In deciding whether to replace lost lower molar teeth with a denture or accept the status quo, the dentist is faced with a choice of equally unfavourable alternatives. Dentures tend to accumulate plaque, the main cause of periodontal destruction, but failure to provide a prosthesis may also disadvantage the patient. Whether or not the provision of a replacement partial denture following molar tooth extraction helps to maintain the periodontium of the remaining dentition is not known. Patients are also aware of the dilemma. Many surveys have shown that a large proportion of replacement lower, free-end saddle dentures are never worn. However, a failure to provide partial dentures may have many adverse effects, especially in young adults.
在决定是用假牙替换缺失的下颌磨牙还是维持现状时，牙医面临着同样不利的选择。假牙容易积聚牙菌斑，这是牙周破坏的主要原因，但不提供假牙也可能对患者不利。拔除磨牙后提供局部义齿是否有助于维持剩余牙列的牙周组织尚不清楚。患者也意识到了这种困境。许多调查表明，很大一部分下颌游离端鞍形假牙从未被佩戴过。然而，不提供局部义齿可能会产生许多不良影响，尤其是在年轻人中。
