The Effects of Using Mandibular Free End Frame Denture First and Second Class Lever toward on Level IL-1? of Abutment Teeth

The purpose of this research is to analyze the effects of using mandibular free end frame denture first and second lever towards on levels IL- of abutment teeth. Materials and Steps 38 cases of missing mandibular free end teeth, either unilateral or bilateral, were made a free end frame denture design retainer first and second lever on each groups (19 cases). Before insertion and after 12 weeks of using mandibular free end frame denture, they were taken gingival crevicular fluid to measure the levels of IL-1 d by using ELISA (Enzyme Linked Immunosorbent Assay) method. This research is an experimental design research, using single blind which is given actions by using mandibular free end frame denture first and second class lever. Statistical analysis begins with doing characteristic test of both groups. Both groups numerical data are done to compare each groups first and second class lever with non-paired test (data distributes normally) and Mann Whitney (data doesnt distribute normally). According to non-paired test, there were obtained p value 0.000 (p value
