Denture replacement during a 14-year period in Alberta's universal dental plan for the elderly

Since 1973 Alberta's dental plan for the elderly has made government-sponsored, premium-free, comprehensive dental care available from both dentists and denturists in private practice to all residents older than 64 years. This article is based on an analysis that covered 260,000 patients from 1978 to 1992. It presents the frequency, nature, and cost of denture replacements to patients and pays particular attention to replacements administered within the allowable 5-year time limit stated by the plan for complete and removable partial dentures. During the 14-year period, about 55,000 dentures were replaced; 47% of these were replaced in the year after the individual's 5-year time limit had expired. Within the 5-year limit 1974 dentures were replaced at a nominal cost of +1.09 million, with nearly one half of these costs being attributed to denturists. Relative to the total number of dentures provided during the 14-year period, the denture replacement rate for dentists was 7% to 8%, and for denturists it was nearly three times greater at 21% to 22%. The replacement process included many crossovers by patients between dentists and denturists; for example, nearly one quarter of the 190 complete dentures initially provided by dentists were replaced by denturists within 5 years.
