Immediate implant placement into extraction sockets has been widely reported in the dental literature, but few studies have evaluated the immediate loading of such implants. In this retrospective study, we evaluated 235 implants placed into fresh extraction sites utilizing a flapless technique, followed by immediate provisionalization with non-functional single-tooth restorations, and definitive restoration within 2 weeks. Cumulative survival and success rates were 98.8% (mean follow-up = 23.1 months). Periodontitis did not adversely influence the outcome. Within the limitations of this study, immediate implant placement and restoration followed by definitive loading within 2 weeks achieved outcomes comparable to those historically reported for delayed implants.
即刻种植于拔牙窝已在牙科文献中有广泛报道,但很少有研究评估此类种植体的即刻负重情况。在这项回顾性研究中,我们评估了235颗采用不翻瓣技术植入新鲜拔牙位点的种植体,随后用无功能单颗牙修复体进行即刻临时修复,并在2周内完成最终修复。累积生存率和成功率为98.8%(平均随访时间=23.1个月)。牙周炎未对结果产生不利影响。在本研究的局限性范围内,即刻种植并修复,随后在2周内完成最终负重,所取得的结果与历史上报道的延期种植体相当。
