“…Lastly, customized titanium plate shape and thickness can be designed preoperatively to endure soft tissue tension and mastication. 8,9,[15][16][17] x-, y-, z-axis measurements at 7 maxillary landmarks using superimposition software program of virtual surgery data and postoperative CBCT image confirmed an error <1 mm. Posterior landmarks exhibited relatively larger range of errors, possibly due to measurement errors which may occur during acquisition of STL file and superimposition with T1 and Tv.…”

“…Predicting hard tissue movements through simulation, and using new materials from CAD/CAM and 3D printing technology have helped many surgeons. [15][16][17] As new technologies develop in the field of oral and maxillofacial surgery, our attitudes in accepting these technologies will change the future of our surgeries.…”

After Le Fort I osteotomy was first performed by von Langernbeck in 1859, there has been many improvements since. Research on and development of Le Fort I osteotomy procedure has shown downward movement of the maxilla to exhibit lowest stability and accuracy. However, maxillary downgraft movement is necessary in orthognathic patients with insufficient vertical length of the maxilla, but fixation of the maxilla after elongation is often very inaccurate. In this study, the authors utilized 3D virtual surgery, CAD/CAM-assisted 3D printing technology to overcome such limitations of maxillary total elongation. In addition, accuracy at 7 different landmarks from superimposition of virtual simulation data and postoperative Cone-beam computed tomography (CBCT) data were measured. Although posterior maxilla exhibited bigger range of errors, an error of <1 mm was measured at all 7 landmarks. Operation time was greatly shortened with cutting guides and customized plates. Although this study is a single-case study, this study shows increased accuracy and efficacy from application of 3D virtual surgery, CAD/CAM, and 3D printing technology.

“…Patient-customized OGS using customized fixation plate after the virtual simulation is a more effective strategy than using CAD-CAM splints alone [ 25 ]; however, some errors in the diagnosis and treatment planning may occur due to limitations in manipulating 3D data on a 2D screen [ 26 ]. In this study, we used customized guides, plates and PSPDs for OGS.…”

“…In addition, it provides a methodology to measure the 3D volume of the space between the condyle and fossa. Although the accuracy of OGS using a customized plate has been reported [ 25 , 26 ], surgeons and orthodontic doctors should be aware of the possible errors in surgery due to improper process of collecting patient-related data, processing digital data, and fabrication of patient-customized materials.…”

Objective: Orthognathic surgery (OGS) is a surgical intervention that corrects dentofacial deformities through the movement of maxillary and mandibular segments to achieve adequate masticatory function, joint health, and facial harmony. However, some patients present with occlusal discrepancies, condylar sag, and/or temporomandibular disorders after OGS. Various methods have been employed to solve these problems after surgery. This study aimed to evaluate the effectiveness of early screw removal in patients with occlusal discrepancies after OGS using three-dimensional cone-beam computed tomography (CBCT). Methods: In 44 patients with dentofacial deformities, patient-customized OGSs with customized plates were performed to correct facial deformities using customized guides with computer-aided surgical simulation. Of the 44 patients, eight patients complained of occlusal discrepancies and temporomandibular disorders after OGS. These eight patients underwent screw removal under local anesthesia around four weeks. The temporomandibular joint spaces at three time points (pre-surgical, post-surgical, and after screw removal) in the sagittal and coronal planes were compared using CBCT. Results: Eight patients showed an increase in joint space on CBCT images immediately after surgery (T1), but after early screw removal (T2), these spaces almost returned to their pre-surgical state, and the temporomandibular joint problem disappeared. Conclusions: The removal of screws located in the distal segment under local anesthesia between three and four weeks post-surgically may be a treatment option for patients with post-OGS occlusal discrepancies, condylar sag, and/or temporomandibular disorder.
