To report on the use of angled implants placed into the vomer/nasal crest to support a complete-arch maxillary prosthesis.
Consecutive patients were treated with the All-on-Four concept to restore the maxillary dentition. When bone volume in the subnasal region was inadequate, angled implants were placed into the vomer/nasal crest area to support the restoration. All implants were loaded immediately.
One hundred consecutive maxillary All-on-Four patients were treated over a period of 2 years. Four hundred six implants were placed; 12 were inserted into the vomer/nasal crest area. One year later, at definitive restoration, the 12 vomer implants were found to be osseointegrated without bone loss or instability.
Midline maxillary bone volume at the nasal crest appeared to be a viable alternative to the lateral nasal rim when subnasal bone was deficient. Vomer implants allowed for immediate function or were sometimes used as a rescue implant when an anterior implant failed.
报告使用成角度的植入物放置到犁骨/鼻嵴以支撑全上颌义齿。
连续的患者接受了 All-on-Four 概念来修复上颌牙齿。当下鼻区的骨量不足时，将成角度的植入物放置到犁骨/鼻嵴区域以支撑修复体。所有植入物都立即加载。
在 2 年的时间里，连续治疗了 100 例上颌 All-on-Four 患者。共植入 406 个种植体，其中 12 个种植体植入到犁骨/鼻嵴区域。一年后，在最终修复时，12 个犁骨种植体被发现已骨整合，没有骨丢失或不稳定。
当中线鼻嵴的上颌骨量在颏下骨量不足时，似乎是侧鼻嵴的可行替代方案。犁骨种植体允许立即功能，或者在前部种植体失败时有时用作救援种植体。
