无代偿性缺牙对口腔功能的影响

The effects of uncompensated tooth loss on oral functions

调查了６６例缺牙后未镶复的成年患者，并从咀嚼的机理出发，讨论无代偿性缺牙造成的不良影响。认为当牙齿缺失后，除缺牙区牙槽骨会发生变化外，还可导致余留牙向缺隙倾斜，对牙向缺隙伸长，丧失正常邻接关系，产生早接触和干扰，造成食物嵌塞、继发龋和牙周病等。因此，及时修复缺牙非常重要，可减少或减轻由缺牙而引起的不良情况。

cases of tooth loss without restorations have been investigated. The article discusses the harmful effects of the uncompensated tooth loss from mechanism of mastication, and it points out that the tooth loss, apart from alteration of alveolar bone in edentulous space, may lead to the drift of the remaining tooth toward the edentulous space, and the supraeruption of the opposed tooth toward the edentulous space, losing the relationship between adjacent teeth. These alterations result in premature contact, interfere with the normal occlusion and cause food impaction, secondary caries, periodontal disease, etc.Therefore, it is very important to immediately restore teeth loss. This may reduce and lighten the harmful effects of the uncompensated tooth loss.
