Abstract:Aim of this investigation is to show in sites with less than 4mm of bone
height of the sinus floor, synthetic putty bone graft and simultaneous
short implant placement in crestal sinus lifting procedures result in
sufficient bone gain, and is a valuable option to the more invasive
lateral-window approach.
“…Most studies indicate that 80-90 percent is absorbed within 4-6 months, while regenerating bone at the same time. The putty has consistently proven to regenerate bone when used for socket grafting, grafting of periodontal defects or in crestal sinus lift procedures [10,11,12,13,14].…”

Introduction: Aim of this investigation is to show that in sites with less than 4 mm of bone height of the sinus floor, synthetic putty bone graft and simultaneous short implant placement in crestal sinus lifting procedures result in sufficient bone gain, and is a valuable option to the more invasive lateral-window approach.
Case presentation: Four patients missing a single tooth or more in the posterior maxilla with remaining alveolar ridge height of less than 4mm underwent crestal sinus lift procedures with bone grafting using a synthetic putty material simultaneously. Loading of the short implants was done with a minimum of 4 months after placement showing bone growth around the implant and lift of the Schneiderian membrane between 2.3mm-7.3mm.
Conclusion: Crestal sinus lift, in combination with a short implant and a synthetic putty bone graft, is a good alternative for lateral more invasive sinus lift when the thickness of the sinus floor is less than 4mm.
