The purpose of this prospective study was to evaluate the clinical outcome of implants immediately placed into fresh extraction sockets for the replacement of endodontically treated teeth with signs of vertical root fracture.
Sixteen partially edentulous patients, with 1 tooth scheduled for extraction and showing clinical signs and symptoms and/or radiological evidence of vertical root fracture, were included in the study. Sixteen transmucosal implants were installed immediately after extraction and careful debridement. The gap between the implant surface and the socket walls was filled using synthetic bone grafting cement. Prosthetic phase occurred 3 to 4 months after surgery. Implant success and survival and radiographic bone loss were evaluated after 1 year of function. Patient satisfaction for mastication function, phonetics, and aesthetics was also assessed by means of a questionnaire.
No implant failure occurred. The overall implant success and survival was 100% at 1 year. The mean follow-up was 13.5 months. All prostheses were successful. Periimplant bone loss after 1 year averaged 0.48 ± 0.20 mm. All patients reported full satisfaction for mastication function, phonetics, and aesthetics.
The use of a synthetic bone grafting cement in combination with immediate implant placement procedure can be considered a safe, effective, and predictable treatment option for the rehabilitation of fresh postextraction sockets.
本前瞻性研究旨在评估即刻植入新鲜拔牙窝中以替代有垂直根折迹象的根管治疗牙的种植体的临床效果。
本研究纳入了 16 名部分缺牙患者，其中 1 颗牙计划拔除，并出现垂直根折的临床症状和/或影像学证据。在拔牙和仔细清创后，立即植入 16 颗黏膜下种植体。用合成骨移植水泥填充种植体表面与牙槽窝壁之间的间隙。术后 3 至 4 个月进行修复阶段。在功能 1 年后评估种植体成功率、存活率和影像学骨吸收情况。通过问卷调查评估患者对咀嚼功能、语音和美学的满意度。
无种植体失败。种植体的总体成功率和 1 年存活率为 100%。平均随访时间为 13.5 个月。所有修复体均成功。1 年后，种植体周围骨吸收平均为 0.48 ± 0.20 毫米。所有患者均报告对咀嚼功能、语音和美学完全满意。
将合成骨移植水泥与即刻种植体植入术相结合，可作为一种安全、有效、可预测的治疗方案，用于修复新鲜拔牙窝。
