Abstract

Patient: A 67-year-old male underwent resection and postoperative radiotherapy for left maxillary sinus cancer. Mandibular trismus remained as a late disorder of radiotherapy, and he complained of masticatory dysfunction. In order to obtain sufficient space between the upper and lower teeth, the occlusal plane and occlusal vertical dimension were corrected by pulpectomy and crown prosthesis, and then a new maxillary denture for the defected jaw and a mandibular removable partial denture were fabricated.

Discussion: In this case, space between the upper and lower teeth could be secured by fabricating the new maxillary denture and the new mandibular removable partial denture after correcting the occlusal plane and occlusal vertical dimension, thus improving masticatory function and obtaining good results.

Conclusion: In patients with mandibular trismus, performing appropriate preprosthetic treatment before fabricating removable dentures is effective for restoring masticatory function and thereby improving patient satisfaction.
