Summary
Why are these cases new information?
To the best of our knowledge, this is the first report of the use of synthetic putty and simultaneous short implant placement in crestal sinus lifting procedures. Making it possible to simply place short implants in cases where there is 4mm or less of bone height to the sinus floor.
What are the keys to successful management of these cases?
The key to a successful crestal approach is the gentle tapping of the sinus floor with the osteotome and lifting the membrane through hydraulic pressure. The putty is of a decent particle distribution size and reduces the risk of tearing Schneiderian membrane
What are the primary limitations to success in these cases?
Operator inexperience, technique sensitivity of crestal approach using an osteotome rupturing the Schneiderian membrane
