An innovative design of 2-piece saliva reservoir using precision attachment: a case report.

Standard head and neck radiotherapy results in serious, often irreversible damage to the major and minor salivary gland tissues. The resultant profound hypo-salivation leads to serious oral health and functional problems that seriously affect oral health-related quality of life. Intra-oral devices with reservoirs have been developed that allow the release of saliva substitute into the mouth.
