摘要
目的:评估种植体辅助下颌全口覆盖义齿取戴过程中使用的阻断间隔器对残留牙槽嵴骨高度变化的影响:本研究是一项随机临床试验,对 18 名患者进行了研究。所有患者均接受了三颗下颌种植体,并使用两种不同的技术直接取下种植体。患者被无偏差地随机分为两个相同的组别(第一组无阻断垫片)和(第二组无阻断垫片)。在一年的时间里,采用新参考点技术的数字射线技术来评估残留牙槽嵴骨高度的变化。对数据进行统计分析,以检验组间差异的显著性:结果:在牙槽嵴残余吸收率方面,I 组的 RRR 明显高于 II 组:结论:在牙槽嵴残余保留方面,不使用阻断间隔器比使用阻断间隔器更有利:临床意义:在可接受的生理值范围内,在取牙过程中使用阻断垫片会影响牙槽骨高度。临床意义:在可接受的生理值范围内,取牙过程中使用阻断垫片会影响牙槽骨高度,而去除阻断垫片则更有利于保留残余牙槽嵴。本文引用方式Mohammed REL, Askar OM, El-Waseef FAE, et al:牙槽骨高度变化的临床研究(随机临床试验)》。J Contemp Dent Pract 2023;24(11):847-852.
Radiographic Assessment of Three-implant-retained Mandibular Overdentures: A Clinical Study of Alveolar Bone Height Changes (Randomized Clinical Trial).
Aim: To evaluate the residual alveolar ridge bone height changes regarding the impact of the block-out spacer used during the pick-up procedures of implant-assisted mandibular complete overdentures.
Materials and methods: This study was a randomized clinical trial conducted on 18 patients. All patients received three mandibular dental implants with definitive locator attachments which were directly picked up with two different techniques. Patients were classified randomly without any bias into two equal groups (Group I block-out spacer) and (Group II without block-out spacer). Over a year, the digital radiographic technique with new technique of reference points was employed to evaluate the changes in the residual alveolar ridge bone heights. The data were statistically analyzed to test the significance difference between groups.
Results: Concerning the residual alveolar ridge resorption RRR, group I exhibited a significantly higher RRR than group II.
Conclusion: In terms of residual alveolar ridge preservation, not using the block-out spacer was more beneficial than using it.
Clinical significance: Alveolar bone heights can be affected by the use of block-out spacer during pick-up procedure within accepted physiologic values. The removal of the block-out spacer could be more beneficial with respect to the preservation of the residual alveolar ridge. How to cite this article: Mohammed REL, Askar OM, El-Waseef FAE, et al.
