Bone tissue atrophy may constitute a relative contraindication for implantation. The methods used in reconstruction of the alveolar ridge within the lateral section of the maxilla have been well known but not perfect. Presentation of the two-stage, closed sinus lift technique as well as efficacy evaluation of reconstruction of the alveolar ridge in the maxilla within its vertical dimension with the use of this technique. The total procedure was performed in 26 out of 28 patients qualified for the study. The height of the alveolar ridge at the site of the planned implantation was no <3 mm, the width of the ridge was no <5 mm. During the treatment stage 1 the sinus lift was performed for the first time. The created hollow was filled with allogeneic granulate. After 3-6 months stage 2 was performed consisting in another sinus lift with simultaneous implantation. The treatment was completed with prosthetic restoration after 6 months of osteointegration. In 24 out of 26 cases stage 1 was completed with the average ridge height of 7.2 mm. In stage 2, simultaneously with the second sinus lift, 26 implants were placed and no cases of sinusitis were found. In the follow-up period none of the implants were lost. The presented method is efficient and combines the benefits of the open technique-allowing treatment in cases of larger reduction of the vertical dimension and the closed technique-as it does not require opening of the maxillary sinus.
骨组织萎缩可能构成植入的相对禁忌证。上颌外侧部分牙槽嵴重建所使用的方法已为人熟知但并不完美。介绍两阶段闭合式上颌窦提升技术以及使用该技术对上颌垂直方向牙槽嵴重建的疗效评估。在28名符合研究条件的患者中,有26名患者完成了整个手术。计划植入部位的牙槽嵴高度不小于3毫米,牙槽嵴宽度不小于5毫米。在治疗的第一阶段首次进行上颌窦提升。所形成的空洞用同种异体颗粒填充。3至6个月后进行第二阶段,包括再次进行上颌窦提升并同时植入。在骨整合6个月后通过修复性修复完成治疗。在26例中的24例中,第一阶段完成时牙槽嵴平均高度为7.2毫米。在第二阶段,在再次进行上颌窦提升的同时植入了26枚种植体,未发现鼻窦炎病例。在随访期间,没有种植体丢失。所介绍的方法是有效的,它结合了开放技术(允许在垂直尺寸大幅减小的情况下进行治疗)和闭合技术的优点(因为它不需要打开上颌窦)。
