Abstract

Background: 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.

Methods: 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.

Results: 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.

Conclusions: 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.

锥形自攻骨水平植入体即刻植入后的长期存活率:位置有效原理。
背景:即刻植入种植体因其多种优点而越来越受欢迎。然而,即刻种植也有其挑战,包括对种植体周围的初期稳定性和骨形成的担忧。本研究旨在评估锥形、喷砂和酸蚀内埋入式牙科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依据:2009年至2018年期间,韩国首尔国立大学牙科医院的一名外科医生为34名患者拔牙后立即植入了49颗锥形骨水平设计的种植体。收集并评估了临床结果,重点关注种植体植入位置和边缘骨缺失(MBL),同时考虑了种植体直径和长度等其他参数:49颗即刻安装的Luna®(Shinhung Co.,韩国首尔)牙科植入体中,23颗植入下颌骨,26颗植入上颌骨。安装时患者的平均年龄为 65.91 岁,从 40 岁到 86 岁不等。平均随访时间为 7.43 年,从 5 年到 14 年不等。对锥形种植体、喷砂种植体和酸蚀内埋植种植体进行为期 5 年的回顾性评估后,即刻种植体的累积存活率为 93.88%,其中下颌骨和上颌骨前磨牙区的存活率均为 100%:经过 5 年的评估,锥形、喷砂和酸蚀内埋入式种植体在牙弓内不同位置的即刻植入效果良好,表现出有效的临床表现。
