Hollow Denture & Artificial Saliva:Prosthodontic Management of Xerostomia & Resorbed Ridges - A Case Report
![Page 2: Artificial Salivary dentures with palatal reservoir](https://reader036.vdocuments.us/reader036/viewer/2022062523/577cce251a28ab9e788d7213/html5/thumbnails/2.jpg)
Introduction
Resorbed Ridges as well as Xerostomia are common clinical cases found.
The weight of a denture is often a dislodging factor . Hence, a light weight denture with salivary substitutes is required for better retention in such situations.

What is Xerostomia & Resorbed Ridge
Xerostomia is defined as dryness of the mouth due to the lack of normal secretion of saliva.
Resorbed Ridge is defined as the the diminished quality and quantity of bone that remains after the removal of the teeth.

Patient Instructions & Recall Visits
Demonstrate to the patient how to inject saliva substitute through the hole in both Maxillary and mandibular reservoir
by using a 5 Ml disposable syringe and needle. Provide a treatment record card and ask the patient to note
every time the reservoir is filled, the quantity of substitute, and the time till the reservoir is empty.
Patient is instructed to clean the denture using 2% sodium hypochlorite
![Page 22: Artificial Salivary dentures with palatal reservoir](https://reader036.vdocuments.us/reader036/viewer/2022062523/577cce251a28ab9e788d7213/html5/thumbnails/22.jpg)
Make a 24 hr. first recall appointment Make a 1-week recall appointment. After 1 week, evaluate the record and
calculate the average duration of flow. The duration of flow provided by artificial
saliva reservoirs should range from 2 to 5 hours.
Increase or reduce the size of the hole to adjust the flow rate.
