The technique described provides the dentist with a means of diagnostically restoring the vertical dimension of occlusion for an edentulous patient, without permanently altering the dentures. This procedure is accomplished with a removable mandibular splint, which snaps over the mandibular denture. The procedure involves little clinical treatment time. The maxillary denture may also be temporarily overlayed in a similar manner, but the procedure is generally not as esthetically acceptable. Since the mandibular alveolar bone resorbs much faster than that of the maxillae in most edentulous patients, the mandibular denture usually is responsible for most of the loss of occlusal vertical dimension. The mandibular denture is therefore most frequently indicated for alteration to restore lost occlusal vertical dimension. Medicolegal implications, as well as practical considerations, suggest that the patient's present dentures should not be permanently altered before new dentures are found to be satisfactory.
所描述的技术为牙医提供了一种诊断性恢复无牙患者咬合垂直距离的方法，而无需永久性改变义齿。该过程通过一个可摘戴的下颌夹板来完成，该夹板扣在下颌义齿上。该过程所需临床治疗时间很少。上颌义齿也可以以类似的方式进行临时覆盖，但该过程在美学上通常不太容易被接受。由于在大多数无牙患者中，下颌牙槽骨的吸收比上颌牙槽骨快得多，下颌义齿通常是导致咬合垂直距离丧失的主要原因。因此，下颌义齿最常被用于改变以恢复丧失的咬合垂直距离。法律方面的影响以及实际考虑因素表明，在发现新义齿令人满意之前，不应永久性改变患者现有的义齿。
