Cast Partial Dentures: Distal Extension Base

Distal extension cast partial dentures remain one of the most challenging yet indispensable treatment modalities in prosthodontic rehabilitation. Their success depends on a thorough understanding of biomechanics, meticulous treatment planning, precise clinical procedures, and thoughtful prosthesis design.This dissertation presents a comprehensive review of the principles and practices involved in the management of Kennedy Class I and Class II partially edentulous arches. It explores the biological and mechanical considerations unique to distal extension prostheses, discusses various impression techniques and design concepts, and highlights contemporary advancements that have improved clinical outcomes.By integrating foundational knowledge with current evidence, this work serves as a valuable resource for undergraduate and postgraduate students, clinicians, and researchers seeking to enhance their understanding of distal extension cast partial dentures and their role in restoring function, aesthetics, and patient comfort.
