Medical three-dimensional (3D) printing has expanded dramatically over the past three decades with growth in both facility adoption and the variety of medical applications. Consideration for each step required to create accurate 3D printed models from medical imaging data impacts patient care and management. In this paper, a writing group representing the Radiological Society of North America Special Interest Group on 3D Printing (SIG) provides recommendations that have been vetted and voted on by the SIG active membership. This body of work includes appropriate clinical use of anatomic models 3D printed for diagnostic use in the care of patients with specific medical conditions. The recommendations provide guidance for approaches and tools in medical 3D printing, from image acquisition, segmentation of the desired anatomy intended for 3D printing, creation of a 3D-printable model, and post-processing of 3D printed anatomic models for patient care.

“…Computer-aided design (CAD) and computer-aided manufacturing (CAM) is an important and irreplaceable technology in contemporary dentistry in Croatia and worldwide.. CAD/CAM technology was developed in 1960s first for aircraft and automotive industries, while the first CAD/CAM dental restoration was produced in 1980s ( 1 , 2 ). From the first use of CAD/CAM technology in dentistry until today, each step in CAD/CAM process was technologically improved through development and improvement of three-dimensional scanning devices, accurate and simpler softwares for design, and milling machines for precise manufacturing of dental restorations ( 3 ).…”

AimDue to fast and continuing advances in digital dental technology it is important to provide appropriate CAD/CAM education of preclinical (PS) and clinical (CS) dental students. Therefore, the aim of this study was to determine the knowledge and attitudes on CAD/CAM technology of PS and CS at the School of Dental Medicine, University of Zagreb since the obtained results can show the level of students’ knowledge and possibly a need for additional education.Materials and methodsThis study included 216 undergraduate dental students from the School of Dental Medicine in Zagreb: 77 (35.6%) of preclinical students (PS) and 139 (64.4%) of clinical students (CS). All participants filled out the questionnaire specially designed for this study. The obtained data were statistically analyzed with a significance level of p<0.05.ResultsMost of the students (182, 84.23%) heard about CAD/CAM technology at regular lectures held at the School (p<0.05). Regardless of their level of education, most of the students (204, 94.4%) did not attend any CAD/CAM course which were not held within regular lectures at the School (p<0.05). Most of PS (72, 33.3%) and most of CS (133, 61.6%) participants believe that they are not sufficiently informed about CAD/CAM technology (p<0.05).ConclusionAlthough most of the students (PS and CS) heard about CAD/CAM technology, it could be concluded that they are not sufficiently informed and that additional education on CAD/CAM technology is required. Also, CS students do not posses greater knowledge about CAD/CAM technology than PS students.

“…In a recent article, Tasopoulos et al . [ 10 ] described a similar to ours technique for fabricating a 3D printed master model by processed data obtained by a CBCT. An acrylic model of the defect was 3D printed, and the obturating part of the maxillary denture was constructed from this model.…”

“…In our case, the obturator was firmly retained and supported by the dental implants placed in the remaining maxillary bone therefore eliminating the need to extend the prosthesis into the defect to gain additional retention by using a soft permanent silicone denture reliner as was the case described in the publication by Tasopoulos et al . [ 10 ] The obturating part of the maxillary denture was constructed in hard denture acrylic resin thus making oral hygiene procedures easy for the patient to perform.…”

This case report presents an alternative method for fabricating an obturator for patients that develop xerostomia and mild trismus following radiation to the Head and Neck region. Multiple initial impression stages are avoided leading to less irritation to soft tissues and less discomfort to the patient. A 69-year-old male patient was referred to our dental practice by the Maxillofacial Surgery Department of the local General Hospital. The patient had undergone a right maxillectomy for removal of a Squamous Cell Carcinoma 2 weeks prior. Four endosseous dental implants were placed in the remaining upper jaw and 2 implants were inserted into the canine region of his edentulous mandible 3 weeks after ablative surgery. Five months following completion of radiotherapy and chemotherapy, a cone beam computed tomography of the maxilla was obtained, and a three dimensional model was constructed using an appropriate resin. Using the model as the detailed primary cast, a custom acrylic special tray was fabricated for the final impression of the remaining maxilla and the maxillary defect. An implant retained maxillary obturator and an implant retained mandibular overdenture were constructed to restore patient's speech, mastication and deglutition. The method presented here can limit the impression stages needed for construction of a maxillary obturator prosthesis to a single impression procedure advocating a partial digital workflow process. This can be very beneficial to the patient suffering from postradiation side-effects such as trismus, mucositis, and xerostomia.
