Complete digital workflow for full oral rehabilitation with implants and veneers

The digital workflow to restore a full mouth fixed implant rehabilitation consists of 5 different steps: digital data collection, digital planning, template-guided surgery, restoration design and manufacture with CAD/CAM technology. Today’s case comes from Luis Estuardo Pacheco, an experienced dentist in Guatemala, who has established his own dental studio to help patients rebuild their smile and share a case of full oral rehabilitation with implants and veneers.

Case Profile

Fig 1: The patient who have a loss of several teeth and multiple failures in old restorations

This patient is 45 years old and had lost several teeth and multiple failures in old restorations. Due to these issues, he had some problems with chewing and pronunciation. He was dissatisfied with the look of his smile as well and decided to come and inquire about treatment to change this situation.

Digital Data Collection

Upon his arrival, the dentist used an Aoralscan 3 to capture his intraoral data. The Aoralscan 3 is a very elegant dental scanner that can capture intraoral data quickly and construct a 3D model in real time. Next,a panoramic radiograph was taken to check the bone situation of the patient from which we can evaluate the place to implant the bodies. Face scan data was then captured by a SHINING 3D facial scanner. After collecting all of the necessary information, a digital virtual patient had been established which not only made it easier for the dentist to have effective communication with the patient but also to get a more comprehensive and accurate diagnosis. At the same time, a DSD simulation was taken to have the patient foresee his future smile, which would aid greatly in visualizing the estimated treatment effect.

Treatment Plan

The initial treatment plan is to have implant prostheses in the upper jaw and lower jaw. However, due to the financial issues and the long-time treatment period, the patient finally chose to have the upper jaw repaired and left the lower jaw as is. He will have another treatment of the lower jaw in the future.

Treatment Process – Surgical Guide Design and Print

After setting the treatment plan, the next step is to design the surgical guide. The surgical guide can increase the predictability of dental implant treatment outcomes.

The designed surgical guide can be imported into Accuware for slicing and the generated document can then be imported into the printer for direct printing. After the surgical guide was ready, the dentist carried out the implant surgery for the patient, and allowed some time for wound recovery and osseointegration.

Treatment Process – Make Upper Restorations

When the patient returned two months later, the dentist rescanned to capture the intraoral data and imported it into exocad, along with the facial data, which would give a comprehensive inference to the technician who design the implant support restorations.

Upon completion, the STL document was sent to labs for manufacturing. The final restorations were made with zirconia, and a model was printed with an AccuFab-L4K using resin DM12 for quality inspection.

Treatment Process – Delivery of Final Restoration

After a professional cement process with the help of a rubber barrier, the zirconia restoration was fixed into the right place, and the patient was very satisfied with the result.

Comments from Dr. Luis Estuardo Pacheco

One advantage of a completely digital and reproducible workflow is that it facilitates not only clinical work but also laboratory work, integrating facial scanning with a face scanner and intraoral scanner produced by SHINING 3D, achieving exceptional and accurate results. Be better, be digital, be SHINING.
