View clinical trials related to Le Fort; I.
Filter by:Background: In orthognathic surgery, virtual planning is gradually taking over in clinical practice. To start with, virtual surgery planning (VSP) is believed to be less time-consuming and less expensive than conventional surgery planning (CSP). Moreover, the improved visualization of craniofacial deformities, such as occlusal canting and asymmetries, is a further advantage. Aim: To assess the result of Le Fort I osteotomy using CAD/CAM and 3Dcustomized titanium plate with virtual planning in orthognathic surgery. Materials and Methods: 8 patients with vertical maxillary excess will be included in the study. Le Fort I osteotomy using CAD CAM surgical guide and 3Dcustomized plate will be done for the study group. All patients will be followed clinically and radiographically for one month.
The goal of this clinical trial is to show the effect of patient specific lateral nasal wall osteotomy to the pterygomaxillary separation during Le Fort I down-fracture. Participants will be divided into two treatment groups. In study group, surgery planned according to the patients' indivudial anatomy and in the conventional group, surgery planned according to mean anatomical datas. Researchers will compare patient specific lateral nasal wall osteotomy to see if it affects the pterygomaxillary junction seperation during le fort I downfracture.

Virtual Surgical planning (VSP) has significantly improved many aspects of oral and maxillofacial surgery. A very important aspect is surgical accuracy and precise transfer of the surgical plan to the operating theatre and reduction of operative time. Conventional treatment planning for orthognathic surgery, although proven to be reliable, has many drawbacks. Computer guided splintless maxillary orthognathic surgery has been recently performed with predictable outcomes. More than one design of PS osteosynthesis has been used in recent trials. Nevertheless, which design is more superior to the other is a topic yet to be addressed. Either a one-piece fixation device spanning the length of the Le Fort 1 osteotomy or the fixation can be provided by more than one device placed at the load bearing buttresses. The superiority of 4 fixating patients specific plates compared to the other will be determined after evaluating many outcomes including accuracy, intra operative time, post-operative complications. The goal is to take a step towards determining which design is the best for performing splintless maxillary orthognathic surgery in terms of accuracy and least complications for the correction of prevalent dentofacial deformities. Beside the evaluation of accuracy, the two different designs will be compared in terms of operative time and post-operative complications.
