Low-cost implant overdenture option for patients treated in a predoctoral dental school curriculum.

In an effort to make the implant overdenture more affordable for patients, a pricing package at the University of Alabama at Birmingham School of Dentistry was established. This package includes two implants, two dentures (upper and lower), and two implant abutments, all for $975. It is known as the "2-2-2" implant program. One concern regarding the program was whether patients would complete overdenture treatment or simply receive implants at this relatively low cost and have the implants restored outside the school. The purpose of this retrospective chart review was to determine how many patients in 2004 received implants as part of this program and how many of these patients completed overdenture treatment. Other data (age, distance from school, number of teeth at start of treatment, and gender) were collected to identify variables that might be associated with greater likelihood of completing overdenture treatment. In 2004, fifty-one patients received 102 implants as part of this program. Two patients had a failed implant prior to restoration (two of 102 implants), and one patient was referred to graduate prosthodontics for restoration. Of the remaining forty-eight patients, forty-one completed overdenture treatment (85 percent), and seven (15 percent) were lost to follow-up. The mean age of patients receiving this treatment was 60.7 years. The mean distance traveled to the school was 70.7 miles. While no variables showed significant predictive value, point estimates (estimate of the odds ratio) suggest that older patients and patients who travel greater distance to the school were less likely to complete treatment. The low-cost implant overdenture has been an important addition to our curriculum. The majority of patients who receive implants as part of this program complete overdenture treatment.
