目的：分析即刻种植术后可能影响上颌牙槽嵴改建的因素。方法：共80例接受上颌即刻种植的患者，在上颌前牙及前磨牙区拔牙后即刻植入80枚种植体。检查并记录如下数据：①种植体表面距颊侧牙槽嵴外侧骨板的距离；②种植体颊侧水平骨缺损距离；③种植体颊侧垂直缺损距离。并于术后4个月行二期手术时复查上述数据。依据以下3个原则进行分析：颊侧牙槽骨厚度；缺牙位置；是否因牙周病拔牙。结果：当颊侧骨板较厚时，牙槽嵴吸收量较少。前磨牙区域牙槽嵴吸收量较少。结论：颊侧骨板的厚度及缺牙位置均有可能影响术后牙槽嵴的改建。在行即刻种植术时，临床医师必须密切关注种植体颊侧骨板的厚度，水平缺损的宽度等条件。

Objective: To analyze the factors which may influence the maxillary alveolar ridge alterations after immediate implantation. Methods:Data were obtained from 80 patients who received immediate dental implants (80 implants) in an-terior and premolar segments in maxilla. Following data were recorded: ① The distance between the implant surface and the outer border of the bone crest.②The distance between the implant surface and the inner border of the bone crest. ③The vertical residual gap were checked. The above variables were examined again four months later. Statistical treatment was based on the following principles: ① The thickness of the buccal bone wall. ② The position of the missing tooth. ③The cause of tooth extraction. Results: In cases which the buccal bone wall was thick, the amount of bone absorption was small. In the premolar segment, the absorption of alveolar ridge was less than the incisor-canine segment. Conclusion:The thickness of buccal bone wall and position of missing tooth, may influence the maxillary alveolar ridge alterations after im-mediate implantation. Clinicians must consider the thinkness of the buccal bony wall and the horizontal gap in the practice during immediate implants.
