Aim: Fabrication of lightweight dentures for hemimandibulectomy patients. Background: The discontinuity in case of a mandibular resection leads to decreased stability, retention and support of a prosthesis. The weight of the prosthesis is one of the primary dislocating factors because it often acts as a cantilever. To decrease the leverage action, reduction in the weight of the prosthesis is mandatory. Case description: In this case report the use of expanded polysterene (thermocol) has been done to increase the stability of the prosthesis, thereby, increasing the comfort and acceptance of the patient. Conclusion: This case report gives an insight as to how a lightweight material can be added to reduce the weight of denture, without compromising is integrity and function. Clinical significance: Lightweight materials such as expanded polystyrene (thermocol) allow control of spacer thickness to reduce the weight of the denture without compromising the integrity of the denture.
