Definitive guiding flange prosthesis: A definitive approach in segmental mandibulectomy defect

Area of Science:

• Oral and Maxillofacial Surgery
• Prosthodontics
• Biomaterials Engineering

Background:

• Mandibular discontinuity defects after segmental mandibulectomy pose significant challenges for oral rehabilitation.
• Restoring function and aesthetics following extensive mandibular resection requires innovative prosthetic solutions.

Observation:

• A case report details the prosthodontic rehabilitation of a patient with a segmental mandibulectomy.
• The patient presented with a significant mandibular defect impacting occlusion and mandibular guidance.

Findings:

• A definitive mandibular guidance prosthesis featuring a metal guiding flange and acrylic teeth was employed.
• This prosthesis successfully stabilized the occlusion and corrected the mandibular deviation on the resected side.

Implications:

• This prosthetic approach offers a viable solution for stabilizing occlusion and improving function in patients with mandibular defects.
• The use of a metal guide flange prosthesis demonstrates effective management of post-mandibulectomy challenges.
