Fifteen patients who had mandibular molars uprighted unilaterally and seven patients who had mandibular molars uprighted bilaterally were examined an average of 3 1/2 years after treatment had been completed. The investigation focused on differences in clinical observations between the treated teeth and the controls on the contralateral side at the time of the recall examination. Pretreatment radiographs provided longitudinal observations. After elimination of significant but unrelated factors, including surgical pocket elimination and the presence or absence of subgingival margins, the following appeared. Changes in alveolar bone height mesial to the uprighted molars were not different from changes mesial to control teeth. Gingival inflammation scores around uprighted molars were not different from those around control teeth. Pockets mesial to uprighted molars were shallower than those mesial to control teeth. Observations on pocket depth distal to the teeth considered were inconclusive.
15例单侧直立下颌磨牙的患者和7例双侧直立下颌磨牙的患者在治疗完成后平均3年半接受了检查。该调查聚焦于复诊检查时治疗牙与对侧对照牙之间的临床观察差异。治疗前的X线片提供了纵向观察结果。在排除包括手术消除牙周袋以及龈下边缘的存在与否等显著但不相关的因素后，出现了以下情况。直立磨牙近中牙槽骨高度的变化与对照牙近中的变化无差异。直立磨牙周围的牙龈炎症评分与对照牙周围的评分无差异。直立磨牙近中的牙周袋比对照牙近中的牙周袋浅。关于所考虑牙齿远中牙周袋深度的观察结果尚无定论。
