Summary
Implant-supported removable partial dentures (ISRPDs) offer cost-effective treatment for edentulous patients, particularly when considering oral health impact. The cost-effectiveness hinges on willingness to pay per improved oral health outcome.
Area of Science:
- Dental Prosthetics
- Health Economics
- Oral Health Outcomes
Background:
- Conventional removable partial dentures (RPDs) and implant-supported RPDs (ISRPDs) are treatment options for patients with extensive tooth loss.
- Assessing the economic value of ISRPDs compared to conventional RPDs is crucial for clinical decision-making and resource allocation.
Purpose of the Study:
- To perform a cost-effectiveness analysis comparing conventional RPDs and ISRPDs.
- To evaluate these treatments for patients with an edentulous maxilla and a free-ending mandibular situation.
Main Methods:
- A cost-effectiveness analysis was conducted on 30 subjects receiving either RPDs or ISRPDs.
- Treatment costs were calculated using opportunity costs and national tariffs.
- Treatment effects were measured using the Oral Health Impact Profile (OHIP-NL49), Mixing Ability Index (MAI), and quality-adjusted life-years (QALYs).
Main Results:
- Total opportunity costs were €981 for RPDs and €2,480 for ISRPDs.
- Total tariff-based costs were €850 for RPDs and €2,610 for ISRPDs.
- The incremental cost-effectiveness ratio (ICER) was €80 per OHIP point and €786 per MAI point gained with ISRPDs (using opportunity costs).
Conclusions:
- Supporting RPDs with implants is cost-effective if payers value an OHIP point gain at over €80.
- An investment of €786 per MAI point gained is required for implant-supported treatment.
- The QALY-based cost-effectiveness was negligible, indicating limited impact on general health perception.
