“…This is where the Zbrush software and digital sculpting prove useful in designing the prosthesis. A digitally designed epithesis trial model can be printed for fitting, the same as a wax model [8]. In the traditional workflow, the next step would be to make plaster molds.…”

“…An incorrectly selected silicon base color might spoil the end result of the time-consuming work of manufacturing a prosthesis. Another possibility of facilitation is the usage of a spectrophotometer for the digital skin color assessment in order to select the appropriate silicone color for a facial prosthesis [8,16]. This utility might automate and speed up the prosthesis workflow even more and eliminate human errors, which can be made by visual perception.…”

“…An auricle or an orbital prosthesis usually fulfills aesthetic functions. The sculpture and pigmentation of the prosthesis must be at the highest possible degree of quality, so a patient can feel psychological comfort [7,8]. A nasal prosthesis, besides providing an aesthetic function, is also an important element of the patient's rehabilitation [25].…”

“…Facial prostheses provide not only an aesthetic solution by covering an affected area but also functional benefits such as warming the air, maintaining the humidity of the upper aerodigestive tract, modulating speech, and providing support for eyeglasses [1]. Prosthetic reconstruction also exerts a significant psychological impact on self-esteem and quality of life of a patient with a maxillofacial defect [7,8]. New digital technologies are now widely used in the manufacture of facial prostheses.…”

“…The digitalization of epithesis formation has also created key solutions for the communication stages of each project, as this makes it possible to consult on a particular model with other team members and/or the patient by sending and resending 3D model data files. Moreover, 3D printing nowadays is a new technology that enables the faster production of facial epitheses, with greater accuracy and efficiency [8].…”

Prosthetic rehabilitation has hardly changed since the 1970s, and it is a time-consuming process that requires great skill and precision. This article presents the workflow related to the prosthetic reconstruction of patients with extensive maxillofacial defects using digital technologies such as cone beam computed tomography (CBCT), Zbrush software and three-dimensional (3D) printing. The use of CBCT captures a 3D image of a patient’s face in a few seconds, thus shortening the time to prepare an impression and increasing the patient’s comfort. Zbrush digital sculpting software enables one to quickly and efficiently design a prosthetic restoration. Printing a trial version for a try-on, as well as designing and printing pre-cast forms, improves workflow and eliminates the chances of an error. As shown in the example of a patient after a nasal resection, CBCT, digital sculpting, and 3D printing accelerate and improve the workflow of an anaplastologist when designing the epithesis. New technologies reduce costs and save time, while helping to overcome the technical obstacles that limit access to a facial prosthesis.
