A further stride forward in next-generation integrated workflows, the TempShell solution was devised to boost the efficiency of treatment-partner collaboration. Dr Roland Glauser is a renowned international speaker, respected academic, and private practitioner in Zurich, Switzerland. An expert in digital workflows, he is one of the first users of TempShell. Here he explains the benefits it has brought to his practice and patients.

What challenges does TempShell overcome for your practice?

Dr. Glauser: One of the biggest benefits is saving time. On the very first patient visit, we take the (CB)CT, perform the intraoral scan, create the treatment plan and visually share it with the patient. We can then share the data with the lab through the cloud, which they access using DTX Studio Lab software, and our communication is very straightforward. We easily discuss any modifications, or alterations to implant placement. The provisional created by our partner lab normally arrives within two days, so TempShell has a very fast production time for us.

The temporary shell is designed and milled in-lab. Proximal wings are used to place it in the correct position.

Does this also benefit chair time?

Dr. Glauser:  Yes. For us, the TempShell provisional has been fast and easy to place on the day of surgery, which I see as being down to its precision and quality. Patients often assume that the surgical procedure will be far more extensive and time consuming than placing the temporary restoration. But this isn’t always the case with traditional prostheses: Relining, adapting, polishing, occlusal adjustment, and so on, could take far longer. The TempShell solution creates a personalized prosthetic with, in my opinion, such precision. The wings that enable the correct position of the prosthetic are small, and very few adaptions are normally needed.

A temporary snap abutment is connected to the shell, then the emergence profile is adapted, and wings removed.

The workflow means the treatment plan is developed with prosthetic considerations firmly in mind. Why is this so important?

Dr. Glauser: With the prosthetic-driven workflows that we follow, the final outcome of a functional and esthetic restoration drives the implant treatment plan. What I find most impressive today is the ability to accurately visualize the prosthesis for the patient, practice and technician with such speed. It has helped our patients understand and accept the treatment plan. Then you can select the supportive structure, abutments, provisionals, final abutments, the color and the materials and share with the lab in just a few clicks. It provides a very easy collaboration with a fully digital workflow for the desired results we need to achieve.

The TempShell individualized screw-retained provisional is placed on the day of surgery.

The workflow takes advantage of the SmartSetup procedure in DTX Studio Implant software. It automatically creates virtual teeth by analyzing the patient’s dentition. Have you found this helpful?

Dr. Glauser: It’s very helpful. It’s easy to combine the radiographic scanning, the (CB)CT data and the stl files using SmartFusion on DTX Studio Implant, which gives the detailed visualization of the anatomical situation. Then we create the treatment plan with SmartSetup, which we access in a click and only takes us a few seconds.

Ordering the TempShell is very quick. We follow the intraoral scanning workflow, which is incredibly fast, but if you take a classic impression you can still share with the DTX Studio Lab immediately.

How does it benefit the labs?

Dr. Glauser: There are many lab technicians with a lot of experience; how much time do they want to spend on the details of small, straightforward cases? With TempShell, most steps can be completed by machine, freeing up the time needed for the more complex and demanding cases. I see a huge potential for greater production capacity.
