Endosseous implants can be placed following either two-stage technique requiring second-stage surgery or one-stage technique, which does not involve a second surgical intervention.
The present study was undertaken to evaluate and compare the changes in crestal bone level when two-piece implants were placed in posterior mandibular region following one-stage and two-stage surgical protocol.
A parallel group randomized prospective study was designed in which 20 two-piece implants were placed in the posterior mandibular region of 16 partially edentulous healthy patients following either one-stage (Group I) or a two-stage surgical protocol (Group II). Alterations in crestal bone level were assessed with the help of DentaScan at baseline, that is, at the time of implant placement, third month and sixth month.
Nonsignificant differences were seen in both groups in terms of changes in crestal bone level at the final evaluation.
Hence, it could be concluded that two-piece implants can be placed following one-stage surgical protocol as predictably as when two-stage surgical technique is followed.
骨内种植体可以采用需要二期手术的两阶段技术或不涉及二次手术干预的一阶段技术进行植入。
本研究旨在评估和比较在一期和两期手术方案下，将两件式种植体植入下颌后牙区时牙槽嵴骨水平的变化。
设计了一项平行组随机前瞻性研究，将20枚两件式种植体分别按照一期手术方案（第一组）或两期手术方案（第二组）植入16例部分牙列缺失的健康患者的下颌后牙区。在基线时，即种植体植入时、第三个月和第六个月，借助牙科扫描评估牙槽嵴骨水平的变化。
在最终评估时，两组牙槽嵴骨水平变化方面均未观察到显著差异。
因此，可以得出结论，两件式种植体采用一期手术方案植入与采用两期手术技术植入一样具有可预测性。
