Prosthetic Rehabilitation in Oral Cancer Patients: A Pathological and Functional Perspective

Abstract

Oral cancer remains a major contributor to global morbidity, particularly in regions with high prevalence of tobacco and alcohol consumption. Surgical management of oral malignancies often results in extensive anatomical defects that compromise essential oral functions such as mastication, speech, and swallowing, along with facial aesthetics. Prosthetic rehabilitation plays a pivotal role in restoring these lost functions and improving the overall quality of life of affected individuals. This review critically examines prosthetic rehabilitation from both pathological and functional perspectives, emphasizing the relationship between disease progression, treatment modalities, and rehabilitative outcomes.

The pathological alterations caused by tumor invasion and therapeutic interventions such as radiotherapy and chemotherapy significantly influence prosthetic planning and success. Various prosthetic options, including obturators, removable dentures, and implant-supported prostheses, have demonstrated varying degrees of effectiveness depending on patient-specific factors. Functional outcomes such as speech intelligibility, masticatory efficiency, and swallowing capacity show measurable improvement following rehabilitation, although complete restoration is rarely achieved. Additionally, psychological well-being and social reintegration are strongly linked to successful prosthetic outcomes.

Despite technological advancements, several challenges persist, including compromised tissue quality, reduced salivary flow, and implant failure in irradiated bone. Emerging innovations such as digital workflows, 3D printing, and biomaterial engineering offer promising avenues for enhancing rehabilitation outcomes. This review underscores the necessity of a multidisciplinary approach to optimize functional recovery and improve long-term quality of life in oral cancer patients.
