Patients will be randomised to receive CAD/CAM metallic removable partial denture (RPD) followed by Conventional metallic RPD (Group A), or the opposite sequence (Group B), with a 3-month wear duration for each denture and washout period for one week. Patients will be recalled at base line and 3 months following prosthetic insertion to evaluate Oral health related quality of life. It is hypothesized that removable partial dentures with CAD/CAM metallic RPD frameworks would improve Oral health related quality of life than those with Conventional metallic RPD frameworks.

Opposing dentition is fully intact or restored.
Sufficient inter-arch space.
Angle's class I maxilla-mandibular relationship.
Periodontal affection of the abutment teeth.
