ABSTRACT

Retention, stability and support are the fundamental prerequisites, which determine the success of complete denture. Residual ridge resorption is the reduction in size of the bony ridge under the mucoperiosteum. Fabricating dentures on atrophic ridges has always been an ordeal for the clinicians. Combination of reduced bone volume and increased inter arch space makes it difficult to achieve support, stability and retention due to mechanical disadvantage. Dentures in such cases inadvertently result in increased thickness and weight of denture, resulting in compromised retention and stability. This in turn overloads the underlying supporting tissues exacerbating ridge resorption. Hence, in order to break this vicious cycle, the weight of the prosthesis needs to be reduced which can be achieved by making hollow prosthesis. The advantage of a hollow denture is the reduction of excessive weight of acrylic resin, which replaces lost alveolar ridge in the in the inter-ridge space of the denture wearer. This case describes a simple yet novel way of fabricating hollow maxillary complete denture using Dental Plaster & Pumice- Sugar syrup paste.
