This retrospective report describes an individual prosthodontist's views regarding clinical factors that presumably influence the frequency of relining procedures (FRP) during the maintenance period of removable prostheses. Patient selection was composed of 60 removable prosthesis-wearing individuals who had been clinically monitored and maintained at 3-month intervals for periods ranging from 5 to 25 years. The FRP was designated as the dependent value, and the number of occlusal supporting areas, number of remaining teeth, sex, and age were designated as independent values using linear regression analysis (P .05). Factors influencing the FRP were the number of occlusal supporting areas and patient age; the period between relining procedures increased as occlusal supporting areas and age increased.
