A 70-year-old patient with reconstructed mandibulectomy presented to our clinic with a complaint of denture instability. Due to left mandibular gingival cancer, she had received segmental resection of the left mandible and reconstruction with the fibula. An intraoral examination revealed few intermaxillary occlusal contacts due to the deviation of the mandibular dental arch. A mandibular denture and maxillary prosthesis with palatal ramp were fabricated to provide sufficient occlusal contacts and bilateral balanced occlusion.
Regardless of reconstruction, a careful case history, combined with meticulous clinical evaluation was demanded in this mandibulectomy patient. The ramp on maxillary prosthesis could provide not only proper occlusal scheme but also stability of mandibular denture.
To improve masticatory function in a reconstructed mandibulectomy patient with deviated mandibular movement and disagreement of occlusion, maxillary prosthesis with palatal ramp was effective.
一名70岁接受过下颌骨重建切除术的患者因义齿不稳定前来我院就诊。由于左侧下颌牙龈癌，她接受了左侧下颌骨节段性切除并用腓骨进行重建。口腔检查发现，由于下颌牙弓偏移，上下颌间咬合接触较少。制作了一副下颌义齿和带有腭隆突的上颌修复体，以提供足够的咬合接触和双侧平衡咬合。
对于该下颌骨切除患者，无论是否进行了重建，都需要仔细询问病史并结合细致的临床评估。上颌修复体上的腭隆突不仅可以提供合适的咬合方案，还能增强下颌义齿的稳定性。
对于下颌运动偏斜且咬合不协调的下颌骨重建切除患者，带有腭隆突的上颌修复体在改善咀嚼功能方面是有效的。
