Abstract:
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.
