The sheet summarizes a case published in 2017 in Case Reports in Dentistry in which a Bioteck equine bone substitute consisting of a 1:1 mixture of cancellous and cortical granules, sized 0.5-1 mm (Osteoxenon, Bioteck) was used for a procedure called Low Window and entails a design based on CBCT scans to produce an appropriate template. It also involves placing the window as low and as mesial as possible: that is, with the lower side flush with the floor and the mesial one flush with the anterior sinus wall. The window is invariably 6 mm high. The only variable portion is the distal demarcation line, which coincides with the most distal implant position. In the author’s experience, this approach significantly decreases intraoperative time, patient discomfort – as it requires opening a smaller flap – and above all, the likelihood of tearing the sinus membrane due to the different access angles permitted to surgical instruments.
