This retrospective study investigated whether or not implants can be placed successfully without sinus grafts in atrophic posterior maxillary ridges with < or = 4 mm of bone utilizing the localized management of the sinus floor technique as described by Bruschi and coworkers.
Fifty-eight implants were placed in 34 consecutive patients with an average vertical height of 2.87 mm of residual bone under the sinus. The implants were placed at the time the sinus membrane was elevated.
The sinus was "raised" an average of 9.12 mm without benefit of bone grafts or membranes. The success rate after 22 months of loading was 91.4%.
The localized management of the sinus floor (LMSF) technique permits osseointegration of titanium implants by an endosteal-periosteal continuum that is unhindered by the need of graft material to resorb.
This preliminary study demonstrated that it is possible to place implants in an atrophic alveolar ridge with < or = 4 mm of bone without the need for a traditional sinus graft.
本回顾性研究探讨了采用Bruschi及其同事所描述的窦底局部处理技术,在骨量≤4mm的萎缩性上颌后牙嵴中不进行窦底植骨能否成功植入种植体。
在34例连续患者中植入58枚种植体,窦下平均剩余骨垂直高度为2.87mm。种植体在窦膜提升时植入。
在未使用骨移植或膜的情况下,窦平均“提升”了9.12mm。加载22个月后的成功率为91.4%。
窦底局部处理(LMSF)技术通过骨内膜-骨膜连续体实现钛种植体的骨整合,不受移植材料吸收需求的阻碍。
这项初步研究表明,在骨量≤4mm的萎缩性牙槽嵴中植入种植体而无需传统的窦底植骨是可行的。
