Aim: To develop 3D printing and dentistry methods for building physical models that enable one to simulate a sinus lift surgery. Materials & methods: The Blue Sky Plan software was used to create a digital model from the cone beam computed tomography scan of the subject’s maxilla and to design a surgical guide for sinus augmentation and implant placement. The anatomical model and surgical guide were 3D printed from dental resin. Results: Sinus augmentation and dental implant insertion were carried out on the model as examples of practical skills training for residents in maxillofacial surgery. Conclusion: The 3D-printed models and surgical guides are useful training materials. They could be helpful also in a dental practice for surgical planning and for illustrating the procedure to the patient.
The impact of 3D printing on oral and maxillofacial surgery
Journal of 3D Printing in Medicine
3D printing technology has driven major medical, dental, engineering, and education innovations. In oral and maxillofacial surgery (OMFS), 3D printing technology has been implemented to improve precision in treatment planning, increase surgical predictability, reduce operation times, and lower overall costs. Furthermore, 3D printing has opened access to surgical training, facilitated patient-physician relationships, and generated greater surgical outcomes. The aim of this review is to summarize the impact of 3D printing technology in the field of OMFS. We discuss its many applications in the management of maxillofacial trauma and reconstruction, orthognathic surgery, maxillofacial prosthodontics, temporomandibular joint (TMJ) reconstruction, dental implants (3D-printed surgical guides and 3D-printed dental implants), bone tissue engineering for maxillofacial regeneration, clinical education, and patient communication.
Journal of Stomatology, Oral and Maxillofacial Surgery, 2021
3D-printing is part of the daily practice of maxillo-facial surgeons, stomatologists and oral surgeons. To date, no French health center is producing in-house medical devices according to the new European standards. Based on all the evidence-based data available, a group of experts from the French Society of Stomatology, Maxillo-Facial Surgery and Oral Surgery (Soci et e Française de Chirurgie Maxillofaciale, Stomatologie et Chirurgie Orale, SFSCMFCO), provide good practice guidelines for in-house 3D-printing in maxillo-facial surgery, stomatology, and oral surgery. Briefly, technical considerations related to printers and CAD software, which

Background Maxillary sinus augmentation is a common method for increasing bone height for insertion of dental implants. In most cases, the graft is manually cut into a roughly appropriate shape by visual estimation during the operation; accordingly, the shape of the graft depends considerably on the experience of the surgeon. We have developed a computer-aided design/computer-aided manufacturing (CAD/CAM) technique to generate custom-made block grafts for sinus augmentation, and a customized cutting guide to precisely position the lateral wall and facilitate membrane elevation, using cone-beam computed tomography (CBCT).
Use Of 3-d Printed Models For Implant Placement - A Case Series
Long-term stability of a dental implant depends on various factors, one among them is proper position within the alveolar bone. Pre-operative thorough examination of the surgical site is preliminary step while planning dental implants. Conventional techniques such as Intra-Oral Periapical Radiograph and Ortho Pantamogram sometimes not sufficient and clinical scenario always surprises the surgeon. Later advent of Cone-Beam Computed Tomography alleviated this problem to some extent but there are some clinical situations such as resorbed ridge where better visualisation is needed. This led to the innovation of rapid prototyping techniques for the fabrication of threedimensional complex structures. This technology has numerous applications from the development of an instrument, 3-D printed anatomical models to the fabrication of 3-D printed tissues for regeneration procedures. A 3-D printed model is much more useful than plaster models in many aspects such as demonstrating anatomical structures, better treatment planning, and better understanding for the patient. Hence, this case series focuses on the use of 3-D printed models in the placement of dental implants.
