Cost-effectiveness of Mandibular Two-implant Overdentures and Conventional Dentures in the Edentulous Elderly

Abstract

Implementation of new therapies is usually governed by financial considerations, so efficacy studies should also include cost comparisons. The cost and effectiveness of mandibular conventional dentures (CD, n = 30) and two-implant overdentures (IOD, n = 30) were compared in elderly subjects. Effectiveness (Oral Health Impact Profile, OHIP-20) and cost were measured up to one year post-treatment. Data for subsequent years were estimated by the Delphi method. Using an average life expectancy of 17.9 years, the equalized annual costs (in Canadian dollars) were dollar 399 for CD and dollar 625 for IOD (p < 0.001), and the equalized annual values for the outcome (OHIP-20) were 47.0 for CD and 31.3 for IOD treatment (p < 0.05). These values translate into a yearly additional cost for IOD treatment of dollar 14.41 per OHIP-20 point. These results are key to the implementation of programs to provide this form of therapy for edentulous adults.

Oral health self-perception evaluation using mandibular overdenture prosthesis in public health care

“…Heydecke et al 22 reported that overdenture with two implants adds up to 56% more to the final cost when compared to conventional dentures, however , the quality of life improves by 33%. The overdenture model reported in this paper has relative technical simplicity and low cost, and it was possible to transform lower dentures into overdenture stabilized by 3 implants in one session of about an hour, improving the quality of life associated with oral health.…”

Treatment satisfaction and oral health behavior of the before and after dental implanting treatment

“…The previous study revealed the satisfaction of the dental implant treatment and showed a positive recommendation of treatment [20][21][22][23] . A positive response to each question was similar to those of Pjetursson et al 22) and Jeong et al 23) .…”

Food choices of edentulous adults with implant-supported overdentures and conventional dentures

“…[4][5][6] With food selection and ability to consume hard or tough food being one aspect of patient satisfaction, this study showed that there was no difference in that aspect whether patients were using conventional complete dentures or implant-retained ones. This was explained through patient predisposition to using either type of dentures; ie, patients who are ready or willing to use conventional dentures will generally have improvement in their food selection and ability to consume hard food.…”
