The placement of dental implants in the pterygomaxillary region can be advantageous in maxillary complete arch fixed implant-supported prosthetic rehabilitations to avoid bone grafting and sinus elevation surgeries. Pterygomaxillary implants improve implant biomechanics by eliminating distal cantilevers and increasing the anteroposterior spread with reported mean implant survival rates comparable to traditional implant sites. Although only minor surgical complications have been reported in the literature with the placement of dental implants in the pterygomaxillary region this clinical report describes a major surgical complication involving the displacement of a dental implant into the pterygoid fossa.

在上颌完全弓固定植入物支持的假体康复中,在翼状翼状区域放置牙科植入物可能是有利的,以避免植骨和鼻窦抬高手术。翼状翼状植入物通过消除远端悬臂并增加前后扩散来改善植入物的生物力学,据报道,平均植入物存活率可与传统植入物部位相媲美。尽管在文献中仅报道了在翼状翼状区域放置牙科植入物的较小的手术并发症,但该临床报告描述了一种主要的手术并发症,涉及将牙科植入物移位到翼状窝中。
