Abstract：BACKGROUND:Mandibular fractures often harm patient’s work and life. Intermaxilary traction nail with smal/mini-titanium plate, relative to traditional dental arch splint combined with smal/mini titanium plate treatment alone, is characterized by short treatment time and good fixation effect, which can improve the maxilofacial dysfunction and promote the early completion of the treatment. <br> OBJECTIVE:To explore the curative effect of intermaxilary traction nail with mini-titanium plateversus dental arch splint combined with smal/mini-titanium plate on mandibular fractures <br> METHODS:Ninety cases of mandibular fractures hospitalized at the Department of Oral and Maxilofacial Surgery, Stomatological Hospital of Southwest Medical University in China from July 2011 to May 2015 were enroled in this study. These patients were equivalently randomized into control group subjected to dental arch splint combined with smal/mini-titanium plate and observation group subjected to intermaxilary traction nail with mini-titanium plate. Al the patients were folowed up for 4-6 months. Curative effects, including excelent and good rate and total efficiency, were compared between the two groups. Maxilofacial function and incidence of adverse reactions were observed and recorded, respectively, to analyze the experimental data and assess their clinical values. <br> RESULTS AND CONCLUSION:The total efficiency and the maxilofacial function were significantly better in the observation group than the control group (P < 0.05). Plaque and debris index was increased significantly in the control group compared with the experimental group before and after treatment (P < 0.05). The gingival index had no significant changes in the observation, but it was increased significantly in the control group before and after treatment (P< 0.05). The number of cases of adverse reactions was significantly less in the experimental group than the control group (P < 0.05). These results show that the effect of internal fixation with intermaxilary traction nail combined with smal/mini-titanium plate mini titanium plate and mini titanium plate was good, safe and reliable.
