Guide flange is given to patients who have undergone surgical hemi/segmental/subtotal mandibulectomy due to various reasons (leading cause being squamous cell carcinoma), with resultant mandibular deviation. If procedures such as secondary osseous grafting are planned, the clinician has to wait for healing of the graft, lesion, or radiotherapeutic effects to abate. Only after the healing of the graft, a definitive prosthesis can be planned. During this time lag, prosthesis must be given to the patient to correct mandibular deviation on account of unilateral muscle pull. Furthermore, in certain cases, a definitive prosthesis has to be put on hold due to failure of bone grafting or when the patient is not willing for a second surgery. This report describes the fabrication of such a mandibular guide flange prosthesis.
对于因各种原因(主要原因是鳞状细胞癌)接受了半侧/节段性/次全下颌骨切除术且导致下颌骨偏斜的患者,会给予导向翼缘。如果计划进行二次骨移植等手术,临床医生必须等待移植骨、病变或放射治疗效果愈合消退。只有在移植骨愈合后,才能计划制作最终假体。在此时间间隔内,必须给患者佩戴假体以纠正由于单侧肌肉牵拉导致的下颌骨偏斜。此外,在某些情况下,由于骨移植失败或患者不愿意接受二次手术,最终假体不得不搁置。本报告描述了这种下颌导向翼缘假体的制作。
