THE EFFECTS OF REMOVABLE OVERDENTURE PROSTHESES OF WHICH RETENTION WERE ACHIEVED BY MOLLOPLAST-B ON CHEWING PERFORMANCE (A two-year longitudinal study) Anahtar kelimeler Cigneme performansi, Molloplast-B, Parsiyel Anodonti, disustti protez. Tutuculugu Molloplast-B ile saglanmis hareketli disustu protezlerin, cigneme performansina etkileri 5 vaka uzerinde arastirilarak, 2 yillik gozlemlerin sonuclan aciklanmistir. Parsiyel anodonti vakalarina uygulanan bu tur protezler protez oncesi ve protez sonrasi belirli periodlarla (1 ay, 3 ay, 1 yil, 2 yil) cigneme performans testleri ile incelenmistir. Sonuc olarak, tutuculugu molloplast-B ile saglanmis muteharrik disustu protezlerde cigneme performansi degerleri protez oncesi degerlere oranla anlamli derecede artmis ve bu degerler, 2 yil icinde gittikce yukselmistir. Key words; Chewing performance, Molloplast-B, Partial anodontia, overdenture prostheses. In five patients, the effects of removable overdenture prostheses of which retention were achieved by Molloplast-B on chewing performance were investigated and 2 year longitudinal results were explained. These prostheses which were applied for Partial Anodontia cases were investigated with chewing performance tests before and after wearing overdenture prostheses during periodic controls (1st month, 3rd month, 1st year, 2nd year). As a result, in overdenture prostheses of which retention were achieved by Molloplast-B, chewing performance values increased significantly with respect to values before application of the prostheses and these values has increased in 2 years period.
