Area of Science:

  • Dentistry
  • Prosthodontics
  • Oral Surgery

Background:

  • Excessive lingual undercuts post-mandibulectomy pose rare but significant prosthodontic challenges.
  • Restoring function and aesthetics in such cases requires specialized treatment approaches.

Purpose of the Study:

  • To describe the fabrication of a hinged removable mandibular complete denture.
  • To address the unique challenges posed by excessive lingual undercuts after mandibulectomy and reconstruction.

Main Methods:

  • Utilized a sectional impression tray technique for accurate mold capture.
  • Incorporated a custom-made hinge mechanism for enhanced prosthesis function.
  • Detailed clinical and laboratory procedures for prosthetic fabrication.

Main Results:

  • Successfully fabricated a hinged removable mandibular denture prosthesis.
  • The described technique effectively managed excessive lingual undercuts.
  • Provided lip support, improved articulation, reduced drooling, and enhanced aesthetics.

Conclusions:

  • Hinged removable mandibular dentures offer a viable solution for patients with excessive lingual undercuts.
  • The sectional impression technique and custom hinge are effective for complex cases.
  • This approach can significantly improve the quality of life for patients post-mandibulectomy.
