目的 在这项研究中，介绍了在无牙颌下颌中使用杆连接覆盖义齿进行 ITI 喷砂、大砂粒、酸蚀 (SLA) 种植体即刻负重的初步结果。 材料和方法 本研究纳入了 10 名年龄在 48 岁至 74 岁之间的无牙颌患者。所有患者在椎间孔区域接受 2 个 SLA 表面 ITI 实心螺钉牙种植体，种植体植入 1 天后装载有杆连接器和覆盖义齿。使用根尖周X线照片评估边缘骨吸收。评估牙龈健康（即出血指数）和患者​​满意度（使用视觉模拟量表测量）。种植体负重后随访时间为 24 至 36 个月（平均时间 29.8 个月）。 结果 植入 24 个月后，20 个种植体没有一个失败。 12 个月后，所有种植体周围的边缘骨吸收平均为 0.71 毫米，92% 的部位出血指数为 0。12 至 24 个月期间，平均骨吸收额外增加 0.08 毫米。所有患者的生活质量均得到改善。 讨论 骨吸收量与标准加载时间的研究中报告的量相当。本研究中种植体周围软组织的低炎症率和患者的高满意度表明了令人鼓舞的短期结果。 结论 结果表明，2 个牙种植体的即刻负重可以成功，并进一步支持在残余骨中使用粗糙的种植体表面。
PURPOSE In this study, preliminary results of immediate loading of ITI sandblasted, large-grit, acid-etched (SLA) implants with a bar-connected overdenture in the edentulous mandible are presented. MATERIALS AND METHODS Ten edentulous patients between 48 and 74 years old were included in this study. All patients received 2 SLA-surfaced ITI solid-screw dental implants in the interforaminal region, which were loaded with a bar connector and an overdenture 1 day after implant placement. Marginal bone resorption was evaluated using periapical radiographs. Gingival health (ie, Bleeding Index) and patient satisfaction (measured using a visual analog scale) were evaluated. Follow-up time was 24 to 36 months (mean time 29.8 months) after implant loading. RESULTS Twenty-four months after placement, none of the 20 implants had failed. Marginal bone resorption around all implants after 12 months averaged 0.71 mm, and 92% of the sites had a Bleeding Index of 0. Between 12 and 24 months, average bone resorption was an additional 0.08 mm. All patients demonstrated an improved quality of life. DISCUSSION The amount of bone resorption was comparable to amounts reported in studies with standard loading times. The low rate of inflammation of the peri-implant soft tissue and the high level of patient satisfaction in this study demonstrate encouraging short-term results. CONCLUSION The results suggest that immediate loading of 2 dental implants can be successful and further support the use of a rough implant surface in residual bone.
