Wear, extraction, or fracture of all or part of a mandibular first molar can lead to the supraeruption of the opposing maxillary molar, resulting in occlusal interference and lack of restoration space. This report describes a method to gain sufficient vertical space for permanent restoration. A direct composite resin restoration was placed on the occlusal surface of a lower molar, intentionally making the interim restoration high and intruding the maxillary molar. After 6 weeks, the extruded tooth returned to the desired position, and functional occlusion was restored, enabling a ceramic restoration on the mandibular molar. No marked adverse sensory reaction was reported in this therapeutic process, and no deleterious signs were detected in the teeth, periodontium, or temporomandibular joints. The simple treatment type was effective, noninvasive, and time saving, while also preserving maximum tooth structures.
下颌第一磨牙全部或部分磨损、拔除或折断可导致对颌上颌磨牙的伸长,从而导致咬合干扰和修复空间不足。本报告描述了一种获得足够垂直空间进行永久修复的方法。在下颌磨牙的咬合面上放置直接复合树脂修复体,有意使临时修复体较高,从而使上颌磨牙伸长。6周后,伸长的牙齿回到理想位置,恢复了功能性咬合,使得下颌磨牙能够进行陶瓷修复。在这个治疗过程中未报告明显的不良感觉反应,在牙齿、牙周组织或颞下颌关节中也未检测到有害迹象。这种简单的治疗方式有效、无创且节省时间,同时还能最大程度地保留牙齿结构。
