Various attempts have been implemented using different materials and techniques to augment the maxillary sinus floor for prospect dental implant positioning.
This contemplate was conducted to assess the osteogenic capability of the maxillary sinus in a two-step sinus membrane elevation using titanium mesh to keep the formed space to place dental implants in atrophic ridges.
Titanium micromesh was customized and positioned into the sinus on one side to preserve the elevated membrane in position. On the other side xenograft was applied. Instant and 6-months postoperative cone beam computed tomography (CBCT) was done to assess the gained bone height and density. Bone core biopsies were obtained during implant placement for histological and histomorphometric evaluation.
The average bone height values increased in both groups. Meanwhile the average bone density value was higher at the graft group than the titanium mesh group. Histological and histomorphometric evaluation presented the average bone volume of the newly formed bone in the graft group which is superior to that of the titanium mesh group.
The use of the titanium micromesh as a space-maintaining device after Schneiderian membrane elevation is a trustworthy technique to elevate the floor of the sinus without grafting.
已尝试使用不同材料和技术对上颌窦底进行增高，以利于未来牙种植体的植入。
本研究旨在评估在上颌窦两步法窦膜提升术中，使用钛网保持形成的空间以便在萎缩牙槽嵴中植入牙种植体时，上颌窦的成骨能力。
定制钛微网并将其放置在一侧的窦内，以保持提升的窦膜位置。另一侧应用异种移植物。术后即刻及6个月时进行锥形束计算机断层扫描（CBCT），以评估获得的骨高度和密度。在植入种植体时获取骨芯活检样本，进行组织学和组织形态计量学评估。
两组的平均骨高度值均增加。同时，移植物组的平均骨密度值高于钛网组。组织学和组织形态计量学评估显示，移植物组新形成骨的平均骨体积优于钛网组。
在施奈德膜提升术后使用钛微网作为空间维持装置，是一种无需植骨即可提升窦底的可靠技术。
