Immediate implant placement has gained popularity due to its several advantages. However, immediate placement has its challenges, including concerns about primary stability and bone formation around the implant. The aim of the present study is to evaluate the clinical outcomes of tapered, sand-blasted, and acid-etched internal submerged dental implants in various regions of the jaw bones and to provide a positional rationale for immediate implant placement.
Between 2009 and 2018, a single surgeon at Seoul National University Dental Hospital in Seoul, Korea, immediately inserted 49 dental implants with tapered bone-level design after extraction, in a total of 34 patients. The clinical outcomes were collected and evaluated, focusing on location of implant placement and marginal bone loss (MBL), with consideration of other parameters such as implant diameter and length.
Of 49 immediately installed Luna® (Shinhung Co., Seoul, Korea) dental implants, 23 were placed in the mandible, and 26 were set in the maxilla. The mean age of patients at the time of installation was 65.91 years, ranging from 40 to 86 years. The average follow-up period was 7.43 years, with a range of 5 to 14 years. After a 5-year retrospective evaluation of tapered, sand-blasted, and acid-etched internal submerged dental implants for immediate implant placement, the cumulative survival rate was 93.88%, with 100% survival rate in the mandible and premolar region of both the maxilla and mandible.
After a 5-year evaluation, tapered, sand-blasted, and acid-etched internal submerged dental implants demonstrated good efficacy for immediate placement in various locations within the dental arches, exhibiting effective clinical performance.
即刻种植因其诸多优势而越来越受欢迎。然而，即刻种植也面临挑战，包括对种植体初期稳定性以及种植体周围骨形成的担忧。本研究的目的是评估锥形、喷砂和酸蚀内部潜入式牙种植体在颌骨不同区域的临床效果，并为即刻种植提供位置选择依据。
2009年至2018年期间，韩国首尔国立大学牙医院的一名外科医生在34例患者拔牙后即刻植入了49颗具有锥形骨水平设计的牙种植体。收集并评估临床效果，重点关注种植体植入位置和边缘骨吸收（MBL），同时考虑其他参数，如种植体直径和长度。
在即刻植入的49颗Luna®（韩国首尔新洪公司）牙种植体中，23颗植入下颌骨，26颗植入上颌骨。患者植入时的平均年龄为65.91岁，范围在40至86岁之间。平均随访期为7.43年，范围在5至14年之间。对锥形、喷砂和酸蚀内部潜入式牙种植体进行5年回顾性评估以用于即刻种植后，累积生存率为93.88%，下颌骨以及上颌骨和下颌骨的前磨牙区域生存率为100%。
经过5年评估，锥形、喷砂和酸蚀内部潜入式牙种植体在牙弓内不同位置即刻植入显示出良好疗效，展现出有效的临床性能。
