vs. Lab-Centered Intraoral Scanner Workflows: Which Fits Your Practice?

The quick answer: most general practices get the best return from a lab-centered workflow, where you scan chairside and send the digital file to your lab for design, milling, and finishing. A full chairside workflow, where you also design and mill in the office, makes sense when you place a high volume of single-unit restorations and have a team ready to own CAD and milling. Many practices land in between. Here is how to decide based on your restorative volume, your team, and how closely you want to work with your lab.

What is the difference between a chairside and a lab-centered scanner workflow?

Both workflows start the same way: an intraoral scanner captures a 3D digital impression in place of trays and impression material. The difference is what happens next. In a chairside workflow, the practice designs the restoration in CAD software, mills it on an in-office unit, and stains, glazes, or sinters it before seating, often in a single visit. In a lab-centered workflow, the scan is sent digitally to a dental laboratory, where technicians design, mill, and finish the restoration and ship it back for seating at the next appointment. A hybrid approach keeps simple single units chairside and sends everything else to the lab.

Chairside vs. lab-centered workflows at a glance

Why does the scan itself matter so much?

Whichever workflow you choose, the digital impression is where accuracy is won or lost. A clean scan captures margins and contacts without the voids, pulls, and distortion that can affect conventional impressions, and you can check it on screen before the patient leaves. That clean data is what drives better-fitting crowns and bridges and fewer remakes and chairside adjustments. In practice, the scanner is the one piece of equipment every digital workflow shares, so it is the right place to start.

When does a chairside workflow make sense?

A chairside setup tends to pay off when most of these are true:

• You place a high and steady volume of single-unit crowns and onlays
• Same-day delivery is a meaningful part of how you market the practice
• A team member is ready to take ownership of CAD design and the mill
• You have the chair time and space to absorb milling and finishing in the schedule
• Your case mix is weighted toward posterior single units rather than complex restorative work

The tradeoff is that chairside dentistry turns part of your practice into a small production lab. The equipment, maintenance, materials inventory, and staff training are yours to manage, and the time spent designing and finishing is time away from other procedures.

When is a lab-centered workflow the better fit?

For most general dentists, scanning chairside and partnering with a digital lab is the more efficient path, especially when:

• Your restorative volume is moderate or varies month to month
• You want to go digital without buying a mill, furnace, and design software
• Your cases include bridges, implant restorations, full arch work, removables, or high esthetic anterior units
• You would rather keep chair time focused on patient care than on design and finishing
• You value technician input on design, shade, and material selection

A lab-centered workflow also scales with you. The same scanner and the same digital submission process cover a single crown, a multi-unit zirconia bridge, or a full arch case, so there is no ceiling on what you can send.

How do team adoption and lab collaboration factor in?

Team adoption is often the deciding factor. Scanning alone is quick to learn, and assistants can take on much of it with good training. Adding in-office design and milling raises the learning curve and makes the workflow depend on one or two trained people. With a lab-centered approach, your team focuses on capturing a complete scan and communicating the case clearly, and the lab handles the rest. Strong digital collaboration helps too: being able to send scans instantly, discuss a case with a technician, and track it through an online portal keeps a lab-centered workflow fast and predictable.

The bottom line

If high-volume single units and same-day delivery are central to your practice, a chairside workflow can be worth the investment. For most general practices, the better move is a strong intraoral scanner paired with a digital lab partner, which delivers accurate impressions, a broader range of restorations, and less equipment to manage.

Bayshore Dental Studio built its digital workflow around exactly that model. The IntelliScan 3D Model Y is an open system scanner you own outright, with no subscriptions or per-scan fees, 10 µm scan accuracy, a 30-day money-back guarantee, and a 5-year warranty. Scans go straight into Bayshore's fully digital lab workflow, and practices that join Bayshore Scans Club can save up to 50% on lab fees with same-day U.S.-based support and ongoing training. From single Z Crown zirconia units to full arch cases, send your next digital case to Bayshore and see how a lab-centered workflow fits your practice.
