  Purpose

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 classic Shortened Dental Arch (SDA) will not be satisfied nor improved by replacing the molars with a removable prosthesis.

Primary Outcome Measures:
  • Patient satisfaction [ Time Frame: 6 Months ] [ Designated as safety issue: No ]

    Two different tools will b used to assess primary outcomes

    1. Oral Indicator Dental Profile (OIDP)
    2. Global Visual Analogue Scale


Secondary Outcome Measures:
  • Success of treatment intervention [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    Failure of intervention or patient unhappy with treatment prescribed


Estimated Enrollment: 2
Study Start Date: October 2012
Estimated Study Completion Date: December 2014
Estimated Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Removable partial denture Group
Patients with a classic SDA will be randomized into one of 2 Groups Group A will receive a removable partial denture
 Device: Removable partial denture (Chrome Cobalt Distal)
For Group A: a distal extension removable denture will be constructed for patients with a classic SDA
Other Name: Chrome Cobalt Distal extension denture for Group A patients
Active Comparator: Shortened Dental Arch Group
Patients with a Classic SDA and not receiving any Intervention will be compared to the removable partial denture group
 Other: A classic SDA
For Group B: Patients with a classic SDA will not be provided with a removable denture and will compared to patients in Group A
Other Name: No intervention for Group B patients

Detailed Description:

The aim of this research is to determine whether the daily functional needs and the quality of life of partially dentate adult patients with a classic SDA will be satisfied and improved without having the molars replaced with a removable prosthesis, as compared to having the use of such prosthesis.

Objectives: To conduct a randomized controlled trial amongst partially dentate adult patients with a classic SDA dentition (20 occluding teeth, including all incisors, canines and premolars) and where these patients will be randomly assigned to one of two groups: one group would be provided with a metal- based removable partial denture (RPD) to replace the molars bilaterally, the other will receive no treatment.

Daily functioning ability and patient satisfaction between the groups (with/without RPD) would then be compared.
