Immediate implant placement after tooth extraction is a predictable solution in various clinical situations. The purpose of this study was to evaluate the predictability of a treatment, including the placement of implants, using a modified insertion technique at the time of maxillary molar extraction.
Sixty-eight patients with a total of 68 teeth scheduled for tooth extraction and immediate implant placement into fresh sockets were included in the study. Implants were positioned just after teeth removal and, in case of necessity, a regenerative therapy was performed at the same time. After a 3-month period of healing, implants were restored with single crown fixed prostheses.
All implants restored with single crowns were monitored for 36 months; only, 3 implants failed with a cumulative survival rate of 97.96%.
The combination of atraumatic extraction of maxillary molars, sufficient residual inter-radicular bone, and the use of appropriate regenerative material at the time of implant insertion, represents a predictable long-term treatment.
拔牙后即刻种植是各种临床情况下一种可预测的解决方案。本研究的目的是评估一种治疗方法的可预测性，包括在拔除上颌磨牙时使用改良的植入技术来植入种植体。
本研究共纳入 68 名患者，共 68 颗牙，计划拔牙并即刻将种植体植入新鲜牙槽窝。在拔牙后立即放置种植体，如果需要，同时进行再生治疗。经过 3 个月的愈合期，用单冠固定修复体修复种植体。
所有用单冠修复的种植体均被监测了 36 个月；只有 3 个种植体失败，累计存活率为 97.96%。
在上颌磨牙微创拔除、足够的根间剩余骨量以及在植入种植体时使用适当的再生材料的情况下，代表了一种可预测的长期治疗方法。
