The purpose of the treatment of mandibular fractures is to restore proper dental occlusion and stable temporomandibular joint movement, as well as the reduction of the displaced fracture. Consideration must be given to the selection of the most appropriate surgical and rehabilitation methods in such patients. Typical surgical methods for the treatment of mandibular fractures include the arch bar method or plating at the location of the fracture combined with fixing the mandible to the maxilla using the arch bar method. However arch bars and circumdental wires, which require teeth for fixation, damage teeth and periodontal tissue, and tend to be uncomfortable for patients during the fixation period. Moreover, daily maintenance of oral hygiene is difficult for patients with an arch bar. Surgeons are also exposed to the risk of blood-transmitted diseases through skin punctures by wires when affixing these devices. For these reasons, we chose to study the potential of the MMFS method, which is thought to lessen all of the following problems: tissue damage, operating time, patient discomfort, and possible exposure to percutaneous infectious disease due to puncture of gloves and skin by the wires. We demonstrated the utility of the MMFS method in the present study.
下颌骨骨折治疗的目的是恢复正常的牙合关系和稳定的颞下颌关节运动，以及复位移位的骨折。对于此类患者，必须考虑选择最合适的手术和康复方法。治疗下颌骨骨折的典型手术方法包括牙弓夹板法或在骨折部位进行钢板固定，并结合使用牙弓夹板法将下颌骨与上颌骨固定。然而，牙弓夹板和环绕牙的钢丝需要牙齿进行固定，会损伤牙齿和牙周组织，并且在固定期间患者往往会感到不适。此外，佩戴牙弓夹板的患者难以进行日常口腔卫生维护。在固定这些装置时，外科医生还面临因钢丝刺破皮肤而感染血液传播疾病的风险。出于这些原因，我们选择研究MMFS方法的潜力，该方法被认为可以减轻以下所有问题：组织损伤、手术时间、患者不适以及因钢丝刺破手套和皮肤而可能接触经皮感染性疾病。我们在本研究中证明了MMFS方法的实用性。
