The retreatment need was assessed in 148 patients wearing 125 overdent
ures in the mandible and 56 in the maxilla. The total number of abutme
nt teeth was 512. During the evaluation period 44 abutments were extra
cted. The endpoints of the survival analysis after 6 yr were 89%, taki
ng the loss of all abutments as the failure criterion for overdentures
. During the clinical examination it was found that 31% of the abutmen
ts needed retreatment while the retrospective part showed a mean yearl
y restoration need of 17.5%. Caries was the most important reason for
retreatment. These data demonstrated that patients with overdentures s
hould be regarded as high risk patients for retreatment of abutments.
Therefore a stringent maintenance program, including regular recall ap
pointments and the application of a preventive regimen, is desirable.
