16648TITLE OF THE INVENTIONARTIFICIAL TEETH THAT MINIMIZE STRESSESON DENTURE SUPPORTING TISSUEABSTRACT OF THE DISCLOSUREArtificial posterior teeth of non-interlockingconstruction having flat surfaces parallel to the plane oflateral tooth movement that form a major portion of theocclusal surfaces. Since the teeth can freely slidelaterally on one another, side stresses that would tend toshift the dentures are avoided, even though a cross-bitesetup is used. Each tooth has a laterally extending, foodpositioning and holding groove and one or more spillwaysthereon that permit fluids and comminuted food to escape,thereby reducing hydraulic pressure.
