Case of the Month – João Oliveira

João Oliveira

Age - 70

Country - Portugal (algarve)

Clinical Case Description

Clinical Case Description – The patient arrived at the clinic with a very advanced degradation of his oral health. He had several teeth missing in his upper jaw, decayed teeth and old fillings. One of the main consequences of molar and premolar tooth loss is the loss of the lower third dimension of the face (vertical dimension), which causes a more aged face and reduces the available space to replace the missing teeth. One of the patient’s main complaints was that he could not eat apples.

The patient sought our help to improve her chewing ability and find an aesthetic solution according to her age, which would provide her with a young and healthy smile, in line with her age and lifestyle. Our friend João Oliveira worked in customer service and wanted to improve the appearance of his smile and remember what it is to eat an apple.



  • 1st Clinical Evaluation and complementary diagnostic tests
  • 2º Implant placement surgery and provisional teeth on the patient’s teeth
  • 3rdFollow-up appointment to assess the healing and postoperative process.
  • 4thAppointment focused on dental molds for the permanent teeth and implants of the lower jaw, to be manufactured with Zirkonzahn ceramics
  • 5thPlacing the ceramic teeth on the teeth and implants on the lower jaw
  • 6thAppointment focused on dental molds for the permanent teeth and implants of the upper jaw, to be manufactured with Zirkonzahn ceramics
  • 7thPlacing the ceramic teeth on the teeth and implants on the upper jaw
  • 8thAssessment appointment and final photographs


  • 1st A clinical assessment will be conducted with the help of clinical study models, a Panoramic Radiograph and a Computed Tomography, and studio photographs for an aesthetic analysis.
  • 2nd This is the day where the surgery is performed and temporary teeth are placed, allowing the patient to see how the final work will look like. In other words, the change will be massive, the patient will already leave with a new smile on this day, albeit in provisional material.
  • 3rd This appointment is scheduled a few days after the surgery and its purpose is only to control the patient’s bite (occlusion), assessing as well the healing process.
  • 4th The appointment for the lower jaw permanent teeth is scheduled 2 months after step no. 2, this is when the bone and gum healing is completed, thus allowing one to assess the success of the implant healing.
  • 5th Placing the Zirkonzahn ceramics on the lower jaw and the permanent teeth molds of the teeth and implants of the upper jaw.
  • 6th Placing the Zirkonzahn ceramics on the upper jaw and bite adjustments
  • 7th Final photos in a photo studio


Lab-wise, our team will deal with the smile design itself to then print it using our state-of-the-art 3D printer, both for temporary teeth (which correspond to a model of the final work) and for the manufacturing process of ceramic dental pieces.

In the final rehabilitation stage (after the healing is completed), our technicians will focus their attention on the Zirkonzahn ceramic teeth, based on the patient’s aesthetics, symmetry, harmony and integration. A quality control will be conducted during this stage, assessing each stage until we reach the smile of your dreams. In this patient’s case, “prettau” ceramics were used, whose translucency and brightness match the natural teeth characteristics, to make the smile as close as possible to its natural counterpart.

Our vision of the present and the future

The CERO Project has the willingness to be different, but sometimes doing things differently does not mean they are better or worse. In our case, doing differently is shift the dentistry focus to the patient. We do not want the patient to feel like yet another number, just another a patient who steps into the clinic.
