A prospective study on the clinical performance of polysiloxane soft liners : one-year results . OBJECTIVE The aim of the present study was to evaluate the clinical performance of four denture soft liners up to 12 months . MATERIALS AND METHODS Thirty-three edentulous patients who experienced difficulties when using hard denture bases because of changes in denture-supporting tissues were accepted for the study and randomly received Molloplast B , GC Reline Soft , Silagum Comfort , or Mollosil Plus relines . Performance of the materials was evaluated using nine criteria at 3 , 6 , and 12 months : physical integrity , surface detail , adhesion , color , odor , plaque accumulation , resilience , hygiene , and mucosal condition . A four-point categorized scale ( 1=poor , 2=fair , 3=good , 4=excellent ) was used . Unscheduled maintenance events and the presence of fungal colonization were also recorded . RESULTS The percentage of patients available at 3 , 6 , and 12 months were 91 % , 91 % , and 66 % . Main reasons for dropouts and discontinuation were fractured dentures and patient dissatisfaction . At 6 months , 96 % of the performance scores were good or excellent and the largest changes were observed for physical integrity , surface detail , color , and fungal colonization . Fungal colonization was the most commonly observed problem and was the only reason of failure at 12 months . CONCLUSIONS The clinical performance of all soft liners was slightly impaired over the 12-month observation . Except for cases showing extensive fungal colonization , the observed changes in clinical performance did not necessitate remaking of the dentures . Mollosil Plus showed a performance comparable to that of Molloplast B , and the other materials had slightly lower performance especially in terms of fungal colonization .
