Abstract (2. Language): 
Soft denture liners reduce the height of peak stress as a function of masticatory force and distribute stresses more evenly to the supporting structures that would diminish the pain. The purpose of this study was to determine how a soft denture liner affects the masticatory performance and efficiency of complete dentures. The sample comprised 10 women (ages 52-69) with mandibular hard-based complete dentures (control) which were subsequently lined with Molloplast-B resilient liner for comparison. Masticatory performance and efficiency were measured by dividing the volume of chewed peanuts passing through standard sieves by the total test food (3 g). Masticatory performance data (mean±Sd in ratios) for hard base were: 53.13 ± 11.49, for soft-base were: 61.42 ± 6.01. Masticatory efficiency data (mean±Sd in ratios) for hard-base dentures were: 65.97 ± 11.25, for soft-base were: 73.21 ± 5.00. The data were analyzed by Wilcoxon rank test (p<0.05). Masticatory performance and efficiency were significantly different between Molloplast-B-lined dentures compared to control. It was concluded from this study that soft denture liners can improve the masticatory performance and efficiency of denture wearers.

Abstract (Original Language): 
Protezler altında kullanılan yumuşak astar maddeleri çiğneme sırasındaki maksimum kuvvetlerin iletimini azaltarak ve basınçların eşit dağılımını sağlayarak destek dokularda meydana gelebilecek ağrı duyusunu hafifletirler. Bu çalışmada yumuşak astar maddesi Molloplast-B'nin tam protezlerin çiğneme performansı (ÇP) ve çiğneme etkinliği (ÇE)'nde meydana getirdiği değişimler incelenmiştir, 10 kadın hastaya (yaş 52-69) uygulanan akrilik sert kaideli tam protezler İle (kontrol grubu), daha soma Mollop-last-B ile astarlanan aynı protezler (deney grubu) karşılaş-tırılmıştır. ÇP ve ÇE değerleri, standart eleklerden geçen çiğnenmiş yerfıstığı (test yiyeceği) miktarının toplam test yiyeceği miktarına (3 gr) bölünmesiyle elde edilmiştir. ÇP değerleri (% olarak X±Sd) sert kaideli protezler için 53.13 ± 11.49, yumuşak astarlı protezler için ise 61.42 ± 6.01 bulunmuştur. ÇE değerleri ise (% olarak ±Sd) akrilik sert kaideli protezler için 65.97 ± 11.25, yumuşak astarlı protezler için ise 73.21 ± 5.00 olarak saptanmıştır. Verilerin istatistiksel değerlendirmesi Wilcoxon testi ile yapılmış (p<0.05) ve Molloplast-B ile astarlanmış protezlerin ÇP ve ÇE değerleri ile sert kaideli akrilik protezlerin aynı değerleri arasındaki farklar anlamlı bulunmuştur. Sonuç olarak yumuşak astar maddelerinin protez kullanan hastalarda çiğneme performansı ve etkinliğini artırdığı saptanmıştır.
