- Maxillary Arch: Completely edentulous maxillary arch restored with a conventional full acrylic based upper complete denture.
- Mandibular Arch: Dentate, partial or full edentulous mandibular arch. Partial or full edentulous arch may be restored with a stable complete, partial or implant supported denture. (Mandibular dentures are not used for assessments or measures).
- Maxillary dentures must be considered to be moderately well-fitting at the screening visit. (Kapur Index, Olshan Modification: retention score >2, stability score >2).
- Maxillary dentures must be considered to be well-made based on design and construction criteria specified in the protocol.
Exclusion criteria:
- Women who are breast-feeding, are known to be pregnant or who are intending to become pregnant over the duration of the study.
- Known or suspected intolerance or hypersensitivity to the study materials (or closely related compounds) or any of their stated ingredients.

- Recent history (within the last year) of alcohol or other substance abuse.
- Current or relevant history of any serious, severe or unstable physical or psychiatric illness or any other medical condition (e.g. Diabetes Mellitus) that would make the participant unlikely to fully complete the study or any that increases the risk to the participant or undermines the data validity.
- Implanted with a cardiac pacemaker.
- Daily doses of medication (example Antibiotics, Inhaled steroids etc.) that might interfere with ability to perform the study according to protocol or might affect the efficacy assessments (as determined by the Investigator/ Examiner).
- Any clinically significant or relevant oral abnormality that, in the opinion of the Investigator, could affect the participant’s participation in the study.
- Any pre-existing oral irritations.
- Any recent (within 30 days) gingival /oral surgery.
