Patients cannot wear ocular prostheses after undergoing orbital exenteration. They require a facial prosthesis to obtain a more favorable appearance, which greatly affects their social life and psychological health. In addition, conventional prosthesis-making processes require substantial time and expense. The economic burden is particularly heavy on children, who may require many prosthesis replacements as they mature. We report a method of fabricating a facial prosthesis by three-dimensional (3D) facial scanning and 3D printed for a 13-year-old girl who underwent partial orbital exenteration for malignant ciliary body medulloepithelioma 2 years ago. The patient's facial contour was captured with a hand-held, point-and-shoot 3D scanner. A facial prosthesis was designed using a mirror image technique with 3D modeling software and 3D printed. The prosthesis was then postprocessed and cast in silicone rubber. An ocular prosthesis was integrated into the facial prosthesis. The prosthesis was retained by prosthetic adhesives. This digitally assisted, impression-free method may lower the cost and effort of making facial prostheses and improve patient comfort, especially for children.

“…Weisson et al custom-printed orbital exenteration prostheses based on facial topography scans for three patients who had stopped wearing their initial prosthesis due to issues with fit, color, or degradation. The exenteration prosthesis can integrate with a separately produced ocular prosthesis [ 119 ]. Similarly, a 3D-printed orbital mold can be used for casting of a polydimethylsiloxane exenteration prosthesis [ 120 ].…”

3D Printing in Eye Care

2021

Three-dimensional printing enables precise modeling of anatomical structures and has been employed in a broad range of applications across medicine. Its earliest use in eye care included orbital models for training and surgical planning, which have subsequently enabled the design of custom-fit prostheses in oculoplastic surgery. It has evolved to include the production of surgical instruments, diagnostic tools, spectacles, and devices for delivery of drug and radiation therapy. During the COVID-19 pandemic, increased demand for personal protective equipment and supply chain shortages inspired many institutions to 3D-print their own eye protection. Cataract surgery, the most common procedure performed worldwide, may someday make use of custom-printed intraocular lenses. Perhaps its most alluring potential resides in the possibility of printing tissues at a cellular level to address unmet needs in the world of corneal and retinal diseases. Early models toward this end have shown promise for engineering tissues which, while not quite ready for transplantation, can serve as a useful model for in vitro disease and therapeutic research. As more institutions incorporate in-house or outsourced 3D printing for research models and clinical care, ethical and regulatory concerns will become a greater consideration. This report highlights the uses of 3D printing in eye care by subspecialty and clinical modality, with an aim to provide a useful entry point for anyone seeking to engage with the technology in their area of interest.

Digital Workflow in Maxillofacial Prosthodontics—An Update on Defect Data Acquisition, Editing and Design Using Open-Source and Commercial Available Software

et al. 2021

View full text Add to dashboard Cite

Background: A maxillofacial prosthesis, an alternative to surgery for the rehabilitation of patients with facial disabilities (congenital or acquired due to malignant disease or trauma), are meant to replace parts of the face or missing areas of bone and soft tissue and restore oral functions such as swallowing, speech and chewing, with the main goal being to improve the quality of life of the patients. The conventional procedures for maxillofacial prosthesis manufacturing involve several complex steps, are very traumatic for the patient and rely on the skills of the maxillofacial team. Computer-aided design and computer-aided manufacturing have opened a new approach to the fabrication of maxillofacial prostheses. Our review aimed to perform an update on the digital design of a maxillofacial prosthesis, emphasizing the available methods of data acquisition for the extraoral, intraoral and complex defects in the maxillofacial region and assessing the software used for data processing and part design. Methods: A search in the PubMed and Scopus databases was done using the predefined MeSH terms. Results: Partially and complete digital workflows were successfully applied for extraoral and intraoral prosthesis manufacturing. Conclusions: To date, the software and interface used to process and design maxillofacial prostheses are expensive, not typical for this purpose and accessible only to very skilled dental professionals or to computer-aided design (CAD) engineers. As the demand for a digital approach to maxillofacial rehabilitation increases, more support from the software designer or manufacturer will be necessary to create user-friendly and accessible modules similar to those used in dental laboratories.
