In the orthognathic surgery, dental splints are important and necessary to help the surgeon reposition the maxilla or mandible. However, the traditional methods of manual design of dental splints are difficult and time-consuming. The research on computer-aided design software for dental splints is rarely reported. Our purpose is to develop a novel special software named EasySplint to design the dental splints conveniently and efficiently. The design can be divided into two steps, which are the generation of initial splint base and the Boolean operation between it and the maxilla-mandibular model. The initial splint base is formed by ruled surfaces reconstructed using the manually picked points. Then, a method to accomplish Boolean operation based on the distance filed of two meshes is proposed. The interference elimination can be conducted on the basis of marching cubes algorithm and Boolean operation. The accuracy of the dental splint can be guaranteed since the original mesh is utilized to form the result surface. Using EasySplint, the dental splints can be designed in about 10 minutes and saved as a stereo lithography (STL) file for 3D printing in clinical applications. Three phantom experiments were conducted and the efficiency of our method was demonstrated.

“…Orthognathic surgeries are standard procedures to correct skeletal angle class II and III deformities, dentomaxillofacial deformities, mandibular laterognathia, and maxillofacial asymmetries [1][2][3][4]. There are three standard procedures used in orthognathic surgery: Le Fort I osteotomy, bilateral sagittal split osteotomy (BSSO) and genioplasty.…”

Background. Pterygomaxillary dysjunction is the most dangerous part of Le Fort I osteotomy. Preoperative evaluation of the patient's anatomy in 3D imaging software may help to choose an appropriate surgical approach and minimize the risk of the operation. Objectives. The aim of this study was to evaluate the reproducibility of linear measurements performed at the pterygomaxillary junction using open source software. Material and Methods. The study population consisted of 101 patients who underwent a CBCT examination for reasons independent of this study. Eight anatomical landmarks in the pterygomaxillary junction were pre-defined to measure the thickness and length of this structure. Linear measurements between the landmarks were performed in duplicate by two independent observers over 14 days. The data was evaluated using Netfabb Basic Studio (Netfabb Company, Parsberg, Germany). An analysis of variance (ANOVA) studied the influence of certain factors (side, observer, and repetition) on the accuracy of the measurements. Results. The mean value of all the valid measurements was 2.76 mm for thickness and 16.71 mm for the length of the pterygomaxillary junction. ANOVA showed no inter-observer bias. None of the observers reported statistically significantly higher or lower values than the other observer (p > 0.05). The intra-observer reproducibility was better than the inter-observer reproducibility of the measurements. The intra-and inter-observer reproducibility analyzed for log-transformed absolute values of differences between the measurements was very good (< 0.5 mm mean difference for linear values reconstructed from the log). The results were from a relatively large population and offered useful and reproducible measurements using open source software during the planning of orthognathic procedures. Conclusions. The results confirmed the reproducibility of the measurements. This method may be used during the diagnostics and planning of Le Fort I osteotomy. We also propose further evaluation of open-source software programs. Their comparison may help standardize the planning of orthognathic procedures (Dent. Med. Probl. 2016, 53, 3, 320-331).
