Restoring Occlusal Vertical Dimension of Kennedy Class I Partially Edentulous Mandibular Arch Using an Overlay Cobalt-Chromium Partial Denture and Thin Acrylic Veneers

Reduced occlusal vertical dimension due to severe tooth surface loss poses significant functional and aesthetic impacts to the patient. Extensive dental procedures to restore the occlusion and aesthetics is usually a challenge to the treating dentist. Overlay removable partial denture can be used as the simpler treatment modalities to treat moderate to severe tooth surface loss. This case study reported the fabrication of a lower partial cobalt-chromium overlay denture to restore the occlusal vertical dimension on a 78 year-old lady with Kennedy Class I partially edentulous with severe lower anterior tooth surface loss. Thin layer of acrylic tooth veneers was added to the labial surface of the overlay denture to improve the aesthetics. This solution was functionally acceptable and met the need and demand of the patient.
