Locking plates and locking screws for management of mandibular fractures.
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 17, Issue 2
Abstract
Introduction: Assaults were common cause for mandibular and zygomatic complex fractures. When trauma is reported from large industry urban areas with high unemployment, lower facial trauma from alterations are more common. By and large the therapeutic goal of any fracture management is to restore original anatomic form and function as soon as possible without any morbidity. Ideally this should be accomplished at the earliest with the least patient discomfort. Aim: To evaluate the usefulness of 2.0mm Locking plate/screw system on mandibular fracture patients, who reported to Department of Dental surgery, Government Dharmapuri Medical College, Dharmapuri, Tamilnadu, India. Material and Methods: Thirty cases of fracture mandible of age group 20 to 56 years were taken up for study. They were treated by open reduction and internal fixation through an intraoral approach with 2.0mm Stainless steel locking plates and screw system for osteosythesis of mandible. The screw holes in the bone plate were engineered to accept either screws that lock to it by a second thread under the head of the screw or standard non locking screws. Parameters such as ease of technique, occlusal stability, inter incisal opening, signs of infections and functional stability are evaluated. Results: Thirty patients with 42 fracture mandible sites were treated with 54 locking plates and screws and observed for 12 weeks. All patients showed normal functions of jaws like mouth opening, chewing and speaking. Six patients complained of pain during mastication which was managed with analgesics. Only one patient needed intermaxillary fixation wiring. Conclusion: Locking plates and screw system not only fulfilled the treatment goals of adequate immobilization, fixation & stabilization of mandible fractures, offer greater stability, easy to adapt, do not require intimate contact with bone there by reduces the disturbance to the cortical bone blood supply enhances the osteosynthesis at the fracture site.
