The tilted molar presents both prosthetic and periodontal problems. Typically, the loss of a lower first molar or second premolar produces a space and allows the molar, distal to the space, to tilt mesially. The major tilting force is produced by the opposing occlusion. Although a tightly locked occlusion can prevent excessive movement, once the tooth begins to tilt, the vector of force tends to increase the tilting. The severity of both prosthetic and periodontal problems is directly related to the amount of tilting and treatment becomes complex when adjacent teeth begin to migrate.
倾斜磨牙会带来修复和牙周两方面的问题。通常，下颌第一磨牙或第二前磨牙缺失会形成一个间隙，使得该间隙远中的磨牙向近中倾斜。主要的倾斜力由对颌咬合产生。尽管紧密锁结的咬合可防止过度移动，但一旦牙齿开始倾斜，力的矢量往往会加剧倾斜。修复和牙周问题的严重程度都与倾斜程度直接相关，当相邻牙齿开始移位时，治疗就会变得复杂。
