Abstract:

BACKGROUND: Mandibular fractures often harm patient’s work and life. Intermaxillary traction nail with small/mini-titanium plate, relative to traditional dental arch splint combined with small/mini titanium plate treatment alone, is characterized by short treatment time and good fixation effect, which can improve the maxillofacial dysfunction and promote the early completion of the treatment.
OBJECTIVE: To explore the curative effect of intermaxillary traction nail with mini-titanium plate versus dental arch splint combined with small/mini-titanium plate on mandibular fractures
METHODS: Ninety cases of mandibular fractures hospitalized at the Department of Oral and Maxillofacial Surgery, Stomatological Hospital of Southwest Medical University in China from July 2011 to May 2015 were enrolled in this study. These patients were equivalently randomized into control group subjected to dental arch splint combined with small/mini-titanium plate and observation group subjected to intermaxillary traction nail with mini-titanium plate. All the patients were followed up for 4-6 months. Curative effects, including excellent and good rate and total efficiency, were compared between the two groups. Maxillofacial function and incidence of adverse reactions were observed and recorded, respectively, to analyze the experimental data and assess their clinical values.
RESULTS AND CONCLUSION: The total efficiency and the maxillofacial 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 intermaxillary traction nail combined with small/mini-titanium plate mini titanium plate and mini titanium plate was good, safe and reliable.
