DIGITAL TECHNOLOGY
Real jaw movements and face morphing on the digital patient: production of functional restorations in only two chairside appointments Example of a full-digital workflow based on the production of a demo mock-up. The tools for patient diagnostics as well as the design automations used allow for a precise functionalisation of the prosthetics in the digital world, providing patients with customised restorations in only two chairside appointments.
T
he latest technologies and software innovations in terms of patient data acquisition permit the production of functionalised and aesthetic restorations in considerably shorter times. Through a demo case of a mock-up, this article describes a workflow based on Zirkonzahn’s patient diagnostics tools and design automations allowing for the manufacture of precise, individual dental prostheses in only two chairside appointments. A comparison between the produced demo mock-up and the natural teeth is also displayed, to show the mockup’s high level of customisation and natural effect achieved with the workflow. First chairside appointment During the first appointment with the patient, the practitioner records the patient’s data and oral situation by taking 2D pictures of the face as well as digital impressions through the intraoral scanner. After the visit, the dentist sends the recorded data to the dental technician, who creates a virtual patient folder in the archive software, saving and storing all patient information for future usage. Based on the 2D pictures and intraoral scans, the dental technician designs a first set-up by means of the Smile Creator module included in the Zirkonzahn.Modellier software, in order to create a preview of the potential new smile. With the Smile Creator, the dental technician can design the tooth setup based on the natural teeth of the patient, or use the virtual libraries of natural tooth sets available in the software. In addition, the dental technician can apply different tooth sizes, display the teeth in a realistic dentine colour, as well as integrate different reference lines into the 2D pictures for

better tooth alignment (e.g. the smile line). The completed setup can then be exported as a 2D or 3D file and saved in the software for future designs. Second chairside appointment During the second appointment, the dentist and the dental technician show the digital smile
preview to the patient. If the patient is satisfied with the aesthetic result, the dentist continues the treatment according to the restoration type. This demo case for the creation of a mockup shows the workflow generally used for treating complex cases on implants. In such situations, the dentist employs the following patient diagnostics tools:
