TY - JOUR ID - TI - Shear Bond Strength of Acrylic Soft Liner after Incorporation of Silver- Zinc Zeolite AU - Huda Alaudeen Sadeq AU - Israa Mohammed Hummudi PY - 2019 VL - 6 IS - 2 SP - 1 EP - 12 JO - Journal of Oral and Dental Research مجلة طب الفم والاسنان SN - 23106417 AB - Background The main disadvantages the soft liners, is the absence of a durable bond to the denture base, this caused adhesion failure between them, creating an environment for colonization bacterial and compromise the durability of the Soft denture liners. The objective of this study was to evaluate the effect of silver-zinc zeolite incorporated into heat cure acrylic soft liner on shear bond strength.Materials and methods Thirty specimens of heat cure soft liner were prepared and divided into three groups after incorporation of Ag-Zn as follows; Control Group: which have 10 specimens without Ag-Zn zeolite. Experimental Group: which have ten specimens with 0.5% by weight of Ag-Zn; Experimental Group: which have 10 specimens with 0.75% weight of Ag-Zn zeolite plastic pattern sample which used for acrylic block fabrication were (75 mm length × 25 mm width × 5 mm depth. The handle of acrylic block thickness is 13mm. Shear bond strength of all specimens was evaluated.Results The LSD test showed The experimental groups of 0.75% and 0.5%significant difference compared with the control group (p<0.05). While the comparison between experimental groups (0.75 % and 0.5 %) had recorded non-significant difference at p >0.05. Conclusions incorporation from (0.5% and 0.75%) of Ag-Zn Zeolite into heat soft liner had a significant effect on shear bond strength.
