Brief Summary

Dental services for large sectors of the population of the Western Cape (WC) Province of South Africa (SA) has been, and continues to be, limited to low-cost treatment options and emergency services, such as extractions at public health clinics. Replacement of missing teeth for the disadvantaged majority of the population is provided almost exclusively at the dental teaching institutions. Loss of teeth in the WC Province is, as elsewhere, the result of disease and the lack of restorative care and then having these replaced by a removable partial denture, if the patient can afford it Null Hypothesis: The daily functional needs and quality of life of partially dentate adult patients with a reduced posterior dental arch and /or a Shortened Dental Arch (SDA) will not be satisfied nor improved by replacing the posterior teeth with a removable prosthesis.

Study Arms (2)

Removable partial denture Group

EXPERIMENTAL

Patients with a reduced posterior dental arch will be randomized into one of 2 Groups Group A will receive a removable partial denture prosthesis

Device: Removable partial denture (Chrome Cobalt Distal extension)

Reduced Posterior Dental Arch Group

ACTIVE COMPARATOR

Patients with a reduced posterior dental arch and not receiving any Intervention will be compared to the removable partial denture group

Other: A reduced posterior dental arch

Interventions

For Group A: a distal extension removable denture will be constructed for patients with a reduced posterior dental arch

Also known as: Chrome Cobalt Distal extension denture for Group A patients
Removable partial denture Group

For Group B: Patients with a reduced posterior dental arch will not be provided with a removable denture and will be compared to patients in Group A

Also known as: No intervention for Group B patients
Reduced Posterior Dental Arch Group
