Immediate implant placement (IIP) in fresh extraction sockets exhibits similar survival and success rates to delayed implant placement in healed sockets. Several advantages of IIP involve shortened total treatment time, reduction of the number of invasive surgeries, and subsequent reduction of patient discomfort due to lack of additional surgeries. The major shortcomings in IIP, however, include the inability to obtain early bony support, presence of a gap between the extraction socket and fixture, and the inability to cover the fixture with soft tissue, leading to increased risk of infection and implant loss. When IIP is performed, atraumatic or minimally traumatic extractions, conservation of the septal bone in molars, minimal flap elevation or flap-less surgery, bone grafting the gap between the fixture and the extraction socket, and coverage with soft tissue or a membrane must be considered.
在新鲜拔牙窝中即刻种植(IIP)与在愈合牙槽窝中延迟种植的生存率和成功率相似。IIP的几个优点包括缩短总治疗时间、减少侵入性手术的次数以及由于无需额外手术而减少患者不适。然而,IIP的主要缺点包括无法获得早期骨支持、拔牙窝与种植体之间存在间隙以及无法用软组织覆盖种植体,从而导致感染和种植体丢失的风险增加。进行IIP时,必须考虑采用无创或微创拔牙、保留磨牙的牙槽间隔骨、尽量减少瓣的掀起或不翻瓣手术、在种植体与拔牙窝之间的间隙进行骨移植以及用软组织或膜覆盖。
