Three-dimensional guided lateral window sinus lift and simultaneous implant placement: A dental technique.

Lateral window sinus floor elevation is typically performed blind, and complications may be encountered. Guided surgery can help make the procedure more predictable with fewer complications and a shorter surgical time. The presented technique uses a surgical template for simultaneous implant placement and sinus floor elevation. An implant platform is used for determining the size, shape, and location of the window and the osteotomy depth. The technique uses a Ø5 mm bone profiler with a stop compatible with the surgical guide design to conduct the osteotomy, conservatively guiding the lateral window osteotomy in 3 dimensions.
