Abstract

Treatment of compound alveolar bone fracture consists of reduction and fixation with wound closure of soft tissue laceration. For the proper reduction and fixation, interosseous wiring or splinting of the involved teeth are applied during about 4 weeks. But wound infection around the fracture site may be occurred, because of the presence of devitalized tissues(pulp, bone and soft tissue), residual hematoma and anergy effect of trauma stress. The wound infection results in bone resorption, pulp degeneration and necrosis,wound dehiscence and soft tissue necrosis around the fracture site. Therefore, if the infection will be expected,early proper drainage should be established via the fracture site and root canal of the luxated teeth. The authors treated two cases of compound alveolar bone fracture by the rubber drainage in the fracture site and the endodontic drainage by open canal of the luxated teeth, with the usual reduction and fixation by use of arch bar and resin. The prognosis was more favorable without wound infection, bone resorption, teeth mobility and specific root resorption.
