Abstract：
BACKGROUND: The posterior maxilla presents challenges for implant insertion because of the poor bone quality as well as the loss of vertical bone height. Indirect transcrestal sinus lift techniques are advised when a few millimeters of additional height are needed. This study aimed to evaluate the clinical and radiographic outcomes of antral membrane balloon technique versus Densah burs for transcrestal maxillary sinus lifting with simultaneous implant placement.
METHODS: This randomized clinical trial was conducted on 22 patients received 32 dental implants for replacement of missed maxillary posterior teeth after crestal maxillary sinus lifting. The patients were randomly divided into two groups. Group 1, patients underwent crestal sinus floor elevation with simultaneous implant placement using antral membrane balloon technique. Group 2, patients underwent crestal sinus floor elevation with simultaneous implant placement using Densah burs. Patients were evaluated clinically and radiographically using cone beam computed tomography (CBCT) at regular time intervals immediately, 6 months and 12 months after surgery. All clinical and radiographic parameters were statistically analyzed.
RESULTS: All dental implants were successful for 12 months of follow up. Regarding implant primary stability, there was a statistical significant difference between the study groups in favor of Densah group (P = 0.004), while there was no significant difference after 6 months (P = 0.07). Radiographically, balloon group showed a statistically significant immediate postoperative vertical bone height (P < 0.0001), and significant reduction in vertical bone height after 6 months (P < 0.0001). Densah group showed significant increase in bone density (P ≤ 0.05).
CONCLUSIONS: Both techniques demonstrated successful clinical and radiographic outcomes for crestal sinus lift. The antral membrane balloon group demonstrated better immediate postoperative vertical bone gain, while Densah burs had higher implant primary stability and bone density.

摘要：
背景：由于骨骼质量差以及垂直骨高度的损失，上颌骨后部对植入物插入提出了挑战。当需要增加几毫米的高度时，建议采用间接的经齿窦提升技术。这项研究旨在评估窦膜球囊技术与Densahburs在同时放置植入物的情况下进行经颌骨上颌窦提升的临床和影像学结果。
方法：这项随机临床试验是对22例患者进行的，这些患者接受了32次牙种植体，用于在上颌窦抬升后替换错过的上颌后牙。将患者随机分为两组。第1组，患者使用窦膜球囊技术同时进行植入植入，同时进行窦底抬高。第2组，患者使用Densahburs同时进行植入物植入，同时进行了窦底抬高。立即定期使用锥形束计算机断层扫描（CBCT）对患者进行临床和影像学评估，术后6个月和12个月。对所有临床和影像学参数进行统计分析。
结果：所有牙种植体均成功，随访12个月。关于植入物的主要稳定性，有统计学上的显著差异，有利于Densah组（P=0.004），6个月后差异无统计学意义(P=0.07)。射线照相,球囊组术后即刻垂直骨高度有统计学意义(P<0.0001),6个月后垂直骨高度显著降低(P<0.0001)。Densah组骨密度显著增加(P≤0.05)。
结论：两种技术均显示出成功的临床和影像学结果。窦膜球囊组表现出更好的术后即刻垂直骨增益，而DensahBurs具有较高的种植体初级稳定性和骨密度。
