指示:

下颌骨损伤:

下颌骨粉碎性骨折,不稳定性骨折,感染性骨不连及骨缺损。

下颌骨重建:

第一次或第二次重建,用于移植骨或缺陷的离解骨块(如果第一次手术没有植骨,重建板只有确保承担有限的时间内,必须第二骨移植物操作支持重建馅饼)。

特点和优点:

斜排重建钢板是一种专门设计用于术中固定,改善特定区域应力集中现象和疲劳强度。

一孔选择两种螺钉锁定颌面部重建解剖钢板可实现锁定和非锁定两种固定方法。锁定螺钉固定骨块的同时将钢板牢牢锁住,类似内置式外固定支架。非锁定螺钉可作角压固定。

匹配的螺丝:

φ2.4毫米自攻螺钉

φ2.4毫米锁紧螺钉

匹配的仪器:

医用钻头φ1.9*57*82mm

十字头螺丝刀:SW0.5*2.8*95mm

下颌骨作为面部重要的美容器官,其形态在面部美学中起着重要的作用。创伤、感染、肿瘤切除等因素均可引起缺损。下颌骨缺损不仅影响患者的外观,还会引起咀嚼、吞咽、语言等功能的异常。理想的下颌骨重建不仅要实现下颌骨的连续性和完整性,恢复面部外观,而且要为术后咀嚼、吞咽、说话等生理功能的恢复提供基础条件。

下颌骨缺损的原因

肿瘤治疗:成釉细胞瘤、黏液瘤、癌、肉瘤。

撕脱性创伤:最常见的起因是高速伤害,如枪支、工业事故和偶尔的机动车碰撞。

炎症或感染性疾病

重建的目标

1.恢复脸的下三分之一和下颌骨的原始形状

2.维持下颌骨的连续性,恢复下颌骨与周围软组织的空间位置关系

3.恢复良好的咀嚼、吞咽和说话功能

4.保持足够的气道

下颌骨缺损的显微重建有四种类型。创伤and tumor resection of the mandible may affect appearance and lead to functional deficits such as malocclusion due to unilateral muscle injury.In order to repair the appearance defect and reconstruct the function, many surgical methods have been developed, and the difficulty of the successful reconstruction of the mandible lies in the selection of the best method.Because of the complexity of mandibular defect, a set of simple, practical and generally accepted systematic classification and treatment methods is still blank.Schultz et al. demonstrated a new simplified classification method and the corresponding method for the reconstruction and repair of the mandible through practice, which was published in the latest journal of PRS.This classification focuses on vascular integrity in the recipient area, with a view to accurately repairing complex mandibular defects by microsurgical means.The method is first divided into four types according to the complexity of reconstructive surgery.The lower midline of the mandible was the boundary. Type 1 had a unilateral defect that did not involve the mandibular Angle, type 2 had a unilateral defect involving the ipsilateral mandibular Angle, type 3 had a bilateral defect involving neither side of the mandibular Angle, and type 4 had a bilateral defect involving the unilateral or bilateral mandibular Angle.Each type is further divided into type A (applicable) and type B (not applicable) according to whether the ipsilateral vessels are suitable for anastomosis. Type B requires anastomosis of the contralateral cervical vessels.For type 2 cases, it is necessary to indicate whether the condylar process is involved in order to decide which graft material to use: Unilateral condylar involvement is 2AC/BC, and no condylar involvement is 2A/B.Based on the above classification and considering the skin defect, the length of the mandibular defect, the need for dentures, and other special circumstances, the surgeon further determines the type of free bone flap to be used.

预成型重建钢板适用于口腔颌面外科、创伤和重建外科。这包括初次下颌骨重建,粉碎性骨折和临时桥接等待延迟的二次重建,包括无牙和/或萎缩的下颌骨骨折,以及不稳定骨折。患者受益-通过寻求达到满意的美容效果和减少手术时间。下颌骨患者专用钢板消除钢板弯曲引起的机械应力。
