Results: Teeth opposing Feldspathic material showed the statistically significantly highest mean amount of wear and teeth opposing lithium disilicate showed significantly lower mean amount of wear. While, teeth opposing zirconia showed the statistically significantly lowest mean amount of wear UR - http://172.23.153.220/th.pdf ER -