Training Young Maxillofacial Surgeons or Trainees Using Additive Manufacturing
Materials Today: Proceedings, 2018
Cranio-maxillofacial surgery requires high precision to obtain the desired results. However, to perform such surgeries a surgeon has to go-through intense training. Earlier surgeon was solely dependent on the data obtained from conventional X-ray films which would give only the 2 dimensional depictions. There existed a need for a depiction of the third dimension. The virtual models were obtained by 3 d Scans but the real time performing surgery was the next step. The virtual imaging can be made physical with help of additive manufacturing (AM). AM or 3D-printed models to train new surgeons before they perform complex surgery resolves a dire need for proper training and practice. Additive manufacturing is the perfect technique to create hyper realistic training replicas of complex or rare pathologies which gives a life like feel over which a trainee can practice the art of surgery without the risk of losing an actual patient. The opportunity to use 3D Printing technology in hospitals creates a valuable learning opportunity for new surgeons. The 3D CT images are converted into lifelike, soft, 3D-printed models which can be cut, sewn and operated on. This is just a much more rapid way of expanding the circle of competence of budding surgeons. Apart from regular training, 3D-printed models can also be used in trial runs before an actual surgery is performed.
3D Printed Dental Models A comparative analysis
Materiale Plastice
The aim of this study is to compare two different methods used for obtaining printed dental models -intraoral scanning and extraoral scanning; the comparative analysis was made in correlation to the accuracy of the traditional plaster cast model. Nine dental models were obtained: three plaster cast ones, three printed after intraoral scanning and there printed after impression scanning. A total of 137 measurements (arch and tooth measurements) were done on the three types of models and a statistical evaluation was performed (t-test, Fisher Test). Our results highlighted that 3D printed dental models represent a reliable option for clinical application.
3D Print of the Maxillary Sinus for Morphological Study
International Journal of Morphology, 2017
The maxillary sinus (MS) is described as a pyramid-shaped cavity of the maxilla. Knowledge of its morphology makes it possible to define normality and abnormality so that its three-dimensional analysis can be a valuable preoperative tool during surgery in this anatomical area. The aim of this study is to present a strategy of morphological analysis of the MS using 3D printing acquired through computed cone beam tomography (CBCT) images. A cross-sectional descriptive study was conducted, including 15 subjects (8 women and 7 men). The 3D virtual reconstruction and modeling was done on the MSs bilaterally, and 30 physical models were produced on a 3D printer. The results revealed that the MSs obtained exhibited various morphologies. An individual analysis of each MS allowed the tripod nature of the MS to be defined. We also were able to observe anatomical repairs such as the MS ostium, as well as complex areas affecting important surgical decisions. This method for creating 3D models of MSs provides a new approach to understanding the precise anatomical characteristics in these structures, which cannot be assessed in the same way on a 2D screen. It may be concluded that 3D printouts of the MS are a suitable method of preoperative analysis that can be useful in educating the patient, however, less time-consuming strategies should be explored.
Imaging Science in Dentistry, 2021
Purpose: This study aimed to compare the accuracy of 3-dimensional (3D) printed models derived from multidetector computed tomography (MDCT) and cone-beam computed tomography (CBCT) systems with different fields of view (FOVs). Materials and Methods: Five human dry mandibles were used to assess the accuracy of reconstructions of anatomical landmarks, bone defects, and intra-socket dimensions by 3D printers. The measurements were made on dry mandibles using a digital caliper (gold standard). The mandibles then underwent MDCT imaging. In addition, CBCT images were obtained using Cranex 3D and NewTom 3G scanners with 2 different FOVs. The images were transferred to two 3D printers, and the digital light processing (DLP) and fused deposition modeling (FDM) techniques were used to fabricate the 3D models, respectively. The same measurements were also made on the fabricated prototypes. The values measured on the 3D models were compared with the actual values, and the differences were analyzed using the paired t-test. Results: The landmarks measured on prototypes fabricated using the FDM and DLP techniques based on all 4 imaging systems showed differences from the gold standard. No significant differences were noted between the FDM and DLP techniques. Conclusion: The 3D printers were reliable systems for maxillofacial reconstruction. In this study, scanners with smaller voxels had the highest precision, and the DLP printer showed higher accuracy in reconstructing the maxillofacial landmarks. It seemed that 3D reconstructions of the anterior region were overestimated, while the reconstructions of intra-socket dimensions and implant holes were slightly underestimated.
