A case of recovery from masticatory disorders in a patient following mandibular resection by inserting removable partial dentures

Abstract

Patient: The patient, a 59-year-old man, came to our hospital with a chief complaint of missing teeth and difficulty chewing. The patient was diagnosed with masticatory disorder due to partial loss of the mandibular dentition following mandibular resection of mandibular gingival cancer. We fabricated new dentures and restored stable occlusion to restore masticatory function and improve masticatory disorders.

Discussion: Functional adjustment of the dentition improved the occlusal contact area and increased the occlusion force, and the chewing cycle stabilized. The improvement was verified by chewing ability tests and chewing evaluation using Hirai’s food intake survey.

Conclusion: Proper denture placement in patients with jaw defects is thought to ensure a stable occlusal relationship, improve occlusal force, and restore masticatory ability, thereby contributing to the improvement of masticatory disorders.
