Immediate loading rush cases: handling peaks without hiring
How a dental lab handles immediate loading rush cases and workload peaks without hiring: planning before surgery, ready designs, printing and outsourced CAD.
Immediate loading cases arrive with a deadline set by the surgery: the patient leaves the clinic with a fixed provisional, often on the same day or the next. When two of them land in the same week as the usual crowns and bridges, a small lab runs out of hours. This post is for lab owners who want to handle immediate loading rush cases and other workload peaks without hiring for a peak that may not last. It covers what to prepare before the surgery, how to organize the day of the case, and when to outsource the design.
Prepare everything that does not depend on the surgery
The implants’ final position is known only after the surgery. Almost everything else can be ready before it. With pre-operative scans of both arches, the bite and photos, the lab can build the tooth setup, have the clinic approve it, and prepare the provisional as a design waiting only for the connection to the implants.
What the lab needs from the clinic before surgery:
- intraoral or model scans of both arches and a bite at the right vertical dimension;
- photos, ideally with a face scan for aesthetic cases;
- the implant system, the planned abutments such as multi-unit, and the scan bodies they will use;
- the surgery date and the time the provisional is needed.
With the setup approved in advance, the day of the case is only about registering the implant positions and connecting the design to them. The setup work in exocad is described in digital full dentures in exocad, and the case connects to the Smile Creator workflow when aesthetics drive the plan.
The day of the case
After surgery the clinic scans the scan bodies on the abutments and sends the files. Scan body errors are the most common reason a rush case stops: a body not fully seated, a missing area, the wrong library. A quick check before design, following implant scan body tips, saves the hour that a new scan would cost.
The design then places the prepared setup over the implant positions, adds the screw channels and checks thickness around them, and goes to production. Printed provisionals need a resin indicated for long-term temporaries and the validated wash and cure protocol, as explained in dental 3D printing resins. The file exchange is quicker when the clinic sends through the scanner portal the lab already uses (see scanner portals).
Planning the week around peaks
A lab cannot control when surgeries happen, but it can make peaks visible. Asking clinics for surgery dates when they plan them, and keeping them in the same calendar as the rest of the work, shows a collision days ahead instead of on the morning of the case.
Standard work can often move. A crown due on Thursday can sometimes be agreed for Friday when the lab asks the clinic in time, and a rush case cannot wait. Clinics accept a change much more easily when it is announced early.
Outsourcing the design instead of hiring
Hiring a technician for a few peak weeks a year is expensive and slow, and a new person needs months to work in the lab’s style. Outsourcing the CAD design for the overflow keeps the fixed cost down: an external designer takes the cases the lab cannot design in time, and the lab keeps production, quality control and the relationship with the clinic.
It works best when it is set up before the peak. Agree on the file format, the libraries and material settings, the turnaround and how rush cases are announced, and run a few normal cases first so both sides know the routine. The lab remains the manufacturer of the device, so it keeps the design file and the records with the case, as explained in MDR and implant-compatible design files. How a working arrangement looks in practice is in outsourcing dental CAD design. For long full-arch spans, implant positions can also be recorded with photogrammetry.
Frequently asked questions
What can the lab prepare before an immediate loading surgery?
Almost everything except the final position of the implants: pre-operative scans and bite, a tooth setup approved by the clinic, the implant system and components, and a design ready to be connected to the implant positions once they are scanned.
Can the provisional for immediate loading be 3D printed?
Yes, with a resin indicated for long-term temporary restorations, printed and post-cured on the printer and equipment the resin manufacturer validated, and with the thicknesses its instructions require.
How does outsourcing CAD help with workload peaks?
An external designer takes the design work when the lab is full, with a turnaround agreed in advance, and the lab keeps production and the contact with the clinic. Paying per case avoids a fixed cost for months when the workload is normal.
