Filter by:OmniMax MMF system was designed as a device with faster application/removal time, less mucosal tissue overgrowth over the plates and screws, better tolerance for placement over prolong periods of time, better patient hygiene and a lower risk for further treatments secondary to root damage from the insertion of the screws, compared to the standard of care for maxillo-mandibular fixation and other hybrid systems. This clinical trial intends to highlight the clinical benefits of the OmniMax MMF system applied to patients undergoing repair of uncomplicated mandibular fracture(s) for whom OmniMax MMF system is used as a single mean for maxillo-mandibular fixation.
In condylar fracture surgery, reduction is the most difficult step and the key factor which determined the postoperative outcome. Therefore, the aim of this study is to develop a new instrument, which the investigators call condylar redactor, to assist the surgeon to reduct the condylar segments effectively.
Mandible fractures are a common cause of facial injury in adults. The autologous mesenchymal stem cell (AMSC) transplantation, is proposed as an alternative to the conventional graft treatment, improving bone neoformation.The objective was to evaluate the effectiveness of AMSCs application in mandibular fractures to reduce regeneration time and increase bone quality.
The sensory innervation of the face depends on the trigeminal (fifth cranial) which is divided into three branches, the mandibular nerve (V3) having motor fibers to the temporal and masseter muscle. The regional anesthesia of the face has grown in recent years for performing certain actions under light general anesthesia or sedation. The mandibular block is a simple and reliable technique but little used. Yet it reduces postoperative pain sagittal osteotomy of the mandibular branch by reducing consumption of opioids and in the oropharynx cancer surgery. Made with ropivacaine, known for its vasoconstrictive action, it also improves the visibility of the operative field during mandibular osteotomies reducing bleeding. Despite a real clinical benefit (ease of implementation, latency and duration of action of the local anesthetic), the V3 block ropivacaine is not evaluated in the maxillofacial surgery.
A new surgical approach, denoted as the supratemporalis approach, was designed to treat diacapitular condylar fractures of the mandibular condyle.This approach prevented facial nerve injury and did not increase the frequency of other complications. Therefore, the investigators suggest this surgical procedure as a routine and safe approach to diacapitular condylar fractures, which can also be applied to temporomandibular joint（TMJ）and to the zygomatic arch.
Mandibular fractures represent approximately 50% of the total facial fractures and are commonly (more than half) presented in more than one location. A few simple fractures can be treated using a conservative approach. More often, however, mandibular fractures require stabilization using open reduction and internal fixation. Simple mandibular fractures can be treated using non-rigid fixation techniques that rely on the load-sharing principle, by which stabilization is accomplished with both fixation devices and bone surfaces. On the other hand, more complex fractures with continuity defects or comminuted need to be handle using rigid fixation where the device assumes all the forces (load-bearing principle). These approaches are well established, whereas the level of evidence for the treatment of bilateral double mandibular fractures (DMF) is still scarce. In fact, which surgical treatment, or combination of treatments, leads to the best outcome and the lowest rate of complications in bilateral DMFs is an open question. The purpose of this study is to assess the complication rate in patients suffering from bilateral DMF treated either using non-rigid fixation on both fracture sides or a combination of rigid fixation on one side and non-rigid fixation on the other side.
Patients who sustain a fracture of the lower jaw are typically treated by wiring the teeth together or using small titanium plates and screws to fix the fracture. With either technique the upper and lower teeth are held together to ensure that the fracture is held in the correct position during healing (for closed reduction) or while the plate and screws are applied (for open reduction). The teeth can be held together using Erich arch bars which are a type of braces that are temporarily wired to the existing teeth. These stay in place for 6 weeks until the fracture has healed even though the patient is able to open his mouth immediately after the surgery is complete. The alternative to the traditional Erich arch bars is a relatively new type of arch bar (Stryker Hybrid) that is screwed to the jaw bone rather than wired to the teeth. The purpose of this study is to compare the two types of arch bars in terms of the speed with which they can be applied as well as any difference in fracture healing
Introduction After a mandibular fracture where bone has been lost, a number of complications and challenges are presented in trying to solve them. These defects are mainly classified into two groups: functional and cosmetic. The functional defects are incompetence of the lower lip, salivary incontinence, severe difficulty chewing and swallowing, temporomandibular joint disorders and difficulty in pronouncing words. Esthetically facial asymmetry is produced with collapse of the affected side. Unreconstructed jaw retrusion and tends to offset the affected side, there is a change in mandibular movements, which, previous vertical movements are replaced by oblique or diagonal movements controlled by a single temporomandibular joint. It also presents a limitation in motility and lingual force, besides proprioception disorder left by the inferior alveolar nerve The loss of bone in mandibular fractures, is one of the great challenges facing maxillofacial surgery and unfortunately increasingly common. That's why they have done and are still doing research for the development of biomaterials, all with the purpose of trying to solve this problem by offering the patient better results than those obtained in the past, restoring both function and facial aesthetics according to each case
