Class III mandibular resection due to surgical treatment of jaw tumor produces a discontinuity in the mandible which is severely incapacitating to the patient. It leads to a deviation and rotation of the mandible which depends on the amount of tissues resected the manner of surgical site closure, loss of proprioceptive sense of occlusion, the presence, and condition of teeth, and the time of initiation of prosthodontic therapy. These put together makes the task of prosthodontic rehabilitation quite arduous. Guide flange prosthesis is a comparatively simple and cost-effective method of restoring the esthetics and function to an acceptable level. This clinical report describes an innovative and simplified approach to impression making (sectional two-step impression) to minimize trauma to the underlying and circumoral fragile tissues postsurgery, and to the fabrication of buccal guide flange (wrought wire supported and reinforced guide flange) for prosthetic rehabilitation of a patient with Class III mandibular resection.
因颌骨肿瘤手术治疗而进行的Ⅲ类下颌骨切除术会导致下颌骨连续性中断，这对患者造成严重功能障碍。它会导致下颌骨偏斜和旋转，这取决于切除组织的量、手术部位闭合的方式、咬合本体感觉丧失、牙齿的存在及状况以及修复治疗开始的时间。这些因素综合起来使得修复治疗的任务相当艰巨。导板义齿是一种相对简单且经济有效的方法，可将美观和功能恢复到可接受的水平。本临床报告描述了一种创新且简化的取模方法（分段两步取模），以尽量减少术后对下方及口周脆弱组织的创伤，以及为一名Ⅲ类下颌骨切除患者制作颊侧导板（锻丝支撑和加强导板）用于修复治疗。
