The article aims to describe the technique of designing and fabricating ear prosthesis with the integration of computeraided design and computer-aided manufacturing (CAD/CAM) versus a conventional method. Background: The use of rapid prototyping for prosthesis fabrication preceded by the generation of ear prosthesis design utilising the computed tomography data of the patient are recent advance technologies. Case description: A 6-year-old boy came with congenitally missing right ear. The healthy left ear was mirrored and printed using the 3-dimensional (3D) printer. Since there was a tissue remnant on the affected side of the patient's ear, the printed ear model was copied in wax. The incorporation of CAD/CAM eliminated the conventional technique involving impression taking of normal ear as a model. Thus, fabrication procedure was simplified, ensuring rapid production. Conclusion: The dimension, shape, and anatomic contour of the ear prosthesis were quite similar to those of the normal ear. This outcome suggested that using the CAD/CAM system to fabricate ear prosthesis from computed tomography data is a practical technique which can be used in a clinical setting. Clinical significance: Rapid prototyping techniques used in this case gave the highest possible level of accuracy in size, shape, and position of the prosthesis. It also decreased the patient appointments and fabrication time compared to the conventional technique.

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.

This review focuses on fast prototyping advancements in the field of maxillofacial prosthodontics, as well as the various methods for fabricating maxillofacial prostheses. As of date, the interface and software used for processing and designing maxillofacial prostheses are costlier, atypical for the specific purpose, and only reachable to highly trained dental specialists or computer-aided design (CAD) engineers. This review is a summary of all rapid prototyping trials conducted in the mentioned context of three-dimensional (3D) printing of maxillofacial prostheses, treatment modalities, and future perspectives relating to rapid prototyping in dentistry. We performed a search of relevant articles on Google Scholar and PubMed, which yielded a total of 21 articles for full-text reviews. After excluding some articles based on the exclusion criteria, a review was conducted. This study gives a comprehensive discussion of current issues and future ideas for integrating digital technology with conventional techniques.
