Various techniques have been employed from time to time to achieve maxillomamdibular fixation. Although arch bars provide an effective and versatile means of maxillomandibular fixation, their use is not without shortcomings. However the introduction of intermaxillary fixation screws (IMF) has eliminated many of these issues of arch bars. The aim of the present study was to compare the advantages and disadvantages of intermaxillary fixation screws over the Erich arch bars in mandibular fractures.
Sixty dentulous patients who reported to Department of Oral and Maxillofacial Surgery, Al-Ameen Dental College and Hospital, Bijapur with mandibular fractures and required intermaxillary fixation as a part of treatment plan followd by open reduction and internal fixation under GA were selected and randomly divided into 2 groups of 30 patients each that is Group A and Group B. Group A included patients who received intermaxillary fixation with Erich arch bars. Group B includes patients who received intermaxillary fixation with IMF Screws. The parameters compared in both the groups included, surgical time taken, gloves perforation, post-operative occlusion, IMF stability, oral hygiene, patient acceptance and comfort and non-vitality characteristics.
The average surgical time taken and gloves perforations were more in Group A,the patient acceptance and oral hygiene was better in Group B, there was not much statistically significant difference in postoperative occlusion and IMF stability in both groups. Accidental root perforation was the only limitation of IMF screws.
Intermaxillary fixation with IMF screws is more efficacious compared to Erich arch bars in the treatment of mandibular fractures.
为实现上下颌骨固定，人们不时采用各种技术。尽管牙弓夹板提供了一种有效且通用的上下颌骨固定方法，但其使用并非没有缺点。然而，颌间固定螺钉（IMF）的引入消除了牙弓夹板的许多问题。本研究的目的是比较颌间固定螺钉与 Erich 牙弓夹板在下颌骨骨折治疗中的优缺点。
选取 60 例到比贾布尔 Al-Ameen 牙科学院和医院口腔颌面外科就诊的下颌骨骨折患者，他们需要进行颌间固定作为治疗计划的一部分，随后在全身麻醉下进行切开复位内固定。将患者随机分为两组，每组 30 例，即 A 组和 B 组。A 组患者接受 Erich 牙弓夹板颌间固定。B 组患者接受颌间固定螺钉固定。两组比较的参数包括手术时间、手套穿孔情况、术后咬合、颌间固定稳定性、口腔卫生、患者接受度与舒适度以及无活力特征。
A 组的平均手术时间和手套穿孔次数更多，B 组的患者接受度和口腔卫生状况更好，两组术后咬合和颌间固定稳定性在统计学上无显著差异。意外牙根穿孔是颌间固定螺钉的唯一局限性。
在治疗下颌骨骨折方面，与 Erich 牙弓夹板相比，颌间固定螺钉更为有效。
