There is limited information regarding marginal bone-level changes around immediately loaded implants placed with the osteotome technique. The aim of this case series is to prospectively evaluate the clinical and radiographic outcome of immediately loaded implants placed with the osteotome technique over a 12-month period.
Eighteen patients in need of oral prosthetic rehabilitation that included single implant placement in positions #4 to #13 and/or #20 to #29 participated in this prospective trial. A modified implant installation procedure with an under preparation of the implant bed using the osteotome technique and immediate loading of the implant was performed. Clinical examinations were performed at 2 weeks, 6 months, and 12 months of follow-up. Radiographic examinations were performed at implant installation and at the 6- and 12-month follow-up visits.
One implant failed to integrate and was removed at 3 months after implant installation. Four of 20 implants had insertion torque value >35 Ncm. The mean marginal bone loss was -0.09 mm at the 6-month and -0.19 mm at the 12-month follow-up visits.
The present case series indicates that implants placed with the osteotome technique and immediately loaded did not demonstrate a high insertion torque and exhibited minimal marginal bone loss.
关于使用骨凿技术植入的即刻负重种植体周围边缘骨水平变化的信息有限。本病例系列研究的目的是前瞻性评估在 12 个月的时间内使用骨凿技术植入即刻负重种植体的临床和影像学结果。
本前瞻性试验纳入了 18 名需要口腔修复的患者,这些患者需要在 #4 到 #13 号和/或 #20 到 #29 号位置植入单个种植体。采用改良的种植体安装程序,使用骨凿技术对种植体床进行预备,并即刻加载种植体。临床检查在植入后 2 周、6 个月和 12 个月进行。在植入时和 6 个月和 12 个月的随访时进行影像学检查。
有 1 颗种植体在植入后 3 个月未能整合,被取出。20 颗种植体中有 4 颗的植入扭矩值>35 Ncm。6 个月和 12 个月随访时,平均边缘骨损失分别为-0.09 毫米和-0.19 毫米。
本病例系列研究表明,使用骨凿技术植入并即刻负重的种植体并未显示出较高的植入扭矩,且边缘骨丧失最小。
