To evaluate the clinical and radiographic outcomes of placing dental implants in the posterior maxilla using the transalveolar technique.
Between January 2005 and December 2009, a total of 94 cases, 55 males and 39 females, aged (46.9 ± 11.8) years, were consecutively enrolled in this study with maxillary sinus floor augmentation using the transalveolar technique. Radiographic evaluations were conducted on panoramic and periapical radiographs at each recall. The follow-up clinical examination included cumulative survival rate(CSR) of implants, peri-implant marginal bone loss (MBL) and the height of sinus floor augmentation and the endo-sinus bone gain (ESBG).
Sinus membrane perforation was found in 4 cases.Finally 126 implants (90 cases) were placed. The perforation rate of this surgical procedure was 3.08% (4/130).Four implants lost during the healing time, the early success of implants was 96.80% (121/125). During a mean follow-up time of (34.4 ± 20.4) months, all the implants were successfully in function, with the cumulative survival rate after function loading of 100.00%. The mean MBL was (0.75 ± 0.51) mm during the healing time, and (0.48 ± 0.41) mm during the follow-up period. The mean residual bone height (RBH) was (7.27 ± 1.30) mm at the position of implants placement, the length of implant protruding into the sinus was (2.77 ± 1.15) mm, and the height of sinus floor augmentation was (4.52 ± 1.39) mm. At the loading time, the mean endo-sinus bone gain was (3.81 ± 1.60) mm. After the follow-up time of 34 months, the newly formed bone on the maxillary sinus floor underwent further remodeling with a median bone reduction value of 0.37 (0.10, 0.88) mm.
Maxillary sinus floor augmentation using the transalveolar technique is a predictable treatment modality. The augmentation of the maxillary sinus floor using the transalveolar technique could lead to bone formation under the sinus. The newly formed bone showed slight absorbtion in the long term follow-up.
评估采用经牙槽嵴技术在上颌后牙区植入牙种植体的临床和影像学效果。
2005年1月至2009年12月，本研究连续纳入94例患者，其中男性55例，女性39例，年龄（46.9±11.8）岁，均采用经牙槽嵴技术进行上颌窦底提升。每次复诊时均拍摄全景片和根尖片进行影像学评估。随访临床检查包括种植体的累积生存率（CSR）、种植体周围边缘骨丢失（MBL）、上颌窦底提升高度及窦内骨增量（ESBG）。
发现4例发生窦膜穿孔。最终植入126枚种植体（90例患者）。该手术的穿孔率为3.08%（4/130）。4枚种植体在愈合期丢失，种植体早期成功率为96.80%（121/125）。在平均（34.4±20.4）个月的随访期内，所有种植体功能良好，功能加载后的累积生存率为100.00%。愈合期平均MBL为（0.75±0.51）mm，随访期为（0.48±0.41）mm。种植体植入部位的平均剩余骨高度（RBH）为（7.27±1.30）mm，植入窦内的种植体长为（2.77±1.15）mm，上颌窦底提升高度为（4.52±1.39）mm。加载时，平均窦内骨增量为（3.81±1.60）mm。随访34个月后，上颌窦底新形成的骨组织进一步改建，中位骨吸收值为0.37（0.10，0.88）mm。
经牙槽嵴技术进行上颌窦底提升是一种可预测的治疗方式。经牙槽嵴技术提升上颌窦底可导致窦下骨形成。在长期随访中，新形成的骨组织有轻微吸收。
