Filter by:To evaluate whether the use of augmented reality (AR) for visualizing 3D models can be a valuable addition to patient education regarding orthognathic procedures compared to using only 2D visualization (on a computer screen).
clinical and radiographic comparison between novel locating guide design with pre-bent titanium plates and 3d printed intermediate wafer to reposition the maxilla after Le Fort 1 osteotomy in orthognathic surgery (randomized controlled clinical trial)
Children with ankyloglossia (tongue tie) can have abnormal tongue function, putting them at a disadvantage when it comes to speech and articulation. Furthermore, abnormal tongue posture within the oral cavity increases the likelihood of myofunctional disorders.
Current advances in the three-dimensional virtual surgical planning (3D-VSP) of the orthognathic surgery have brought newer insights, enormous benefits and have become an indispensable aid for diagnosis, treatment planning and outcome assessment especially in the management of dentofacial deformities. The extent to which the planned surgical outcome could be achieved is dependent on the surgeon's ability to accurately transfer the planned movements to the real surgical field. Accurate repositioning of the maxilla after Le-fort I osteotomy is of utmost importance for an esthetic and functional purposes. The goal of this interventional study is to compare the 3D photogrammetry technique versus the commercial scanners for accurate repositioning of maxillary segment after le-fort I osteotomy using the reverse engineering technology. The main question it aims to answer; Is the utilization of the 3D Photogrammetry technique affect the accuracy of maxillary segment repositioning after le-fort I osteotomy compared with the commercial scanners?
A comparison of the stability of two different designs of patient specific fixation devices for the performance of splintless computer guided le fort 1 osteotomy in orthognathic surgery workflow for the correction of a variety of dentofacial deformities
The aim of the study is to evaluate the Skeletal stability of Le Fort I osteotomy using patient-specific osteosynthesis compared to Mini-plate fixation for patients with skeletal class III malocclusion.
Research studies continues to attempt testing modifications to refine the treatment protocols through computer assisted design or computer-generated surgical Wafer splints, have greatly revolutionized the incorporation of digital imaging and 3D design in Orthognathic surgery. Integrating computer guided technology in orthognathic surgery aims to to simplify workup and reduce surgical errors, eliminate occlusal discrepancy, increase the realignment accuracy of the distal segments according to the preoperative plan. Implementing a waferless technique raised the question of efficiency versus the use of occlusal wafers and whether it has a significant measurable effect on the surgical outcome and objectives. Rationale for conducting this study is to assess the difference between the effect of computer guided waferless technique and computer guided technique with occlusal wafer on accuracy of postoperative occlusion and condylar position. .
The aim of the present project is to analyze the impact from orthognathic surgery on the upper airway respiratory volume. The primary objective is comparison of differences in the in the airway changes due to maxillary movements and mandibular movements. Secondary objectives are the analysis of any correlation between the magnitude of the movement and the airway volume, correlation between the direction of the movements and the changes in airway volume and correlation with Health-Related Quality of Life (HRQoL). Expected confounding factors like smoking habits and Body Mass Index (BMI) will be analyzed.
The aim of this study was to develop a Spanish version of the Orthognathic Quality of Life Questionnaire (OQLQ) that is conceptually equivalent to the original questionnaire, as well as acceptable, reliable, valid, and responsive for use in Chilean patients with dentofacial deformities.The cross cultural adaptation process was carried out according to the recommended standard methodology with direct and back-translation.
Objectives: The aim of this randomised controlled clinical trial is to evaluate surgical accuracy and efficiency of computer-assisted jaw reconstruction using 3D-printed patient-specific titanium surgical plates versus conventional plates. Hypothesis to be tested: The investigators hypothesize that compared to conventional surgical plates, 3D-printed patient-specific surgical plates improve surgical accuracy and efficiency of computer assisted jaw reconstruction. Design and subjects: This is an open-label, prospective, double-arm, and single-centre randomised controlled clinical trial. Patients with maxillary or mandibular neoplastic, inflammatory and congenital diseases who require immediate or secondary reconstructive surgery will be invited to participate in the study. Study instruments: 3D-printed patient-specific titanium surgical plates and conventional plates. Main Outcome Measures: The primary endpoint is the accuracy of reconstruction. The secondary endpoints include the accuracy of osteotomy, reconstruction time, total operative time, intraoperative blood loss, length of post-operative hospital stay, and postoperative adverse events. Data analysis: The accuracy parameters, reconstruction time, total operative time, intraoperative blood loss, length of post-operative hospital stay will be presented as mean values with standard deviations. The post-operative adverse events will be calculated and presented as frequency with standard deviation. Expected results: This randomised control trial will prove improved accuracy and efficiency of reconstruction using 3D printed patient-specific titanium surgical plates. This study is expected to provide high-level evidence to push forward the popularity of using 3D medical printing technology in surgical field.
