Treatment plan is patient–specific and varies according to the history given by the patient. Xerostomia is a condition in which salivary secretion reduces and patient usually shows dry mouth or existence of thick ropy saliva. It can be a result of various causes but is mainly seen in geriatric population as a side effect of the drugs being consumed for whatsoever medical reasons. Residual ridge resorption is a chronic process, and severely resorbed ridges can be seen in large numbers in the geriatric population. This leads to an increased interridge space which thereby increases the weight of the denture, and transfers detrimental forces on the underlying ridges causing further resorption. This article aims to provide a method of fabricating salivary reservoir mandibular dentures in patients suffering from xerostomia, and hollow maxillary dentures in patients with increased interridge distance.
