Evaluating the cost-effectiveness of prosthetic rehabilitation for partially edentulous teeth in India: A comparative study of Clasp-Retained RPDs, Thermoplastic Resin RPDs, and Cast Partial Dentures

Abstract

Background

With rising life expectancy, partial edentulism has increased, particularly in developing nations where economic constraints, limited awareness, and inadequate dental care exacerbate the burden on aging populations. Patients with fewer than 20 teeth often experience a reduction in Oral Health-Related Quality of Life (OHRQoL), emphasizing the need for effective tooth replacement. Removable partial dentures (RPDs) are versatile, cost-effective solutions for partial tooth loss, including metal clasp-retained RPDs (MC-RPDs), thermoplastic resin RPDs (TR-RPDs), and cast partial dentures (CPDs).

Methods

This study evaluates the oral health-related quality of life, patient satisfaction, and cost-effectiveness of these three RPD types. A cross-sectional study was conducted with 42 participants, divided into three groups: MC-RPD, TR-RPD, and CPD, each with 14 patients. The Oral Health Impact Profile (OHIP-14) and Satisfaction Questionnaire (SAT) were administered at baseline and three months post-denture delivery. The study adhered to Consolidated Health Economic Evaluation Reporting Standards.

Results

Results showed significant differences in OHIP scores between the groups, with CPD offering the highest quality of life, followed by TR-RPD, and MC-RPD. Post-treatment, the mean OHIP scores for MC-RPD, TR-RPD, and CPD were 30.57 ± 4.09, 20.71 ± 4.03, and 22.36 ± 2.92, respectively, with CPD showing the greatest improvement. Patient satisfaction was highest for CPD, followed by TR-RPD, and least for MC-RPD. However, satisfaction differences between the groups were not statistically significant after three months.

Conclusion

This study highlights the superior performance of CPDs in enhancing OHRQoL and patient satisfaction, though their higher cost may limit accessibility. These findings provide valuable insights for dental practitioners and patients in selecting the most suitable and cost-effective RPD treatment options.
