Surgical resection of the lower jaw due to the presence of a benign or malignant tumor is the most frequent cause of mandibular deviation. Location and extent of the tumor decide the surgical modality of mandibulectomy to be performed. The clinician must wait for an adequate span of time for completion of the healing and acceptance of the osseous graft before considering a definitive prosthesis. During the inceptive healing period, prosthodontic intervention is of utmost priority for preventing the mandibular deviation. A corrective appliance termed "guide flange prosthesis (GFP)" is indicated to limit this clinical manifestation. The basic intention of rehabilitation is to train the mandibular muscles and to re-establish an acceptable occlusal relationship so that the patient can adequately control the opening and closing movements. This case series describes early prosthodontic management of three patients who had undergone hemimandibulectomy, with different techniques of fabrication of a GFP. The three techniques described consist of two conventional methods of fabrication while the third technique is a new innovative approach.
由于良性或恶性肿瘤的存在而进行下颌骨切除术是下颌骨偏斜最常见的原因。肿瘤的位置和范围决定了要进行的下颌骨部分切除术的手术方式。临床医生必须等待足够的时间，让骨移植完全愈合和接受，然后再考虑进行最终修复体。在初始愈合期间，修复体介入对于预防下颌骨偏斜至关重要。需要使用一种称为“导板义齿（GFP）”的矫正装置来限制这种临床表现。康复的基本目的是训练下颌肌肉并重新建立可接受的咬合关系，以便患者能够充分控制开口和闭合运动。本病例系列描述了三名下颌骨部分切除术患者的早期修复体管理，这些患者采用了不同的 GFP 制作技术。所描述的三种技术包括两种常规制作方法，而第三种技术是一种新的创新方法。
