Evaluation of the Empower model of care for partial denture clients in a public oral health care setting.

Objective: To evaluate the effectiveness of the Empower model of care (EMC) on reducing the addition of teeth to removable partial dentures (RPD).

Methods: Data reports were generated through the Titanium electronic database to retrieve all clients at Monash Dental Services (MHDS) who participated in the EMC or received an RPD prior to the implementation of EMC was assessed over a two-year period to determine if they had additional teeth added to their partial dentures (PD). A logistic regression was performed testing whether a combination of socio-demographic and clinical variables, provided a multivariate explanation of the EMC outcome.

Results: Prior to EMC, 2034 patients attended MHDS requiring RPDs with 363 returning to have teeth added. From 2018 to 2020, 38 of 584 participants in EMC returned to have teeth added to their PDs. Those in the 'High' risk group were two times more likely to return requiring additional teeth (OR = 1.99; 95%CI:1.31-3.02); each additional year of age increased the odds of requiring additional teeth (OR = 1.03; 95%CI:1.02-1.04). Participants of the EMC were more than two times less likely to require additional teeth (OR = 0.42; 95%CI:0.29-0.59). The variance in requiring additional teeth accounted for using the full model was 9.1% (η  = 0.091).

Conclusions: This analysis confirms the effectiveness of the EMC. This approach assists denture wearers to maintain good oral health and provides an effective way of managing public health funds by reducing denture repairs and additions. © 2023 Australian Dental Association.
