49 treated adult patients with deep-bite were classified by analysing orthodontic models and lateral cephalograms differentiating skeletal, dento-alveolar deep-bite and class I, class II-1, class II-2 malocclusion. Change of overbite and position of incisors were described within every group and compared with the other groups.
On the average overbite decreased about 3.5 mm, mostly however combined with root resorptions in the maxillary front. After removing the appliance overbite relapsed about 1.7 mm at 93.3% of cases. The percentage of factors which made possible a decrease of overbite was described and parameters which caused the relapse were discussed. Interpreting the results of orthodontic treatment in adults, it seems to be legitimized in some exactly indicated cases but, treatment in adults is not the best time for correcting deep-bite.
通过分析正畸模型和头颅侧位片，对49例接受治疗的成年深覆牙合患者进行分类，区分骨骼性、牙-牙槽性深覆牙合以及安氏Ⅰ类、Ⅱ类1分类、Ⅱ类2分类错牙合。描述了每组内覆牙合的变化和切牙位置，并与其他组进行比较。
平均覆牙合降低约3.5毫米，但大多数情况下伴有上颌前部牙根吸收。去除矫治器后，93.3%的病例覆牙合复发约1.7毫米。描述了使覆牙合降低成为可能的因素百分比，并讨论了导致复发的参数。解读成人正畸治疗结果时，在某些确切指征的病例中似乎是合理的，但是，成人时期并非矫治深覆牙合的最佳时机。
